This adds the Synaptics RMI4 touchscreen to the Ux500 TVK user interface board. Tested on the U8500 HREFv60plus with the TVK UIB. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> --- ARM SoC maintainers: please apply this patch directly for-next on some DT branch, I have no other Ux500 DT patches. These bindings are ACKed by Rob Herring in another thread so I think it's pointless to keep it out of tree. --- arch/arm/boot/dts/ste-href-tvk1281618.dtsi | 37 +++++++++++++++++++++++++++++- 1 file changed, 36 insertions(+), 1 deletion(-) -- 2.4.3 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
