soc: rockchip: Fix refcount leak in rockchip_grf_init

2022-06-14T16:32:33+00:00

[ Upstream commit 9b59588d8be91c96bfb0371e912ceb4f16315dbf ] of_find_matching_node_and_match returns a node pointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() to avoid refcount leak.

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

2021-09-15T07:50:31+00:00

[ Upstream commit 2a1c55d4762dd34a8b0f2e36fb01b7b16b60735b ] 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

soc: rockchip: work around clang warning

clang emits a warning about a negative shift count for an unused part of a conditional constant expression: drivers/soc/rockchip/pm_domains.c:795:21: error: shift count is negative [-Werror,-Wshift-count-negative] [RK3328_PD_VIO] = DOMAIN_RK3328(-1, 8, 8, false), ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/soc/rockchip/pm_domains.c:129:2: note: expanded from macro 'DOMAIN_RK3328' DOMAIN_M(pwr, pwr, req, (req) + 10, req, wakeup) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/soc/rockchip/pm_domains.c:105:33: note: expanded from macro 'DOMAIN_M' .status_mask = (status >= 0) ? 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).

soc: rockchip: Set the proper PWM for rk3288

2019-04-11T11:40:32+00:00

The rk3288 SoC has two PWM implementations available, the "old" implementation and the "new" one. You can switch between the two of them by flipping a bit in the grf. The "old" implementation is the default at chip power up but isn't the one that's officially supposed to be used. ...and, in fact, the driver that gets selected in Linux using the rk3288 device tree only supports the "new" implementation. Long ago I tried to get a switch to the right IP block landed in the PWM driver (search for "rk3288: Switch to use the proper PWM IP") but that got rejected. In the mean time the grf has grown a full-fledged driver that already sets other random bits like this. That means we can now get the fix landed. For those wondering how things could have possibly worked for the last 4.5 years, folks have mostly been relying on the bootloader to set this bit. ...but occasionally folks have pointed back to my old patch series [1] in downstream kernels.
