[PATCH 0/2] interconnect: qcom: add MSM8x60 NoC driver

[Herman van Hazendonk <github.com@herrie.org>]

Hi all,

This series adds a Qualcomm interconnect provider for the MSM8x60
family of SoCs (MSM8260/MSM8660/APQ8060), modelling the four fabrics
that connect masters and slaves on these Scorpion-class SoCs:

  - AFAB  : Application/CPU fabric
  - SFAB  : System fabric (peripherals, USB, SDCC, etc.)
  - MMFAB : Multimedia fabric (MDP, VFE, VIDC, GPU, JPEG, VPE, ROT)
  - DFAB  : Daytona fabric (low-bandwidth peripherals)

The driver implements the interconnect-provider API so that consumer
drivers (display, camera, video, GPU, USB, MMC) can request bandwidth
between specific masters and slaves via icc_set_bw(), letting the
firmware-managed bus-scaling logic decide actual NoC clock rates.

Used on the HP TouchPad (Tenderloin) and other early Scorpion-class
form-factors; without it, the multimedia and storage paths are starved
of bandwidth and run at minimum NoC clocks.

Thanks,
Herman
