+=======================
+ dGPU firmware flashing
+=======================
+
+IFWI
+----
+Flashing the dGPU integrated firmware image (IFWI) is supported by GPUs that
+use the PSP to orchestrate the update (Navi3x or newer GPUs).
+For supported GPUs, `amdgpu` will export a series of sysfs files that can be
+used for the flash process.
+
+The IFWI flash process is:
+
+1. Ensure the IFWI image is intended for the dGPU on the system.
+2. "Write" the IFWI image to the sysfs file `psp_vbflash`. This will stage the IFWI in memory.
+3. "Read" from the `psp_vbflash` sysfs file to initiate the flash process.
+4. Poll the `psp_vbflash_status` sysfs file to determine when the flash process completes.
+
+USB-C PD F/W
+------------
+On GPUs that support flashing an updated USB-C PD firmware image, the process
+is done using the `usbc_pd_fw` sysfs file.
+
+* Reading the file will provide the current firmware version.
+* Writing the name of a firmware payload stored in `/lib/firmware/amdgpu` to the sysfs file will initiate the flash process.
+
+The firmware payload stored in `/lib/firmware/amdgpu` can be named any name
+as long as it doesn't conflict with other existing binaries that are used by
+`amdgpu`.

+In the patch ("drm/panel: Check for already prepared/enabled in drm_panel")
+we've moved this check to the core. Now we can most definitely remove the
+check from the individual panels and save a pile of code.
+
+In adition to removing the check from the individual panels, it is believed
+that even the core shouldn't need this check and that should be considered
+an error if other code ever relies on this check. The check in the core
+currently prints a warning whenever something is relying on this check with
+dev_warn(). After a little while, we likely want to promote this to a
+WARN(1) to help encourage folks not to rely on this behavior.
