Please review and apply, thanks in advance. Changelog: v5: - After spending some more time on adding LVDS encoder bridge support to the Tegra DRM driver, I'm now having a second thought and agree with Thierry Reding that in a longer run it should be better not to mix old nvidia,panel with new output graph in device-tree. So the nvidia,panel phandle is removed now in both A500 and Nexus 7 DTs. v4: - Corrected CPU's thermal zone on both A500 and Nexus 7, which should use the remote thermal sensor (Tegra chip) instead of the local ("skin" temperature). - Added default PMIC pinmux state on Nexus 7, for completeness. - Added PMIC cpu_pwr_req GPIO hog on Nexus 7, for completeness. - Renamed thermal sensor node label to NCT72 on Nexus 7 to match the actual hardware (NCT72 is compatible with NCT1008). For completeness. - Added always-on USB AVDD regulator on Nexus 7, which is controlled by the PMIC GPIO. For completeness. - Added PMIC GPIO enable-control to the 3v3_sys regulator on Nexus 7, for completeness. - Added CONFIG_NAMESPACES, CONFIG_USER_NS, CONFIG_SECCOMP and CONFIG_PINCTRL_MAX77620 to the tegra_defconfig. The first three options are must-have for the modern userspace, the last is somewhat actual now since the default PMIC pinmux state is added to the N7 DT. v3: - Improved device-tree node-names in accordance to review comments that were made by Thierry Reding to v2. - Corrected LVDS encoder powerdown-GPIO polarity on both A500 and Nexus 7 because I implemented the DRM bridges support in the Tegra DRM driver and found that there was a mistake in the device-trees. The updated polarity also matches the boards schematics. Now DRM bridges support becomes mandatory since LVDS is getting disabled during of the encoder driver probing. I'll send the DRM patch separately from this series. - Replaced recently deprecated CONFIG_DRM_LVDS_ENCODER with the new CONFIG_DRM_LVDS_CODEC in tegra_defconfig. - Added more config options to tegra_defconfig, like pstore and thermal. - Added atmel,cfg_name to the A500 DT, which is a new upcoming property in 5.8+ that allows to specify the per-board hardware config file name. v2: - Corrected "volume down" key-label in the grouper's device-tree and improved some other names in device-trees. - Added optional (upcoming in 5.8+) VDD/AVDD regulators to the touchscreen node in A500 device-tree.
