<issoeocio> Hello
<javier__> issoeocio: I've seen your questions before, your usb_boot command looks correct, but it depends on what is the value of the different variables to tell if is doing what you want
<javier__> issoeocio: I don't understand what you mean by extramodules
<issoeocio> I resolved that.
<issoeocio> I have another question. I installed the last kernel 4.1
<issoeocio> and lost trackpad
<issoeocio> the snow dts in the last version change atmel,maxtouch to other
<issoeocio> to cypress,cyapa
<issoeocio> my board is xe303c12-ad1br
<issoeocio> xe303c12 is snow/daisy
<issoeocio> but seems that the version br (Brazil) have other specifications...
<issoeocio> in /proc/bus/input/device on the ChromeOS says atmel/maxtouch
<javier__> issoeocio: where is the change you are referring to? but in any case cypress,cyapa is the correct compatible for the trackpad in Snow and atmel,maxtouch for peach pit/pi
* javier__ is confused
<issoeocio> the exynos5250-snow.dts from the lasts kernels says now cypress/cyapa
<javier__> issoeocio: yes, that's the correct one and I can't find where it had a different compatible string before
<issoeocio> well my board show atmel,maxtouch in ChromeOS
<issoeocio> is a xe303c12-ad1br
<javier__> mmm I wonder if there was a special Snow version for Brazil which used the atmel trackpad
<javier__> issoeocio: but I'm not able to find such a DTS in the downstream ChromiumOS v3.8 kernel tree
<javier__> issoeocio: which kernel version do you have in ChromeOS?
<issoeocio> 3.8.11 I think... I will check
<javier__> issoeocio: yes, that's the branch I'm looking and I see that all exynos5250 machines use cyapa
<javier__> arch/arm/boot/dts/cros5250-common.dtsi: compatible = "cypress,cyapa";
<issoeocio> strange...
<issoeocio> I will send pictures.
<javier__> is the first time I heard of a Snow that uses atmel,maxtouch
<javier__> issoeocio: can you share the output of dmesg after booting the ChromeOS kernel?
<issoeocio> i will do that too

<javier__> issoeocio_: so it does have a atmel chip, how weird. There isn't a suitable DTS in the downstream tree
<javier__> issoeocio_: you may need to post a new DTS for this Snow variant and factoring out the current Snow DTS in a DTSI
<javier__> issoeocio_: basically what you need is to take the exynos5420-peach-pit atmel device node and add it to the Snow DTS
<issoeocio_> I will have to research how to do that. Strange that the 3.4 kernel was working.
<javier__> issoeocio_: where did 3.4 came from? definitely not mainline
<issoeocio_> I don't know. It was a installation of Archarm.
<javier__> issoeocio_: do you have a pointer to the source code of that?
<issoeocio_> https://github.com/archlinuxarm/ seems to
<javier__> issoeocio_: right, arch/arm/boot/dts/cros5250-common.dtsi has a trackpad-alt
<javier__> but is wrong to have 2 i2c devices on a bus if only one will be present in a given board
<javier__> the right thing to do is to have 2 different DTS

<issoeocio> I will try to combine those and see what happens.
<issoeocio> Yeah.
<javier__> issoeocio: you only need to change that, I didn't know there were variants of snow using that chip
<javier__> issoeocio: yep, most Snow use max98095 instead but I was aware about that variant
<issoeocio> with "you only need to change that" you mean add that to what? the 4.1 don't have a cros5250-common.dtsi
<issoeocio> I will do the same approach to the maxim
<javier__> issoeocio: yes
<javier__> that should give you trackpad and sound working but as I said the correct approach is to have different DTS that include the same base DTSI
<javier__> and only changing the maxim codec and i2c trackpad description
<javier__> issoeocio: I mean, if you don't want to carry that patch
<issoeocio> I don't know how to create one. I'm a philosopher, I learned to apply a patch only yesterday.
<issoeocio> Nop. No trackpad.
<javier__> issoeocio: did you have a error on booting? did the driver probed correctly?
<issoeocio> did not probed
<issoeocio> I will retry with exynos_defconfig...
<issoeocio> It works with exynos_defconfig
<issoeocio> the sound not yet
<javier__> issoeocio: yeah so probably CONFIG_TOUCHSCREEN_ATMEL_MXT is not enabled in your defconfig
<issoeocio> ok. It recongnizes the touchpad... but it's no possible to click and it's having erratic movements
<issoeocio> eratic*
<javier__> issoeocio: right, I missed some bits that you also need http://hastebin.com/foxufuluso.diff
<javier__> that *should* be enough afaict
<javier__> issoeocio: sorry, I'm quite busy with other stuff so I can't really focus on this issue :)
<issoeocio> Of course. Thanks for the attention.
<javier__> issoeocio: no worries, just to let you know that I'm more distracted than usuaul
<javier__> issoeocio: I'm leaving for today, hope the last patch worked for you
<issoeocio> Yeah. It works. I will try to combine things for sound.
<issoeocio> You take the "linux,gpio-keymap = <KEY_RESERVED" from where?
<javier__> issoeocio: arch/arm/boot/dts/exynos5420-peach-pit.dts in mainline
<issoeocio> Ok. Thanks for the help.
<javier__> issoeocio: you are welcome
<javier__> bye
