This adds support for the Microchip PIC32 platform along with the specific variant PIC32MZDA on a PIC32MZDA Starter Kit. Signed-off-by: Joshua Henderson <redacted> Cc: Ralf Baechle <redacted> Acked-by: Rob Herring <robh@kernel.org> --- Changes since v4: None Changes since v3: - Remove broken URL and use full manual name for boot protocol Changes since v2: None Changes since v1: None --- .../bindings/mips/pic32/microchip,pic32mzda.txt | 31 ++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 Documentation/devicetree/bindings/mips/pic32/microchip,pic32mzda.txt
