Subject: [PATCH 1/2] ARM: dts: exynos4212-tab3: add samsung,invert-vclk flag to fimd
Date: Mon, 01 Jan 2024 22:00:15 +0100 [thread overview]
Message-ID: <20240101-tab3-display-fixes-v1-1-887ba4dbd16b@gmail.com> (raw)
In-Reply-To: <20240101-tab3-display-fixes-v1-0-887ba4dbd16b@gmail.com>
After more investigation, I've found that it's not the panel driver
config that needs to be modified to invert the data polarity, but
the FIMD config.
Add the missing invert-vclk option that is required to get the display
to work correctly.
