[PATCH 0/4] clk: qcom: Add LPASS clock/reset controllers for Glymur

[PATCH 0/4] clk: qcom: Add LPASS clock/reset controllers for Glymur

[Srinivas Kandagatla]

Add DT bindings and clock-controller drivers for the two LPASS reset
providers on the Glymur SoC:

  - qcom,glymur-lpassaudiocc  (LPASS Audio CC CSR): RX + WSA1..WSA4
    SoundWire CGCR resets
  - qcom,glymur-lpasscc       (LPASS CC CSR):       TX SoundWire CGCR
    reset

Only resets are exposed for now; the Q6DSP owns LPASS clocks via the
Q6PRM service on the GPR rpmsg channel, matching the existing SC8280XP
pattern (commits a5c9c3ba243a, c2ef1ec97c1f).

The reset providers are required by the LPASS audio macros and the
SoundWire controller to come out of reset on Glymur.

[PATCH 1/4] dt-bindings: clock: Add LPASS AUDIOCC and reset controller for Glymur

[Srinivas Kandagatla]

The LPASS (Low Power Audio Subsystem) Audio clock controller provides reset
support when it is under the control of Q6DSP.

Add support for those resets and adds IDs for clients to request the reset.

Binding looks exactly the same as qcom,sc8280xp-lpasscc.yaml. Just add
the compatible to the enum there, no need for a new file. Less code to
maintain, less possible mistakes.

Separate header file for clock IDs is fine, though.

Best regards,
Krzysztof

Yes, I was thinking of doing the same.

No need for a new example. Just add both compatibles to the existing
file for other compute platforms.

[PATCH 3/4] clk: qcom: Add lpass audio clock controller driver for Glymur

[Srinivas Kandagatla]

Add support for the lpass audio clock controller found on Glymur based
devices. This would allow lpass peripheral loader drivers to control the
clocks and bring the subsystems out of reset.

Currently this patch only supports resets as the Q6DSP is in control of
LPASS IP which manages most of the clocks via Q6PRM service on GPR rpmsg
channel.

Please don't use <linux/mod_devicetable.h>. That pulls in many unneeded
dependencies and I'm working on getting rid of it.

Just rely on <linux/platform_device.h> to provide of_device_id
(preferred), or include <linux/device-id/of.h> if you want to go full
iwyu.

Best regards
Uwe

[PATCH 4/4] clk: qcom: Add lpass clock controller driver for Glymur

[Srinivas Kandagatla]

Add support for the lpass clock controller found on Glymur based devices.
This would allow lpass peripheral loader drivers to control the clocks and
bring the subsystems out of reset.

Currently this patch only supports resets as the Q6DSP is in control of
LPASS IP which manages most of the clocks via Q6PRM service on GPR rpmsg
channel.
