Subject: [PATCH v8 1/5] gpu: ipu-v3: ipu-ic: Fix saturation bit offset in TPMEM
Date: Tue, 21 May 2019 18:03:13 -0700	[thread overview]
Message-ID: <20190522010317.23710-2-slongerbeam@gmail.com> (raw)
In-Reply-To: <20190522010317.23710-1-slongerbeam@gmail.com>

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.

Fixes: 1aa8ea0d2bd5d ("gpu: ipu-v3: Add Image Converter unit")
