OK, thanks! I've just pushed these patches to drm-misc-next with your Ack:

63358e24ee79 drm/panel: panel-simple: Cache the EDID as long as we retain power
31e25395d8b7 drm/panel: panel-simple: Power the panel when reading the EDID
4318ea406e02 drm/panel: panel-simple: Remove extra call:
drm_connector_update_edid_property()
b137406d9679 drm/bridge: ti-sn65dsi86: If refclk, DP AUX can happen
w/out pre-enable
f7a5ee2cd3e2 drm/bridge: ti-sn65dsi86: Code motion of refclk
management functions
9bede63127c6 drm/bridge: ti-sn65dsi86: Use pm_runtime autosuspend
5c4381eeb709 drm/panel: panel-simple: Get rid of hacky HPD chicken-and-egg code
bf73537f411b drm/bridge: ti-sn65dsi86: Break GPIO and MIPI-to-eDP
bridge into sub-drivers
bef236a5206c drm/bridge: ti-sn65dsi86: Move all the chip-related init
to the start
f94eb8a32863 drm/bridge: ti-sn65dsi86: Cleanup managing of drvdata
3636fc25f760 drm/bridge: ti-sn65dsi86: Add local var for "dev" to simplify probe
52d54819c8ae drm/bridge: ti-sn65dsi86: Clean debugfs code
dea2500a820c drm/bridge: ti-sn65dsi86: Use devm to do our runtime_disable
905d66d08d0f drm/bridge: ti-sn65dsi86: More renames in prep for sub-devices
db0036db4851 drm/bridge: ti-sn65dsi86: Rename the main driver data structure

Things not pushed:

[v5,15/20] i2c: i2c-core-of: Fix corner case of finding adapter by node
-> Can't push i2c things

[v5,14/20] drm/bridge: ti-sn65dsi86: Promote the AUX channel to its own sub-dev
-> Won't work without rework. See [1]

[v5,19/20] drm/bridge: ti-sn65dsi86: Don't read EDID blob over DDC
-> Needs Laurent and also patch 14/20 to be resolved.

[v5,20/20] arm64: dts: qcom: Link the panel to the bridge's DDC bus
-> Needs all the rest resolved.

Let me see if I can find a way to work around the AUX channel stuff
and then I'll push a v6 of just what's left.

I seem to recall you mentioning something like this. When I looked at
it in the past I wasn't convinced it would be easy. See my response
[2]. The rough summary is that I didn't think the helpers were happy
with the pm_runtime() model that I'm using. Did I get that wrong?
