Subject: [PATCH v2] counter/ti-eqep: Fix regmap max_register
Date: Sun, 25 Oct 2020 11:51:22 -0500 [thread overview]
Message-ID: <20201025165122.607866-1-david@lechnology.com> (raw)
The values given were the offset of the register after the last
register instead of the actual last register in each range. Fix
by using the correct last register of each range.
Fixes: f213729f6796 ("counter: new TI eQEP driver")
Signed-off-by: David Lechner <david@lechnology.com>
Acked-by: William Breathitt Gray <vilhelm.gray@gmail.com>
