Cadhu have multiple power rails which are controlled by GPIOs. Add support of these power rail control through fixed regulators. Add entry for all fixed regulators for cardhu-a02 and a04. The details are taken from downstream kernel. Some points on this change are: * Add the tps65910-LDO5 entry and make it always ON to supply power to SDMMC. Once the sd driver support regulator handling, this flag will be remove. * Dropping registration of rail vdd_sdmmc1 as the gpio is used by sdhci power-gpio. This need to fix in sdhci driver and then need to add the registration mechanism. Just removing power-gpio and adding fixed regulator with this gpio is causing the sd access to fail because first probe call of this regulator fails due to non-available of parent and so it calls gpio_free() which disable the pins in gpio mode make pin output to LOW causes power to OFF. In probe retry, it got success and it powered-on but it again need to do again numeration of card here.

/**
|
|
* This file contains common DT entry for all fab version of Cardhu.
|
|
* There is multiple fab version of Cardhu starting from A01 to A07.
|
|
* Cardhu fab version A01 and A03 are not supported. Cardhu fab version
|
|
* A02 will have different sets of GPIOs for fixed regulator compare to
|
|
* Cardhu fab version A04. The Cardhu fab version A05, A06, A07 are
|
|
* compatible with fab version A04. Based on Cardhu fab version, the
|
|
* related dts file need to be chosen like for Cardhu fab version A02,
|
|
* use tegra30-cardhu-a02.dts, Cardhu fab version A04 and later, use
|
|
* tegra30-cardhu-a04.dts.
|
|
* The identification of board is done in two ways, by looking the sticker
|
|
* on PCB and by reading board id eeprom.
|
|
* The stciker will have number like 600-81291-1000-002 C.3. In this 4th
|
|
* number is the fab version like here it is 002 and hence fab version A02.
|
|
* The (downstream internal) U-Boot of Cardhu display the board-id as
|
|
* follows:
|
|
* BoardID: 0C5B, SKU: 0A01, Fab: 02, Rev: 45.00
|
|
* In this Fab version is 02 i.e. A02.
|
|
* The BoardID I2C eeprom is interfaced through i2c5 (pwr_i2c address 0x56).
|
|
* The location 0x8 of this eeprom contains the Fab version. It is 1 byte
|
|
* wide.
