Setting of phy mode to device/host is removed from phy power on. routine. Changes in v6: ============= Removed spin locks which are not required as the references to phy_ops in the same driver were removed in v5. Removed host/device 'notify' routines which are registered using 'extcon_register_notifier'. The irq handler is sufficient to deal with the change in extcon events within the same driver. 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. 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.
