Subject: [PATCH 0/2] mtd: atmel_nand: remove compatible "atmel,sama5d4-nfc"

It is a datasheet bug, for current SoCs, the RB_EDGE3(i.e. bit 27)
of HSMC_SR register does not exist, the RB_EDGE0 (i.e. bit 24) is
the ready/busy line edge status bit. So the compatible
"atmel,sama5d4-nfc" is unneeded.


Wenyou Yang (2):
  Revert "mtd: atmel_nand: Support variable RB_EDGE interrupts"
  ARM: at91/dt: use "atmel,sama5d3-nfc" compatible for nfc
