v5:	* Moved to use gpio-restart for reboots, had to make tegra_pmc_restart
	a notification handler

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 leaf DTs contain the whole pinmux configuration as generated by
tegra-pinmux-scripts. I chose to not put the common configuration in the
common dtsi so we can paste the output as is and be sure that the kernel
doesn't diverge from the canonical data.

These patches are based on top of linux-next 20150212.
