1162 | * keeping the content across a suspend/resume. | |
1163 | * - Debug : used for debugging | |
1164 | * | |
1165 | * We save/restore all registers marked with 'Driver', with the following | |
1166 | * exceptions: | |
1167 | * - Registers out of use, including also registers marked with 'Debug'. | |
1168 | * These have no effect on the driver's operation, so we don't save/restore | |
1169 | * them to reduce the overhead. | |
1170 | * - Registers that are fully setup by an initialization function called from | |
1171 | * the resume path. For example many clock gating and RPS/RC6 registers. | |
1172 | * - Registers that provide the right functionality with their reset defaults. | |
1173 | * | |
1174 | * TODO: Except for registers that based on the above 3 criteria can be safely | |
1175 | * ignored, we save/restore all others, practically treating the HW context as | |
1176 | * a black-box for the driver. Further investigation is needed to reduce the | |
