Revert "mtd: atmel_nand: Support variable RB_EDGE interrupts"
This reverts commit 5ddc7bd43ccc ("mtd: atmel_nand: Support variable RB_EDGE interrupts") Because 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. It is a datasheet bug. Cc: <stable@vger.kernel.org> Fixes: commit 5ddc7bd43ccc ("mtd: atmel_nand: Support variable RB_EDGE interrupts") Signed-off-by: Wenyou Yang <wenyou.yang@atmel.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
