<amitk> javier__: did you have a chance to look at the wifi on the cb2?
<amitk> that is the only thing that is stopping me from using the cb2 as my daily laptop
<javier__> amitk: I did and got it working on snow but I couldn't get it working on peach pit/pi
<amitk> javier__: same chip?
<javier__> amitk: no, but the needed DTS changes are similar
<javier__> amitk: this is my wip branch fwiw http://cgit.collabora.com/git/user/javier/linux.git/log/?h=wip/exynos/wifi

<amitk> javier__: thanks, I'll play around to see if I can get it working over the holidays
<javier__> amitk: cool, the problem is that the dw_mmc driver is timing out when sending mmc commands
<javier__> "mmc_host mmc2: Timeout sending command (cmd 0x202000 arg 0x0 status 0x80202000)"

<amitk> javier__: I'll try to get Ulf to look at it (helps to have the mmc maintainer working in the team) ;)
<javier__> amitk: it does indeed :)
<javier__> amitk: I found that this ugly workaround make the error to go away and at least the wifi chip is listed in /sys/bus/sdio but the wifiex driver hangs when trying to download the firmware to the chip
<javier__> amitk: seems to be some timing issue but I've to admit to not be very familiar with mmc/sdio in general so having ulf to take a look would be great!
<javier__> amitk: btw, are the desktop images you are using for the cb2 public?
<amitk> javier__: no

<javier__> amitk: one last comment about the wifi wip patches, I'm using some out-of-tree patches from Olof that adds power on sequencing support for sdio devices
<javier__> amitk: the downstream ChromiumOS kernel (and some mainline DTS) use a chain of faked fixed regulator just to toggle the GPIO on the right sequence
<javier__> but that does not work for the wifi chip in the cb2 because it also needs a reference clock (which was modelled in the downstream tree as a regulator instead of a clock driver)
<javier__> amitk: afaiu ulf is working on a generic support for mmc/sdio power on sequencing
<javier__> amitk: sorry for the spam but I thought that it may be interesting to share my findings with you :)
