Add new compatible and update driver to support Synopsys Advanced I2C
Controller (DWC_i2c [0]) present on TI TDA54 SoC. This is needed since
this controller differs from the existing designware i2c (DW_apb_i2c
[1]) in its register offsets and some register definitions.
The new compatible updates driver logic due to changes in register
definitions:
I'm working with a SoC with what looks to be another instance of this
new version of the DesignWare I2C controller - I saw your discussion
with Andy and the conclusion that a separate driver would be good. I'm
really keen to help out with getting the support for these IPs upstream
however I can, not sure what your plans/thoughts are there?
The I2C needs of the systems I'm using are fairly basic so I should only
need a small subset of the capabilities that'll be visible in your
systems, the only thing I can think might not come up for you is that my
systems are servers so will be using ACPI rather than DT.
I am planning to send next version in a few days... aligned with Andy's
suggestion for a separate driver. Would like to get your reviews once I do?
Let me know if you had something else in mind.
Thanks,
Aniket
