Hi Mark,
This Renesas R-Car Gen3 RPC SPI driver is based on Boris's new
spi-mem direct mapping read/write mode [1][2].
v4 patch is according to Sergei's comments including:
1) Drop soc_device_match()
2) Drop unused RPC registers
3) Use ilog2() instead of fls()
4) Patch read 6 bytes ID w/ one command.
5) Coding style and so on.
v3 patch is according to Marek and Geert's comments including:
1) soc_device_mach() to set up RPC_PHYCNT_STRTIM.
2) get_unaligned()
3) rpc-mode for rpi-spi-flash or rpc-hyperflash.
4) coding style and so on.
v2 patch including:
1) remove RPC clock enable/dis-able control,
2) patch run time PM,
3) add RPC module software reset,
4) add regmap,
5) other coding style and so on.
thanks for your review.
best regards,
Mason
