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". Signed-off-by:

The clock framework makes it simple to deal with an optional clock. You can call clk_get_optional() and if the clock isn't specified it'll just return NULL without complaint. It's valid to pass NULL to enable/disable/prepare/unprepare. Let's make use of this to simplify things a tiny bit. Signed-off-by:

This adds DW-HDMI driver a glue option to disable loading of the CEC sub-driver. On some SoCs, the CEC functionality is enabled in the IP config bits, but the CEC bus is non-functional like on Amlogic SoCs, where the CEC config bit is set but the DW-HDMI CEC signal is not connected to a physical pin, leading to some confusion when the DW-HDMI CEC controller can't communicate on the bus.

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.
