1 Device Tree Bindings for the SDHCI Controllers present on TI's AM654 SOCs
3 The bindings follow the mmc[1], clock[2] and interrupt[3] bindings.
4 Only deviations are documented here.

11 - compatible: should be "ti,am654-sdhci-5.1"
12 - reg: Must be two entries.
13 - The first should be the sdhci register space
14 - The second should the subsystem/phy register space
15 - clocks: Handles to the clock inputs.
16 - clock-names: Tuple including "clk_xin" and "clk_ahb"
17 - interrupts: Interrupt specifiers
18 - ti,otap-del-sel: Output Tap Delay select
19 - ti,trm-icp: DLL trim select
20 - ti,driver-strength-ohm: driver strength in ohms.
21 Valid values are 33, 40, 50, 66 and 100 ohms.
