PM: AVS: Drop the avs directory and the corresponding Kconfig

2020-10-22T16:39:32Z

All avs drivers have now been moved to their corresponding soc specific directories. Additionally, they don't depend on the POWER_AVS Kconfig anymore. Therefore, let's simply drop the drivers/power/avs directory altogether. Cc: Nishanth Menon Signed-off-by: Ulf Hansson Reviewed-by: Nishanth Menon Signed-off-by: Rafael J. Wysocki

PM: AVS: qcom-cpr: Move the driver to the qcom specific drivers

2020-10-22T16:38:21Z

The avs drivers are all SoC specific drivers that doesn't share any code. Instead they are located in a directory, mostly to keep similar functionality together. From a maintenance point of view, it makes better sense to collect SoC specific drivers like these, into the SoC specific directories. Therefore, let's move the qcom-cpr driver to the qcom directory.

power: avs: qcom-cpr: Avoid clang -Wsometimes-uninitialized in cpr_scale

2020-01-31T10:07:43Z

Clang warns (trimmed for brevity): ../drivers/power/avs/qcom-cpr.c:570:13: warning: variable 'reg_mask' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] ../drivers/power/avs/qcom-cpr.c:520:13: warning: variable 'new_uV' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] Due to the fact that Clang's static analysis happens before any optimization passes are taken into account, it cannot see that both branches in the if statement must be taken because dir cannot be something other than UP or DOWN due to the check at the top of this function. Change the else if condition to else to fix this false positive.

power: avs: qcom-cpr: add unspecified HAS_IOMEM dependency

2020-01-31T10:07:43Z

Currently CONFIG_QCOM_CPR=y implicitly depends on CONFIG_HAS_IOMEM=y; consequently, on architectures without IOMEM we get the following build error: /usr/bin/ld: drivers/power/avs/qcom-cpr.o: in function `cpr_probe': drivers/power/avs/qcom-cpr.c:1690: undefined reference to `devm_ioremap_resource' Fix the build error by adding the unspecified dependency.

PM / AVS: rockchip-io: fix the supply naming for the emmc supply on px30

2020-01-31T10:07:43Z

The supply going to the emmc/flash is named vccio6, not vccio0 and while the code does this correctly already, the comments and error output do not. So just change these values to the correct ones. Signed-off-by: Heiko Stuebner Signed-off-by: Rafael J. Wysocki

In order to easier inform the user that the driver has been initialized successfully, add a printout after the driver has been initialized. At the same time, remove a dev_dbg() that is now redundant. Signed-off-by: Niklas Cassel Reviewed-by: Bjorn Andersson Signed-off-by: Rafael J. Wysocki
