From 1d92e1854c19c06c553243d29170bb4d1a9e3863 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/2] wayland: Switch to custom timer tick
The OE LVGL is configured to obtain timer tick from system timer
instead of using ad-hoc mechanisms to emulate timer tick using
threads or such. Use system timer to provide the tick.
The tick handling implementation comes from:
https://github.com/lvgl/lv_port_linux_frame_buffer.git
as of commit adf2c4490e17a1b9ec1902cc412a24b3b8235c8e
Upstream-Status: Inappropriate [Upstream repo is archived]
