This series consists four patches. Patch 1 adds dai sequence support
for cml/jsl/tgl platforms which is different from the sequence on glk
platform. Patch 2 adds max98360a support to the maxim-common module.
Patch 3 adds driver data for jsl_cs4242_mx98360a which supports
cs42l42 and max98360a running on jsl boards. Patch 4 refactor the
sof_rt5682 to use the max98360 code in the maxim-common module.
Brent Lu (4):
ASoC: Intel: sof_cs42l42: support JSL DAI link sequence
ASoC: Intel: maxim-common: support max98360a
ASoC: intel: sof_cs42l42: add support for jsl_cs4242_mx98360a
ASoC: Intel: sof_rt5682: code refactor for max98360a

2.17.1
The backend DAI link sequence of GLK platform is different from the
sequence of other platforms. We refactor the sof_card_dai_links_create()
function to support both style.
GLK: SPK - HP - DMIC - HDMI
Other: HP - DMIC - HDMI - SPK

2.17.1
This patch adds driver data for jsl_cs4242_mx98360a which supports two
max98360a speaker amplifiers on SSP1 and cs42l42 headphone codec on
SSP0 running on JSL platform. DAI format is leveraged from sof_rt5682
machine driver to reuse the topology.
Also use module device table to replace module alias.

This also looks like we have two topologies configuring the same DAIs
differently on different platforms.
Why can't we pick one configuration that would work in all cases?

Humm, this looks like a missing dependency, I modified this a while ago.

I am really confused here.
The dailink sequence is whatever we want it to be. What matters is that
the dailink ID matches what is in the topology.
Is this saying that the GLK and JSL topologies did not follow any sort
of convention? Can you elaborate more on what is the issue?
Put differently, why can't we fix the topology instead with a reorder of
the dailinks?

snd_soc_find_dai_link() checked both dai link name and id when matching
topology and machine driver. Soundcard registration would fail if their id
doesn't match.
Cs42l42 is sharing topology with DA7219's topology source file sof-glk-da7219.m4
on GLK platform. The configuration is:
dai link id 0 is for spk
#SSP 1 (ID: 0) with 19.2 MHz mclk with MCLK_ID 1 (unused), 1.536 MHz blck
DAI_CONFIG(SSP, 1, 0, SSP1-Codec,
dai link id 1 is for headphone
#SSP 2 (ID: 1) with 19.2 MHz mclk with MCLK_ID 1, 1.92 MHz bclk
DAI_CONFIG(SSP, 2, 1, SSP2-Codec,
dai link id 2 is for dmic
DAI_CONFIG(DMIC, 0, 2, dmic01,
dai link id 3/4/5 is for hdmi
DAI_CONFIG(HDA, 3, 3, iDisp1,
DAI_CONFIG(HDA, 4, 4, iDisp2,
DAI_CONFIG(HDA, 5, 5, iDisp3,
When on JSL, we plan to share topology with rt5682 which has different dai link
sequence:
sof-jsl-rt5682.m4:
dai link id 0 is for headphone
DAI_CONFIG(SSP, 0, 0, SSP0-Codec,
dai link id 6 is for spk
# SSP 1 (ID: 6)
DAI_CONFIG(SSP, SPK_INDEX, 6, SPK_NAME,
SET_SSP_CONFIG)
dai link id 3/4/5 is for hdmi
# 4 HDMI/DP outputs (ID: 3,4,5)
DAI_CONFIG(HDA, 0, 3, iDisp1,
DAI_CONFIG(HDA, 1, 4, iDisp2,
DAI_CONFIG(HDA, 2, 5, iDisp3,
I'm not sure if there is convention about the sequence to follow?

The comment just say we are reusing rt5685's sof-jsl-rt5682-mx98360a.tplg.
This patch does not care about the dai sequence. Maybe I should reword the
commit log.

I was referring to the bclk frequency, one case uses 2.4 and the other
3.072MHz.

The 2.4MHz setting isn't ready when we enabled this codec so we selected
3.072MHz. Since we are updating topology for PLL issue soon, we can change
bclk frequency to 2.4MHz as well. How do you think?

The 3.072MHz clock will require the 24.576MHz PLL to be on on the
SOC/PCH. If you can use 2.4 MHz without any loss of quality and the
codec can deal with 25 bit slots with 24-bit data it's better power-wise.
We try to use 64.fs only when it's absolutely mandatory, e.g. if the
codec or amplifier doesn't support the 25/24 configuration. IIRC this
was the case with TI PCM512x and Maxim amps.
We've also used the 3.072 MHz bit clock when there are constraints on
the clock sources and selectors. This isn't the case on GLK but the SOF
commit 0a97c1a92f2d93bd4d45bc99d61e362cd214748c clarified the clock
selection for newer platforms, including JSL. In the end we may be
forced to use the 3.072 MHz PLL, you'd need to look at the various
topologies used with this machine driver.

ok, now I get what you are trying to do.
Unfortunately there are no conventions so far, and since we have to be
backwards-compatible with topology files already released we will need
to deal with the different configurations in this machine driver, you're
right about this.
The code you suggested is fine, but we can future-proof it a bit.
Instead of assuming any order depending on GLK or !GLK, we can add a BE
'base' for headphone, amp, DMIC and DMIC each (represented as a constant
structure) and point to different configurations depending on a quirk.
That way we can deal with other permutations such as HP - SPK - HDMI - DMIC
