11:15 <Tofe_> Hi ! I'm currently working on mainlining the old HP touchpad (tenderloin, based on msm8660), but I have an issue with the wifi card this isn't picked up at all; it's supposed to be connected via SDIO to the MMC controller, but I think it's not powered or something like that... are there some examples out there of dts files doing that ?

14:11 <phh> Tofe_: yes you need to use a mmc-pwrseq, https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/amlogic/meson-g12a-fbx8am.dts#L395

14:17 <Tofe_> phh: ah, thanks; I tried that but it didn't work, however it's very possible I did it wrong

14:17 <Tofe_> I'll check my dts again

14:23 <phh> what you can try is add `broken-cd;` in the mmc node, and triggering the gpio manually from userspace with gpio_sysfs

14:25 <Tofe_> I'll try that too thanks

14:27 <phh> (cd is "card detect" it's a pin to know whether the sdcard is inserted or not, since the wifi chip is embedded there is no such pin, so "broken-cd" tells the mmc controller to just try initing the device in loop)

14:28 <Tofe_> so if my regulator config is incorrect, broken-cd might help working around it

14:49 <phh> well you still need to power on the regulators

14:56 <Tofe_> yes, sure :)
