[GIT PULL v2] ARM: at91: soc for 5.15

[<nicolas.ferre@microchip.com>]

From: Nicolas Ferre <nicolas.ferre@microchip.com>

Arnd, Olof,

Here are the soc changes for 5.15 which contains the introduction of our new
SoC family: the SAMA7G5.
Note that one header file is shared with the clock sub-system. We synchronized
with Stephen to make it appear in this Pull-Request.

- v1 -> v2: text of the signed tag aligned with kernel revision targeted.

Thanks, best regards,
  Nicolas

  ARM: at91: pm: add sama7g5 shdwc (2021-07-19 14:32:13 +0200)

----------------------------------------------------------------
AT91 soc for 5.15:

- add new SoC based on a Cortex-A7 core: the SAMA7G5 family
  - mach-at91 entry, Kconfig and header files
  - Power Management Controller (PMC) code and associated power management
    changes. Support for suspend/resume, Ultra Low Power modes and
    Backup with Memory in Self-Refresh mode.
  - Power management association with DDR controller and
    shutdown controller for addressing this variety of modes.
