Subject: [PATCH] ARM: sunxi: dt: Add sunxi-common-regulators include file
|
||
|
|
|
||
|
|
Most sunxi boards with a sata connector also have a gpio controlled connector
|
||
|
|
for sata target power and almost all sunxi boards have a gpio controlled vbus
|
||
|
|
for usb1 and usb2.
|
||
|
|
|
||
|
|
This commit adds an include file for the regulators representing these
|
||
|
|
supplies, avoiding the need to copy and paste the regulator code to allmost
|
||
|
|
all sunxi board dts files.
