ARM: dts: bcm283x: Add dtsi for USB host mode In case dr_mode isn't passed via DT, the dwc2 defaults to OTG mode. But all Raspberry Pi boards here are designed only for host mode. So fix this issue by providing a dtsi file which set the dr_mode to host.

ARM: bcm2835: Add names for the Raspberry Pi GPIO lines The idea is to give useful names to GPIO lines that an implementer will be using from userspace, e.g. for maker type projects. These are user-visible using tools/gpio/lsgpio.c v2: Major rewrite by anholt: Flatten each GPIO line to a line in the file for better diffing, prefix all expansion header pins with "P<number>" or "P5HEADER_P<number>" and drop the mostly-unused GPIO_GEN<smallnumber> names in favor of GPIO<socgpionumber>, fix extra '[]' on a couple of lines, fix locations of SD_CARD_DETECT, CAM_GPIO and STATUS_LED, fix HDMI_HPD polarities, rewrite A+ using unreleased schematics. v3: More changes by anholt: Drop P<number> / P5HEADER<number> prefixes. I had been skeptical about adding them, and was convinced to drop them by Gottfried (who probably has more experience with GPIOs in educational contexts than the rest of us). Also drop [] brackets for "is pinmuxed", which didn't seem to clarify, and were ambiguous for things like the SPI_*-labeled pins which may or may not actually be pinmuxed to SPI. v4: Rename B+'s SDA0/SCL0 to match the other boards, despite the naming on its schematic.

ARM: bcm2835: Fix names for the Raspberry Pi GPIO lines There are some differences between the schematics and the official firmware DTS [1].

ARM: bcm283x: Define UART pinmuxing on board level Until RPI 3 and Zero W the pl011 (uart0) was always on pin 14/15. So in order to take care of them and other boards in the future, we need to define UART pinmuxing on board level. This work based on Eric Anholt's patch "ARM: bcm2385: Don't force pl011 onto pins 14/15." and Fabian Vogt's patch "ARM64: dts: bcm2837: assign uart0 to BT and uart1 to pin headers".
