ARM: dts: at91: sama5d2: Add DMA bindings for the flx1 I2C function (1a6508a2) · Commits · 戴 / test

Spare boards of duplicating the DMA bindings. Describe the flx1 DMA bindings in the SoC dtsi. Users that don't want to use DMA for their flexcom functions have to overwrite the flexcom DMA bindings in their board device tree. Signed-off-by:
