-t7xx devlink support
-====================
-
-This document describes the devlink features implemented by the ``t7xx``
-device driver.
-
-Flash Update
-============
-
-The ``t7xx`` driver implements the flash update using the ``devlink-flash``
-interface.
-
-The driver uses DEVLINK_SUPPORT_FLASH_UPDATE_COMPONENT to identify the type of
-firmware image that need to be programmed upon the request by user space application.
-
-The supported list of firmware image types is described below.
-
-.. list-table:: Firmware Image types
-    :widths: 15 85
-
-    * - Name
-      - Description
-    * - ``preloader``
-      - The first-stage bootloader image
-    * - ``loader_ext1``
-      - Preloader extension image
-    * - ``tee1``
-      - ARM trusted firmware and TEE (Trusted Execution Environment) image
-    * - ``lk``
-      - The second-stage bootloader image
-    * - ``spmfw``
-      - MediaTek in-house ASIC for power management image
-    * - ``sspm_1``
-      - MediaTek in-house ASIC for power management under secure world image
-    * - ``mcupm_1``
-      - MediaTek in-house ASIC for cpu power management image
-    * - ``dpm_1``
-      - MediaTek in-house ASIC for dram power management image
-    * - ``boot``
-      - The kernel and dtb image
-    * - ``rootfs``
-      - Root filesystem image
-    * - ``md1img``
-      - Modem image
-    * - ``md1dsp``
-      - Modem DSP image
-    * - ``mcf1``
-      - Modem OTA image (Modem Configuration Framework) for operators
-    * - ``mcf2``
-      - Modem OTA image (Modem Configuration Framework) for OEM vendors
-    * - ``mcf3``
-      - Modem OTA image (other usage) for OEM configurations
-
-``t7xx`` driver uses fastboot protocol for fw flashing. In the fw flashing
-procedure, fastboot command's & response's are exchanged between driver
-and wwan device.
-
-The wwan device is put into fastboot mode via devlink reload command, by
-passing "driver_reinit" action.
-
-$ devlink dev reload pci/0000:$bdf action driver_reinit
-
-Upon completion of fw flashing or coredump collection the wwan device is
-reset to normal mode using devlink reload command, by passing "fw_activate"
-action.
-
-$ devlink dev reload pci/0000:$bdf action fw_activate
-
-Flash Commands:
-===============
-
-$ devlink dev flash pci/0000:$bdf file preloader_k6880v1_mdot2_datacard.bin component "preloader"
-
-$ devlink dev flash pci/0000:$bdf file loader_ext-verified.img component "loader_ext1"
-
-$ devlink dev flash pci/0000:$bdf file tee-verified.img component "tee1"
-
-$ devlink dev flash pci/0000:$bdf file lk-verified.img component "lk"
-
-$ devlink dev flash pci/0000:$bdf file spmfw-verified.img component "spmfw"
-
-$ devlink dev flash pci/0000:$bdf file sspm-verified.img component "sspm_1"
-
-$ devlink dev flash pci/0000:$bdf file mcupm-verified.img component "mcupm_1"
-
-$ devlink dev flash pci/0000:$bdf file dpm-verified.img component "dpm_1"
-
-$ devlink dev flash pci/0000:$bdf file boot-verified.img component "boot"
-
-$ devlink dev flash pci/0000:$bdf file root.squashfs component "rootfs"
-
-$ devlink dev flash pci/0000:$bdf file modem-verified.img component "md1img"
-
-$ devlink dev flash pci/0000:$bdf file dsp-verified.bin component "md1dsp"
-
-$ devlink dev flash pci/0000:$bdf file OP_OTA.img component "mcf1"
-
-$ devlink dev flash pci/0000:$bdf file OEM_OTA.img component "mcf2"
-
-$ devlink dev flash pci/0000:$bdf file DEV_OTA.img component "mcf3"
-
-Note: component "value" represents the partition type to be programmed.
-
-Regions
-=======
-
-The ``t7xx`` driver supports core dump collection when device encounters
-an exception. When wwan device encounters an exception, a snapshot of device
-internal data will be taken by the driver using fastboot commands.
-
-Following regions are accessed for device internal data.
-
-.. list-table:: Regions implemented
-    :widths: 15 85
-
-    * - Name
-      - Description
-    * - ``mr_dump``
-      - The detailed modem components log are captured in this region
-    * - ``lk_dump``
-      - This region dumps the current snapshot of lk
-
-
-Region commands
-===============
-
-$ devlink region show
-
-
-$ devlink region new mr_dump
-
-$ devlink region read mr_dump snapshot 0 address 0 length $len
-
-$ devlink region del mr_dump snapshot 0
-
-$ devlink region new lk_dump
-
-$ devlink region read lk_dump snapshot 0 address 0 length $len
-
-$ devlink region del lk_dump snapshot 0
-
-Note: $len is actual len to be dumped.
