Subject[PATCH v5 0/3] Support for USB DRD Phy driver for NS2
Changes in v5:
Removed references to phy_ops in the same driver by connect_work
event handler to change the phy modes.

To support dynamically changing the mode of the phy, it does
not require doing a phy reset/programming of PHY PLL. Changes
are made to the connect_work routine to just program the required
register bits to achieve this purpose.

<clip: as before>
Changes in v4:
Remove references to edev->name in debug prints.

Changes in v3:
Remove unnecessary checks for poweron as suggested in review.

Changes in v2:
1. Initialize file operations .owner field with THIS_MODULE.
2. Remove unnecessary gpio example in DT bindings documentation.
This is previously acked by Rob Herring <>

Introduction for PATCH v1:

This patch adds support for USB Dual Role Device Phy for Broadcom
Northstar2 SoC. Apart from the new phy driver, this patchset contains
changes to Kconfig, Makefile, and Device tree files.

This patchset is tested on Broadcom NS2 BCM958712K reference board.

Branch: ns2_drdphy_v5
