This commit adds the touchscreens from Toradex so one can enable it. Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com> --- Changes in v3: - Fix commit title to "...imx6-apalis:..." Changes in v2: - Deleted touchrevolution downstream stuff - Use generic node name - Put a better comment in there arch/arm/boot/dts/imx6dl-colibri-eval-v3.dts | 31 +++++++++++++++++++ arch/arm/boot/dts/imx6q-apalis-eval.dts | 13 ++++++++ arch/arm/boot/dts/imx6q-apalis-ixora-v1.1.dts | 13 ++++++++ arch/arm/boot/dts/imx6q-apalis-ixora.dts | 13 ++++++++ 4 files changed, 70 insertions(+)
