From 0ba6deddaae74f0539c0303bfb5f860adbe1a68b Mon Sep 17 00:00:00 2001 From: Jernej Skrabec Date: Mon, 3 Aug 2026 18:10:50 +0200 Subject: [PATCH] drm/sun4i: hdmi-phy: Fix H6 8-bit MPLL config at 594 MHz The 8-bit entry of the last MPLL row (594 MHz) doesn't lock reliably on H6. 4K@60 RGB/YUV444, which is the mode that reaches this entry, doesn't come up. Align the value with the vendor driver. Other entries are left alone, they are used by lower pixel clocks which work fine. Tested with 4K@60 on a LG TV.
