Subject: [PATCH 0/3] mmc: avoid vicious circle when retuning
Date: Thu, 24 Jun 2021 17:16:13 +0200	[thread overview]
Message-ID: <20210624151616.38770-1-wsa+renesas@sang-engineering.com> (raw)

See patch 1 for a description of the problem. This series implements the
alternative approach suggested by Adrian (thanks!). It also adds some
documentation and a minor cleanup which I came up with while working on
the fix. Patch 1 can go to stable as is, the rest built on top of that.

This series fixes the performance issue which we saw when injecting CRC
errors on Renesas R-Car Gen3 hardware.

Looking forward to comments!
