From 3f2f689559f77a47972dede0483b7b8f2ead2125 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Tue, 7 Mar 2023 17:30:34 +0100 Subject: [PATCH] thermal/drivers/rcar_gen3_thermal: Remove R-Car H3 ES1.* handling MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit R-Car H3 ES1.* was only available to an internal development group and needed a lot of quirks and workarounds. These become a maintenance burden now, so our development group decided to remove upstream support and disable booting for this SoC. Public users only have ES2 onwards.
