Subject: [PATCH 00/16] Add initial USB support for the Renesas RZ/G3S SoC

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

Hi,

Series adds initial USB support for the Renesas RZ/G3S SoC.

Series is split as follows:

- patch 01/16		- add clock reset and power domain support for USB
- patch 02-04/16	- add reset control support for a USB signal
			  that need to be controlled before/after
			  the power to USB area is turned on/off.
			  
			  Philipp, Ulf, Geert, all,
			  
			  I detailed my approach for this in patch
			  04/16, please have a look and let me know
			  your input.
			  
			  Thank you!

- patch 05/16		- moves SoC identification to SYSC driver
- patch 06-08/16	- updates USB PHY control driver for USB
			  support
- patch 09/16		- update documentation for USBHS
- patch 10-12/16	- updates the USB PHY driver for USB support
- patch 13-15/16	- updates the device tree with USB support
- patch 16/16		- enables the reset control driver

Thank you,
Claudiu Beznea
