From 93e1f2ad3042e41c96031191f2bb6db2d0011e9c Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Mon, 25 Oct 2021 17:29:01 +0200 Subject: [PATCH 005/828] drm/vc4: hdmi: Raise the maximum clock rate Now that we have the infrastructure in place, we can raise the maximum pixel rate we can reach for HDMI0 on the BCM2711. HDMI1 is left untouched since its pixelvalve has a smaller FIFO and would need a clock faster than what we can provide to support the same modes.
