From 42e52616f382a455d64629b156685d5adc21ce85 Mon Sep 17 00:00:00 2001 From: "H. Nikolaus Schaller" Date: Wed, 11 Sep 2019 19:47:11 +0200 Subject: cpufreq: ti-cpufreq: omap36xx use "cpu0","vbb" if run in multi_regulator mode In preparation for using the multi_regulator capability of this driver for handling the ABB LDO for OPP1G of the omap36xx we have to take care that the (legacy) vdd-supply name is cpu0-supply = <&vcc>; To do this we add another field to the SoC description table which optionally can specify a list of regulator names. For omap36xx we define "cpu0-supply" and "vbb-supply". The default remains "vdd-supply" and "vbb-supply". Signed-off-by: H.
