Hi, This series of patches changes the tuning implementation, from the previous way of reading and writing system controller registers to reading and writing UHS_REG_EXT register, thus optimizing the tuning of obtaining delay-chain. Changes v2->v3: - Rebased to v6.6rc2. - Dropped redundant criteria. - Keeped "starfive,sysreg" in dts file. Changes v1->v2: - Rebased to v6.6rc1. - Keeped "starfive,sysreg" in dt-bindings but removed from required. - Changed the function interface name. - Maked the code implementation more concise. The patch series is based on v6.6rc2.
