mfd: twl: Convert to use maple tree register cache

broonie · lag-linaro · commit 1c943dfd8007 · 2023-11-01T10:02:15.000Z
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.
