This small patch series removes mt6577 support from the i2c-mt65xx driver and devicectree binding documentation. The existing i2c-mt65xx driver relies on DMA since it was first introduced. mt6577 does not support DMA [1] for I2C and SoC's Generic DMA engine cannot be used for this purpose, too, which makes this particular driver incompatible with mt6577 and other similar SoCs with same I2C IP.
