From b1ad4444ae92156e21972ce74eaafb82e0ac61d7 Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Tue, 13 Feb 2024 15:33:37 +0000 Subject: [PATCH 0894/1085] arm: dt: bcm2712: Reduce DDC frequency to 97.5kHz from 200kHz. The I2C spec says the DDC link should run at 100kHz or less, however Pi5/BCM2712 had been configured for 200kHz. Reduce it to comply with the spec, and match Pi4.
