Subject: [PATCH v2] drm/msm/adreno: Add support for Adreno 505 GPU

From: Daniil Titov <[email protected]>

This GPU is found on SoCs such as MSM8937 (450 MHz), MSM8940 (475 MHz),
SDM439 (650 MHz).

Changes in v2:
- use DRM_MSM_INACTIVE_PERIOD instead of 250 ms.
- Link to v1: https://lore.kernel.org/r/[email protected]
