From a12c0efc7a3f433377add0fa1fd0ed4836cc595e Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Wed, 2 May 2012 15:47:12 -0600 Subject: ARM: tegra: harmony: init regulators, PCIe when booting from DT There currently aren't bindings for the Tegra PCIe controller. Work on this is in progress, but not yet complete. Manually initialize PCIe when booting from device tree, in order to bring DT support to the same feature level as board files, which will in turn allow board files to be deprecated. PCIe on Harmony requires various regulators to be registered and enabled before initializing the PCIe controller. Note that since the I2C controllers are instantiated from DT, we must use i2c_new_device() to register the PMU rather than i2c_register_board_info().
