2019-01-18drm/sun4i: backend: Use explicit fourcc helpers for packed YUV422 checkPaul Kocialkowski
Checking for the number of planes is not sufficient to en ensure that the format is a packed YUV422. Use explicit fourcc helpers for the check instead.

2019-01-18drm/i915: Use b->irq_enable() as predicate for mock engineChris Wilson
Since commit d4ccceb05591 ("drm/i915/icl: Ringbuffer interrupt handling") we have required a mechanism to avoid touching the interrupt hardware for breadcrumbs, superseding our mock interface for selftests. The residual problem (ideas welcome) is in probing the mock ring registers for ring_is_idle. Hmm, maybe we should just install mock handlers for i915->uncore.mmio__write and friends? Only problem being is that we would to truly mock some expected reads. :( References: d4ccceb05591 ("drm/i915/icl: Ringbuffer interrupt handling") Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190118112225.13780-1-chris@chris-wilson.co.uk

2019-01-18drm/i915/breadcrumbs: Drop assertion that we've already enabled irqsChris Wilson
The motivation for introducing the check that we only enable breadcrumb irqs if the device's irq was installed was once upon a time we waited during suspend after disabling interrupts (which was quite slow until the bug was discovered). Since then we have the notion of pinning the breadcrumb irq, broadening it from the sole purpose of user interrupt notification and waiting, and more importantly decoupling it from a very defined time period during which enabling the irq was expected. So stop insisting the irq is installed before we setup our IMR masks, if the IER isn't yet enabled, nothing will happen and we will timeout instead, revealing the lack of irq in the hang debug messages.

2019-01-16drm/tegra: sor: Parse more data from HDA formatThierry Reding
The HDA format data passed to the SOR from the HDA codec contains more information than just the rate and number of channels. Parse all the fields and store them in an internal structure for subsequent use. While at it, also fix an off-by-one error in the number of channels.

2019-01-16drm/tegra: Refactor CEC supportThierry Reding
Most of the CEC support code already lives in the "output" library code. Move registration and unregistration to the library code as well to make use of the same code with HDMI on Tegra210 and later via the SOR.

2019-01-16drm/i915: Pass down rc in intel_encoder->compute_config()Lyude Paul
Something that I completely missed when implementing the new MST VCPI atomic helpers is that with those helpers, there's technically a chance of us having to grab additional modeset locks in ->compute_config() and furthermore, that means we have the potential to hit a normal modeset deadlock. However, because ->compute_config() only returns a bool this means we can't return -EDEADLK when we need to drop locks and try again which means we end up just failing the atomic check permanently. Whoops. So, fix this by modifying ->compute_config() to pass down an actual error code instead of a bool so that the atomic check can be restarted on modeset deadlocks. Thanks to Ville Syrjälä for pointing this out! Changes since v1: * Add some newlines * Return only -EINVAL from hsw_crt_compute_config() * Propogate return code from intel_dp_compute_dsc_params() * Change all of the intel_dp_compute_link_config*() variants * Don't miss if (hdmi_port_clock_valid()) branch in intel_hdmi_compute_config() [Cherry-picked from drm-misc-next to drm-intel-next-queued to fix linux-next & drm-tip conflict, while waiting for proper propagation of the DP MST series that this commit fixes.

Use the new PM-runtime interface to get the accounted suspended time: pm_runtime_suspended_time(). This new interface helps to simplify and cleanup the code that computes __I915_SAMPLE_RC6_ESTIMATED and to remove direct access to internals of PM-runtime.

2019-01-15drm/sun4i: backend: add missing of_node_putsJulia Lawall
The device node iterators perform an of_node_get on each iteration, so a jump out of the loop requires an of_node_put. Remote and port also have augmented reference counts, so drop them on each iteration and at the end of the function, respectively. Remote is only used for the address it contains, not for the contents of that address, so the reference count can be dropped immediately. The semantic patch that fixes the first part of this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @@ expression root,e; local idexpression child; iterator name for_each_child_of_node; @@ for_each_available_child_of_node(root, child) { ... when != of_node_put(child) when != e = child + of_node_put(child); ? break; ... } ... when != child // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com> Link: https://patchwork.freedesktop.org/patch/msgid/1547369264-24831-5-git-send-email-Julia.Lawall@lip6.fr
