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> --- I will merge this through the ARM SoC tree, just looking for ACKs from Andrew et al, maybe an indication from Dmitry if the RMI4 stuff will be merged so I can apply this too. --- arch/arm/boot/dts/ste-href-tvk1281618.dtsi | 37 +++++++++++++++++++++++++++++- 1 file changed, 36 insertions(+), 1 deletion(-) -- 2.4.3 -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
