Subject: [PATCH] ARM: sun4i: dt: Add sun4i-a10-usb-vbus-reg dts include file
|
|
|
|
Almost all sun4i and sun7i boards have a gpio controlled vbus for usb1 and
|
|
usb2, using gpio pin PH6 and PH3 as in the reference design. This commit adds
|
|
an include file for this, avoiding the need to copy and paste the exact same
|
|
dts code to almost all sun4i and sun7i dts files.
|
