+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

The dialog-lvgl has been unmaintained and stuck at LVGL v8.1.0 in its now archived repository branch main. There is subsequent effort in next/main branch which updates the code base to LVGL v8.2.0 that is almost compatible enough to still build against LVGL v8.3.7. Upgrade to this next/main branch which contains three additional commits on top of the main branch, which implement the update to newer LVGL. Add two more fixes to build against system timer provided tick and another fix for WL callback data type. Since there is no upstream, track the patches here for now.
