Hi Imre
I got the device in /dev/mmcsd0. I think the reason was that mmcsd wasn't
loaded (need to load manually it seems..)
Do you think your patch in mmc is something that should be pushed upstream
in FreeBSD or is it more of a hack?

Hi Imre
This is great information. Thank you!
My device have an emmc chip on the pcb (non-removable).
Have you tested you code on that kind of system?
Current unmodified FreeBSD can detect the sdhci_pci controller and a mmc
card on slot0 but timeouts when trying to init the mmc. Not sure why it
Hi,
Microsoft has some documentation on GPIO handling with SD card controllers,
which should apply to most Cherryview devices:

I did some work on Cherryview SoC support in DragonFlyBSD.

Why do we need gpio support for emmc/sdhci? Is there a power-enable
pin that
Thanks Adrian
Looks like this is something I can base the new driver on.
Hopefully with this we can get eMMC support for Intel SDHCI controller.

Hi Ian
Thanks for the heads up.
This is a vanilla Intel chip with ACPI.
ACPI ID is INT33FF (Intel Serial IO GPIO Controller).
I don't think I need to worry about FDT. (Hopefully)
I can't find any traces of FDT in the Linux driver.

Take a look at what one of the gpio controllers do. Eg ar71xx_gpio.c.
You have to implement those methods.
(I think someone did a GPIO controller thing for some AMD CPU too?)

Hi
I want to port the pinctrl-cherryview driver from Linux.
I've seen there is the gpiobus and a controller gpioc, can any of these be
leverage when porting pinctrl?
What is the recommend way to proceed?
Thanks!
