2021-04-20drm/panel: panel-simple: Use runtime pm to avoid excessive unprepare / prepareDouglas Anderson
Unpreparing and re-preparing a panel can be a really heavy operation. Panels datasheets often specify something on the order of 500ms as the delay you should insert after turning off the panel before turning it on again. In addition, turning on a panel can have delays on the order of 100ms - 200ms before the panel will assert HPD (AKA "panel ready"). The above means that we should avoid turning a panel off if we're going to turn it on again shortly. The above becomes a problem when we want to read the EDID of a panel. The way that ordering works is that userspace wants to read the EDID of the panel _before_ fully enabling it so that it can set the initial mode correctly. However, we can't read the EDID until we power it up. This leads to code that does this dance (like ps8640_bridge_get_edid()): 1. When userspace requests EDID / the panel modes (through an ioctl), we power on the panel just enough to read the EDID and then power it off. 2. Userspace then turns the panel on. There's likely not much time between step #1 and #2 and so we want to avoid powering the panel off and on again between those two steps. Let's use Runtime PM to help us. We'll move the existing prepare() and unprepare() to be runtime resume() and runtime suspend(). Now when we want to prepare() or unprepare() we just increment or decrement the refcount. We'll default to a 1 second autosuspend delay which seems sane given the typical delays we see for panels. A few notes: - It seems the existing unprepare() and prepare() are defined to be no-ops if called extra times. We'll preserve that behavior but may try to remove it in a future patch. - This is a slight change in the ABI of simple panel. If something was absolutely relying on the unprepare() to happen instantly that simply won't be the case anymore. I'm not aware of anyone relying on that behavior, but if there is someone then we'll need to figure out how to enable (or disable) this new delayed behavior selectively. - In order for this to work we now have a hard dependency on "PM". From memory this is a legit thing to assume these days and we don't have to find some fallback to keep working if someone wants to build their system without "PM".

2021-04-19drm/bridge/sii8620: fix dependency on extconRobert Foss
The DRM_SIL_SII8620 kconfig has a weak `imply` dependency on EXTCON, which causes issues when sii8620 is built as a builtin and EXTCON is built as a module. The symptoms are 'undefined reference' errors caused by the symbols in EXTCON not being available to the sii8620 driver.

Since commit 890880ddfdbe256083170866e49c87618b706ac7 Author: Paul Kocialkowski <paul.kocialkowski@bootlin.com> Date: Fri Jan 4 09:56:10 2019 +0100 drm: Auto-set allow_fb_modifiers when given modifiers at plane init this is done automatically as part of plane init, if drivers set the modifier list correctly. Which is the case here. It was slightly inconsistently though, since planes with only linear modifier support haven't listed that explicitly. Fix that, and cc: stable to allow userspace to rely on this. Again don't backport further than where Paul's patch got added.
