From: Peng Fan <peng.fan@nxp.com> V2: 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: https://source.codeaurora.org/external/imx/imx-atf/tree/plat/imx/imx8m/imx8mp/gpc.c?h=lf_v2.4#n97 A repo created here: https://github.com/MrVan/linux/tree/imx8mp-interconnect Peng Fan (9): dt-bindings: interconnect: imx8m: Add bindings for imx8mp noc dt-bindings: interconnect: add fsl,imx8mp.h interconnect: add device managed bulk API interconnect: imx: fix max_node_id interconnect: imx: set src node interconnect: imx: introduce imx_icc_provider interconnect: imx: set of_node for interconnect provider interconnect: imx: configure NoC mode/prioriry/ext_control interconnect: imx: Add platform driver for imx8mp .../bindings/interconnect/fsl,imx8m-noc.yaml | 6 +- drivers/interconnect/bulk.c | 42 +++ drivers/interconnect/imx/Kconfig | 4 + drivers/interconnect/imx/Makefile | 2 + drivers/interconnect/imx/imx.c | 78 ++++-- drivers/interconnect/imx/imx.h | 50 +++- drivers/interconnect/imx/imx8mm.c | 2 +- drivers/interconnect/imx/imx8mn.c | 2 +- drivers/interconnect/imx/imx8mp.c | 259 ++++++++++++++++++ drivers/interconnect/imx/imx8mq.c | 2 +- include/dt-bindings/interconnect/fsl,imx8mp.h | 59 ++++ include/linux/interconnect.h | 7 + 12 files changed, 490 insertions(+), 23 deletions(-) create mode 100644 drivers/interconnect/imx/imx8mp.c create mode 100644 include/dt-bindings/interconnect/fsl,imx8mp.h
