drm/amd/amdgpu: Added a quirk for Stoney platform

2017-08-15T18:46:22Z

Added DW_I2S_QUIRK_16BIT_IDX_OVERRIDE quirk for Stoney. Supported format and bus width for I2S controller read from I2S Component Parameter registers. These are ready only registers. For Stoney, I2S Component Parameter registers are programmed to support 32 bit format and 4 bytes bus width only. By setting this quirk,It will override 32 bit format with 16 bit format and 2 bytes as bus width for Stoney. Reviewed-by: Alex Deucher Signed-off-by: Vijendar Mukunda Signed-off-by: Alex Deucher

drm/amdgpu: fix crash in acp_hw_fini

On CZ/ST systems with AZ rather than ACP audio, we need to bail early in hw_fini since there is nothing to do. bug: https://bugs.freedesktop.org/show_bug.cgi?id=98276 Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

drm/amdgpu: rework IP block registration (v2)

2016-10-25T18:38:45Z

This makes it easier to replace specific IP blocks on asics for handling virtual_dce, DAL, etc. and for building IP lists for hw or tables. This also stored the status information in the same structure. v2: split out spelling fix into a separate patch add a function to add IPs to the list Reviewed-by: Christian König Signed-off-by: Alex Deucher

PM / Domains: Allow genpd to power on during system PM phases

2016-06-16T13:01:43Z

If a PM domain is powered off when the first device starts its system PM prepare phase, genpd prevents any further attempts to power on the PM domain during the following system PM phases. Not until the system PM complete phase is finalized for all devices in the PM domain, genpd again allows it to be powered on. This behaviour needs to be changed, as a subsystem/driver for a device in the same PM domain may still need to be able to serve requests in some of the system PM phases. Accordingly, it may need to runtime resume its device and thus also request the corresponding PM domain to be powered on. To deal with these scenarios, let's make the device operational in the system PM prepare phase by runtime resuming it, no matter if the PM domain is powered on or off. Changing this also enables us to remove genpd's suspend_power_off flag, as it's being used to track this condition. Additionally, we must allow the PM domain to be powered on via runtime PM during the system PM phases. This change also requires a fix in the AMD ACP (Audio CoProcessor) drm driver. It registers a genpd to model the ACP as a PM domain, but unfortunately it's also abuses genpd's "internal" suspend_power_off flag to deal with a corner case at system PM resume. More precisely, the so called SMU block powers on the ACP at system PM resume, unconditionally if it's being used or not. This may lead to that genpd's internal status of the power state, may not correctly reflect the power state of the HW after a system PM resume. Because of changing the behaviour of genpd, by runtime resuming devices in the prepare phase, the AMD ACP drm driver no longer have to deal with this corner case. So let's just drop the related code in this driver. Signed-off-by: Ulf Hansson Reviewed-by: Kevin Hilman Acked-by: Maruthi Bayyavarapu Signed-off-by: Rafael J. Wysocki
