No hdmi-cec on Utilite (3.14.14)

[setti]

It's me again.
I just found out that I'm missing /dev/mxc_hdmi_cec
Kernel is built with CONFIG_MXC_HDMI_CEC=y and dtb should contain cec entry as it was built with imx6q.dtsi dependency which in turn contains $this->bbcode_second_pass_code('', ' hdmi_cec: hdmi_cec@00120000 {
compatible = "fsl,imx6q-hdmi-cec";
interrupts = <0 115 0x04>;
status = "disabled";
};
')
I didnt find any hdmi-cec part mentioned anywhere else on the deps list of imx6q-sbc-fx6m.dtb
$this->bbcode_second_pass_code('', '
cmd_arch/arm/boot/dts/imx6q-sbc-fx6m.dtb := gcc -E -Wp,-MD,arch/arm/boot/dts/.imx6q-sbc-fx6m.dtb.d.pre.tmp -nostdinc -I/var/abs/local/linux-utilite-dt/src/linux-kernel-9109d913ef44141f97e1237ed908fba4f43a4010/arch/arm/boot/dts -I/var/abs/local/linux-utilite-dt/src/linux$

source_arch/arm/boot/dts/imx6q-sbc-fx6m.dtb := arch/arm/boot/dts/imx6q-sbc-fx6m.dts

deps_arch/arm/boot/dts/imx6q-sbc-fx6m.dtb := \
arch/arm/boot/dts/imx6q-sb-fx6m.dtsi \
arch/arm/boot/dts/imx6q-sb-fx6x.dtsi \
arch/arm/boot/dts/imx6q.dtsi \
arch/arm/boot/dts/imx6q-pinfunc.h \
arch/arm/boot/dts/imx6qdl.dtsi \

arch/arm/boot/dts/imx6q-cm-fx6.dtsi \

arch/arm/boot/dts/imx6q-sbc-fx6m.dtb: $(deps_arch/arm/boot/dts/imx6q-sbc-fx6m.dtb)

$(deps_arch/arm/boot/dts/imx6q-sbc-fx6m.dtb):')

So cec is not enabled in dts is my guess. On my wandboard I had to manually add$this->bbcode_second_pass_code('', '&hdmi_cec {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_hdmi_cec_2>;
status = "okay";
};
')
But I dont know how the part should look like for utilite. Any ideas?

Where did you get the kernel package from?

From you
https://github.com/archlinuxarm/PKGBUIL ... utilite-dt

Something is strange....
Ive added the following to arch/arm/boot/dts/imx6q-sbc-fx6m.dts
$this->bbcode_second_pass_code('', '&hdmi_cec {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_hdmi_cec_2>;
status = "okay";
};')
Like i did on my wandboard.
After reboot cec-client -l finds my device. But i dont get a connection to my tv. The cec-client command hangs like it is waiting for some answer.
$this->bbcode_second_pass_code('', 'root@utilite - 16:54:49 - ~ # cec-client -l

')

Some one else having cec running on his utilite? I hope, the cec pins are soldered correctly on my utilite.

That's 3.10.70 not 3.14.14
It might need so CEC patches, and I'm busy for next fortnight moving.

Want to look at the cubox-I patches?

Ive made a fork of your linux-kernel repo and already added your package patches into kernel repo.
I applied the cubox-i cec patches and afterwards I changed the arch package a bit and kernel is building fine with the config changes, mentioned in viewtopic.php?f=45&t=8547#p45593.
I also had to define a udev rule for /dev/mxc_hdmi_cec
$this->bbcode_second_pass_code('', '# cat /etc/udev/rules.d/99-hdmi-cec.rules
KERNEL=="mxc_hdmi", SUBSYSTEM=="mxc_hdmi", GROUP="video", MODE="0660"
KERNEL=="mxc_hdmi_cec", SUBSYSTEM=="mxc_hdmi_cec", GROUP="video", MODE="0660"')

Three days ago I modified my old Wandboard for cec following by these Instructions:
https://www.project-insanity.org/blog/2014/01/24/wandboard-with-hdmi-cec-and-xbmc/

For now, I'm also missing /dev/mxc_hdmi_cec on my Wandboard.

Please tell me how to insert/compile your cec-snippet into the dtb-file to make it work.

I think it will be the best for future to inform the maintainer of the kernel-package. (How?)
