Status

Component Status Assigned To Comments Meta Comments
SPI1/2 driver in 4.4, need to merge DT in 4.6. msperl
UART1 needs review feedback handling msperl
one-shot DMA in review notro
thermal in review lkundrak Current implementation RPi-only
cpufreq in review lkundrak Current implementation RPi-only
Audio Depends on DMA and/or Mailbox (codec/digi/dac) Which one(s)
VCHIQ lkundrak Depends on mailbox. Requires big clean-up. Staging candidate? Does this depend on DMA?
Sound lkundrak I2S is already in. Depends on VCHIQ Does this depend on DMA?
MMC Semi-Upstreamed pietrushnic drivers/mmc/host/sdhci-bcm2835.c - lacking DMA Depends on DMA slave_sg transfer mode
SDHOST MMC Needs cleanup anholt WIP cleanups
Camera Needs VCHIQ for MMAL
Video decode Needs VCHIQ for MMAL
RPi2 Upstreamed (4.5) anholt
GPU (DRM) Upstreamed (4.5) anholt See also Instructions.
Power Upstreamed (4.5) anholt Current implementation RPi-only, requires current firmware for full functionality
Framebuffer Deprecated, use DRM instead Depends on Mailbox
mailbox Upstream (4.4) anholt Mailbox driver landed in 4.3, 4.4 will have firmware interfaces built on it
clocks-aux Upstream (4.5) anholt Supports setting SPI1, SPI2, UART1 clocks
clocks-audio Upstreamed (4.4) anholt Native support for setting most clocks on the system.
Clock Source Upstreamed drivers/clocksource/bcm2835_timer.c
