regression: twl4030 audio/clock stopped working in v4.16

regression: twl4030 audio/clock stopped working in v4.16

[H. Nikolaus Schaller]

Hi Peter,
I just noticed a problem in v4.16 kernels with twl4030 audio and vibra driver no longer working.

Tracing it back shows that it already did appear in v4.16-rc1 and wasn't fixed up to v4.16.0.
Kernel v4.15.9 (the latest one where I have a binary) works.

The symptoms are:

[    1.557342] twl4030-audio 48070000.i2c:twl@48:audio: Invalid audio_mclk
[    1.564788] twl4030-audio: probe of 48070000.i2c:twl@48:audio failed with error -22
[    1.839141] TWL4030: HFCLK is not configured

Those are not visible in v4.15.9. And I am not aware of any changes to the gta04 device tree.

Do you know about this issue and a fix, before I start to bisect?

BR and thanks,
Nikolaus

Nikolaus,

can you CC me also, I have almost missed this...

v4.16 works just fine on beagle-xm (including audio), omap2plus_defconfig.

Hrm, the order looks a bit weird, it should be
TWL4030: HFCLK is not configured
twl4030-audio 48070000.i2c:twl@48:audio: Invalid audio_mclk
twl4030-audio: probe of 48070000.i2c:twl@48:audio failed with error -22

In twl4030_audio_probe() we try to get the HFCLK rate via
twl_get_hfclk_rate(), which is reading it with:
twl_i2c_read_u8(TWL_MODULE_PM_MASTER, &ctrl, R_CFG_BOOT);

The CFG_BOOT register of twl4030 is not configured correctly for some
reason?
The TRM of twl4030 states that the SW should program the HFCLK_FREQ
during boot sequence.

If it is not done, MDAC and USB should not work either. And all sorts of
other issues might happen.

So the boot loader is not configuring the HFCLK_FREQ, for me it does as
I have this line in the kernel log:
[    1.472503] Skipping twl internal clock init and using bootloader
value (unknown osc rate)

In DT the twl should have the fck clock to not depend on the bootloader
for the HFCLK_FREQ settings. We do not have that for beagle-xm for sure.

there is a bug in twl-core for getting the clock:
https://marc.info/?l=linux-omap&m=152292879928720&w=2

and a patch for beagle-xm to add the fixed clock:
https://marc.info/?l=linux-omap&m=152292917328832&w=2

With these two, beagle-xm no longer depends on bootloader to set the
HFCLK_FREQ for twl4030.

Ah, good. Thanks for quick response! I was just starting to setup git bisect...

Well, USB works for me... Strange.

So I can see this as well.

I am not even modifying the bootloader when trying v4.15 and v4.16. I just
swap uImage and kernel modules...

The interesting question is why it did work before (for years) and stopped with v4.16-rc1.

I think it got broken because of these:
7558562a70fb clk: ti: Drop legacy clk-3xxx-legacy code
0ed266d7ae5e clk: ti: omap3: cleanup unnecessary clock aliases

These used to wire the twl's fck to osc_sys_ck, but they are gone in 4.16.
