These are -user-visible using tools/gpio/lsgpio.c - -v2: Major rewrite by anholt: Flatten each GPIO line to a line in the - file for better diffing, prefix all expansion header pins with - "P<number>" or "P5HEADER_P<number>" and drop the mostly-unused - GPIO_GEN<smallnumber> names in favor of GPIO<socgpionumber>, fix - extra '[]' on a couple of lines, fix locations of SD_CARD_DETECT, - CAM_GPIO and STATUS_LED, fix HDMI_HPD polarities, rewrite A+ using - unreleased schematics. - -v3: More changes by anholt: Drop P<number> / P5HEADER<number> - prefixes. I had been skeptical about adding them, and was - convinced to drop them by Gottfried (who probably has more - experience with GPIOs in educational contexts than the rest of - us). Also drop [] brackets for "is pinmuxed", which didn't seem - to clarify, and were ambiguous for things like the SPI_*-labeled - pins which may or may not actually be pinmuxed to SPI. - -v4: Rename B+'s SDA0/SCL0 to match the other boards, despite the - naming on its schematic. - -Signed-off-by: Linus Walleij <linus.walleij@linaro.org> -Signed-off-by: Eric Anholt <eric@anholt.net> ---- - arch/arm/boot/dts/bcm2835-rpi-a-plus.dts | 65 +++++++++++++++++++++++++++++++ - arch/arm/boot/dts/bcm2835-rpi-a.dts | 67 ++++++++++++++++++++++++++++++++ - arch/arm/boot/dts/bcm2835-rpi-b-plus.dts | 66 +++++++++++++++++++++++++++++++ - arch/arm/boot/dts/bcm2835-rpi-b-rev2.dts | 66 +++++++++++++++++++++++++++++++ - arch/arm/boot/dts/bcm2835-rpi-b.dts | 67 ++++++++++++++++++++++++++++++++ - 5 files changed, 331 insertions(+) - ---- a/arch/arm/boot/dts/bcm2835-rpi-a-plus.dts -+++ b/arch/arm/boot/dts/bcm2835-rpi-a-plus.dts -@@ -22,6 +22,71 @@ - };
