Subject: [PATCH 0/2] Add bus recovery to i2c-pxa
Date: Wed, 6 May 2020 10:40:01 +0100	[thread overview]
Message-ID: <20200506094001.GP1551@shell.armlinux.org.uk> (raw)

Hi,

This series adds bus recovery to i2c-pxa, using GPIOs to manually
recover the bus. This has been proven to work on Armada 3720 with
various SFP modules that appear to misbehave.

I am only expecting patch 1 to be applied to the i2c tree; patch 2
should be applied through normal routes via the arm-soc tree, but
are included in this series since it is part of the same change.
