ARM: tegra: add Tegra Note 7 device tree Tegra Note 7 is a consumer tablet embedding a Tegra 4 SoC with 1GB RAM and a 720p panel. The following hardware is enabled by this device tree: UART, eMMC, USB (needs external power), PMIC, backlight, DSI panel, keys. SD card, HDMI, charger, self-powered USB, audio, wifi, bluetooth are not yet supported but might be by future patches (likely in that order). Touch panel, sensors & cameras will probably never be supported. Pinctrl is not set yet, as the bootloader-provided values allow us to use the currently supported hardware. Initrd addresses are hardcoded to match the static values used by the bootloader, since it won't add them for us. All the same, a kernel command-line is provided to replace the one passed by the bootloader which is filled with garbage.

ARM: dts: tegra: move serial aliases to per-board There are general changes pending to make the /aliases/serial* entries number the serial ports on the system. On Tegra, so far the ports have been just numbered dynamically as they are configured so that makes them change. To avoid this, add specific aliases per board to keep the old numbers. This allows us to change the numbering by default on future SoCs while keeping the numbering on existing boards.

ARM: tegra: Correct polarity for Tegra114 PMIC interrupt The ARM GIC only supports interrupts with either level-high or rising-edge types for SPIs. The interrupt type for the Palmas PMIC used for Tegra114 boards is specified as level-low which is invalid for the GIC. This has gone undetected because until recently, failures to set the interrupt type when the interrupts are mapped via firmware (such as device-tree) have not been reported. Since commits 4b357daed698 ("genirq: Look-up trigger type if not specified by caller") and 1e2a7d78499e ("irqdomain: Don't set type when mapping an IRQ"), failure to set the interrupt type will cause the requesting of the interrupt to fail and exposing incorrectly configured interrupts. Please note that although the interrupt type was never being set for the Palmas PMIC, it was still working fine, because the default type setting for the interrupt, 'level-high', happen to match the correct type for the interrupt. Finally, it should be noted that the Palmas interrupt from the PMIC is actually 'level-low', however, this interrupt signal is inverted by the Tegra PMC and so the GIC actually sees a 'level-high' interrupt which is what should be specified in the device-tree interrupt specifier.
