phy: rockchip-pcie: switch to FIELD_PREP_WM16 macro

2025-09-22T19:52:44Z

The era of hand-rolled HIWORD_UPDATE macros is over, at least for those drivers that use constant masks. The Rockchip PCIe PHY driver, used on the RK3399, has its own definition of HIWORD_UPDATE. Remove it, and replace instances of it with hw_bitfield.h's FIELD_PREP_WM16. To achieve this, some mask defines are reshuffled, as FIELD_PREP_WM16 uses the mask as both the mask of bits to write and to derive the shift amount from in order to shift the value. In order to ensure that the mask is always a constant, the inst->index shift is performed after the FIELD_PREP_WM16, as this is a runtime value. >From this, we gain compile-time error checking, and in my humble opinion nicer code, as well as a single definition of this macro across the entire codebase to aid in code comprehension. Tested on a RK3399 ROCKPro64, where PCIe still works as expected when accessing an NVMe drive. Signed-off-by: Nicolas Frattaroli Reviewed-by: Heiko Stuebner Signed-off-by: Yury Norov (NVIDIA)

phy: rockchip: phy-rockchip-inno-csidphy: allow writes to grf register 0

2025-09-10T15:52:28Z

The driver for the Rockchip MIPI CSI-2 DPHY uses GRF register offset value 0 to sort out undefined registers. However, the RK3588 CSIDPHY GRF this offset is perfectly fine (in fact, register 0 is the only one in this register file). Introduce a boolean variable to indicate valid registers and allow writes to register 0.
