Subject: [PATCH v4 00/11] Improvements to Tegra-based Chromebook support

v4:	* Added support for the system reset GPIO, for proper reboots
	* Moved out changes to ASOC to their own series, as requested by Mark
	Brown
	* Added patch to reset the SOR, to make sure it's in a known state
	* Changed nvidia,model property of the sound nodes to GoogleNyanBig
	and GoogleNyanBlaze so they can be told apart in userspace

v3:	* Added bindings for the LTN140AT29 panel
	* Removed the delay in pwrseq, as what was actually needed was to add
	a dependency on the power supplies of the host
	* Uses the pinmux for the Blaze as generated by tegra-pinmux-scripts
	* Uses the pinmux for the Big as in the last patch from Simon Glass

Hello,

this series adds support for the Tegra-based HP Chromebook 14 (aka nyan
blaze), which is very similar to the Acer Chromebook 13 (aka nyan big).
Because they both include tegra124-nyan.dtsi, some improvements to Blaze
support have also benefitted the Big. I have tested that USB2, the panels,
HDMI, the trackpad, Wifi and sound work on both.

The DT for the Big includes the pinmux configuration as generated by
tegra-pinmux-scripts with Simon's patch at:

https://patchwork.ozlabs.org/patch/417779/

These patches are based on top of linux-next 20150211.

Tomeu
