| Subject: gpu: ipu-v3: ipu-ic: Fix saturation bit offset in TPMEM |
| |
| From: Steve Longerbeam <slongerbeam@gmail.com> |
| |
| commit 3d1f62c686acdedf5ed9642b763f3808d6a47d1e upstream. |
| |
| 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") |
