Subject: [PATCH v2 0/3] StarFive's SDIO/eMMC driver support

Hi,

This patchset adds initial rudimentary support for the StarFive
designware mobile storage host controller driver. 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 <linux/gpio.h>'.
- 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.

  riscv: dts: starfive: Add mmc node
