[PATCHv2 1/2] ARM: dts: imx53: PPD: Add fixed-regulator information

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add information about 3V3 power rail to avoid kernel warnings,
that dummy regulators have been added.

Signed-off-by: Sebastian Reichel <sebastian.reichel@xxxxxxxxxxxxxxx>

Changes since PATCHv1:
 * split usbphy rename into its own patch
 * drop useless regulator-boot-on
