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. The last patch should be applied after the patchset [1]: [1] https://lore.kernel.org/all/20221118011714.70877-1-hal.feng@starfivetech.com/ Changes since v1: - 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-rc5.
