Hi,
Series adds initial USB support for the Renesas RZ/G3S SoC.
Series is split as follows:
- patches 01-05/15 - add SYSC driver support; this is necessary for USB
PHY as the USB PHY driver need to touch a register in
the SYSC address space, in the initialization phase
- patch 06/15 - updates the USBHS documentation for RZ/G3S
- patches 07-10/15 - updates the USB PHY support to handle the SYSC
USB PWRRDY signal. Along with it a fix for the
DT bindings and one for the PHY driver were
added; fixes are RZ/G3S USB related
- patch 11/15 - document the USB PHY Ctrl support
- patches 12-15/15 - add device tree support
Merge strategy, if any:
- patches 01-05/15,12-14/15 can go through Renesas tree
- patch 06/14 can go though USB tree
- patches 07-10/14 can go through PHY tree
- patch 11/15 can go though reset controller tree
Thank you,
Claudiu Beznea
Changes in v2:
- dropped v1 patches already applied
- added fixes patches (07/14 and 09/14)
- dropped the approach of handling the USB PWRRDY though a reset controller
driver and introduced the signal concept for the SYSC driver; because
of this, most of the work done in v1 was dropped
- per patch changes are listed in individual patches, if any
