[PATCH v2 0/2] Add USB DRD 3.0 device node for Exynos7

[PATCH v2 0/2] Add USB DRD 3.0 device node for Exynos7

[Pankaj Dubey]

This patch series adds USB 3.0 DRD device node for Exynos7 and 
required Vbus and Vbus-boost support for espresso dev boards.
These patches are part of patch series [1] earlier submitted by Vivek

[1]: https://lkml.org/lkml/2014/11/21/247

While other patches in these series got merged, DTS related change were
left. I have prepared and tested these patches on top of krzk/for-next.

Changes since v1:
 - Updated S-o-B order and Authorship of patches.
 - Added Javier's Reviewed-by.
 - Replaced GPIO polarity values with appropriate macros.

dtc should complain here - you need:
	dwc3@15400000
In the same time I think the address node does not have to be put after
parent's usb.

I think these are the same as in Exynos5422, so EXYNOS5420_PIN_DRV_LV1

No, it didn't complain. Anyway, I will update as it's already taken care

Yes, but as it's not taken care in existing dts for other pin
definitions, so a Javier mentioned, this can be taken care as a separate
patch for all pin definitions? Or do you want me to first add patch
converting all these with macros and then on top of add this usb related
pin definitions.

It only complains if you run dtc with warnings enabled, i.e: make W=1
exynos7-espresso.dtb

It only complains if you run dtc with warnings enabled, i.e: make W=1

For new code let's use the macros even if entire file is not converted
(yet). The same like mixture of values and GPIO_ACTIVE_* macros. If
