2020-04-09drm/dp_mst: Print errors on ACT timeoutsLyude Paul
Although it's not unexpected for drm_dp_check_act_status() to fail due to DPCD read failures (as the hub may have just been unplugged suddenly), timeouts are a bit more worrying as they either mean we need a longer timeout value, or we aren't setting up payload allocations properly. So, let's start printing errors on timeouts.

2020-04-09drm/dp_mst: Increase ACT retry timeout to 3sLyude Paul
Currently we only poll for an ACT up to 30 times, with a busy-wait delay of 100µs between each attempt - giving us a timeout of 2900µs. While this might seem sensible, it would appear that in certain scenarios it can take dramatically longer then that for us to receive an ACT. On one of the EVGA MST hubs that I have available, I observed said hub sometimes taking longer then a second before signalling the ACT. These delays mostly seem to occur when previous sideband messages we've sent are NAKd by the hub, however it wouldn't be particularly surprising if it's possible to reproduce times like this simply by introducing branch devices with large LCTs since payload allocations have to take effect on every downstream device up to the payload's target. So, instead of just retrying 30 times we poll for the ACT for up to 3ms, and additionally use usleep_range() to avoid a very long and rude busy-wait. Note that the previous retry count of 30 appears to have been arbitrarily chosen, as I can't find any mention of a recommended timeout or retry count for ACTs in the DisplayPort 2.0 specification. This also goes for the range we were previously using for udelay(), although I suspect that was just copied from the recommended delay for link training on SST devices.

2020-04-09drm/bridge: analogix_dp: Split bind() into probe() and real bind()Marek Szyprowski
Analogix_dp driver acquires all its resources in the ->bind() callback, what is a bit against the component driver based approach, where the driver initialization is split into a probe(), where all resources are gathered, and a bind(), where all objects are created and a compound driver is initialized. Extract all the resource related operations to analogix_dp_probe() and analogix_dp_remove(), then call them before/after registration of the device components from the main Exynos DP and Rockchip DP drivers. Also move the plat_data initialization to the probe() to make it available for the analogix_dp_probe() function. This fixes the multiple calls to the bind() of the DRM compound driver when the DP PHY driver is not yet loaded/probed: [drm] Exynos DRM: using 14400000.fimd device for DMA mapping operations exynos-drm exynos-drm: bound 14400000.fimd (ops fimd_component_ops [exynosdrm]) exynos-drm exynos-drm: bound 14450000.mixer (ops mixer_component_ops [exynosdrm]) exynos-dp 145b0000.dp-controller: no DP phy configured exynos-drm exynos-drm: failed to bind 145b0000.dp-controller (ops exynos_dp_ops [exynosdrm]): -517 exynos-drm exynos-drm: master bind failed: -517 ...

This patch process phy compliance request by programming requested vswing, pre-emphasis and test pattern. v1: Initial patch. v2: Fixes added during testing with test-scope. (Khaled/Clint/Manasi) - pipe used as argument during registers programming instead of port. - TRANS_CONF must be disable/enable as well during ddi disable/enable. - harcoded PLTPAT 80 bit custom pattern as the DPR-100 does not set it in the sink’s DPCDs - TRANS_DDI_FUNC_CTL DDI_Select (Bits 27:30) need to reset/set during disable/enable. v3: used macros instead of numbers and some cosmetic changes.

2020-04-07drm/dp_mst: Remove drm_dp_mst_has_audio()Lyude Paul
Drive-by fix I noticed the other day - drm_dp_mst_has_audio() only ever made sense back when we still had to validate ports before accessing them in order to (attempt to) avoid NULL dereferences. Since we have proper reference counting that guarantees we always can safely access the MST port, there's no use in keeping this function around as all it does is validate the port pointer before checking the audio status. Note - drm_dp_mst_port->has_audio is technically protected by drm_device->mode_config.connection_mutex, since it's only ever updated from drm_dp_mst_get_edid(). Additionally, we change the declaration for port in struct intel_connector to be properly typed, so we can directly access it.

2020-04-07drm/i915/dp_mst: Cast intel_connector->port as drm_dp_mst_portLyude Paul
The only reason for having this cast as void * before was because we originally needed to use drm_dp_mst_get_port_validated() and friends in order to (attempt to) safely access MST ports. However, we've since improved how reference counting works with ports and mstbs such that we can now rely on drm_dp_mst_port structs remaining in memory for as long as the driver needs. This means we don't really need to cast this as void* anymore, and can just access the struct directly. We'll also need this for the next commit, so that we can remove drm_dp_mst_port_has_audio().
