2012-09-12ARM: OMAP: Split plat/hardware.h, use local soc.h for omap2+Tony Lindgren
As the plat and mach includes need to disappear for single zImage work, we need to remove plat/hardware.h. Do this by splitting plat/hardware.h into omap1 and omap2+ specific files. The old plat/hardware.h already has omap1 only defines, so it gets moved to mach/hardware.h for omap1. For omap2+, we use the local soc.h that for now just includes the related SoC headers to keep this patch more readable. Note that the local soc.h still includes plat/cpu.h that can be dealt with in later patches. Let's also include plat/serial.h from common.h for all the board-*.c files. This allows making the include files local later on without patching these files again. Note that only minimal changes are done in this patch for the drivers/watchdog/omap_wdt.c driver to keep things compiling. Further patches are needed to eventually remove cpu_is_omap usage in the drivers. Also only minimal changes are done to sound/soc/omap/* to remove the unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's no need to include omap44xx.h. While at it, also sort some of the includes in the standard way.

2012-09-12ARM: OMAP2+: Prepare for irqs.h removalTony Lindgren
As the interrupts should only be defined in the platform_data, and eventually coming from device tree, there's no need to define them in header files. Let's remove the hardcoded references to irqs.h and fix up the includes so we don't rely on headers included in irqs.h. Note that we're defining OMAP_INTC_START as 0 to the interrupts. This will be needed when we enable SPARSE_IRQ. For some drivers we need to add #include <plat/cpu.h> for now until these drivers are fixed to remove cpu_is_omapxxxx() usage. While at it, sort som of the includes the standard way, and add the trailing commas where they are missing in the related data structures.

into cleanup-sparseirq Changes for GPMC (General Purpose Memory Controller) that take it closer for being just a regular device driver. Remove the ancient omap specific atags that are no longer needed. At some point we were planning to pass the bootloader information with custom atags that did not work out too well. There's no need for these any longer as the kernel has been booting fine without them for quite some time. And Now we have device tree support that can be used instead.
2012-09-12ARM: OMAP: omap_device: idle devices with no driver boundKevin Hilman
Under some circumstances, drivers may leave an omap_device enabled due to driver programming errors, or due to a failure in the drivers probe method. Using the recently added omap_device driver_status field, we can detect conditions where an omap_device is enabled but has no driver bound and then ensure that the device is properly idled until it can be probed again. The goal of this feature is not only to detect and warn on these error conditions, but also to ensure that devices are properly put in low-power states so they do not prevent SoC-wide low-power states.

2012-09-12ARM: OMAP: omap_device: don't attempt late suspend if no driver boundKevin Hilman
Currently, the omap_device PM domain layer uses the late suspend and early resume callbacks to ensure devices are in their low power states. However, this is attempted even in cases where a driver probe has failed. If a driver's ->probe() method fails, the driver is likely in a state where it is not expecting its runtime PM callbacks to be called, yet currently the omap_device PM domain code attempts to call the drivers callbacks. To fix, use the omap_device driver_status field to check whether a driver is bound to the omap_device before attempting to trigger driver callbacks.

This patch adds HWMOD data for all the peripherals of AM335X device and also hooks up to the existing OMAP framework. hwmod data has been already been cleaned up for the recent changes in clocktree, where all leaf nodes have been removed, since with modulemode based control, both clock and hwmod interface does same thing. This reduces the code size to large extent and also avoids duplication of same control. So instead of specifying module's leaf node as a main_clk, now we are relying on parent clock of module's functional clock.

With the new devices (like, AM33XX and OMAP5) we now only support DT boot mode of operation and now it is the time to start killing slowly the dependency on hwmod, so with this patch, we are starting with device resources. The idea here is implemented considering to both boot modes - - DT boot mode OF framework will construct the resource structure (currently does for MEM & IRQ resource) and we should respect/use these resources, killing hwmod dependency. If pdev->num_resources > 0, we assume that MEM & IRQ resources have been allocated by OF layer already (through DTB). Once DMA resource is available from OF layer, we should kill filling any resources from hwmod. - Non-DT boot mode Here, pdev->num_resources = 0, and we should get all the resources from hwmod (following existing steps) Signed-off-by: Vaibhav Hiremath <hvaibhav@ti.com> Cc: Tony Lindgren <tony@atomide.com> Cc: Paul Walmsley <paul@pwsan.com> Cc: Kevin Hilman <khilman@ti.com> [b-cousson@ti.com: Fix some checkpatch CHECK issues] Signed-off-by: Benoit Cousson <b-cousson@ti.com>

When booted with some resource will have their name set to NULL. This can cause later kernel crash since this is not expected by the platform code. When we boot without DT the devices are created with platform_device_add() which itself fixes up the missing resource names: if (r->name == NULL) r->name = dev_name(&pdev->dev); The of core also fixes up the resource names when taking the information from DT data - in __of_address_to_resource(): r->name = name ? name : dev->full_name; When we boot OMAP with devicetree: of will create the devices based on the DT data so the resource names are guarantied to be not NULL. Since we have the 'ti,hwmod' tag, we remove the of created resources from the device and re-create them based on hwmod data. If the hwmod data does not specify a name for a resource it will be NULL. This can cause kernel crash if the driver uses platform_get_resource_byname() to get any resource.

If, for whatever reason, someone puts another member as the first of the structure, that cast won't work anymore. In order to be safe, let's use a container_of() which, for now, gets optimized into a cast anyway.

2012-08-30ARM: OMAP: sram: skip the first 16K on OMAP3 HSAaro Koskinen
In some OMAP3 HS devices (at least Nokia N9 and N950), the public SRAM seems to conflict with secure portition of SRAM. When booting the 3.6-rc3 kernel (and also earlier) on these devices, the kernel gets tainted with tons of the following warnings: [ 6.894348] In-band Error seen by MPU at address 0 [...] [ 6.894378] WARNING: at arch/arm/mach-omap2/omap_l3_smx.c:162 Fix this by skipping the first 16K of the public SRAM. (Note that the mapping could not be changed, as it resulted in secure monitor call failure in save_secure_sram().) This will leave 12K SRAM available that should be still sufficient. The patch has been boot tested with vanilla 3.6-rc3 on N900, N950 and N9.

OMAP4-specific code should be executed only if we are running on OMAP4. Otherwise it may break multi-OMAP kernels. Found by reading the code. Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Acked-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2012-08-30ARM: OMAP2+: gpmc: Modify interrupt handlingAfzal Mohammed
Modify interrupt handling such that interrupts can be handled by GPMC client drivers using standard interrupt APIs rather than requiring the drivers to have knowledge about GPMC interrupt handling. Currently only NAND related interrupts has been considered (which is the case even without this change) as the only user of GPMC interrupt is NAND.

2012-08-30mtd: nand: omap2: obtain memory from resourceAfzal Mohammed
gpmc initialization done by platform code now updates struct resource with the address space alloted for nand. Use this interface to obtain memory rather than relying on platform data field - phys_base.

2012-08-20workqueue: deprecate flush[_delayed]_work_sync()Tejun Heo
flush[_delayed]_work_sync() are now spurious. Mark them deprecated and convert all users to flush[_delayed]_work(). If you're cc'd and wondering what's going on: Now all workqueues are non-reentrant and the regular flushes guarantee that the work item is not pending or running on any CPU on return, so there's no reason to use the sync flushes at all and they're going away. This patch doesn't make any functional difference.
