Subject: [PATCH v2 4/5] ARM: dts: meson8m2: update the offset of the canvas module
Date: Mon, 20 May 2019 21:43:52 +0200
Message-ID: <20190520194353.24445-5-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20190520194353.24445-1-martin.blumenstingl@googlemail.com>

With the Meson8m2 SoC the canvas module was moved from offset 0x20
(Meson8) to offset 0x48 (same as on Meson8b). The offsets inside the
canvas module are identical.

Correct the offset so the driver uses the correct registers.
