From 91390d857f6302f9c2923ec4188ea7e24ee537a2 Mon Sep 17 00:00:00 2001 From: Terje Bergstrom Date: Thu, 9 Aug 2018 09:20:33 -0700 Subject: gpu: nvgpu: Move therm HAL to common Move implementation of therm HAL to common/therm. ELCG and BLCG code was embedded in gr HAL, so moved that code to therm. Bump gk20a code to gm20b.
