Subject: [PATCH 00/21] aspeed: Extend ast2600 I2C model with new mode
Date: Mon,  6 Jun 2022 17:07:11 +0200	[thread overview]
Message-ID: <20220606150732.2282041-1-clg@kaod.org> (raw)

Hello,

Here is a series aggregating recent changes proposed on the Aspeed
ast2600 I2C controller model. 

First comes a large set of changes converting the model to use the
registerfield interface and adding the I2C new register mode
(Joe). Since this is complex to review, extra tests are added to the
acceptance test suite to check that I2C devices are still functional
in the ast2600-evb machine. These tests use small buildroot images
available on GH. 

The ast1030 and ast2600 SoC share the same I2C logic. This series adds
I2C support to the ast1030 now that new register mode is supported.
There was a previous proposal from Troy doing the same but Joe's
patchset covers the same need (and converts the model to registerfield)

Follows a proposal from Klaus adding support for multi master in the
I2C core and the Aspeed I2C model, for the old register mode only. The
new register mode still needs to be addressed but this shouldn't take
too long once old register mode is merged.

Last, I have added the I2C echo device and test provided by Klaus. I
think it would be interesting to keep them for tests. Please, tell me.

Thanks,

C.
