2234
- * - Driver: saved/restored by the driver
2235
- * - Punit : saved/restored by the Punit firmware
2236
- * - No, w/o marking: no need to save/restore, since the register is R/O or
2237
- *                    used internally by the HW in a way that doesn't depend
2238
- *                    keeping the content across a suspend/resume.
2239
- * - Debug : used for debugging
2240
- *
2241
- * We save/restore all registers marked with 'Driver', with the following
2242
- * exceptions:
2243
- * - Registers out of use, including also registers marked with 'Debug'.
2244
- *   These have no effect on the driver's operation, so we don't save/restore
2245
- *   them to reduce the overhead.
2246
- * - Registers that are fully setup by an initialization function called from
2247
- *   the resume path. For example many clock gating and RPS/RC6 registers.
2248
- * - Registers that provide the right functionality with their reset defaults.
2249
- *
2250
- * TODO: Except for registers that based on the above 3 criteria can be safely
2251
- * ignored, we save/restore all others, practically treating the HW context as
2252
- * a black-box for the driver. Further investigation is needed to reduce the
2253
- * saved/restored registers even further, by following the same 3 criteria.
