spi: sh_qspi: Make use of the 32byte FIFO

2018-04-11T21:19:51Z

The QSPI controller on RCar Gen2 has 32byte FIFO. Instead of doing the SPI transmission 1 byte at time, if there is a 32byte chunk of data to be transferred, fill the FIFO completely and then transfer the data to/from the FIFO. This increases the SPI NOR access speed significantly. Signed-off-by: Marek Vasut Cc: Nobuhiro Iwamatsu

spi: sh_qspi: Replace ad hoc waiting with wait_for_bit

2018-04-11T21:19:51Z

Replace the ad-hoc endless loops with wait_for_bit() with reasonable timeout. Note that the loops had internal 10uS delays, although there is no reason for those on this HW, so they are dropped. Signed-off-by: Marek Vasut Cc: Nobuhiro Iwamatsu

spi: sh_qspi: Drop SPBDCR wait

2018-04-11T21:19:51Z

Waiting for SPBDCR == 1 is not required and is covered by the subsequent wait for SPSR_SPRFF, so drop this. Signed-off-by: Marek Vasut Cc: Nobuhiro Iwamatsu

spi: sh_qspi: Replace data types with short ones

2018-04-11T21:19:50Z

Just replace unsigned {char,short,long} with u{8,16,32}, no functional change. Signed-off-by: Marek Vasut Cc: Nobuhiro Iwamatsu

mtd: spi: Add Renesas RPC SPI-flash driver

2018-04-11T21:12:01Z

Add driver for the RPC block in SPI-flash mode. This driver allows access to a SPI NOR flash attached to the RPC block and does not support RPC in Hyperflash mode. Note that this block is extremely selective when communicating with the SPI NOR. Signed-off-by: Marek Vasut Cc: Nobuhiro Iwamatsu

Revert "spi: atmel: Drop non-dm code"

2018-04-07T13:19:00Z

As we aren't quite able to convert some platforms with a very small size limit in SPL yet, we need to revert this for now. This reverts commit 7b0947787358c6b277431d6b76ce043d8bec641d. Signed-off-by: Tom Rini

Revert "spi: atmel: Drop atmel_spi.h"

powercp: mpc8xx: move commproc.h

2018-04-06T20:30:37Z

include/commproc.h is dedicated to the 8xx, rename it cpm_8xx.h and move it into arch/powerpc/include/asm Signed-off-by: Christophe Leroy

powerpc: mpc8xx: Change CONFIG_8xx to CONFIG_MPC8xx

2018-04-06T20:30:37Z

CONFIG_8xx doesn't mean much outside of arch/powerpc/ This patch renames it CONFIG_MPC8xx just like CONFIG_MPC85xx etc ... It also renames 8xx_immap.h to immap_8xx.h to be consistent with other file names. Signed-off-by: Christophe Leroy

spi: atmel: default y if DM_SPI && ARCH_AT91

2018-04-06T20:11:09Z

ATMEL_SPI is now fully converted to driver-model and respective boards switch to DM_SPI as well, so make default y for ARCH_AT91 Signed-off-by: Jagan Teki Acked-by: Wenyou Yang
