To let the probe function bail early if any of the resources is unavailable, move resource allocattion from kms_init directly to the probe callback. While we are at it, replace irq_of_parse_and_map() with platform_get_irq(). This also drops devm_iounmap() calls. It is too early to have them _dpu_kms_hw_destroy() (or it will break if for some reason DPU device is rebound into the composite device) and it doesn't make sense to have them in dpu_dev_remove (as everything will be torn down by the devres anyway after the device is unbound from the driver).

When opp-supported-hw is present under an OPP node, but no form of opp_set_supported_hw() has been called, that OPP is ignored by the API and marked as unsupported. Before Commit c928a05e ("drm/msm/adreno: Move speedbin mapping to device table"), an unknown speedbin would result in marking all OPPs as available, but it's better to avoid potentially overclocking the silicon - the GMU will simply refuse to power up the chip. Currently, the Adreno speedbin code does just that (AND returns an invalid error, (int)UINT_MAX). Fix that by defaulting to speedbin 0 (which is conveniently always bound to fuseval == 0).

Some GPUs - particularly A7xx ones - are really really stubborn and sometimes take a longer-than-expected time to finish unhalting GBIF. Note that this is not caused by the request a few lines above. Poll for the unhalt ack to make sure we're not trying to write bits to an essentially dead GPU that can't receive data on its end of the bus. Failing to do this will result in inexplicable GMU timeouts or worse. This is a rather ugly hack which introduces a whole lot of latency.

A740 builds upon the A730 IP, shuffling some values and registers around. More differences will appear when things like BCL are implemented. adreno_is_a740_family is added in preparation for more A7xx GPUs, the logic checks will be valid resulting in smaller diffs.

The QMP mailbox expects to be notified of the ACD (Adaptive Clock Distribution) state. Get a handle to the mailbox at probe time and poke it at GMU resume. Since we don't fully support ACD yet, hardcode the message to "val: 0" (state = disabled).

A7xx GPUs are - from kernel's POV anyway - basically another generation of A6xx. They build upon the A650/A660_family advancements, skipping some writes (presumably more values are preset correctly on reset), adding some new ones and changing others. One notable difference is the introduction of a second shadow, called BV. To handle this with the current code, allocate it right after the current RPTR shadow. BV handling and .submit are mostly based on Jonathan Marek's work. All A7xx GPUs are assumed to have a GMU. A702 is not an A7xx-class GPU, it's a weird forked A610.

The GMU on the A7xx series is pretty much the same as on the A6xx parts. It's now "smarter", needs a bit less register writes and controls more things (like inter-frame power collapse) mostly internally (instead of us having to write to G[PM]U_[CG]X registers from APPS) The only difference worth mentioning is the now-required DEMET clock, which is strictly required for things like asserting reset lines, not turning it on results in GMU not being fully functional (all OOB requests would fail and HFI would hang after the first submitted OOB). Describe the A730 and A740 GMU. Reviewed-by:

As the INTF is fixed at the encoder creation time, we can move the check whether INTF supports tearchck to dpu_encoder_phys_cmd_init(). This function can return an error if INTF doesn't have required feature. Performing this check in dpu_encoder_phys_cmd_tearcheck_config() is less useful, as this function returns void. Signed-off-by:

The DP CTS test for EDID last block checksum expects the checksum for the last block, invalid or not. Skip the validity check. For the most part (*), the EDIDs returned by drm_get_edid() will be valid anyway, and there's the CTS workaround to get the checksum for completely invalid EDIDs. See commit 7948fe12 ("drm/msm/dp: return correct edid checksum after corrupted edid checksum read"). This lets us remove one user of drm_edid_block_valid() with hopes the function can be removed altogether in the future. (*) drm_get_edid() ignores checksum errors on CTA extensions.

The function dp_link_parse_sink_count() is really just drm_dp_read_sink_count(). It debug prints out the bit for content protection (DP_SINK_CP_READY), but that is not useful beyond debug because 'link->dp_link.sink_count' is overwritten to only contain the sink_count in this same function.
