This is necessary for a conforming userspace looking across all GPIO chips for the GPIO lines named "GPIO-A" thru "GPIO-L". Signed-off-by: Linus Walleij --- I don't have this hardware available, you can test it easily by compiling tools/gpio/* and issue "lsgpio" to see the GPIO line names in the console. Please apply this even if you're not applying the second patch renaming the DTS files. --- arch/arm64/boot/dts/qcom/apq8016-sbc.dts | 167 +++++++++++++++++++++++++++++++ 1 file changed, 167 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/apq8016-sbc.dts b/arch/arm64/boot/dts/qcom/apq8016-sbc.dts index 825f489a2af7..40b0d62861bb 100644 --- a/arch/arm64/boot/dts/qcom/apq8016-sbc.dts +++ b/arch/arm64/boot/dts/qcom/apq8016-sbc.dts @@ -19,3 +19,170 @@ model = "Qualcomm Technologies, Inc.
