[RFC 00/19] Add interconnect and devfreq support for i.MX8MQ

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
