Convert bindings for NXP PN544 NFC driver to YAML syntax. Signed-off-by: David Heidelberg <david@ixit.cz> --- v2 - Krzysztof is a maintainer - pintctrl dropped - 4 space indent for example - nfc node name v3 - remove whole pinctrl .../bindings/net/nfc/nxp,pn544.yaml | 61 +++++++++++++++++++ .../devicetree/bindings/net/nfc/pn544.txt | 33 ---------- 2 files changed, 61 insertions(+), 33 deletions(-) create mode 100644 Documentation/devicetree/bindings/net/nfc/nxp,pn544.yaml delete mode 100644 Documentation/devicetree/bindings/net/nfc/pn544.txt
