There are 4 SD/MMC controller present in this SoC but only 2 are enabled currently for Bubblegum96 board to access uSD and onboard eMMC. SDIO support for this driver is not currently implemented. Note: Currently, driver uses 2 completion mechanisms for maintaining the coherency between SDC and DMA interrupts and I know that it is not efficient. Hence, I'd like to hear any suggestions for reimplementing the logic if anyone has. With this driver, this patchset also fixes one clk driver issue and enables the Actions Semi platform in ARM64 defconfig.
