Add SDIO interrupt support. Successfully tested on a S905X4-based
system (V3 register layout) with a BRCM4334 SDIO wifi module
(brcmfmac driver).
v2:
- use new SDIO interrupt API
v3:
- don't duplicate checking mmc->sdio_irq_pending

* [PATCH v3 2/2] mmc: meson-gx: add SDIO interrupt support
@ 2022-08-25 19:56 ` Heiner Kallweit

Add SDIO interrupt support. Successfully tested on a S905X4-based
system (V3 register layout) with a BRCM4334 SDIO wifi module
(brcmfmac driver).
Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com>

v2:
- use new SDIO IRQ API
v3:
- don't duplicate checking mmc->sdio_irq_pending
Device works fine w/o it.

Thanks for applying, but I was off (like many of reviewers) and I would have like
this patchset to be tested on earlier SoCs aswell, or only enabled on S4 for now.

To actually make use of the new code, an update to the corresponding
DTS files are needed to set the cap-sdio-irq property.
If that isn't sufficient, I prefer if we make a patch on top of the
$subject series.

I know but it changed the IRQ handling, let's hope we don't see any regressions.

Right. Let's encourage people to test this!
I noticed that $subject patch sets the CLK_IRQ_SDIO_SLEEP bit, no
matter whether the SDIO IRQs has been enabled. Don't know if that is
intentional and/or could be a problem? Heiner?
