The current suspend resume implementation is assuming register values are kept when entering suspend, which is no longer the case with the suspend-to-RAM on the sama5d2. While at it, switch to the generic infrastructure to enter suspend mode (drm_atomic_helper_suspend/resume()).

On vblank instant-off systems, we can get into a situation where the cost of enabling and disabling the vblank IRQ around a drmWaitVblank query dominates. And with the advent of even deeper hardware sleep state, touching registers becomes ever more expensive. However, we know that if the user wants the current vblank counter, they are also very likely to immediately queue a vblank wait and so we can keep the interrupt around and only turn it off if we have no further vblank requests queued within the interrupt interval. After vblank event delivery, this patch adds a shadow of one vblank where the interrupt is kept alive for the user to query and queue another vblank event. Similarly, if the user is using blocking drmWaitVblanks, the interrupt will be disabled on the IRQ following the wait completion. However, if the user is simply querying the current vblank counter and timestamp, the interrupt will be disabled after every IRQ and the user will enabled it again on the first query following the IRQ. v2: Mario Kleiner - After testing this, one more thing that would make sense is to move the disable block at the end of drm_handle_vblank() instead of at the top. Turns out that if high precision timestaming is disabled or doesn't work for some reason (as can be simulated by echo 0 > /sys/module/drm/parameters/timestamp_precision_usec), then with your delayed disable code at its current place, the vblank counter won't increment anymore at all for instant queries, ie. with your other "instant query" patches. Clients which repeatedly query the counter and wait for it to progress will simply hang, spinning in an endless query loop. There's that comment in vblank_disable_and_save: "* Skip this step if there isn't any high precision timestamp * available. In that case we can't account for this and just * hope for the best. */ With the disable happening after leading edge of vblank (== hw counter increment already happened) but before the vblank counter/timestamp handling in drm_handle_vblank, that step is needed to keep the counter progressing, so skipping it is bad. Now without high precision timestamping support, a kms driver must not set dev->vblank_disable_immediate = true, as this would cause problems for clients, so this shouldn't matter, but it would be good to still make this robust against a future kms driver which might have unreliable high precision timestamping, e.g., high precision timestamping that intermittently doesn't work. v3: Patch before coffee needs extra coffee.

Sadly there's only 1 driver which can use it, everyone else is special for some reason: - gma500 has a horrible runtime PM ioctl wrapper that probably doesn't really work but meh. - i915 needs special compat_ioctl handler because regrets. - arcgpu needs to fixup the pgprot because (no idea why it can't do that in the fault handler like everyone else). - tegra does even worse stuff with pgprot - udl does something with vm_flags too ... - cma helpers, etnaviv, mtk, msm, rockchip, omap all implement some variation on prefaulting. - exynos is exynos, I got lost in the midlayers. - vc4 has to reinvent half of cma helpers because those are too much midlayer, plus vm_flags dances. - vgem also seems unhappy with the default vm_flags. So pretty sad divergence and I'm sure we could do better, but not really an idea. Oh well, maybe this macro here helps to encourage more consistency at least going forward.

Well, mostly drm_file.h, and clean up all related things: - I didnt' figure out the difference between preclose and postclose. The existing explanation in drm-internals.rst didn't convince me, since it's also really outdated - we clean up pending DRM events in the core nowadays. I put a FIXME in for the future. - Another FIXME is to have a macro for default fops. - Lots of links all around, main areas are to tie the overview in drm_file.c more into the callbacks in struct drm_device, and the other is to link render/primary node code to the right sections in drm-uapi.rst. - Also moved the open/close stuff to drm_drv.h from drm-internals.rst, seems like the better place for that information. Since that section was rather outdated this amounted to full-on rewrite. A big missing piece here is some overview graph, but I think better to wait with that one until drm_device and drm_driver are also fully documented. v2: Nits from Sean.

We might as well dump the drm_file pointer, that's about as useful a cookie as the pid. Noticed while typing docs for drm_file and friends. Since the only consumer of this is the tracepoints I think we can safely change this - those tracepoints should not be uapi relevant at all.

Also note that the nouveau code setting it is entirely pointless: Since this isn't a vblank event, it will never hit the vblank tracepoints.

The Synopsys Designware HDMI TX Controller does not enforce register access on platforms instanciating it. The current driver supports two different types of memory-mapped flat register access, but in order to support the Amlogic Meson SoCs integration, and provide a more generic way to handle all sorts of register mapping, switch the register access to use the regmap infrastructure. In the case of registers that are not flat memory-mapped or do not conform to the current driver implementation, a regmap struct can be given in the plat_data and be used at probe or bind. Since the AHB audio driver is only available with direct memory access, only allow the I2S audio driver to be registered is directly memory-mapped.

The HDMI TX controller support different PHYs whose programming interface can vary significantly, especially with vendor PHYs that are not provided by Synopsys. To support them, create a PHY operation structure that can be provided by the platform glue layer. The existing PHY handling code (limited to Synopsys PHY support) is refactored into a set of default PHY operations that are used automatically when the platform glue doesn't provide its own operations.

When powering the PHY up we need to wait for the PLL to lock. This is done by polling the TX_PHY_LOCK bit in the HDMI_PHY_STAT0 register (interrupt-based wait could be implemented as well but is likely overkill). The bit is asserted when the PLL locks, but the current code incorrectly waits for the bit to be deasserted. Fix it, and while at it, replace the udelay() with a sleep as the code never runs in non-sleepable context. To be consistent with the power down implementation move the poll loop to the power off function.

The PHY requires us to wait for the PHY to switch to low power mode after deasserting TXPWRON and before asserting PDDQ in the power down sequence, otherwise power down will fail. The PHY power down can be monitored though the TX_READY bit, available through I2C in the PHY registers, or the TX_PHY_LOCK bit, available through the HDMI TX registers. As the two are equivalent, let's pick the easier solution of polling the TX_PHY_LOCK bit. The power down code is currently duplicated in multiple places. To avoid spreading multiple calls to a TX_PHY_LOCK poll function, we have to refactor the power down code and group it all in a single function. Tests showed that one poll iteration was enough for TX_PHY_LOCK to become low, without requiring any additional delay. Retrying the read five times with a 1ms to 2ms delay between each attempt should thus be more than enough.
