First we have the bootloader that may present something on the panel - next step it then the kernel. Bootloaders such as U-boot and barebox supports devicetree. So with the timings specified in the devicetree there are three users that can use the timings, and it is simple to share the timing specifications. As it is now one has to patch the kernel to add a panel to panel-simple, and add timing to device tree to let barebox use it. So it would be good once and for all to have the rules specified. And the preferred solution is to have timing in the devicetree so we can use it both in the kernel and in the bootloaders. Sam
