51 * - As soon as SW sees the DL NAC error, it should schedule the error handler
52 * - Error handler would sleep for 50ms to see if there are any fatal errors
54 * - If there are fatal errors then SW does normal error recovery.
55 * - If there are no fatal errors then SW sends the NOP command to device
57 * - If NOP command times out, SW does normal error recovery
58 * - If NOP command succeed, skip the error handling.
68 * 600us which may not be enough for reliable hibern8 exit hardware sequence
77 * (atleast for 500us) from UFS rails (especially from VCCQ rail).
78 * To avoid this situation, add 2ms delay before putting these UFS
90 * The max. value PA_SaveConfigTime is 250 (10us) but this is not enough for
94 * software delay will not help on this case so we need to increase
95 * PA_SaveConfigTime to >32us as per vendor recommendation.
106 * Some pre-3.1 UFS devices can support extended features by upgrading
113 * Some UFS devices require delay after VCC power rail is turned-off.
114 * Enable this quirk to introduce 5ms delays after VCC power-off during
