This is a plain old shitty situation, that everyone that mistakenly chooses a BRCM based chipset in a design faces, then learns to NEVER touch that chipset again.. These nodes have been posted before for mainline inclusion but always get killed off: https://lkml.org/lkml/2018/3/18/356 The TI AM57xx SDIO needs these flags for the brcmfmac driver to actually work. I don't see the brcmfmac developers actually fixing it, as "out of tree" work for brcmfmac is 100+ patches long: https://www.cypress.com/documentation/software-and-drivers-archive/wifi-bt-linux-archive?source=search&cat=other Regards,

Sorry Krzysztof, I forgot that a login is required, here is a quick mirror (with a screenshot of the page.) https://rcn-ee.net/workshops/cypress-fmac/ Screenshot: https://rcn-ee.net/workshops/cypress-fmac/brcm.png There patch with that binding: https://rcn-ee.net/workshops/cypress-fmac/cypress-fmac-v5.4.18-2021_0114/cypress-patch-v5.4.18-2021_0114/cypress-patch/0002-non-upstream-add-sg-parameters-dts-parsing.patch Thank You!
