2022-07-07soc: mediatek: SVS: Use DEFINE_SIMPLE_DEV_PM_OPS for svs_pm_opsNathan Chancellor
When building this driver for an architecture that does not support CONFIG_PM_SLEEP, such as hexagon, the following warnings occur: drivers/soc/mediatek/mtk-svs.c:1481:12: error: unused function 'svs_suspend' [-Werror,-Wunused-function] static int svs_suspend(struct device *dev) ^ drivers/soc/mediatek/mtk-svs.c:1515:12: error: unused function 'svs_resume' [-Werror,-Wunused-function] static int svs_resume(struct device *dev) ^ 2 errors generated. This happens because SIMPLE_DEV_PM_OPS uses SET_SYSTEM_SLEEP_PM_OPS, which evaluates to nothing when CONFIG_PM_SLEEP is not set, leaving the functions unused in the eyes of the compiler. This problem was rectified in commit 1a3c7bb08826 ("PM: core: Add new *_PM_OPS macros, deprecate old ones") with new macros. Use DEFINE_SIMPLE_DEV_PM_OPS to fix the warning while not changing svs_pm_ops when CONFIG_PM_SLEEP is set.

This also ensures that the SRAM is actually powered and that we're not relying on the bootloader leaving this supply on when performing the first (and latter) poweron sequence for these domains' sram.

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/drivers Arm SCMI updates for v5.20 The main additions this time around are: 1. The capability to trace full SCMI message headers and payloads. The recent unearthing of chain of old firmware issues motivated this effort so that it is easier to trace them and debug quicker than it took this time around in absence of such tracing. 2. SCMI System power control driver to handle platform's requests for a graceful shutdown. Though the system power control protocol has been around since the begining of SCMI, it lacked the timeout information that was added in SCMI v3.1 that enables kernel to take appropriate action within the timeout and doesn't have to rely on any other user inputs(which was blocking factor for addition of this driver earlier) 3. Support for SCMI Power Capping protocol that was introduced in SCMI v3.1 This protocol is intended for controlling and monitoring the power consumption of power capping domains. The firmware also provides the hierarchy of powercap domains by providing parent domain information. It also contains a bug fix in the old SCPI driver addressing possible user-after-free issues. * tag 'scmi-updates-5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scmi: Use fast channel tracing include: trace: Add SCMI fast channel tracing firmware: arm_scmi: Add SCMI v3.1 powercap fast channels support firmware: arm_scmi: Generalize the fast channel support firmware: arm_scmi: Add SCMI v3.1 powercap protocol basic support dt-bindings: firmware: arm,scmi: Add support for powercap protocol firmware: arm_scmi: Add SCMI System Power Control driver firmware: arm_scmi: Add devm_protocol_acquire helper firmware: arm_scmi: Add SCMI v3.1 System Power extensions firmware: arm_scmi: Support only one single system power device firmware: arm_scmi: Use new SCMI full message tracing include: trace: Add SCMI full message tracing firmware: arm_scpi: Ensure scpi_info is not assigned if the probe fails firmware: arm_scmi: Remove usage of the deprecated ida_simple_xxx API firmware: arm_scmi: Fix response size warning for OPTEE transport firmware: arm_scmi: Relax CLOCK_DESCRIBE_RATES out-of-spec checks Link: https://lore.kernel.org/r/20220706115045.2272678-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2022-06-27soc: fsl: guts: add serial_number supportMichael Walle
Most layerscapes provide a security fuse processor where the vendor will store a unique id per part. Unfortunately, we cannot use the corresponding efuse driver because this driver needs to be ready early during the boot phase. To get the unique identifier, we just need to access two registers. Thus we just search the device tree for the corresponding device, map its memory to read the id and then unmap it again. Because it is likely that the offset within the fuses is dependent on the SoC, we need a per SoC data. Also, the compatible string is different among the SoCs. For now, this add support for the LS1028A SoC. Signed-off-by: Michael Walle <michael@walle.cc> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2022-06-27soc: fsl: guts: drop platform driverMichael Walle
This driver cannot be unloaded and it will be needed very early in the boot process because other driver (weakly) depend on it (eg. for chip errata handling). Drop all the platform driver and devres stuff and simply make it a core_initcall.

2022-06-27soc: fsl: guts: use of_root instead of own referenceMichael Walle
There is already a global of_root reference. Use that instead of getting one on our own. We don't need to care about the reference count either this way. Signed-off-by: Michael Walle <michael@walle.cc> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

This is the last global static variable. Drop it and allocate the memory on the heap instead. Signed-off-by: Michael Walle <michael@walle.cc> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2022-06-27soc: fsl: guts: embed fsl_guts_get_svr() in probe()Michael Walle
Move the reading of the SVR into the probe function as fsl_guts_get_svr() is the only user of the static guts variable and this lets us drop that as well as the malloc() for this variable. Also, we can unmap the memory region after we accessed it, which will simplify error handling later.

2022-06-27soc: fsl: guts: remove module_exit() and fsl_guts_remove()Michael Walle
This driver will never be unloaded. Firstly, it is not available as a module, but more importantly, other drivers will depend on this one to apply possible chip errata.
