a55c8ff252 drm/msm/mdss: Handle the reg bus ICC path 
Apart from the already handled data bus (MAS_MDP_Pn<->DDR), there's
another path that needs to be handled to ensure MDSS functions properly,
namely the "reg bus", a.k.a the CPU-MDSS interconnect.

Gating that path may have a variety of effects, from none to otherwise
inexplicable DSI timeouts.

Provide a way for MDSS driver to vote on this bus.

A note regarding vote values. Newer platforms have corresponding
bandwidth values in the vendor DT files. For the older platforms there
was a static vote in the mdss_mdp and rotator drivers. I choose to be
conservative here and choose this value as a default.

fabaf17632 drm/msm/mdss: Rename path references to mdp_path 
The DPU1 driver needs to handle all MDPn<->DDR paths, as well as
CPU<->SLAVE_DISPLAY_CFG. The former ones share how their values are
calculated, but the latter one has static predefines spanning all SoCs.

In preparation for supporting the CPU<->SLAVE_DISPLAY_CFG path, rename

This reverts commit 4b64167042.

Although the Solid Fill planes patchset got all reviews and
acknowledgements, it doesn't fulfill requirements for the new uABI. It
has neither corresponding open-source userspace implementation nor the
IGT tests coverage. Reverting this patchset until userspace obligations

d0b3c318e0 drm/bridge: migrate bridge_chains to per-encoder file 
Instead of having a single file with all bridge chains, list bridges
under a corresponding per-encoder debugfs directory.

While we are at it, also slightly improve the formatting of the bridge
data: split a single line entry into multiple lines, include the symbol
name of the bridge funcs and add the textual representation of the
bridge ops.

Example of the listing:

$ cat /sys/kernel/debug/dri/0/encoder-0/bridges
bridge[0]: dsi_mgr_bridge_funcs
	type: [0] Unknown
	ops: [0]
bridge[1]: lt9611uxc_bridge_funcs

The i2c_master_send/recv() functions return negative error codes or the
number of bytes that were able to be sent/received.  This code has
two problems.  1)  Instead of checking if all the bytes were sent or
received, it checks that at least one byte was sent or received.
2) If there was a partial send/receive then we should return a negative
error code but this code returns success.

the second operand an actual bool result, const correctness can be preserved
