From 24fec75017ae2c9ecc5db71feb999f73d57ba04f Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Thu, 11 Aug 2016 11:42:20 +0100 Subject: [PATCH] dmaengine: tegra210-adma: Update driver to use of_pm_clk_add_clk Commit 498b5fdd40dd ("PM / clk: Add support for adding a specific clock from device-tree") add a new helper function for adding a clock from device-tree to a device. Update the ADMA driver to use this new function to simplify the driver.
