Subject[PATCH V3 00/10] interconnect: support i.MX8MP
From: Peng Fan <>

- Drop patch "interconnect: imx: set of_node for interconnect provider"
- Driver License Update
- Correct devm_of_iomap return value check and minor update per ICC
maintainer and Lucas's comments
- Include devfreq patch
- Include device tree patch to include NoC node

Per dt maintainer: drop syscon, move binding file fsl,imx8mp.h out from driver
Per ICC maintainer, add kernel doc and add static inline for an API in header file
Rename max_node_id to num_nodes
Describe more on the registers.

This patchset is to support i.MX8MP NoC settings, i.MX8MP NoC initial
value after power up is invalid, need set a valid value after related
power domain up.

This patchset also includes two patch[1,2] during my development to enable
the ICC feature for i.MX8MP.

I not include ddrc DVFS in this patchset, ths patchset is only to
support NoC value mode/priority/ext_control being set to a valid value
that suggested by i.MX Chip Design Team. The value is same as NXP
downstream one inside Arm Trusted Firmware:

A repo created here:
