From fba6767c2dabcfaed0a8abf77fde0a8cb1b9fe10 Mon Sep 17 00:00:00 2001 From: Konrad Dybcio Date: Sat, 28 May 2022 18:03:50 +0200 Subject: [PATCH] drm/msm/a6xx: Add speedbin support for A619 GPU There are various SKUs of A619, ranging from 565 MHz to 850 MHz, depending on the bin. Add support for distinguishing them, so that proper frequency ranges can be applied, depending on the HW.
