1117 | * - Debug : used for debugging | |
1118 | * | |
1119 | * We save/restore all registers marked with 'Driver', with the following | |
1120 | * exceptions: | |
1121 | * - Registers out of use, including also registers marked with 'Debug'. | |
1122 | * These have no effect on the driver's operation, so we don't save/restore | |
1123 | * them to reduce the overhead. | |
1124 | * - Registers that are fully setup by an initialization function called from | |
1125 | * the resume path. For example many clock gating and RPS/RC6 registers. | |
1126 | * - Registers that provide the right functionality with their reset defaults. | |
1127 | * | |
1128 | * TODO: Except for registers that based on the above 3 criteria can be safely | |
1129 | * ignored, we save/restore all others, practically treating the HW context as | |
