Subject: [PATCH 05/90] power: regulator: Add a driver for the AXP USB power
|
|
supply
|
|
|
|
This driver reports the presence/absence of voltage on the PMIC's USB
|
|
VBUS pin. This information is used by the USB PHY driver. The
|
|
corresponding Linux driver uses the power supply class, which does not
|
|
exist in U-Boot. UCLASS_REGULATOR seems to be the closest match.
