soc: rockchip: io-domain: add rk3568 support

2021-08-14T06:23:47+00:00

The io-domain registers on RK3568 SoCs have three separated bits to enable/disable the 1.8v/2.5v/3.3v power. This patch make the write to be a operation, allow rk3568 uses a private register set function. Since the 2.5v mode hasn't been fully validated yet, the driver only sets 1.8v [enable] + 3.3v [disable] for 1.8v mode 1.8v [disable] + 3.3v [enable] for 3.3v mode There is not register order requirement which has been cleared by our IC team. For future reference the full usage matrix including the 2.5V setting is: case V33 V25 V18 result 0 0 0 0 IO safe, but cannot work 1 0 0 1 IO require 1.8V, should < 1.98V, otherwise IO may damage 2 0 1 0 IO require 2.5V, should < 2.75V, otherwise IO may damage 3 0 1 1 Invalid state, should avoid 4 1 0 0 IO require 3.3V, should < 3.63V, otherwise IO may damage 5 1 0 1 IO require 1.8V, should < 1.98V, otherwise IO may damage 6 1 1 0 IO require 2.5V, should < 2.75V, otherwise IO may damage 7 1 1 1 Invalid state, should avoid Signed-off-by: Jianqun Xu Tested-by: Peter Geis [added mode clarification from Jay] Link: https://lore.kernel.org/r/20210805120107.27007-3-michael.riesch@wolfvision.net Signed-off-by: Heiko Stuebner

soc: rockchip: ROCKCHIP_GRF should not default to y, unconditionally

2021-07-12T11:29:09+00:00

Merely enabling CONFIG_COMPILE_TEST should not enable additional code. To fix this, restrict the automatic enabling of ROCKCHIP_GRF to ARCH_ROCKCHIP, and ask the user in case of compile-testing.

PM: AVS: rockchip-io: Move the driver to the rockchip specific drivers

2020-10-16T16:23:15+00:00

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 rockchip-io driver to the rockchip directory. Signed-off-by: Ulf Hansson Acked-by: Heiko Stuebner Signed-off-by: Rafael J. Wysocki

BIT(status) : 0, \ ^~~~~~~~~~~ include/linux/bits.h:6:24: note: expanded from macro 'BIT' This is a bug in clang that will be fixed in the future, but in order to build cleanly with clang-8, it would be helpful to shut up this warning. This file is the only instance reported by kernelci at the moment. The best solution I could come up with is to move the BIT() usage out of the macro into the instantiation, so we can avoid using BIT(-1).
