4205 | * Workaround for errata i734 in DSS dispc | |
4206 | * - LCD1 Gamma Correction Is Not Working When GFX Pipe Is Disabled | |
4207 | * | |
4208 | * For gamma tables to work on LCD1 the GFX plane has to be used at | |
4209 | * least once after DSS HW has come out of reset. The workaround | |
4210 | * sets up a minimal LCD setup with GFX plane and waits for one | |
4211 | * vertical sync irq before disabling the setup and continuing with | |
4212 | * the context restore. The physical outputs are gated during the | |
4213 | * operation. This workaround requires that gamma table's LOADMODE | |
4214 | * is set to 0x2 in DISPC_CONTROL1 register. | |
4215 | * | |
4216 | * For details see: | |
4217 | * OMAP543x Multimedia Device Silicon Revision 2.0 Silicon Errata | |
