Peter Ujfalusi <peter.ujfalusi@linux.intel.com> says:
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 fd80df352b ("regcache: Add support for sorting defaults arrays")
for the same problem in a different context.
The series is based on broonie/for-linus (05eebef3c7).
Affected tables:
sgtl5000_reg_defaults 1 of 35 entries unreachable
fsl_easrc_reg_defaults 3 of 120 entries unreachable

reg_defaults must be sorted by ascending register address, as
regcache_lookup_reg() locates entries in it with bsearch(). See commit
fd80df352b ("regcache: Add support for sorting defaults arrays").
The four REG_EASRC_RRL() entries are listed as a block before the four
REG_EASRC_RRH() ones, but the two registers of a context alternate in
the address map (RRL(n) at 0x110 + 8 * n, RRH(n) at 0x114 + 8 * n).
This leaves REG_EASRC_RRL(1), REG_EASRC_RRL(2) and REG_EASRC_RRL(3)
unreachable. regcache_reg_needs_sync() then cannot compare them 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.

Peter Ujfalusi <peter.ujfalusi@linux.intel.com> says:
The reg_defaults array of a regmap_config must be sorted by ascending
register address: regcache_lookup_reg() finds entries in it with
bsearch(), and regcache_init() only kmemdup_array()s the array, it never
sorts it. See commit fd80df352b ("regcache: Add support for sorting
defaults arrays").
When the array is not sorted, bsearch() descends into the wrong half and
a number of entries can never be found. regcache_reg_needs_sync() then
cannot compare the cached value against the default and always reports
that a sync is needed, so those registers are written to the device on
every regcache_sync() even if they were never touched.
I found this while chasing a SoundWire NAK on an unimplemented register
and audited the reg_defaults tables in sound/ by replaying lib/bsearch.c
over each of them. These are the affected TI/Burr-Brown codecs:
pcm512x_reg_defaults 45 entries, 24 unreachable
tas675x_reg_defaults 69 entries, 14 unreachable
tas2552_reg_defs 21 entries, 7 unreachable
tas2764_reg_defaults 11 entries, 1 unreachable
tas2780_reg_defaults 10 entries, 1 unreachable
The patches only reorder the existing entries. The text of every entry
is kept verbatim, no default value is changed, and each resulting table
was verified to be fully reachable.
tas2783-sdw was fixed separately, it had already been posted.

These tables have entries which are out of order, so the binary search does
not find part of them. For those registers regcache_reg_needs_sync()
cannot compare the cached value against the 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.
On a RT712-VA this is not silent: the MIC_ARRAY function does not exist on
that part, so the extra writes are NAKed by the codec and the bus driver
reports
soundwire_intel.link.0: Msg ignored for Slave 6 (for addr: 0x8e00)
for every resume. For the other tables the extra writes are accepted and
only cost bus bandwidth on every runtime resume.
The sorting patches only reorder the existing entries, the text of every
entry is kept verbatim and no default value is changed. Each table was
verified by evaluating the register addresses and replaying lib/bsearch.c
on them.

Charles Keepax <ckeepax@opensource.cirrus.com> says:
This series reworks the SDCA HID code, the primary goals being to no
longer store runtime HID data in the DisCo data structures and remove
the need to pass the soundwire device into the ACPI parsing code.
To achieve this the HID device registration is moved to the IRQ work
flow rather than the ACPI work flow.
Also a few small issues are fixed up along the way, some formatting,
some missing cleanup/docs.

Rather than passing the SoundWire slave into find_sdca_filesets(),
stash the swift table whilst processing sdca_dev_register(). This
allows us to completely remove the passing of the sdw_slave into

The HID descriptors are defined at the function level in DisCo
and as such it makes more sense to parse and store them at
that level in the SDCA code. This shouldn't really make much
practical difference but is conceptually better and avoids
passing the function node down to the entity parsing code.
