While the DP specification isn't entirely clear on if this should be allowed or not, some branch devices report having downstream ports present while also reporting a downstream port count of 0. So to avoid breaking those devices, we need to handle this in drm_dp_read_downstream_info(). So, to do this we assume there's no downstream port info when the downstream port count is 0.

It doesn't make sense to go out to the bus and read the EDID over and over again. Let's cache it and throw away the cache when we turn power off from the panel. Autosuspend means that even if there are several calls to read the EDID before we officially turn the power on then we should get good use out of this cache.

I don't believe that it ever makes sense to read the EDID when a panel is not powered and the powering on of the panel is the job of prepare(). Let's make sure that this happens before we try to read the EDID. We use the pm_runtime functions directly rather than directly calling the normal prepare() function because the pm_runtime functions are definitely refcounted whereas it's less clear if the prepare() one is. NOTE: I'm not 100% sure how EDID reading was working for folks in the past, but I can only assume that it was failing on the initial attempt and then working only later. This patch, presumably, will fix that. If some panel out there really can read the EDID without powering up and it's a big advantage to preserve the old behavior we can add a per-panel flag. It appears that providing the DDC bus to the panel in the past was somewhat uncommon in any case.

Let's reorganize how we init and turn on the reference clock in the code to allow us to turn it on early (even before pre_enable()) so that we can read the EDID early. This is handy for eDP because: - We always assume that a panel is there. - Once we report that a panel is there we get asked to read the EDID. - Pre-enable isn't called until we know what pixel clock we want to use and we're ready to turn everything on. That's _after_ we get asked to read the EDID. NOTE: the above only works out OK if we "refclk" is provided. Though I don't have access to any hardware that uses ti-sn65dsi86 and _doesn't_ provide a "refclk", I believe that we'll have trouble reading the EDID at bootup in that case. Specifically I believe that if there's no "refclk" we need the MIPI source clock to be active before we can successfully read the EDID. My evidence here is that, in testing, I couldn't read the EDID until I turned on the DPPLL in the bridge chip and that the DPPLL needs the input clock to be active. Since this is hard to support, let's punt trying to handle this case if there's no "refclk". In that case we'll enable comms in pre_enable() like we always did. I don't believe there are any users of the ti-sn65dsi86 bridge chip that _don't_ use "refclk". The bridge chip is _very_ inflexible in that mode. The only time I've seen that mode used was for some really early prototype hardware that was thrown in the e-waste bin years ago when we realized how inflexible it was. Even if someone is using the bridge chip without the "refclk" they're in no worse shape than they were before the (fairly recent) commit 58074b08 ("drm/bridge: ti-sn65dsi86: Read EDID blob over DDC").

When I added support for the hpd-gpio to simple-panel in commit 48834e60 ("drm/panel-simple: Support hpd-gpios for delaying prepare()"), I added a special case to handle a circular dependency I was running into on the ti-sn65dsi86 bridge chip. On my board the hpd-gpio is actually provided by the bridge chip. That was causing some circular dependency problems that I had to work around by getting the hpd-gpio late. I've now reorganized the ti-sn65dsi86 bridge chip driver to be a collection of sub-drivers. Now the GPIO part can probe separately and that breaks the chain.

Let's use the newly minted aux bus to break up the driver into sub drivers. We're not doing a full breakup here: all the code is still in the same file and remains largely untouched. The big goal here of using sub-drivers is to allow part of our code to finish probing even if some other code needs to defer. This can solve some chicken-and-egg problems. Specifically: - In commit 48834e60 ("drm/panel-simple: Support hpd-gpios for delaying prepare()") we had to add a bit of a hack to simpel-panel to support HPD showing up late. We can get rid of that hack now since the GPIO part of our driver can finish probing early. - We have a desire to expose our DDC bus to simple-panel (and perhaps to a backlight driver?). That will end up with the same chicken-and-egg problem. A future patch to move this to a sub-driver will fix it. - If/when we support the PWM functionality present in the bridge chip for a backlight we'll end up with another chicken-and-egg problem. If we allow the PWM to be a sub-driver too then it solves this problem.

Let's cleanup the debugfs code to: - Check for errors. - Use devm to manage freeing, which also means we don't need to store a pointer in our structure.

There's no devm_runtime_enable(), but it's easy to use devm_add_action_or_reset() and means we don't need to worry about the disable in our remove() routine or in error paths. No functional changes intended by this change.

Like the previous patch ("drm/bridge: ti-sn65dsi86: Rename the main driver data structure") this is just a no-op rename in preparation for splitting the driver up a bit. Here I've attempted to rename functions / structures making sure that anything applicable to the whole chip (instead of just the MIPI to eDP bridge part) included "sn65dsi86" somewhere in the name instead of just "ti_sn_bridge".

In preparation for splitting this driver into sub-drivers, let's rename the main data structure so it's clear that it's holding data for the whole device and not just the MIPI-eDP bridge part.

The field pdev in struct drm_device is unused. Remove it. The value can be obtained by upcasting from the structure's dev field.
