I just tested this driver on the RZ/A1 RSK board.
The following worked good.
SCIF2, I2C, SDHI, Ethernet
SDHI also has bi-direction pins. For your reference, here was my DT:
/* SHDI ch1 on CN1 */
sdhi1_pins: sdhi1 {
pins {
pinmux = <RZA1_PINMUX(3, 8, 7)>, /* SD_CD_1 */
<RZA1_PINMUX(3, 9, 7)>, /* SD_WP_1 */
<RZA1_PINMUX(3, 12, 7)>, /* SD_CLK_1 */
<RZA1_PINMUX(3, 13, 7)>; /* SD_CMD_1 */
};
pins_bidir {
pinmux = <RZA1_PINMUX(3, 10, 7)>, /* SD_D1_1 */
<RZA1_PINMUX(3, 11, 7)>, /* SD_D0_1 */
<RZA1_PINMUX(3, 14, 7)>, /* SD_D3_1 */
<RZA1_PINMUX(3, 15, 7)>; /* SD_D2_1 */
bi-directional;
};
};
Thanks,
Chris
