Claudiu Beznea a02875c4cb ARM: at91: pm: fix self-refresh for sama7g5 ... It has been discovered that on some parts, from time to time, self-refresh procedure doesn't work as expected. Debugging and investigating it proved that disabling AC DLL introduce glitches in RAM controllers which leads to unexpected behavior. This is confirmed as a hardware bug. DLL bypass disables 3 DLLs: 2 DX DLLs and AC DLL. Thus, keep only DX DLLs disabled. This introduce 6mA extra current consumption on VDDCORE when switching to any ULP mode or standby mode but the self-refresh procedure still works.
