It just causes a constant rate of 5000 interrupts per second for both
GPIO and MMC, even if nothing is happening. Rely on in-band interrupts
instead.

What WiFi chip/module does this use? It might be worth asking Broadcom
people to help with this and fix the driver.

Based on the comments in the device tree file, it uses an AP6210, which
is a BCM43362 inside for SDIO-based WiFi. There is a recent fix in 5.6-rc1
for this,

    8c8e60fb86a9 brcmfmac: sdio: Fix OOB interrupt initialization on brcm43362

which seems to fix things for me. Could you try it on your end?

Interesting, thanks for finding out! I'll test it.

I think it will work, since my tablet started having overheating issue recently,
and I tracked it down to this.

I can confirm that it works as you say (on linus/master). 5.5 still doesn't have
the patch, so it's broken there, which confused me I guess.

Please ignore this patch.

thank you,

Hi Ondrej,

I have seen emails from GregKH including this patch in 5.5 stable so it 
will also land there eventually.
