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 a prerequisite for the ti,lp5562 driver, which turned out to be needed by Christian as well.
Patch 2 is an attempt at (quick-)fixing the mentioned "move label handling to core" problem. The real fix consists of changing remaining drivers to not bind the same driver to the top node as to the child nodes, but I can't test those other drivers.
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.
Changes in v2: Interchange order of patches 1 and 2, add a few R-bs, and try to trim down the commit message in patch 2.
