rockchip: clk: clk_rk3576: Add support for RK3576 GMAC 25MHz clock output

2026-06-09T16:19:05Z

Rockchip RK3576 SoC has two built-in GMACs which connect to external PHYs via RGMII interface. The RGMII link can be clocked by either the PHY or the SoC. When the SoC is the master, as is the case on the RK3576 EVB1, the output clock needs to be configured in the CRU. Add the respective logic for getting and setting the RGMII reference clock output for both GMAC0 and GMAC1. Signed-off-by: Alexey Charkov Reviewed-by: Quentin Schulz Reviewed-by: Kever Yang

rockchip: spl: Add support for booting from UFS

2026-06-08T13:32:40Z

Add the required architecture-specific lookups to enable U-boot SPL to load images from UFS storage devices on Rockchip RK3576, which has a boot ROM capable of loading the SPL image from UFS. Reviewed-by: Jonas Karlman Signed-off-by: Alexey Charkov

rockchip: sdram: Add rockchip_sdram_type() helper

rockchip: spl: Add a read_brom_bootsource_id() helper

2025-11-02T18:14:09Z

The bootsource ids reported by BootROM of RK3528 and RK3576 for e.g. SPI NOR and USB differs slightly compared to prior SoCs: - Booting from sfc0 (ROCK 4D) report the normal bootsource id 0x3. - Booting from sfc1 M1 (NanoPi M5) report a new bootsource id 0x23. - Booting from sfc1 M0 has not been tested (no board using this config). - Booting from USB report a new bootsource id 0x81 on RK3528 and RK3576. Add a helper function to read the bootsource id. This helper function will be used to translate the new values to the common BROM_BOOTSOURCE enum values on RK3528 and RK3576.

rockchip: rk3288: grf: Unify speed/flowctrl fields for clarity

2025-05-08T03:48:13Z

Update GMAC speed and flow control fields in GRF_SOC_CON1 to use RK3288_GMAC_* prefix, ensuring a consistent naming convention. It also shifts each mask/bit definition to match the actual hardware bits, which makes future usage easier. Signed-off-by: Christoph Fritz Reviewed-by: Kever Yang

reset: rockchip: implement rk3576 lookup table

2025-04-23T14:12:05Z

The current DT bindings for the rk3576 clock use a different ID than the one that is supposed to be written to the hardware registers. Thus, we cannot use directly the id provided in the phandle, but rather use a lookup table to correctly setup the hardware. This follows the implementation done in the Linux-Kernel and also how the rk3588 does this both in the Linux-Kernel as well as U-Boot.
