soc: rockchip: grf: Support multiple grf to be handled

2026-03-04T12:21:14+00:00

[ Upstream commit 75fb63ae031211e9264ac888fabc2ca9cd3fcccf ] Currently, only the first matched node will be handled. This leads to jtag switching broken for RK3576, as rk3576-sys-grf is found before rk3576-ioc-grf. Change the code to scan all the possible node to fix the problem.

soc: rockchip: grf: Add select correct PWM implementation on RK3368

2025-11-17T21:34:12+00:00

Similar to the RK3288, the RK3368 has two different implementations of the PWM block inside the SoC - the newer ones that we have a driver for and that is used on every SoC and a previous variant that was likely left as a fallback if the new one creates problems. The devicetree is already set up for the new variant, so make sure we actually use it - similar to the RK3288.

soc: rockchip: grf: Set pwm2/xin32k pad default to xin32k for rk3368

2025-10-21T09:19:53+00:00

PWM2 and xin32k share the same pad, but some peripheral need the xin32k clock to run properly, such as tsadc. I have observed that this pad is used as xin32k by default on some existing board [1], so it maybe more appropriate to set it to xin32k by default. I also tested it on another rk3368 based board [2], without this adjust, tsadc does not work properly.

soc: rockchip: grf: switch to FIELD_PREP_WM16_CONST macro

2025-09-02T23:59:37+00:00

The era of hand-rolled HIWORD_UPDATE macros is over, at least for those drivers that use constant masks. Switch the rockchip grf driver to the FIELD_PREP_WM16_CONST macro, which brings with it more error checking while still being able to be used in initializers. All HIWORD_UPDATE instances and its definition are removed from the driver, as the conversion here is obvious, and static_asserts were used during development to make sure the ones greater than one bit in width were really equivalent.

soc: Switch back to struct platform_driver::remove()

2024-11-01T16:08:57+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/soc to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. On the way do a few whitespace changes to make indention consistent.

soc: rockchip: grf: Add rk3576 default GRF values

2024-08-23T10:33:58+00:00

Set SW controlled i3c weak pull up and disable JTAG function on SDMMC IO. The i3c weak pull up is activated to let all gpio banks be controlled by the pinctrl driver. Disabling the JTAG function lets the SDMMC core use its full IO width.

soc: rockchip: grf: Set RK3128's vpu main clock

2024-08-23T09:52:53+00:00

RK3128 has a setting in GRF which selects whether the vpu attached iommu uses the AXI clock of the decoder (vdpu) or the encoder (vepu). The default is vepu but some part of the vendor firmware sets it to vdpu. In order to be independent on whether any of those vendor firmware blobs is used to boot the SoC reset "vpu main clock" setting to it's default value.
