During "wlan-up", we are programming the FW into the WiFi-chip. However,
re-programming the FW doesn't work, unless a power cycle of the WiFi-chip
is made in-between the programmings.
To conform to this requirement and to fix the regression in a simple way,
let's start by allowing that the SDIO card (WiFi-chip) may stay powered on
(runtime resumed) when wl12xx_sdio_power_off() returns. The intent with the
current code is to treat this scenario as an error, but unfortunate this
doesn't work as expected, so let's fix this.
The other part is to guarantee that a power cycle of the SDIO card has been
completed when wl12xx_sdio_power_on() returns, as to allow the FW
programming to succeed. However, relying solely on runtime PM to deal with
this isn't sufficient. For example, userspace may prevent runtime suspend
via sysfs for the device that represents the SDIO card, leading to that the
mmc core also keeps it powered on. For this reason, let's instead do a
brute force power cycle in wl12xx_sdio_power_on().

Changes in v2:
- Keep the SDIO host claimed when calling mmc_hw_reset().
- Add a fixes tag.

Just tested on both HiKey (620) and Ultra96 but it fails to fix the issue on
both. I'm getting
wl1271_sdio: probe of mmc2:0001:1 failed with error -16
during boot again, and the interface is not available.
Okay, sounds like this may be a different problem then. Can you share
the complete log and the kernel config?
You can find the config here [1], log from the HiKey boot attached.
I can prepare a debug patch as well, if you are willing to re-run the test?
Sure, send it over, I can run it.
Alright, sounds great. However, I need to defer that to Monday/Tuesday
next week.
Adding a post-power-on-delay-ms of 1 ms as you suggested [1], doesn't
sounds like the correct solution to me, unless I am overlooking some
things. The point is, since the mmc core succeeds to detect and
initialize the SDIO card, the power sequence seems to be correct.
Yeah, I'm not claiming at all I know what I'm doing there, just that it happens
to work.
I see. Good to know, thanks!

I have looked through the log and the defconfig. No obvious things
found at this point. Thanks for sharing them!
So, I have put together a debug patch, mostly to verify that things
seems to be correct in regards to runtime PM. It should produce some
prints to the log, particular during power on/off of the SDIO card and
during probe of the wifi driver. Please re-run the test on top of the
v2 version of the $subject patch.
Log attached.
Thanks! Okay, so the re-initialization of the SDIO card is failing,
that's very valuable information.
I noticed one difference while comparing your log with the one I
received (offlist) from Anders... In your case the initialization
frequency that works the first time is 300KHz, while in Anders case
it's 100KHz. This sounds a bit fishy to me, so maybe there are some
problems with the pwrseq after all.
Let me think a bit and see what I can come up with as a possible solution.
In the meantime, can you re-run the test with same debug patch, but
change the post-power-on-delay-ms to let's say 10 ms in the DTS? I am
going to ask Anders to do the same test on his side, as to see if we
get different values of the found initialization frequency.
Here is a log with 10 ms power-on-delay.
