Subsystem:
arm/cortina systems gemini arm architecture, open firmware and flattened device tree bindings, real time clock (rtc) subsystem, the rest · Maintainers:
Hans Ulli Kroll, Linus Walleij, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Alexandre Belloni, Linus Torvalds
Converts rtc/faraday,ftrtc01.txt to yaml. This permits to detect some missing properties: reg, resets, interrupts Signed-off-by: Corentin Labbe <clabbe@baylibre.com> --- .../bindings/rtc/faraday,ftrtc010.txt | 28 --------- .../bindings/rtc/faraday,ftrtc010.yaml | 59 +++++++++++++++++++ 2 files changed, 59 insertions(+), 28 deletions(-) delete mode 100644 Documentation/devicetree/bindings/rtc/faraday,ftrtc010.txt create mode 100644 Documentation/devicetree/bindings/rtc/faraday,ftrtc010.yaml
