[PATCH v4 0/7] aspeed-g6: enable usb support

[rentao.bupt at gmail.com]

From: Tao Ren <rentao.bupt at gmail.com>

The patch series aims at enabling USB Host and Gadget support on AST2600
platforms.

Patch #1 includes vhub's usb descriptors in struct "ast_vhub": all usb
descriptor changes will go to the per-vhub instance instead of touching
the global default descriptors.

Patch #2 replaces hardcoded vhub port/endpoint number with device tree
properties, so that it's more convenient to add support for ast2600-vhub
which provides more downstream ports and endpoints.

Patch #3 enables ast2600 support in aspeed-vhub usb gadget driver.

Patch #4 adds USB devices and according pin groups in aspeed-g6 dtsi.

Patch #5 and #6 add vhub port/endpoint properties into aspeed-g4 and
aspeed-g5 dtsi.

Patch #7 adds device tree binding document for aspeed usb-vhub driver.
