Pull ARM driver updates from Arnd Bergmann:
 "These are the usual updates for SoC specific device drivers and
  related subsystems that don't have their own top-level maintainers:

   - ARM SCMI/SCPI updates to allow pluggable transport layers

   - TEE subsystem cleanups

   - A new driver for the Amlogic secure power domain controller

   - Various driver updates for the NXP Layerscape DPAA2, NXP i.MX SCU
     and TI OMAP2+ sysc drivers.

   - Qualcomm SoC driver updates, including a new library module for
     "protection domain" notifications

   - Lots of smaller bugfixes and cleanups in other drivers"

drm: Remove drm_fb_helper add, add all and remove connector calls

2020-03-06T13:19:58+00:00

drm_fb_helper_{add,remove}_one_connector() and
drm_fb_helper_single_add_all_connectors() are dummy functions now
and serve no purpose. Hence remove their calls.

This is the preparatory step for removing the
drm_fb_helper_{add,remove}_one_connector() functions from
drm_fb_helper.h

This removal is done using below sementic patch and unused variable
compilation warnings are fixed manually.

drm/omap: Prepare DSS for probing without legacy platform data

2020-02-26T18:02:19+00:00

In order to probe display subsystem (DSS) components with ti-sysc
interconnect target module without legacy platform data and using
devicetree, we need to update dss probing a bit.

In the device tree, we will be defining the data also for the interconnect
target modules as DSS really is a private interconnect. There is some
information about that in 4460 TRM in "Figure 10-3. DSS Integration" for
example where it mentions "32-bit interconnect (SLX)".

The changes we need to make are:

1. Parse also device tree subnodes for the compatible property fixup

2. Update the component code to consider device tree subnodes

drm/omap: sdi: Register a drm_bridge

2020-02-26T11:32:09+00:00

In order to integrate with a chain of drm_bridge, the internal SDI
output has to expose its operations through the drm_bridge API.
Register a bridge at initialisation time to do so and remove the
omap_dss_device operations that are now unused.
