Subject: [PATCH v7 1/5] gpu: ipu-v3: ipu-ic: Fix saturation bit offset in TPMEM
Date:   Sat,  6 Apr 2019 16:08:59 -0700
Message-Id: <20190406230903.16488-2-slongerbeam@gmail.com>
In-Reply-To: <20190406230903.16488-1-slongerbeam@gmail.com>
References: <20190406230903.16488-1-slongerbeam@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The saturation bit was being set at bit 9 in the second 32-bit word
of the TPMEM CSC. This isn't correct, the saturation bit is bit 42,
which is bit 10 of the second word.
