| * 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. |
