Subject: [PATCH 0/4] Add I2C controller support for MT6797 SoC
Date: Sat, 22 Feb 2020 21:54:40 +0530	[thread overview]
Message-ID: <20200222162444.11590-1-manivannan.sadhasivam@linaro.org> (raw)

Hello,

This patchset adds I2C controller support for Mediatek MT6797 SoC. There
are a total of 8 I2C controllers in this SoC (2 being shared) and they are
same as the controllers present in MT6577 SoC. Hence, the driver support is
added with DT fallback method.

As per the datasheet, there are controllers with _imm prefix like i2c2_imm
and i2c3_imm. These appears to be in different memory regions but sharing
the same pins with i2c2 and i2c3 respectively. Since there is no clear
evidence of what they really are, I've adapted the numbering/naming scheme
from the downstream code by Mediatek.

This patchset has been tested on 96Boards X20 development board.

Thanks,
Mani
