[PATCH v2 00/25] Add audio support for the Renesas RZ/G3S SoC

[PATCH v2 00/25] Add audio support for the Renesas RZ/G3S SoC

[Claudiu]

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

Hi,

Series enables the audio support for the Renesas RZ/G3S
SoC along with runtime PM and suspend to RAM.

Patches:
-    01/25 - add clock, reset and power domain support
- 02-04/25 - update versaclock3 clock generator driver to support the
             5L35023 hardware variant; versaclock3 provides clocks for
             the audio devices (SSIF, DA7212 codec)
-    05/25 - add pin control support for audio
- 06-20/25 - add SSIF support for the RZ/G3S SoC; fixes and cleanups
             were also included
- 21-25/25 - add device tree support

Merge strategy, if any:
- clock patches (01-04/25) can go through the Renesas tree
- pinctrl patch (05/25) can go though the Renesas tree
- audio patches (06-20/25) can go through the audio tree
- device tree patches (21-25/25) can go through the Renesas tree

Thank you,
Claudiu Beznea

Changes in v2:
- fixed typos pointed out in the review process
- dropped da7213 patches already applied
- dropped patch "ASoC: sh: rz-ssi: Use a proper bitmask for clear bits"
  as requested in the review process

[PATCH v2 02/25] clk: versaclock3: Prepare for the addition of 5L35023 device

[Claudiu]

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

The 5P35023 and 5L35035 Versa 3 clock generator variants are different but
the versaclock3 driver could be used with small adjustments. The features
that are implemented in driver and differs b/w variants are the PLL2 Fvco
and clock sel bit for SE2 clock. Adjust the driver to prepare for the
addition of 5L35023 device.

[PATCH v2 03/25] dt-bindings: clock: versaclock3: Document 5L35023 Versa3 clock generator

[Claudiu]

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

There are some differences b/w 5L35023 and 5P35023 Versa3 clock
generator variants but the same driver could be used with minimal
adjustments. The identified differences are PLL2 Fvco, the clock sel
bit for SE2 clock and different default values for some registers.

[PATCH v2 07/25] ASoC: sh: rz-ssi: Use only the proper amount of dividers

[Claudiu]

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

There is no need to populate the ckdv[] with invalid dividers as that
part will not be indexed anyway. The ssi->audio_mck/bclk_rate should
always be >= 0.

[PATCH v2 12/25] ASoC: sh: rz-ssi: Use readl_poll_timeout_atomic()

[Claudiu]

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

Use readl_poll_timeout_atomic() instead of hardcoding something similar.
While at it replace dev_info() with dev_warn_ratelimited() as the
rz_ssi_set_idle() can also be called from IRQ context and if the SSI
idle is not properly set this is at least a warning for user.

Use goto label names that specify their action. In this way we can have
a better understanding of what is the action associated with the label
by just reading the label name.

[PATCH v2 15/25] ASoC: sh: rz-ssi: Rely on the ASoC subsystem to runtime resume/suspend the SSI

[Claudiu]

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

The ASoC subsystem takes care of runtime resume/suspend the audio
devices when needed. Just enable the runtime PM on the SSI driver and
let the subsystem runtime resume/suspend it. While at it use directly
the devm_pm_runtime_enable().

[PATCH v2 16/25] ASoC: sh: rz-ssi: Enable runtime PM autosuspend support

[Claudiu]

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

Enable runtime PM autosuspend support. The chosen autosuspend delay is
zero for immediate autosuspend. In case there are users that need a
different autosuspend delay, it can be adjusted through sysfs.

[PATCH v2 18/25] ASoC: sh: rz-ssi: Issue software reset in hw_params API

[Claudiu]

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

The code initially issued software reset on SNDRV_PCM_TRIGGER_START
action only before starting the first stream. This can be easily moved to
hw_params() as the action is similar to setting the clocks. Moreover,
according to the hardware manual (Table 35.7 Bits Initialized by Software
Reset of the SSIFCR.SSIRST Bit) the software reset action acts also on the
clock dividers bits. Due to this issue the software reset in hw_params()
before configuring the clock dividers. This also simplifies the code in
trigger API.

[PATCH v2 19/25] ASoC: sh: rz-ssi: Add suspend to RAM support

[Claudiu]

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

The SSIF-2 IP is available on the Renesas RZ/G3S SoC. The Renesas RZ/G3S
SoC supports a power-saving mode where power to most of the SoC
components is turned off. Add suspend/resume support to the SSIF-2 driver
to support this power-saving mode.

On SNDRV_PCM_TRIGGER_SUSPEND trigger the SSI is stopped (the stream
user pointer is left untouched to avoid breaking user space and the dma
buffer pointer is set to zero), on SNDRV_PCM_TRIGGER_RESUME software reset
is issued for the SSIF-2 IP and the clocks are re-configured.

Playback/ Capture is introduced in that patch.

audio_clk1 node is in the RZ/G3S dtsi to keep the compilation happy.

For this board the audio clock1 for the SSI 3 is from <&versa3 2>.

If we fill in the audio_clk1 here it will be useless, there will be no
consumers for it and it is not available on board.

Thank you,

As per SSI IP needs external clks AUDIO_CLK1 and AUDIO_CLK2. 

AUDIO_CLK1 is provided by versa3 generator and
AUDIO_CLK2 is provided by Crystal.

Currently AUDIO_CLK2 it reports a frequency of 12288000 which is a multiple of 48kHz
whereas for AUDIO_CLK1, it reports a frequency of 0. By defining the node, it will report as the value as
11289600 which is a multiple of 44.1kHZ.

From the schematic we know that versa 3 is providing this clock and the audio_clk1 has
a frequency of "11289600".

Biju

Why? You mentioned above that "AUDIO_CLK1 is provided by versa3 generator".
It will report the frequency provided by the versa3 clock generator, isn't it?

> By defining the node, it will report as the value as
> 11289600 which is a multiple of 44.1kHZ.

Defining the node as you proposed have no meaning as it will be anyway
disabled (see the dtsi) and will appear nowhere as no driver will be probed
for it.

Defining it's frequency and enabling will have no meaning either for the
SSI3, as the SSI3 is connected to <&versa3 2> (as of the binding proposed
in this patch).

<&versa3 2> connected to AUDIO_CLK1 pin is configured at 11.2896MHz in this

Output from versa3 generator is connector to AUDIO_CLK1 pin that you described in
SoC dtsi node with the entries

+	audio_clk1: audio-clk1 {
+		compatible = "fixed-clock";
+		#clock-cells = <0>;
+		/* This value must be overridden by boards that provide it. */
+		clock-frequency = <0>;
+		status = "disabled";
+	};

This needs to be overridden by board dts, where versa3 is providing this clk.
Currently there is no relation between this SoC device node and versa3 clk output for audio clk1.

That is a clock node, placeholder in the DTSI, to make compilation happy.

Only if used, otherwise is an useless node.

I may be wrong or I many not understand what you are trying to say, but
isn't what this patch does? See this diff from this patch:

I agree it is an useless node, if there is no relation between versa 3 output and
audio_clk1 node.

The ssi3 definitions are OK. audio_clk2 node, we described crystal frequency of 12288000.
Other audio_clk1 node is useless node, even though versa3 is providing required clock
with 11289600.

I am not sure is this definition is required or not as I am not a DT expert??
