From 0106b6c114cf8b77d801d9e280b221f8b4d5595b Mon Sep 17 00:00:00 2001 From: AngeloGioacchino Del Regno Date: Thu, 3 Jul 2025 14:08:46 +0200 Subject: [PATCH] dt-bindings: PCI: mediatek-gen3: Add support for MT6991/MT8196 Add compatible strings for MT8196 and MT6991 (which are fully compatible between each other) and clock definitions. These new SoCs don't have tl_96m and tl_32k clocks, but need an AHB to APB bus clock and a low power clock.
