This driver has been added instead of improving spi-bcm53xx. It has some advantages: allows SPI speed control & hopefully doesn't have bug that was stopping us from using multiple SPI messages for writing flash data. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

Subject: [PATCH] spi: brcmstb-qspi: Broadcom settop platform driver
|
|
|
|
Adding the settop SoC platfrom driver, this driver is compatible
|
|
with the settop MSPI+BSPI and MSPI only blocks implemented on the
|
|
SoCs. Driver calls the spi-bcm-qspi probe(), remove() and pm_ops.
