Subject: [PATCH 2/3] ASoC: cs35l45: sort the register default table
Date: Wed, 5 Aug 2026 11:24:12 +0300 [thread overview]
Message-ID: <20260805082413.26174-3-peter.ujfalusi@linux.intel.com> (raw)
In-Reply-To: <20260805082413.26174-1-peter.ujfalusi@linux.intel.com>
reg_defaults must be sorted by ascending register address, as
regcache_lookup_reg() locates entries in it with bsearch(). See commit
fd80df352ba1 ("regcache: Add support for sorting defaults arrays").
cs35l45_defaults[] lists the DSP1_RX*_RATE and DSP1_TX*_RATE registers
(0x02b80080 - 0x02b802b8) in the middle of the table, ahead of entries with
much lower addresses, so the binary search does not find 36 of its 73
entries. regcache_reg_needs_sync() then cannot compare those against their
default and reports that a sync is needed, so they are written to the
device on every regcache_sync() even when they were never touched.
Sort the table by register address.
