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 = ,/* SD_CD_1 */
 ,/* SD_WP_1 */
 ,   /* SD_CLK_1 */
 ;   /* SD_CMD_1 */
};

pins_bidir {
pinmux = ,   /* SD_D1_1 */
 ,   /* SD_D0_1 */
 ,   /* SD_D3_1 */
 ;   /* SD_D2_1 */
bi-directional;
};
};


Thanks,
Chris

Hi Laurent,

Pardon for reviving this old thread. I've noticed a couple of things
which might want some attention.

Cannot find such a file in linux-next. Perhaps you meant
Documentation/devicetree/bindings/display/panel/display-timing.txt?

Documentation/devicetree/bindings/display/panel/panel.txt includes a
"rotation" property, which we might want to fold here.
