2017-08-14	spi: rockchip: add compatible string for rv1108 spi	Andy Yan	1	-0/+1
	The spi on rv1108 is the same as other rockchip based socs, add compatible string for it. Signed-off-by: Andy Yan <andy.yan@rock-chips.com> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-12-19	spi: rockchip: support "sleep" pin configuration	Brian Norris	1	-0/+7
	In the pattern of many other devices, support a system-sleep pin configuration. Signed-off-by: Brian Norris <briannorris@chromium.org> Reviewed-by: Douglas Anderson <dianders@chromium.org> Tested-by: Caesar Wang <wxt@rock-chips.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-05-31	spi/rockchip: add rk3036/rk3228/rk3368 SoCs for spi document	Caesar Wang	1	-4/+7
	We had supported the rk3036/rk3066/rk3188/rk3228/rk3288/rk3368/rk3399 family SoCs in linux kernel. Let's add the other SoCs, in order to a better understanding from the rockchip spi document. Signed-off-by: Caesar Wang <wxt@rock-chips.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-02-18	spi: rockchip: add bindings for rk3399 spi	Xu Jianqun	1	-0/+1
	Add devicetree bindings for Rockchip rk3399 spi which found on Rockchip rk3399 SoCs. Signed-off-by: Jianqun Xu <jay.xu@rock-chips.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-03-26	spi/rockchip: Add device tree property to configure Rx Sample Delay	Julius Werner	1	-0/+4
	We have found that we can sometimes see read failures on boards with high-capacitance SPI lines. It seems that the controller samples the Rx data line too early, and its register interface has an "Rx Sample Delay" setting to fine-tune against this issue. This patch adds a new optional device tree entry that can configure this delay in terms of nanoseconds. The kernel will calculate the best-fitting amount of parent clock ticks to program the controller with based on that.

2014-09-04	spi/rockchip: Mark DMA as optional	Doug Anderson	1	-2/+6
	The Rockchip SPI controller works fine without DMA (aside from a few warnings). The DMA property even implies this, saying: DMA request names should include "tx" and "rx" if present. Officially mark the properties as optional. Signed-off-by: Doug Anderson <dianders@chromium.org> Signed-off-by: Mark Brown <broonie@kernel.org>
