From 19955c3d7453757271d05859958ca1804a5d2d67 Mon Sep 17 00:00:00 2001 From: "Manjunathappa, Prakash" Date: Wed, 19 Jun 2013 14:45:38 +0530 Subject: [PATCH] ARM: davinci: uart: move to devid based clk_get For modules having single clock, clk_get should be done with dev_id. But current davinci implementation handles multiple instances of the UART devices with single platform_device_register. Hence clk_get is based on con_id rather than dev_id, this is not correct. Do platform_device_register for each instance and clk_get on dev_id.
