Hello, This is a patch series for initial sdhci support on NXP S32G2 platforms. In the previous work[1], only basic DTs and serial ports are supported for minimum hardware booting. Here we want to add a mmc-host node and add support in the sdhci-esdhc-imx driver so that S32G2 can also mount file system from SDCard but not just ramdisk. As the first step, we choose fixed clocks to fulfill the requirements the mmc host driver needs, and they will be replaced by ARM SCMI clock protocol (0x14) once the SCMI feature are added into S32G2 DT later. This patchset has been verified with NXP downstream firmware blobs [ver: bsp27/28/29/30], such as TF-A[2] and U-Boot[3] (BL33) on CodeAurora.
