From 05f13f5b5996d20a9819e0c6fd0cda4956c8aff9 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Wed, 17 Jun 2020 10:03:37 +0200 Subject: drm/ast: Remove unused code paths for AST 1180 The ast driver contains code paths for AST 1180 chips. The chip is not supported and the rsp code has never been tested. Simplify the driver by removing the AST 1180 code.
