And this driver will be used in StarFive's VisionFive 2 board. The main purpose of adding this driver is to accommodate the ultra-high speed mode of eMMC. Changes v4->v5: - Added a incremental updates to fix a bug that prev_err is uninitialized. - Dropped the merged patches. - Dropped the dts patch. - Sorted compatible alphabetically in yaml. Changes v3->v4: - Added documentation to describe StarFive System Controller Registers. - Added aon_syscon and stg_syscon node. - Fixed some checkpatch errors/warnings. Changes v2->v3: - Wraped commit message according to Linux coding style. - Rephrased the description of the patches. - Changed the description of syscon regsiter. - Dropped redundant properties. Changes v1->v2: - Renamed the dt-binding 'starfive,jh7110-sdio.yaml' to 'starfive,jh7110-mmc.yaml'. - Changed the type of 'starfive,syscon' and modify its description. - Deleted unused head files like '#include '. - Added comment for the 'rise_point' and 'fall_point'. - Changed the API 'num_caps' to 'common_caps'. - Changed the node name 'sys_syscon' to 'syscon'. - Changed the node name 'sdio' to 'mmc'. The patch series is based on v6.1.
