Cc: Linus Walleij Cc: Bartosz Golaszewski Cc: linux-gpio@vger.kernel.org Signed-off-by: Rob Herring --- This warns on a few platforms missing clocks, interrupt-controller and/or #interrupt-cells. We could not make those required, but really they should be IMO. OTOH, it's platforms like Spear and Calxeda which aren't too active, so I don't know that we want to fix them. .../devicetree/bindings/gpio/pl061-gpio.txt | 10 --- .../devicetree/bindings/gpio/pl061-gpio.yaml | 69 +++++++++++++++++++ 2 files changed, 69 insertions(+), 10 deletions(-) delete mode 100644 Documentation/devicetree/bindings/gpio/pl061-gpio.txt create mode 100644 Documentation/devicetree/bindings/gpio/pl061-gpio.yaml diff --git a/Documentation/devicetree/bindings/gpio/pl061-gpio.txt b/Documentation/devicetree/bindings/gpio/pl061-gpio.txt deleted file mode 100644 index 89058d375b7c..000000000000 --- a/Documentation/devicetree/bindings/gpio/pl061-gpio.txt +++ /dev/null @@ -1,10 +0,0 @@ -ARM PL061 GPIO controller - -Required properties: -- compatible : "arm,pl061", "arm,primecell" -- #gpio-cells : Should be two.
