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 20150128.

Tomeu
