ROCK Pi S is RK3308 based SBC from radxa.com. ROCK Pi S has a,
- 256MB/512MB DDR3 RAM
- SD, NAND flash (optional on board 1/2/4/8Gb)
- 100MB ethernet, PoE (optional)
- Onboard 802.11 b/g/n wifi + Bluetooth 4.0 Module
- USB2.0 Type-A HOST x1
- USB3.0 Type-C OTG x1
- 26-pin expansion header
- USB Type-C DC 5V Power Supply

This patch enables
- Console
- NAND Flash
- SD Card

I think this should be pwm-supply = <&vcc5v0_sys>

see:

drivers/regulator/pwm-regulator.c

static const struct regulator_desc pwm_regulator_desc = {
         .name           = "pwm-regulator",
         .type           = REGULATOR_VOLTAGE,
         .owner          = THIS_MODULE,
         .supply_name    = "pwm",
};

The mmc.txt didn't explicitly say disable-wp is for SD card slot only,
but that is what it was designed for in the first place.
Remove all disable-wp from emmc or sdio controllers.
