2024-07-03driver core: have match() callback in struct bus_type take a const *Greg Kroah-Hartman
In the match() callback, the struct device_driver * should not be changed, so change the function callback to be a const *. This is one step of many towards making the driver core safe to have struct device_driver in read-only memory. Because the match() callback is in all busses, all busses are modified to handle this properly. This does entail switching some container_of() calls to container_of_const() to properly handle the constant *. For some busses, like PCI and USB and HV, the const * is cast away in the match callback as those busses do want to modify those structures at this point in time (they have a local lock in the driver structure.) That will have to be changed in the future if they wish to have their struct device * in read-only-memory. Cc: Rafael J.

2024-07-01soc: qcom: smp2p: Use devname for interrupt descriptionsChris Lew
When using /proc/interrupts to collect statistics on smp2p interrupt counts, it is hard to distinguish the different instances of smp2p from each other. For example to debug a processor boot issue, the ready and handover interrupts are checked for sanity to ensure the firmware reached a specific initialization stage. Remove "smp2p" string from the irq request so that the irq will default to the device name. Add an .irq_print_chip() callback to print the irq chip name as the device name. These two changes allow for a unique name to be used in /proc/interrupts as shown below. / # cat /proc/interrupts | grep smp2p 18: ... ipcc 196610 Edge smp2p-adsp 20: ... ipcc 131074 Edge smp2p-modem 170: ... smp2p-modem 1 Edge q6v5 ready 178: ... smp2p-adsp 1 Edge q6v5 ready Signed-off-by: Chris Lew <quic_clew@quicinc.com> Reviewed-by: Konrad Dybcio <konrad.dybcio@linaro.org> Link: https://lore.kernel.org/r/20240627104831.4176799-2-quic_sudeepgo@quicinc.com Signed-off-by: Bjorn Andersson <andersson@kernel.org>

2024-06-27drivers/soc/litex: drop obsolete dependency on COMPILE_TESTJean Delvare
Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues. As a minor optimization, this also lets us drop of_match_ptr() and ifdef-guarding, as we now know what they will resolve to, we might as well save cpp some work.

For SoCs like gs101 that need a special regmap, register this with of_syscon_register_regmap api, so it can be returned by syscon_regmap_lookup_by_phandle() and friends. For SoCs that don't require a custom regmap, revert back to syscon creating the mmio regmap rather than duplicating the logic here. exynos_get_pmu_regmap_by_phandle() api is also updated to retrieve the regmap via syscon. The exynos_get_pmu_regmap_by_phandle() api is kept around until fw_devlink support for syscon property is added for the pinctrl-samsung driver that also runs at postcore_initcall level. All other exynos client drivers can revert back to syscon_regmap_lookup_by_phandle().

In this patch, net_dim relies on some NET's interfaces, thus DIMLIB needs to explicitly depend on the NET Kconfig.

Recent (SM8550+ ish) Qualcomm SoCs have a new mechanism for precisely identifying the specific SKU and the precise speed bin (in the general meaning of this word, anyway): a pair of values called Product Code and Feature Code. Based on this information, we can deduce the available frequencies for things such as Adreno. In the case of Adreno specifically, Pcode is useless for non-prototype SoCs. Introduce a getter for the feature code and export it.

Until SM8450, there was only one broadcast region (Broadcast_OR) used to broadcast write and check for status bit 0. >From SM8450 onwards another broadcast region (Broadcast_AND) has been added which checks for status bit 1. This hasn't been updated and Broadcast_OR region was wrongly being used to check for status bit 1 all along. Hence define new regmap structure for Broadcast_AND region and initialize this regmap when HW block version is greater than 4.1, otherwise initialize as a NULL pointer for backwards compatibility.

2024-05-27soc: qcom: rpmh-rsc: Ensure irqs aren't disabled by rpmh_rsc_send_data() callersStephen Boyd
Dan pointed out that Smatch is concerned about this code because it uses spin_lock_irqsave() and then calls wait_event_lock_irq() which enables irqs before going to sleep. The comment above the function says it should be called with interrupts enabled, but we simply hope that's true without really confirming that. Let's add a might_sleep() here to confirm that interrupts and preemption aren't disabled. Once we do that, we can change the lock to be non-saving, spin_lock_irq(), to clarify that we don't expect irqs to be disabled. If irqs are disabled by callers they're going to be enabled anyway in the wait_event_lock_irq() call which would be bad. This should make Smatch happier and find bad callers faster with the might_sleep(). We can drop the WARN_ON() in the caller because we have the might_sleep() now, simplifying the code.
