I wanted to add support for ti,lp5562, and found an old submission from Doug. While trying to modify that to work in current U-Boot, I found a problem with the "move label handling to core" patches.
Patch 1 is an attempt at (quick-)fixing that, though the real fix is probably to not bind the same driver to the top node as to the child nodes and using uc_plat->label to distinguish in .probe. Patch 2 touches the same area, and is needed for the lp5562 driver to work with existing DT bindings. Patch 3 introduces a helper which should allow removing some boilerplate in most individual drivers, and 4,5 apply that in the gpio and pwm drivers. Converting remaining drivers is trivial, but left out for now. Finally patch 6 is the reworked lp5562 driver. While I've changed it to match existing DT bindings (with the goal of making it work with our .dts that is known to work with the linux driver), most of the logic is unchanged from Doug's original patch, so he is still listed as author.
