[meta-freescale] Patch submission to Freescale kernel

[Gary Bisson]

Hi,

I was wondering what was the procedure to submit a patch to the 
Freescale maintained kernel:
http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/

I've just made a patch that fixes the display issue for rev T1.0 of the 
SoC which has been previously reported:
https://lists.yoctoproject.org/pipermail/meta-freescale/2014-May/008553.html
"mxc_sdc_fb fb.27: timeout when waiting for flip irq"

Then, I'd like to send that patch over to the fslc and mainline kernels 
as they seem to have the issue by checking their source code.

Regarding the mainline kernel, I can't seem to get the HDMI (on 
nitrogen6x) to work at all no matter which revision/board I use. Looking 
into the source code I've seen the evolution of the 
drivers/staging/imx-drm driver which tends to say that HDMI is 
supported. If so, would anyone have some insights on which command line 
to pass the kernel in order to get the mainline kernel to recognize the 
HDMI display properly. So far the init seems to be fine but fb0 sysfs 
modes is just rubbish.
