This patch is dependent on a change in v6.3-rc1. I've applied that patch now to fbdev git tree. Will drop it again in case it conflicts somewhere. Thanks! Helge

It is preferred to use typed property access functions (i.e. of_property_read_<type> functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.
