From 773df3f5e9fdda028ade319990d1b672ce68592f Mon Sep 17 00:00:00 2001 From: Sunny He Date: Thu, 22 Jun 2017 13:48:30 -0700 Subject: gpu: nvgpu: remove ltc_common.c Remove ltc_common.c and integrate the included functions into device specific ltc_gXXXX.c files. Merge non-device reg definition dependent ltc functions into ltc_gk20a.c/h. Prior to this patch, ltc_common.c was being directly included into the device specific ltc source files as a workaround to allow different devices to share the same code but still include in different hw reg definitions. Given that this approach was not adopted for other systems, this code has been separated out for readability and consistency.
