[PATCH 00/18] mfd: convert to use maple tree register cache

[Bo Liu]

The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache.

[PATCH 04/18] mfd: axp20x: convert to use maple tree register cache

[Bo Liu]

The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache.

[PATCH 08/18] mfd: khadas-mcu: convert to use maple tree register cache

[Bo Liu]

The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache.

[PATCH 10/18] mfd: wolfson: convert to use maple tree register cache

[Bo Liu]

The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache.

[PATCH 14/18] mfd: rsmu_i2c: convert to use maple tree register cache

[Bo Liu]

The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache.

If all of this is true, is there any reason to keep REGCACHE_RBTREE
around?  If not, perhaps REGCACHE_RBTREE should be treated as
REGCACHE_MAPLE in the regmap core code first, followed by a single
tree-wide patch to replace REGCACHE_RBTREE?

The change looks good, but whilst it won't cause any problems, it
seems a bit weird not to convert wm8997, wm8998 and cs47l24.
These are part of the same driver as wm5102 and wm5110.

There is a very small niche for devices where cache syncs are a
particularly important part of the workload where rbtree's choices might
give better performance, especially on systems with low end CPUs.

The REGCACHE_* value is specified by the device, not by the CPU?
While some of these MFD devices are on-SoC, and thus there is some
relation between device and CPU, several others (e.g. PMICs) are
external, and thus might be present on systems with a variety of CPU
performance.

Perhaps the value should depend on some CPU heuristic instead?

The device is going to dominate here, the main thing is how much of the

No.
