Subject: [PATCH] i2c: document the SDA hold time binding
Date: Mon, 11 Feb 2019 14:25:15 +0100 [thread overview]
Message-ID: <20190211132515.24163-1-wsa+renesas@sang-engineering.com> (raw)
The documentation was forgotten when the feature was added.
Fixes: 4717be73c284 ("i2c: core: Parse SDA hold time from firmware")
Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com>

To everyone on CC: I want to confirm here that you use the value really for
t(hd:sta) and not t(hd:dat). I'd be a little confused otherwise...
