From e6fd60c4aab55cfc1c128770848d8a0538c60781 Mon Sep 17 00:00:00 2001 From: Garrett Brown Date: Mon, 9 Sep 2024 21:02:24 -0700 Subject: [PATCH] linux: Enable CONFIG_I2C_BRCMSTB for proper HDMI I2C support This patch enables the CONFIG_I2C_BRCMSTB option in vc4graphics.cfg to ensure proper support for the `brcm,bcm2711-hdmi-i2c` device node. Without this configuration, the I2C bus associated with HDMI on Broadcom BCM2711-based systems may fail to probe, causing issues with HDMI communication and display initialization. Additionally, this resolves potential deferred probe issues observed in the kernel logs, ensuring the correct initialization of the HDMI I2C bus.
