Subject: [PATCH 0/2] i2c: mediatek: remove mt6577 support
Date: Thu, 20 Jan 2022 21:58:51 +0300 [thread overview]
Message-ID: <20220120185853.24266-1-arzamas-16@mail.ee> (raw)
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.
