This patch series add Atmel new SoC SAMA5D4 support, which embedded
the Cortex-A5 core.
This patch series also add the EK board base on SAMA5D4 SoC support.
Bo Shen (9):
ARM: at91: move pmc base address into soc header
ARM: atmel: sama5d3 is a family member of sama5
ARM: at91: clock: use cpu_has_pcr for pcr1 checking
nand: atmel: runtime to generate galois table
net: macb: using default value for FBLDO
mci: atmel: add new ip version 0x600 support
ARM: at91: add sama5d4 soc support #1
ARM: at91: add sama5d4 soc support #2
ARM: at91: add sama5d4ek board support

Yes, we can. However, I think use the GPIO i2c first, after the i2c fix has been applied, then switch to use atmel i2c driver. In this way, it won't block the sama5d4ek board support go into mainline. Btw, if the i2c fix has been applied before I send the v2 patch, I will switch to use atmel i2c driver.
