2023-06-09mtd: rawnand: meson: waiting w/o wired ready/busy pinArseniy Krasnov
If there is no wired ready/busy pin, classic way to wait for command completion is to use function 'nand_soft_waitrdy()'. Meson NAND has special command which allows to wait for NAND_STATUS_READY bit without reading status in a software loop (as 'nand_soft_waitrdy()' does). To use it send this command along with NAND_CMD_STATUS, then wait for an interrupt, and after interrupt send NAND_CMD_READ0. So this feature allows to use interrupt driven waiting without wired ready/busy pin.

'commit 7499bfeedb47 ("mtd: rawnand: arasan: Update NAND bus clock instead of system clock")' and 'commit e16eceea863b ("mtd: rawnand: arasan: Fix clock rate in NV-DDR")' fixes the timeout issue in NVDDR mode with SW-ECC so, reverting the changes as this work around is no longer required.
