In vendor tree there is something called busfreq but it is
non-upstreamable. This approach with interconnect+devfreq gives us the
same functionality by using already upstream and mature subsystems.
This series is more of a proof-of-concept.

Abel Vesa (19):
dt-bindings: interconnect: imx8mq: Add missing pl301 and SAI ids
devfreq: imx-bus: Switch governor to powersave
devfreq: imx-bus: Decouple imx-bus from icc made
devfreq: imx8m-ddrc: Change governor to powersave
devfreq: imx8m-ddrc: Use the opps acquired from EL3
devfreq: imx8m-ddrc: Add late system sleep PM ops
interconnect: imx: Switch from imx_icc_node_adj_desc to fsl,icc-id
node assignment
interconnect: imx8: Remove the imx_icc_node_adj_desc
interconnect: imx8mq: Add the pl301_per_m and pl301_wakeup nodes and
subnodes
interconnect: imx8mq: Add of_match_table
interconnect: imx: Add imx_icc_get_bw and imx_icc_aggregate functions
arm64: dts: imx8mq: Add fsl,icc-id property to ddrc node
arm64: dts: imx8mq: Add fsl,icc-id to noc node
arm64: dts: imx8mq: Add all pl301 nodes
arm64: dts: imx8mq: Add the interconnect node
arm64: dts: imx8mq: Add interconnect properties to icc consumer nodes
net: ethernet: fec_main: Add interconnect support
mmc: sdhci-esdhc-imx: Add interconnect support
arm64: defconfig: Add necessary configs for icc+devfreq on i.MX8MQ
