Subject: [PATCH] ASoC: cs35l41: Update to use maple tree register cache
Git-commit: 78138627acc014dc3a23cb6f29f53a025544743f
Patch-mainline: v6.6-rc1
References: jsc#PED-6045 jsc#PED-6036 jsc#PED-6104 jsc#PED-6114 jsc#PED-6067 jsc#PED-6123
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. In
v6.5 it has also acquired the ability to generate multi-register writes in
sync operations, bringing performance up to parity with the rbtree cache
there.
Update the cs35l41 driver to use the more modern data structure.
