PM / devfreq: rk3399_dmc: Pass ODT and auto power down parameters to TF-A.

2019-04-16T00:29:18Z

Trusted Firmware-A (TF-A) for rk3399 implements a SiP call to get the on-die termination (ODT) and auto power down parameters from kernel, this patch adds the functionality to do this. Also, if DDR clock frequency is lower than the on-die termination (ODT) disable frequency this driver should disable the DDR ODT.

Some rk3399 GRF (Generic Register Files) definitions can be used for different drivers. Move these definitions to a common include so we don't need to duplicate these definitions. Signed-off-by: Enric Balletbo i Serra Acked-by: Chanwoo Choi Signed-off-by: Gaël PORTAY Signed-off-by: MyungJoo Ham

PM / devfreq: exynos-bus: Suspend all devices on system shutdown

2019-04-16T00:29:18Z

Force all Exynos buses to safe operation points before doing the system reboot operation. There are board on which some aggressive power saving operation points are behind the capabilities of the bootloader to properly reset the hardware and boot the board. This way one can avoid board crash early after reboot. This fixes reboot issue on OdroidU3 board both with eMMC and SD boot.

PM / devfreq: Fix static checker warning in try_then_request_governor

2019-04-16T00:29:18Z

The patch 23c7b54ca1cd: "PM / devfreq: Fix devfreq_add_device() when drivers are built as modules." leads to the following static checker warning: drivers/devfreq/devfreq.c:1043 governor_store() warn: 'governor' can also be NULL The reason is that the try_then_request_governor() function returns both error pointers and NULL. It should just return error pointers, so fix this by returning a ERR_PTR to the error intead of returning NULL. Fixes: 23c7b54ca1cd ("PM / devfreq: Fix devfreq_add_device() when drivers are built as modules.")
