[PATCH v3 0/5] ARM: OMAP: DTS/HWMOD/defconfig changes for USB3

[PATCH v3 0/5] ARM: OMAP: DTS/HWMOD/defconfig changes for USB3

[Kishon Vijay Abraham I]

From: Felipe Balbi <balbi@ti.com>

With these patches (plus a few others on the driver side which
will be going upstream soon) I could get functional USB3 with my
omap5-uevm platform.

Changes since v2:
	- added dt properties for enabling vbus/id interrupts and fixed
vbus-supply value after SMPS10 is modeled as 2 regulators

Changes since v1:
	- split ocp2scp dts and hwmod data into separate patches
	- reorganize the series in order to group DTS, hwmod and defconfig
	  changes

Benoit Cousson (1):
  arm: omap5: hwmod: add missing ocp2scp hwmod data

Felipe Balbi (4):
  arm: omap5: dts: fix reg property size
  arm: omap5: dts: fix ocp2scp DTS data
  arm: omap5: dts: add palmas-usb node
  arm: omap2plus_defconfig: enable dwc3 and dependencies

[PATCH v3 1/5] arm: omap5: dts: fix reg property size

[Kishon Vijay Abraham I]

From: Felipe Balbi <balbi@ti.com>

USB3 block has a 64KiB space, another 64KiB is
used for the wrapper.

Without this change, resource_size() will get
confused and driver won't probe because size
will be negative.

[PATCH v3 3/5] arm: omap5: dts: add palmas-usb node

[Kishon Vijay Abraham I]

From: Felipe Balbi <balbi@ti.com>

Without this node, there will be no palmas
driver to notify dwc3 that a cable has
been connected and, without that, dwc3
will never initialize.

[PATCH v3 5/5] arm: omap2plus_defconfig: enable dwc3 and dependencies

[Kishon Vijay Abraham I]

From: Felipe Balbi <balbi@ti.com>

DWC3 enables USB3 functionality for OMAP5 boards,
it's safe to enable those drivers in omap2plus_defconfig.

Excellent, thanks for that super quick update. I've just applied it and 
will try to push it ASAP.
I've just slightly changed the subjects to have both ARM and OMAP in 
capital letters for consistency.

Tony,

I will update my pull-request now before Kevin and Olof pulled it.

Regards,
Benoit
