From 42dc30231ba35939213c33378c17cb81c31b0a37 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Mon, 24 Jun 2013 12:50:16 +0200 Subject: regulator: max8973: initial DT support This patch adds primitive DT support to the max8973 regulator driver. None of the configuration parameters, supported in the platform data are yet available in DT, therefore no configuration is performed if booting with no platform data. This means, that DT instantiation can only be used on boards, where no run-time configuration of the chip is required. In such cases the driver can be used to scale its output voltage. In the future support for configuration parameters should be added.
