Subject: [PATCH 1/2] mv_ddr: ddr3: Use correct bitmask for read sample delay
Date: Wed, 27 May 2020 13:31:29 +1200 [thread overview]
Message-ID: <20200527013131.1663-2-judge.packham@gmail.com> (raw)
In-Reply-To: <20200527013131.1663-1-judge.packham@gmail.com>
From: Chris Packham <chris.packham@alliedtelesis.co.nz>
In the Armada 385 functional spec (MV-S109094-00 Rev. C) the read sample
delay fields are 5 bits wide. Use the correct bitmask of 0x1f when
extracting the value.
