Sometime will hang if you set the i2s pinctrl as the none setting.
Let's set the pinctrl as the default setting to enable the gpio up/down.

Support the rt5616 codec for kylin board, but we need
enable the i2s firstly.
Also, this patch adds the CPU/CODEC information for simple card
to make the happy work.

The sysclk seems be incorrect since we use the simple card for kylin
board.
The simple card call:
asoc_simple_card_probe ->
asoc_simple_card_dai_link_of ->
asoc_simple_card_sub_parse_of ->
...
clk = of_clk_get(args.np, 0);
if (!IS_ERR(clk))
dai->sysclk = clk_get_rate(clk);
The sysclk come from the first clock, then first clock is hclk_i2s
in i2s for rk3036 dtsi.
So, we can override the clocks to fit the simple card in here.

It's not that effective, doing that change on a per-board level - as it
would possibly need to be repeated for future boards.
The i2s driver doesn't care, as it uses named clocks, so I instead did
the swap in the rk3036.dtsi for all boards. Can you check if that is ok
for you or if I did overlook something?
Thanks
Heiko

Subject: [PATCH] ARM: dts: rockchip: swap i2s clock ordering on rk3036
For sound setups using the simple-card mechanism, the main clock
(sysclk) is expected to be the first element. For the i2s-driver
itself it doesn't matter, as it uses named clocks, so we can just
swap them.

SCLk_I2S_OUT is the noc bus clock for i2s module, this clock is used by
extra codecs.
Due to it shouldn't belong to any driver, but we need it enabled,
so just mark it as the CLK_IGNORE_UNUSED flag.

What makes you think it shouldn't belong to any driver?
In most schematics I have, i2s_clkout is going to some clock-input of the
audio codec - probably the MCLK input on your rt5616. And while the new
rt5616 driver does not seem to do clock handling, it should just handle the
clock using the normal APIs.

You are right, that's seem has to find the root cause.
I'm wonder that the codec/i2s is working in kernel v4.1 patch without it.
In general, the MLCK will be handled in i2s driver if the cpu side is
master.

looking at the rt5616 datasheet, that would be BCLK1 instead I think. This
one does differentiate between being master/slave.
The master/sysclk (mclk) is also handled in other drivers in all cases.

This patch adds the exteral vcc optional for the simple power sequence.
Some WLAN chips attached to a SDIO interface, need an external vcc
to be operational. Since this is very common, extend the simple MMC
power sequence DT binding to support an optional exteral vcc.

s/exteral/external in the subject line and other places.
I think that makes sense to extend the simple power sequence provider
to add a regulator since many SDIO chips may needed it but it seems
from the commit message of patch 06/12 that you don't actually need
a regulator but to toggle a WL_REG_ON pin in your WiFi chip.
I'll answer to that patch though.

This patch enables support for power-on sequencing of SDIO
peripherals through DT.
In general, it's quite common that wifi modules and other similar
peripherals have several signals in addition to the SDIO interface that
needs wiggling before the module will power on.
For example:
we need enable wifi module power to via the WL_REG_ON
pin, we need enable it as the regulator if this pin is connected to
the gpio of cpu.
Maybe, someone will say that can pull up/down from dts.
Unfortunately some SoCs can't support pinctrl pull up/down in
internal.
Anyway, we can add this patch to supprt the power-on sequencing for
sdio.

I think the subject line and this first paragraph are misleading since
the simple power sequence provider already supports power-on sequencing.
This patch does not add or enable support but extends the current support
to also enable a regulator as a part of the SDIO chip power on sequencing.

This part confuses me, so does your chip have an actual regulator that
needs to be enabled or is just a fake regulator whose gpio property is
used not to enable the regulator but to toggle the WL_REG_ON pin of
the WiFi chip?

Can you please elaborate on this? AFAIU this limitation is the reason
why you went with the regulator approach so I think it deserve a more
deep explanation.

another option would be to use the reset-gpio-handles. rk3288-veyron and I
think some Exynos as well use it that way.

On the rk3036 each pin has an individual unchangable pull direction. So it's
either no bias or pulling in the predefined direction (the pin_default bias
option).

Yes I know, my point was that the reset-gpios property should be used
instead of a fake regulator if what's needed is to toggle a chip pin.

I think each change has to be justified on its own so I would say that
having a regulator enabled as a part of a SDIO chip's power sequencing
is something needed for many platforms, and that this provider should
be extended to support that (something like commit msg in patch 05/12).
And then in the kylin DTS change (patch 08/12), I would explain why a
chained regulators approach is used/needed instead of the reset-gpios
due any platform limitations.

Okay,
I 'm agreed with your points in here.
The reset-gpios/pwrsq can meet the demand of some wlan chips trigger
condition.
No matter whatever is the BT_EN or WL_EN triggers pin.

We want to the higher speed for wifi module working.
Bootup kernel log:
...
mmc_host mmc0: Bus speed (slot 0) = 37125000Hz (slot req 37500000Hz,
actual 37125000HZ div = 0)
or run 'cat /sys/kernel/debug/clk/clk_summary |grep phase -C 1' to check
Otherwise, the mmc0 will run 400khz defalult value to work.

This patch adds the wifi/bt regulator for simple mmc sequence.
Also, add the exteral clock and reset gpios for simple mmmc sequence
on kylin board.
Without this the wifi/bluetooth module doesn't work properly at bootup.
Signed-off-by: Caesar Wang <wxt@rock-chips.com>

Changes in v2:
- As Heiko comment, modify it to fit the simple-mmc-sequence.

We should add the sdmmc but enabling it, since the sdmmc and
uart2 ie reusing the same pin.
That will cause the debug information can't display on console.
Anyway, you only need add the okay status if someone wants to enable
the sdmmc.
e.g.
if you use the adb to debug and run with android os.
you can add the
status = "okay" to enable the sdmmc for sd card working.

The rk3036 support two overlay plane and one hwc plane,
it support IOMMU, and its IOMMU same as rk3288's.
Meanwhile, add the inno hdmi for HDMI display.

Pl330 integrated in rk3036platform doesn't support
DMAFLUSHP function. So we add arm,pl330-broken-no-flushp quirk
for it.

please make sure to split your patch-series at appropriate points for future
versions to only address relevant people. For example I don't think Ulf
really cares about getting the audio-related or general devicetree patches.
