Raw Blame History

From 6d80f39a376532c5d54fd72686534e2cd5d59652 Mon Sep 17 00:00:00 2001
From: Radoslav <radoslavv@centrum.sk>
Date: Sat, 15 Apr 2023 22:47:26 +0200
Subject: enable TV Output on OrangePi Zero LTE
Credits to sorce https://github.com/robertojguerra/orangepi-zero-full-setup/blob/main/README2.md
Merged:
1. sunxi-6.1/0036-wip-h3-h5-cvbs-armbian.patch : makes additions to the "dts", which tells the kernel where are the new devices. Adds kernel code to interact with the tv encoder. With my modifications, now it is applicable to Armbian (this patch came from the LibreElec github).
https://github.com/robertojguerra/orangepi-zero-full-setup/blob/main/sunxi-6.1/0036-wip-h3-h5-cvbs-armbian.patch
2. sunxi-6.1/zzzz2-tv.patch : by Armbian user "gleam2003", adds directives to make sure that the dtbo (device tree binary overlay) is compiled
https://github.com/robertojguerra/orangepi-zero-full-setup/blob/main/sunxi-6.1/zzzz2-tv.patch
3. sunxi-6.1/zzzz3-tv.patch : more additions to the "dts" and "dtsi" (like C include files), which I noticed were included in "yam" patch, but missing from the LibreElec patch
https://github.com/robertojguerra/orangepi-zero-full-setup/blob/main/sunxi-6.1/zzzz3-tv.patch
