/**
* 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 sticker 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.
