Cover letter [PATCH 0/2] ASoC: NXP/Freescale: sort the reg_defaults tables
reg_defaults must be sorted by ascending register address, since regcache_lookup_reg() locates entries in it with bsearch(). When a table is not sorted, bsearch() cannot find the entries which follow a descending step, so regcache_reg_needs_sync() falls back to reporting that a sync is needed for them. Those registers are then written to the device on every regcache_sync() even when they were never touched.
See commit fd80df352ba1 ("regcache: Add support for sorting defaults arrays") for the same problem in a different context.
The series is based on broonie/for-linus (05eebef3c7b2).
Affected tables:
sgtl5000_reg_defaults 1 of 35 entries unreachable
fsl_easrc_reg_defaults 3 of 120 entries unreachable
