[PATCH AUTOSEL 5.4 06/24] ASoC: rt5640: Fix dac- and adc- vol-tlv values being off by a factor of 10

[Sasha Levin]

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit cfa26ed1f9f885c2fd8f53ca492989d1e16d0199 ]

The adc_vol_tlv volume-control has a range from -17.625 dB to +30 dB,
not -176.25 dB to + 300 dB. This wrong scale is esp. a problem in userspace
apps which translate the dB scale to a linear scale. With the logarithmic
dB scale being of by a factor of 10 we loose all precision in the lower
area of the range when apps translate things to a linear scale.

E.g. the 0 dB default, which corresponds with a value of 47 of the
0 - 127 range for the control, would be shown as 0/100 in alsa-mixer.

Since the centi-dB values used in the TLV struct cannot represent the
0.375 dB step size used by these controls, change the TLV definition
for them to specify a min and max value instead of min + stepsize.

Note this mirrors commit 3f31f7d9b540 ("ASoC: rt5670: Fix dac- and adc-
vol-tlv values being off by a factor of 10") which made the exact same
change to the rt5670 codec driver.

[PATCH AUTOSEL 5.4 08/24] ASoC: sgtl5000: set DAP_AVC_CTRL register to correct default value on probe

[Sasha Levin]

From: Benjamin Rood <benjaminjrood@gmail.com>

[ Upstream commit f86f58e3594fb0ab1993d833d3b9a2496f3c928c ]

According to the SGTL5000 datasheet [1], the DAP_AVC_CTRL register has
the following bit field definitions:

| BITS  | FIELD       | RW | RESET | DEFINITION                        |
| 15    | RSVD        | RO | 0x0   | Reserved                          |
| 14    | RSVD        | RW | 0x1   | Reserved                          |
| 13:12 | MAX_GAIN    | RW | 0x1   | Max Gain of AVC in expander mode  |
| 11:10 | RSVD        | RO | 0x0   | Reserved                          |
| 9:8   | LBI_RESP    | RW | 0x1   | Integrator Response               |
| 7:6   | RSVD        | RO | 0x0   | Reserved                          |
| 5     | HARD_LMT_EN | RW | 0x0   | Enable hard limiter mode          |
| 4:1   | RSVD        | RO | 0x0   | Reserved                          |
| 0     | EN          | RW | 0x0   | Enable/Disable AVC                |

The original default value written to the DAP_AVC_CTRL register during
sgtl5000_i2c_probe() was 0x0510.  This would incorrectly write values to
bits 4 and 10, which are defined as RESERVED.  It would also not set
bits 12 and 14 to their correct RESET values of 0x1, and instead set
them to 0x0.  While the DAP_AVC module is effectively disabled because
the EN bit is 0, this default value is still writing invalid values to
registers that are marked as read-only and RESERVED as well as not
setting bits 12 and 14 to their correct default values as defined by the
datasheet.

The correct value that should be written to the DAP_AVC_CTRL register is
0x5100, which configures the register bits to the default values defined
by the datasheet, and prevents any writes to bits defined as
'read-only'.  Generally speaking, it is best practice to NOT attempt to
write values to registers/bits defined as RESERVED, as it generally
produces unwanted/undefined behavior, or errors.

Also, all credit for this patch should go to my colleague Dan MacDonald
<dmacdonald@curbellmedical.com> for finding this error in the first
place.

[PATCH AUTOSEL 5.4 09/24] ASoC: es8316: Simplify adc_pga_gain_tlv table

[Sasha Levin]

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit bb18c678754ce1514100fb4c0bf6113b5af36c48 ]

Most steps in this table are steps of 3dB (300 centi-dB), so we can
simplify the table.

This not only reduces the amount of space it takes inside the kernel,
this also makes alsa-lib's mixer code actually accept the table, where
as before this change alsa-lib saw the "ADC PGA Gain" control as a
control without a dB scale.

[PATCH AUTOSEL 5.4 10/24] ASoC: cs42l42: Fix Bitclock polarity inversion

From: Lucas Tanure <tanureal@opensource.cirrus.com>

[ Upstream commit e793c965519b8b7f2fea51a48398405e2a501729 ]

The driver was setting bit clock polarity opposite to intended polarity.
Also simplify the code by grouping ADC and DAC clock configurations into
a single field.

[PATCH AUTOSEL 5.4 13/24] ASoC: cs42l42: Always wait at least 3ms after reset

[Sasha Levin]

From: Lucas Tanure <tanureal@opensource.cirrus.com>

[ Upstream commit 19325cfea04446bc79b36bffd4978af15f46a00e ]

This delay is part of the power-up sequence defined in the datasheet.
A runtime_resume is a power-up so must also include the delay.

[PATCH AUTOSEL 5.4 21/24] ASoC: rt5659: Update MCLK rate in set_sysclk()

[Sasha Levin]

From: Sameer Pujar <spujar@nvidia.com>

[ Upstream commit dbf54a9534350d6aebbb34f5c1c606b81a4f35dd ]

Simple-card/audio-graph-card drivers do not handle MCLK clock when it
is specified in the codec device node. The expectation here is that,
the codec should actually own up the MCLK clock and do necessary setup
in the driver.
