+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
