Subject: [PATCH v2 0/2] Add USB2PHY control support 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 control on the Renesas
RZ/V2H(P) SoC. The changes include documenting the USB2PHY control
bindings and adding the USB2PHY control driver.

These changes are necessary to support the USB2.0 on the RZ/V2H(P) SoC.

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

Cheers,
Prabhakar
