[PATCH 00/11] ARM: at91: fixes and enhancement

[Claudiu Beznea]

Hi,

The following series adds:
- one fix for self-refresh on SAMA7G5 (patch 1/11)
- thermal management support for SAMA7G5 (patches 2/11-9/11)
- 2 cleanup patches (patches 10/11, 11/11)

Thank you,
Claudiu Beznea

Do not soft reset AC DLL as controller is buggy and this operation my
introduce glitches in the controller leading to undefined behavior.
