^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25)   - clock-frequency : specifies eSDHC base clock frequency.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) Optional properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28)   - sdhci,wp-inverted : specifies that eSDHC controller reports
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29)     inverted write-protect state; New devices should use the generic
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30)     "wp-inverted" property.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31)   - sdhci,1-bit-only : specifies that a controller can only handle
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32)     1-bit data transfers. New devices should use the generic
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33)     "bus-width = <1>" property.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34)   - sdhci,auto-cmd12: specifies that a controller can only handle auto
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35)     CMD12.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36)   - voltage-ranges : two cells are required, first cell specifies minimum
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37)     slot voltage (mV), second cell specifies maximum slot voltage (mV).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38)     Several ranges could be specified.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39)   - little-endian : If the host controller is little-endian mode, specify
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40)     this property. The default endian mode is big-endian.
