linux-toradex.git/drivers/mfd/wm831x-core.c, branch v6.15 Linux kernel for Apalis and Colibri modules mfd: Explicitly include correct DT includes 2023-08-18T20:48:03+00:00 Rob Herring robh@kernel.org 2023-07-14T17:47:27+00:00 dc0c386e09a701e3c7c2dd58799cee992fa4e4b6 The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

mfd: wm831x: Use maple tree register cache 2023-06-15T08:19:36+00:00 Mark Brown broonie@kernel.org 2023-04-25T18:03:33+00:00 7ef47a12a62e8fcf1b66a401cd6f3fc055581da0 regmap has introduced a maple tree based register cache which makes use of this more advanced data structure which has been added to the kernel recently. Maple trees are much flatter than rbtrees, meaning that they do not grow to such depths when the register map is sparse which makes access a bit more efficient. The maple tree cache type is still a bit of a work in progress but should be effective for some devices already. The wm831x devices have a pretty sparse register map and being always on devices never do cache syncs so don't hit the major current disadvantage so they should be good candiates for using the maple tree cache. Update to do so, there should be little if any visible difference at runtime.
