This reverts commit bea8a160c621d19f7f78b13e14e03f4b8e44cd4b.
Contrary to what the commit message says, on my rpi 3 b v1.2 changing
the polarity causes the exact behaviour this commit intends to fix, as
described at the referenced link below (wlan0 disapears).
With reset-gpios = ... GPIO_ACTIVE_HIGH, brcmfmac errors in dmesg:
[ 7.977512] brcmfmac: brcmf_sdio_bus_sleep: error while changing bus sleep state -110
[ 7.977623] brcmfmac: brcmf_sdio_txfail: sdio error, abort command and terminate frame
[ 7.978007] brcmfmac: brcmf_sdio_txfail: sdio error, abort command and terminate frame
[ 7.978377] brcmfmac: brcmf_sdio_txfail: sdio error, abort command and terminate frame
[ 7.978724] brcmfmac: brcmf_sdio_dpc: failed backplane access over SDIO, halting operation
[ 7.978734] brcmfmac: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110
[ 7.978747] brcmfmac: brcmf_cfg80211_get_channel: chanspec failed (-110)
[ 7.982817] brcmfmac: brcmf_sdio_bus_sleep: error while changing bus sleep state -110
[ 7.982880] brcmfmac: brcmf_sdio_txfail: sdio error, abort command and terminate frame
[ 7.983255] brcmfmac: brcmf_sdio_txfail: sdio error, abort command and terminate frame
The only solution I currently have is to revert and everything works
as expected and as before changing the polarity.

This is not the correct way to submit patches for inclusion in the
stable kernel tree. Please read:
https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html
for how to do this properly.

reverting this commit will only workaround the real issue. It lies in the sdhci-iproc driver.
Could please try this instead patch [1]?

Yes, the patch fixes the bug and it's also in Linus' master branch
in v5.0-rc3 as commit 2bd44da ("mmc: sdhci-iproc: handle
mmc_of_parse() errors during prob").
There was just a minor conflict cherry-picking it to 4.19.y
(sdhci_get_property -> sdhci_get_of_property).
I would really like to have 2bd44da backported to the 4.19 stable
tree to have wifi working again. Please?
