Device Tree port

Table of Contents Implemented Branches Current TODO Impractical Unsuitable

Implemented

• irq handler
• mmio clocksource
• mmio clockevent (system timer)
• sp804 (to detect and disable it)
• uart0 (pl011)
• watchdog
• clk/clkdev (not dt)
• bcm-mbox (aka vcio)
• fb
• video logo
• bcm-bell
• system_serial/system_rev/mac_address
• bcm-vc-power (currently both devices are always on)

Branches

• lp0/rpi01-mach (rebased continuously)
• lp0/rpi02-plat (rebased continuously)
• lp0/rpi-linear

Current

• lp0/rpi-next (gpio)

TODO

• clk/clkdev (when it gains dt support)
• gpio
• gpio irq
• ok-led (needs gpio)
• usb (uses bcm-vc-power, hack in the current dwc_otg code until a proper driver is merged)
• ethernet mac address (tricky, some way to absolutely identify that the usb device is the board's and not from somewhere else on the bus might help)
• dma irq (aka dmaman)
• mmc/emmc (aka sdhci, needs dma, uses bcm-vc-power)
• pinmux (needed by everything that uses a configurable pin)
• audio
• spi
  • bootc/rpi-spi
• spi irq
• spi dma
• i2c
• i2c irq
• i2c dma
• pwm

Impractical

• vchiq (aka vc04/vcos, uses bcm-mbox, bcm-bell, requires a major rewrite without breaking the ABI)

Unsuitable

• vc-mem (this will need to use sysfs not /proc)
