From b8efd9d04537d6129e2ce8b067417e46b0e7436f Mon Sep 17 00:00:00 2001 From: Terje Bergstrom Date: Thu, 27 Jul 2017 12:58:03 -0700 Subject: gpu: nvgpu: Make LTC disabling common code Refactor the sync_debugfs LTC HAL op so that the logic to enable or disable LTC goes to common code nvgpu_ltc_sync_enabled() and the LTC HAL set_enabled only performs the hardware register access. Create a new common function nvgpu_init_ltc_support() to initialize the LTC software variable, and move hardware initialization of LTC to be called from it.
