Subject: [PATCH v1 0/2] Add driver support for ESWIN eic7700 SoC sdhci controller

From: Xuyang Dong <dongxuyang@...incomputing.com>

	Add support for the sdhci-emmc and sdhci-sdio functionality in the Linux
	kernel. The driver provides basic functionality of emmc and sdio for the eic7700
	series chips, which are part of the	Eswin SoC family.

	Features:
	 Implement support for the ESWIN eic7700 SoC sdhci-emmc controller and
	 sdhci-sdio controller. Integrate with the Linux sdhci subsystem for consistency and
	 scalability.

	Supported chips:
	 ESWIN eic7700 series SoC.

	Test:
	 Test this patch on the Sifive HiFive Premier P550 (which uses the EIC7700 SoC),
	 including emmc and sdio peripherals. Perform read, write and erase tests on emmc.
	 Read and write tests after mounting the file system. Verification of kernel support
	 for emmc device. So this verifies that sdhci driver patch is working properly.
