Subject: [PATCH/RFT 0/6] i2c: recovery: fix GPIO usage for recovery
Message-ID: <20180713210920.3648-1-wsa+renesas@sang-engineering.com>
To: linux-arm-kernel@lists.infradead.org

I have sent the last patch of this series before, but then I realized I need to
convert all users of GPIO recovery before. I needed to make sure they all set
the SDA GPIO to output, this is what patches 3-5 are doing. Which is also good
for them because then they can send STOP at apropriate places when doing
recovery.

Then, I noticed that two drivers were not using the open drain mode for SCL
which seems like a bug to me. So, patches 1+2 address that. I'd think those two
are stable material.

Due to no hardware, I could only build test these patches. I'd be really
looking forward to comments or tests of these patches.

A branch can be found here:

Thanks,
