The SD/MMC block on the RZ/G3E ("R9A09G047") SoC is similar to that
of the RZ/V2H, but the SD0 channel has only dedicated pins, so we must
use SD_STATUS register to control voltage and power enable (internal
regulator).
For SD1 and SD2 channel we can either use gpio regulator or internal
regulator (using SD_STATUS register) for voltage switching.
For SD0, fixed voltage(eMMC) uses fixed regulator and non-fixed voltage
(SD) uses internal regulator.
v1->v2:
* Collected tags.
* Documented internal regulator as optional property for both RZ/G3E and
RZ/V2H SoCs.
* Updated commit description for regulator used in SD0 fixed and
non-fixed voltage case in patch#3.
* As the node enabling of internal regulator is controlled through status,
added a check for device availability.
* Status of internal regulator is disabled in the SoC .dtsi. Override
the status in the board DTS when needed.
* Added support for enabling SDHI internal regulator in RZ/V2H
* Added missing header file gpio.h
* Used fixed regulator for eMMC on SD0 and dropped sd0-iovs pins for
eMMC.
* Sorted pinctrl nodes for sd2
* Enabled internal regulator for SD2.
* Added support for enabling SD on SDHI0
* Replaced the regulator usd_vdd_3p3v->reg_3p3v.
* Renamed the gpio-hog node sd1-pwr-en->sd1-pwr-en-hog.
* Sorted sd1 pin ctrl nodes.
