 - CMT0/1
 - HSCIF
 - MSIOF
 - RPC
  - not for upstream because RPC shall only be accessed via OPTEE. See BSP commit 1f83a133b853138fad712d0a08a7689aac1e0183 ("Disable SPI flash via RPC")
 - SCIF
 - SD/MMC
 - THS/CIVM
  - first version sent
 - TMU
  - probably possible; pinmux to TCLK1-4 and check via non-populated I2C header on breakout board
 - all other devices are in the control domain which we do not handle. Only the application domain is our job.
  - for a domain overview, check '001_R-CarS4_Bus Architecture_Rev0p70.pptx' (attachment in the S4 docs)
