| Subject: drm/amd/display: Do not set optimized_require to false after plane |
| disable |
| |
| From: Sung Lee <sung.lee@amd.com> |
| |
| [ Upstream commit df36f6cf23ada812930afa8ee76681d4ad307c61 ] |
| |
| [WHY] |
| The optimized_require flag is needed to set watermarks and clocks lower |
| in certain conditions. This flag is set to true and then set to false |
| while programming front end in dcn20. |
| |
| [HOW] |
| Do not set the flag to false while disabling plane. |
