Roger Quadros 705e3ce37b usb: dwc3: core: Fix system suspend on TI AM62 platforms ... Since commit 6d73572206 ("usb: dwc3: core: Prevent phy suspend during init"), system suspend is broken on AM62 TI platforms. Before that commit, both DWC3_GUSB3PIPECTL_SUSPHY and DWC3_GUSB2PHYCFG_SUSPHY bits (hence forth called 2 SUSPHY bits) were being set during core initialization and even during core re-initialization after a system suspend/resume. These bits are required to be set for system suspend/resume to work correctly on AM62 platforms. Since that commit, the 2 SUSPHY bits are not set for DEVICE/OTG mode if gadget driver is not loaded and started. For Host mode, the 2 SUSPHY bits are set before the first system suspend but get cleared at system resume during core re-init and are never set again. This patch resovles these two issues by ensuring the 2 SUSPHY bits are set before system suspend and restored to the original state during system resume.
