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