into drm-next
This series adds a deadline hint to fences, so realtime deadlines
such as vblank can be communicated to the fence signaller for power/
frequency management decisions.
This is partially inspired by a trick i915 does, but implemented
via dma-fence for a couple of reasons:
1) To continue to be able to use the atomic helpers
2) To support cases where display and gpu are different drivers
See https://patchwork.freedesktop.org/series/93035/
This does not yet add any UAPI, although this will be needed in
a number of cases:
1) Workloads "ping-ponging" between CPU and GPU, where we don't
want the GPU freq governor to interpret time stalled waiting
for GPU as "idle" time
2) Cases where the compositor is waiting for fences to be signaled
before issuing the atomic ioctl, for example to maintain 60fps
cursor updates even when the GPU is not able to maintain that
framerate.

As the finished fence is the one that is exposed to userspace, and
therefore the one that other operations, like atomic update, would
block on, we need to propagate the deadline from from the finished
fence to the actual hw fence.
v2: Split into drm_sched_fence_set_parent() (ckoenig)
v3: Ensure a thread calling drm_sched_fence_set_deadline_finished() sees
fence->parent set before drm_sched_fence_set_parent() does this
test_bit(DMA_FENCE_FLAG_HAS_DEADLINE_BIT).

It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

A patch series for moving MIPI-DSI driver for Exynos DRM to drm/bridge
directory so that I.MX SoC family can also share the same device driver.
Samsung MIPI DSIM device is a common IP that can be used by Exynos and I.MX8M
Mini/Nano/Plus SoC. Regarding this, this patch series has added several
things below to existing MIPI DSI driver,
- Add exynos_dsi_type enum type to provide controller data from different
platforms.
- Add two pipeline detection ways support - existing Exynos DSI child node
and I.MX family of-graph port or ports.
- Consider component and bridged based DRM drivers.
- Add device tree binding support of I.MX family.

Samsung MIPI DSIM controller is common DSI IP that can be used in various
SoCs like Exynos, i.MX8M Mini/Nano.
In order to access this DSI controller between various platform SoCs,
the ideal way to incorporate this in the drm stack is via the drm bridge
driver.
We already have a consolidated code for supporting component and bridge
based DRM drivers, so keep the exynos component based code in existing
exynos_drm_dsi.c and move generic bridge code as part of samsung-dsim.c

IRQ handler for te-gpio seems to be common across DSIM host.
However, Exynos is handling this via CRTC drivers but there is no clear
evidence on how the same has been handled in i.MX8MM. Keeping the handler
as-it-is can be a viable option but adding DSIM bridge core in upcoming
patches is not possible to call Exynos CRTC handler as DSIM bridge has
to be common across DRM bridge core instead of platform specific DRM
drivers like Exynos here.
So, this patch handles the handler via platform host helper, so-that
handling platform specific hook across Exynos and generic can be
reasonable till it makes it generic across all platforms.

DSI host registration, attach and detach operations are quite
different for the component and bridge-based DRM drivers.
Supporting generic bridge driver to use both component and bridge

related operation hooks.
Add host operation hooks for registering and unregistering Exynos
and generic drivers, where Exynos hooks are used in existing Exynos
component based DRM drivers and generic hooks are used in i.MX8M
bridge based DRM drivers.
Add host attach and detach operation hooks for Exynos component
DRM drivers and those get invoked while DSI core host attach and
detach gets called.

Look like an explicit fixing up of mode_flags is required for DSIM IP
present in i.MX8M Mini/Nano SoCs.
At least the LCDIF + DSIM needs active low sync polarities in order
to correlate the correct sync flags of the surrounding components in
the chain to make sure the whole pipeline can work properly.
On the other hand the i.MX 8M Mini Applications Processor Reference Manual,
Rev. 3, 11/2020 says.
"13.6.3.5.2 RGB interface
Vsync, Hsync, and VDEN are active high signals."
i.MX 8M Mini Applications Processor Reference Manual Rev. 3, 11/2020
3.6.3.5.2 RGB interface

13.6.2.7.2 RGB interface
both claim "Vsync, Hsync, and VDEN are active high signals.", the
LCDIF must generate inverted HS/VS/DE signals, i.e. active LOW.
No clear evidence about whether it can be documentation issues or
something, so added proper comments on the code.

Host transfer() in the DSI master will invoke only when the DSI commands
are sent from DSI devices like DSI Panel or DSI bridges and this host
the transfer wouldn't invoke for I2C-based-DSI bridge drivers.
Handling DSI host initialization in transfer calls misses the controller
setup for I2C configured DSI bridges.
This patch updates the DSI host initialization by calling host to init
from bridge pre_enable as the bridge pre_enable API is invoked by core
as it is common across all classes of DSI device drivers.
The host init during pre_enable is conditional and not invoked for Exynos
as existing downstream drm panels and bridges in Exynos are expecting
the host initialization during DSI transfer.

Look like PLL PMS_P offset value varies between platforms that have
Samsung DSIM IP.
However, there is no clear evidence for it as both Exynos and i.MX
8M Mini Application Processor Reference Manual is still referring
the PMS_P offset as 13.
The offset 13 is not working for i.MX8M Mini SoCs but the downstream
NXP sec-dsim.c driver is using offset 14 for i.MX8M Mini SoC platforms
[1] [2].
PMS_P value set in sec_mipi_dsim_check_pll_out using PLLCTRL_SET_P()
with offset 13 and then an additional offset of one bit added in
sec_mipi_dsim_config_pll via PLLCTRL_SET_PMS().
Not sure whether it is reference manual documentation or something
else but this patch trusts the downstream code and handle PLL_P offset
via platform driver data so-that imx8mm driver data shall use
pll_p_offset to 14.
Similar to Mini the i.MX8M Nano/Plus also has P=14, unlike Exynos.

In general, for MIPI DSI there are three ways to represent the
pipeline for an upstream bridge to find the connected downstream
panel or bridge.
1. Child panel or bridge as a conventional device tree child node.
2. Child panel or bridge as an OF-graph port node.
3. Child panel or bridge as an OF-graph ports node.
There are three different downstream panels or bridges that are
possible to connect an upstream DSI host bridge - DSI Panel,
DSI Bridge, and I2C-Configured DSI bridge.
An example of the downstream panel represented as a child node,
&dsi {
compatible = "samsung,exynos5433-mipi-dsi";
ports {
port@0 {
reg = <0>;
dsi_to_mic: endpoint {
remote-endpoint = <&mic_to_dsi>;
};
};
};
panel@0 {
reg = <0>;
};
};
An example of the downstream bridge represented as a port node,
&i2c4 {
bridge@2c {
compatible = "ti,sn65dsi84";
ports {
port@0 {
reg = <0>;
bridge_in_dsi: endpoint {
remote-endpoint = <&dsi_out_bridge>;
data-lanes = <1 2>;
};
};
port@2 {
reg = <2>;
bridge_out_panel: endpoint {
remote-endpoint = <&panel_out_bridge>;
};
};
};
};
};
&dsi {
compatible = "fsl,imx8mm-mipi-dsim";
port {
dsi_in_lcdif: endpoint@0 {
reg = <0>;
remote-endpoint = <&lcdif_out_dsi>;
};
dsi_out_bridge: endpoint@1 {
reg = <1>;
remote-endpoint = <&bridge_in_dsi>;
};
};
};
An example of the downstream bridge represented as a ports node,
&dsi {
compatible = "fsl,imx8mm-mipi-dsim";
ports {
port@0 {
reg = <0>;
dsi_in_lcdif: endpoint@0 {
reg = <0>;
remote-endpoint = <&lcdif_out_dsi>;
};
};
port@1 {
reg = <1>;
dsi_out_bridge: endpoint {
remote-endpoint = <&bridge_in_dsi>;
};
};
};
In, summary it is possible to represent all three downstream slaves
devices using OF-graph port or ports node however only DSI Panel and
DSI Bridge are possible but not possible to represent I2C-Configured
DSI bridge child nodes since I2C-Configure bridges are child of I2C
node, not upstream DSI host bridge and it is must represent them
endpoint port linking.
This indeed means, the OF-graph port or ports representation is
mandatory for I2C-Configured DSI bridges.
This patch tries to add an OF-graph port or ports representation
detection code on top of existing child node detection.
It is possible to replace the entire detection code using existing
drm_of helper drm_of_find_panel_or_bridge but it will break the
Exynos DSI since the pipeline doesn't support OF-graph port or ports
node.
Overall, this patch has a combination of child and OF-graph pipeline
detections in order to support the backward compatibility of Exynos
DSI child node and i.MX8M Mini/Nano/Plus OF-graph port or ports
node pipelines.
This is the first common DSI host bridge driver that needs to support
all possible downstream connection pipeline combinations.

The DORCR register controls the routing of clocks and data between DU
channels within a group. For groups that contain a single channel,
there's no routing option to control, and some fields of the register
are then reserved. On Gen2 those reserved fields are documented as
required to be set to 0, while on Gen3 and newer the PG1T, DK1S and PG1D
reserved fields must be set to 1.
The DU driver initializes the DORCR register in rcar_du_group_setup(),
where it ignores the PG1T, DK1S and PG1D, and then configures those
fields to the correct value in rcar_du_group_set_routing(). This hasn't
been shown to cause any issue, but prevents certifying that the driver
complies with the documentation in safety-critical use cases.
As there is no reasonable change that the documentation will be updated
to clarify that those reserved fields can be written to 0 temporarily
before starting the hardware, make sure that the registers are always
set to valid values.

The DORCR fields were documented in the R-Car H1 datasheet with 1-based
named, and then got renamed to 0-based in Gen2. The 0-based names are
used for Gen3 and Gen4, making H1 an outlier. Rename the field macros to
make them 0-based, in order to increase readability of the code when
comparing it with the documentation.

The ESCR and OTAR registers are not present in all DU channels on Gen3
SoCs. ESCR only exists in channels that can be routed to an LVDS or
DPAD, and OTAR in channels that can be routed to a DPAD. Skip writing
those registers for other channels. This replaces the DU gen check, as
Gen4 doesn't have LVDS or DPAD outputs.

On R-Car D3 and E3, the LVDS encoder provides the dot (pixel) clock to
the DU, regardless of whether the LVDS output is used or not. When using
the DPAD (RGB) output, the DU driver thus enables and disables the LVDS
PLL manually, while when using the LVDS output, it lets the LVDS bridge
driver handle the PLL configuration internally as part of the atomic
enable and disable operations.
This causes an issue when using the LVDS output. As bridges are disabled
before CRTCs, the current implementation violates the enable/disable
sequences documented in the hardware datasheet, which requires the dot
clock to be enabled before the CRTC is started and disabled after it
gets stopped.
Fix the problem by enabling/disabling the LVDS PLL manually from the DU
regardless of which output is used, and skipping the PLL handling in the
LVDS bridge atomic enable and disable operations.
This is however not enough. Disabling the LVDS encoder while leaving the
PLL on still results in a vertical blanking wait timeout when disabling
the DU. Investigation showed that the culprit is the LVEN bit. For an
unclear reason, clearing the bit when disabling the LVDS encoder blocks
vertical blanking interrupts. We thus have to delay disabling the whole
LVDS encoder, not just disabling the PLL, until the DU is disabled.
We could split the LVDS disable sequence by clearing the LVRES bit in
the LVDS bridge atomic disable handler, and delaying the rest of the
operations, in order to disable the LVDS output at bridge atomic disable
time, before stopping the CRTC. This would make the code more complex,
without a clear benefit, so keep the implementation simple(r).

To prepare for a rework of the LVDS disable code, which will need to be
called from rcar_lvds_pclk_disable(), move the LVDS enable code,
currently stored in the __rcar_lvds_atomic_enable() function, to a
separate code section separate from bridge operations. It will be then
extended with the LVDS disable code.
As part of this rework the __rcar_lvds_atomic_enable() function is
renamed to rcar_lvds_enable() to more clearly indicate its purpose.
No functional change intended.

Pull xfs percpu counter fixes from Darrick Wong:
"We discovered a filesystem summary counter corruption problem that was
traced to cpu hot-remove racing with the call to percpu_counter_sum
that sets the free block count in the superblock when writing it to
disk. The root cause is that percpu_counter_sum doesn't cull from
dying cpus and hence misses those counter values if the cpu shutdown
hooks have not yet run to merge the values.
I'm hoping this is a fairly painless fix to the problem, since the
dying cpu mask should generally be empty. It's been in for-next for a
week without any complaints from the bots.

Pull xfs fixes from Darrick Wong:
"This batch started with some debugging enhancements to the new
allocator refactoring that we put in 6.3-rc1 to assist developers in

As for more serious code changes -- there's a bug fix to make the
lockless allocator scan the whole filesystem before resorting to the
locking allocator. We're also adding a selftest for the venerable
directory/xattr hash function to make sure that it produces consistent
results so that we can address any fallout as soon as possible.
- Add a few debugging assertions so that people (me) trying to port
code to the new allocator functions don't mess up the caller
requirements
- Relax some overly cautious lock ordering enforcement in the new
allocator code, which means that file allocations will locklessly
scan for the best space they can get before backing off to the
traditional lock-and-really-get-it behavior
- Add tracepoints to make it easier to trace the xfs allocator
behavior
- Actually test the dir/xattr hash algorithm to make sure it produces
