- The device tree branch can now be pushed upstream and usb, ethernet mac, audio, vchiq and vc-mem can be added on in a local branch for now so that everything is still working
- How to Boot using Device Tree
- The bcm_dma_* exports are gone - the kernel already has a DMA API
- Issue #24
- The supplied usb driver has broken locking and writes beyond the areas it mallocs
- The usb chip itself isn't very good
- 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
- pinctrl
- pinmux
- gpio
- ok-led
- gpio irq
- spi
- i2c
- dma
- sdhci pio
- sdhci dma
- lp0/rpi-split (rebased continuously)
- lp0/rpi-linear
- lp0/rpi-next (none)
- lp0/rpi-usb (my dwc2_hcd attempt)
- lp0/rpi-usb2 (APM dwc otg driver)
- clk/clkdev (when it gains dt support)
- pinconf (for pull high/low)
- spi dma
- i2c dma
- 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)
- pcm/i2s
- pwm
- gpio clock (the clk subsystem can be used to turn these on/off and configure them)
- audio (requires vchiq)
- vchiq (aka vc04/vcos, uses bcm-mbox, bcm-bell, requires a major rewrite without breaking the ABI)
- csi (hidden) :(
- vc-mem (this will need to use sysfs not /proc)
