During back-to-back speaker playback the PA sometimes fails to enable
because a few I2S/TDM and clock source registers retain their previous
state and are not reprogrammed on the next stream.
Reset the relevant I2S/TDM, clock source and bandgap override registers
in hw_free() so the codec is torn down cleanly and the speaker amplifier
comes up reliably on back-to-back use cases. Move the bandgap override
reset out of set_sysclk() into the teardown path where it belongs.

Maili ships its own firmware, so its topology file has to live in a
separate maili/ firmware directory. The topology load path is derived
from the sound card driver_name, so reusing the Hawi data would look
up the topology under hawi/ instead.
Add a dedicated maili_priv_data with driver_name "maili" for the
qcom,maili-sndcard compatible so the topology is loaded from the maili/
directory. It keeps the same DAPM widgets and enables codec sysclk,
MI2S BCLK and WCD jack detection for the Maili audio pipeline.

Add compatibles for the RX, TX and VA macro codecs found in the Low
Power Audio SubSystem (LPASS) of the Qualcomm Maili SoC.
The Maili RX, TX and VA macros are identical to their Hawi counterparts,
so document them with the corresponding Hawi compatible as fallback.

You miss hawi compatible used alone. At least on a next from a 18th.

Add the Low Power Audio SubSystem (LPASS) device tree infrastructure
for Hawi to describe the ADSP-based audio pipeline.
Add the GPR (Generic Packet Router) node with q6apm and q6prm audio
services, LPASS RX, TX and VA macro codecs, SoundWire controllers,
VA CSR clock provider, and LPI TLMM pinctrl node required by the audio
subsystem.

Wire up the audio use cases on the Hawi MTP board on top of the LPASS
nodes added to the SoC dtsi.
Add the sound card (qcom,hawi-sndcard) with the TDM playback, WCD
playback/capture and VA DMIC capture DAI links and the associated audio
routing. Describe the WCD9395 codec, enable the RX and TX SoundWire
controllers with their WCD RX/TX satellite ports, and add the WSA8855
speaker amplifier on i2c3. Configure the VA macro DMIC supply and the
required TLMM pin states (WCD reset, WSA IRQ, WSA shutdown).

Prasad Kumpatla
Add the Low Power Audio SubSystem (LPASS) device tree infrastructure
for Maili, mirroring the Hawi SoC, so the ADSP-based audio pipeline can
be described by boards.
This adds under the ADSP GLINK edge the GPR (Generic Packet Router)
node with the q6apm and q6prm services, and on the SoC bus the RX, TX
and VA Bolero macro codecs, their RX/TX SoundWire controllers, the VA
CSR heartbeat clock provider, and the LPASS LPI TLMM pinctrl node with
the DMIC, I2S and SoundWire pin states used by the audio blocks.
The SoundWire controllers are left status = "disabled" here; boards
enable them once the attached codecs are described.

Wire up the audio use cases on the Maili MTP board on top of the LPASS
nodes added to the SoC dtsi, mirroring the Maili QRD board.
Add the sound card with the TDM playback, WCD playback/capture and VA
DMIC capture DAI links and the associated audio routing. Describe the
WCD9395 codec, enable the RX and TX SoundWire controllers with their
WCD RX/TX satellite ports, and add the WSA8855 speaker amplifier on
i2c3. Configure the VA macro DMIC supply and the required TLMM pin
states (WCD reset, WSA IRQ, WSA shutdown).
The MTP and QRD boards share the same SoC and PMIC rails, so the same
regulators (vreg_l2d_1p8, vreg_l4g_1p2, vreg_l15b_1p8, vreg_bob1,
vreg_l1g_1p2, vreg_l10b_1p8) and the pmh0110_f_e0_gpios speaker
shutdown GPIO from the shared pmh0110-kaanapali.dtsi apply unchanged.

and Maili platforms to control all the LPI GPIOs.

As I have repeatedly told Qualcomm people please stop sending me patches
that don't apply, please collaborate with your colleagues to get
whatever it is you depend on merged and once that has happened send your
new stuff. Qualcomm is sending a very high volume of patches, they seem
to get limited review from other Qualcomm people and progress very
slowly. I'm getting a lot of Qualcomm code sent to me, in hard to
manage forms. Please also consider helping out with review of other
code, not just submitting your own. This is not directed to you
specifically, this is more Qualcomm as a whole.
I've dropped this for now, please resend once it can at least be
applied.
