1 * Marvell sdhci-pxa v2/v3 controller
3 This file documents differences between the core properties in mmc.txt
4 and the properties used by the sdhci-pxav2 and sdhci-pxav3 drivers.
7 - compatible: Should be "mrvl,pxav2-mmc", "mrvl,pxav3-mmc" or
8 "marvell,armada-380-sdhci".
10 * for "mrvl,pxav2-mmc" and "mrvl,pxav3-mmc", one register area for
12 * for "marvell,armada-380-sdhci", two register areas. The first one
13 for the SDHCI registers themselves, and the second one for the
14 AXI/Mbus bridge registers of the SDHCI unit.
15 - clocks: Array of clocks required for SDHCI; requires at least one for
17 - clock-names: Array of names corresponding to clocks property; shall be
18 "io" for I/O clock and "core" for optional core clock.
21 - mrvl,clk-delay-cycles: Specify a number of cycles to delay for tuning.
