Configuring counters from the userspace require the kernel to handle some
logic related to performance counters. Basically, it has to find a free
slot to assign a counter, to handle extra counting modes like B4/B6 and it
must return and error when it can't configure a counter.
In my opinion, the kernel should not handle all of that logic but it
should only write the configuration sent by the userspace without
checking anything. In other words, it should overwrite the configuration
even if it's already counting and do not return any errors.
This patch allows the userspace to configure a domain instead of
separate counters. This has the advantage to move all of the logic to
the userspace.

Here are some development updates for the Synopsis Designware HDMI driver,
which clean up some of the code, and start preparing to add audio support
to the driver. This series of patches are based on a couple of dependent
commits from the ALSA tree.
Briefly, the updates are:
- move comments which should have moved with the phy values to the IMX
part of the driver.
- clean up the phy configuration: to all lookups before starting to
program the phy.
- clean up the HDMI clock regenerator code
- use the drm_hdmi_avi_infoframe_from_display_mode() helper which allows
the code to be subsequently simplified
- remove the unused 'regmap' pointer in struct dw_hdmi
- use the bridge drm device rather than the connector (we're the bridge
code)
- remove private hsync/vsync/interlaced flags, getting them from the
DRM mode structure instead.
- implement interface functions to support audio - setting the audio
sample rate, and enabling the audio clocks.
- removal of broken pixel repetition support
- cleanup DVI vs HDMI sink handling
- enable audio only if connected device supports audio
- avoid double-enabling bridge in the sink path (once in mode_set, and
again in commit)
- rename mis-named dw_hdmi_phy_enable_power()
- fix bridge enable/disable handing, so a plug-in event doesn't
reconfigure the bridge if DRM has disabled the output
- fix from Vladimir Zapolskiy for the I2CM_ADDRESS macro name
These are primerily preparitory patches for the AHB audio driver and
the I2S audio driver (from Rockchip) for this IP.

DRM - radeon: Don't link train DisplayPort on HPD until we get the dpcd
to amdgpu.
Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
Cc: stable@vger.kernel.org
Most of the time this isn't an issue since hotplugging an adaptor will
trigger a crtc mode change which in turn, causes the driver to probe
every DisplayPort for a dpcd. However, in cases where hotplugging
doesn't cause a mode change (specifically when one unplugs a monitor
from a DisplayPort connector, then plugs that same monitor back in
seconds later on the same port without any other monitors connected), we
never probe for the dpcd before starting the initial link training. What
happens from there looks like this:
- GPU has only one monitor connected. It's connected via
DisplayPort, and does not go through an adaptor of any sort.
- User unplugs DisplayPort connector from GPU.
- Change in HPD is detected by the driver, we probe every
DisplayPort for a possible connection.
- Probe the port the user originally had the monitor connected
on for it's dpcd. This fails, and we clear the first (and only
the first) byte of the dpcd to indicate we no longer have a
dpcd for this port.
- User plugs the previously disconnected monitor back into the
same DisplayPort.
- radeon_connector_hotplug() is called before everyone else,
and tries to handle the link training. Since only the first
byte of the dpcd is zeroed, the driver is able to complete
link training but does so against the wrong dpcd, causing it
to initialize the link with the wrong settings.
- Display stays blank (usually), dpcd is probed after the
initial link training, and the driver prints no obvious
messages to the log.
In theory, since only one byte of the dpcd is chopped off (specifically,
the byte that contains the revision information for DisplayPort), it's
not entirely impossible that this bug may not show on certain monitors.
For instance, the only reason this bug was visible on my ASUS PB238
monitor was due to the fact that this monitor using the enhanced framing
symbol sequence, the flag for which is ignored if the radeon driver
thinks that the DisplayPort version is below 1.1.

Instead the valid token "DCU" is used to tag the register names and
function names.
The Display Controller Unit (DCU) module is a system master that
fetches graphics stored in internal or external memory and displays
them on a TFT LCD panel. A wide range of panel sizes is supported
and the timing of the interface signals is highly configurable.
Graphics are read directly from memory and then blended in real-time,
which allows for dynamic content creation with minimal CPU
intervention.
The features:
(1) Full RGB888 output to TFT LCD panel.
(2) Blending of each pixel using up to 4 source layers
dependent
on size of panel.
(3) Each graphic layer can be placed with one pixel resolution
in either axis.
(4) Each graphic layer support RGB565 and RGB888 direct colors
without alpha channel and BGRA8888 BGRA4444 ARGB1555 direct
colors
with an alpha channel and YUV422 format.
(5) Each graphic layer support alpha blending with 8-bit
resolution.
This is a simplified version, only one primary plane, one
framebuffer, one crtc, one connector and one encoder for TFT
LCD panel.

drm/i915: Allow parsing of variable size child device entries from VBT
That commit is not valid for v4.2, however it will be valid for v4.3. It
was simply queued too early.
The referenced regressing commit is just fine until the size of struct
common_child_dev_config changes, and that won't happen until
v4.3. Indeed, the expected size checks here rely on the increased size
of the struct, breaking new platforms.

The dw_hdmi enable/disable handling is particularly weak in several
regards:
* The hotplug interrupt could call hdmi_poweron() or hdmi_poweroff()
while DRM is setting a mode, which could race with a mode being set.
* Hotplug will always re-enable the phy whenever it detects an active
hotplug signal, even if DRM has disabled the output.
Resolve all of these by introducing a mutex to prevent races, and a
state-tracking bool so we know whether DRM wishes the output to be
enabled. We choose to use our own mutex rather than ->struct_mutex
so that we can still process interrupts in a timely fashion.

dw_hdmi_phy_enable_power() is not about enabling and disabling power.
It is about allowing or preventing power-down mode being entered - the
register is documented as "Power-down enable (active low 0b)."
This can be seen as the bit has no effect when the HDMI phy is
operational on iMX6 hardware.
Rename the function to dw_hdmi_phy_enable_powerdown() to reflect the
documentation, make it take a bool for the 'enable' argument, and invert
the value to be written.

On a mode set, DRM makes the following sequence of calls:
* for_each_encoder
* bridge mode_fixup
* encoder mode_fixup
* crtc mode_fixup
* for_each_encoder
* bridge disable
* encoder prepare
* bridge post_disable
* disable unused encoders
* crtc prepare
* crtc mode_set
* for_each_encoder
* encoder mode_set
* bridge mode_set
* crtc commit
* for_each_encoder
* bridge pre_enable
* encoder commit
* bridge enable
dw_hdmi enables the HDMI output in both the bridge mode_set() and also
the bridge enable() step. This is duplicated work - we can avoid the
setup in mode_set() and just do it in the enable() stage. This
simplifies the code a little.

The FSL kernel detects the HDMI vendor id, and uses this to set
hdmi->edid_cfg.hdmi_cap, which is then used to set mdvi appropriately,
rather than detecting whether we are outputting a CEA mode. Update
the dw_hdmi code to use this logic, but lets eliminate the mdvi
variable, prefering the more verbose "hdmi->sink_is_hdmi" instead.
Use the generic drm_detect_hdmi_monitor() to detect a HDMI sink.

As mentioned in the previous commit, the dw-hdmi driver does not support
pixel doubled modes at present; it does not configure the PLL correctly
for these modes. Therefore, filter out the double-clocked modes as we
presently are unable to support them.

dw_hdmi sets a pixel repetition factor of 1 for VICs 10-15, 25-30 and
35-38. However, DRM uses their native resolutions in its timing
information. For example, VIC 14 can be 1440x480 with no repetition,
or 720x480 with one pixel repetition. As DRM uses 1440 pixels per line
for this video mode, we need no pixel repetition.
In any case, pixel repetition appears broken in dw_hdmi.

iMX6 devices suffer from an errata (ERR005174) where the audio FIFO can
be emptied while it is partially full, resulting in misalignment of the
audio samples.
To prevent this, the errata workaround recommends writing N as zero
until the audio FIFO has been loaded by DMA. Writing N=0 prevents the
HDMI bridge from reading from the audio FIFO, effectively disabling
audio.
This means we need to provide the audio driver with a pair of functions
to enable/disable audio. These are dw_hdmi_audio_enable() and
dw_hdmi_audio_disable().
A spinlock is introduced to ensure that setting the CTS/N values can't
race, ensuring that the audio driver calling the enable/disable
functions (which are called in an atomic context) can't race with a
modeset.

The phy configuration is dependent on the SoC, and we look up values for
some of the registers in SoC specific data. However, we had partially
programmed the phy before we had successfully looked up the clock rate.
Also, we were only checking that we had a valid configuration for the
currctrl register.
Move all these lookups to the start of this function instead, so we can
check that all lookups were successful before beginning to program the
phy.
