Hi,
The series adds reset controller support for SAMA7G5 SoCs. Compared with
previous version the reset controller embedded on SAMA7G5 is able to
reset individual on SoC devices (e.g. USB PHY controllers).
Among with this I took the change and converted reset controller
bindings to YAML (patch 2/8) and adapt reset controller nodes in
device tree files to comply with DT specifications (patch 1/8).
Thank you,
Claudiu Beznea
Changes in v3:
- use spin_lock_irqsave()/spin_unlock_irqrestore() and lock only
on update path

- in patch 4/10 added "SAMA7G5_" in front of macros to cope with file
naming and used (GPL-2.0-only OR BSD-2-Clause)
- in patch 6/10 documented the structure's members
- in patch 7/10:
- protect access to reset->dev_base with spin lock
- check for valid values of reset_spec->args[0] in
