*	spi/bcm63xx-hsspi: add support for dual spi read/write	Jonas Gorski	2015-08-25	1	-4/+9
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Add support for dual read/writes on spi-bcm63xx-hsspi. This has been tested with a s25fl129p1 dual read capable spi flash, with a nice speed improvement: serial read: root@OpenWrt:/# time dd if=/dev/mtd4 of=/dev/null bs=8192 2032+0 records in 2032+0 records out real 0m 4.39s user 0m 0.00s sys 0m 1.55s dual read: root@OpenWrt:/# time dd if=/dev/mtd4 of=/dev/null bs=8192 2032+0 records in 2032+0 records out real 0m 3.09s user 0m 0.00s sys 0m 1.56s Signed-off-by: Jonas Gorski <jogo@openwrt.org> Signed-off-by: Mark Brown <broonie@kernel.org>

*	spi: bcm63xx-hsspi: checking for ERR_PTR instead of NULL	Dan Carpenter	2013-12-09	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \|	devm_request_and_ioremap() returns NULL on error, it doesn't return an ERR_PTR(). This patch fixes it by switching to devm_ioremap_resource() which is the prefered function anyway.

	Add a driver for the High Speed SPI controller found on newer BCM63XX SoCs. It does feature some new modes like 3-wire or dual spi, but neither of it is currently implemented. Signed-off-by: Jonas Gorski <jogo@openwrt.org> Signed-off-by: Mark Brown <broonie@linaro.org>
