Subject: [PATCH v3 0/3] Add USB2PHY Port Reset Control driver for Renesas RZ/V2H(P) SoC

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Hi All,

This patch series adds support for the USB2PHY Port Reset control driver
for the Renesas RZ/V2H(P) SoC. The changes include documenting the USB2PHY
Port Reset control bindings and adding the driver.

v2->v3
- Dropped Acks from Conor and Fabrizio, due to below changes
- Renamed binding renesas,rzv2h-usb2phy-ctrl.yaml to
  renesas,rzv2h-usb2phy-reset.yaml
- Renamed node name in example to reset-controller
- Renamed function names in reset-rzv2h-usb2phy.c
- Kept the reset line in asserted state during probe
- Added comment for rzv2h_init_vals[]
- Added entry in MAINTAINERS file

v1->v2
- Dropped binding postfix in subject line for patch 1/2
- Moved acquiring the ctrl2 pin in deassert callback
- Updated ctrl_status_bits

Cheers,
Prabhakar
