^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6) Required properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) - compatible: "socionext,milbeaut-m10v-sdhci-3.0"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) - clocks: Must contain an entry for each entry in clock-names. It is a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) list of phandles and clock-specifier pairs.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) See ../clocks/clock-bindings.txt for details.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) - clock-names: Should contain the following two entries:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) "iface" - clock used for sdhci interface
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) "core" - core clock for sdhci controller
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) Optional properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) - fujitsu,cmd-dat-delay-select: boolean property indicating that this host
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) requires the CMD_DAT_DELAY control to be enabled.
