[PATCH 0/3] Update to Linux 4.4

[PATCH 0/3] Update to Linux 4.4

[Stefan Agner]

From: Stefan Agner <stefan.agner@toradex.com>

Hi Otavio,

This patchset bumps the Linux kernel to 4.4. For Vybrid we can
now make use of the new DCU DRM driver. I successfully booted an
image on the Tower. However, I do not have the display hence could
not visually verify that the DCU driver works. I previously tested
the driver on our Toradex Colibri VF61 module, where it worked
successfully, hence I assume it should work on the Tower too. The
DRM sysfs files report the correct resolution (for the TWR-LCD-RGB
module):

# cat /sys/class/drm/card0-LVDS-1/*
cat: read error: Is a directory
On
enabled
480x272
cat: read error: Is a directory
connected
cat: read error: Is a directory

Changes since v1:
- Removed old kernel recipe 4.1
- Regenerate common defconfig using savedefconfig too

[PATCH 1/3] linux-fslc (4.4): Introduce Linux 4.4 kernel

[Stefan Agner]

From: Stefan Agner <stefan.agner@toradex.com>

Introduce Linux 4.4 based vanilla Linux kernel. This version
allows to use the DRM DCU driver on Vybrid (with some additional
patches). Also enable PWM support through Vybrid's FlexTimer
module, and update the defconfigs.

With the use of the new DCU DRM driver we can make use of the
X-servers modesetting DDX driver. The driver uses directly the
DRM/KMS interface.

You seem to have based this patch on Jethro branch while you should
have base it on top of master; please rebase it.

While on that, please adjust the SRCREV for the linux-fslc repository
as now it has been merged.
