[ Upstream commit e8537cad824065b0425fb0429e762e14a08067c2 ]
Perform fix similar to the one in the commit 85e444a681 ("drm/bridge:
Fix assignment of the of_node of the parent to aux bridge").
The assignment of the of_node to the aux HPD bridge needs to mark the
of_node as reused, otherwise driver core will attempt to bind resources
like pinctrl, which is going to fail as corresponding pins are already
marked as used by the parent device.
Fix that by using the device_set_of_node_from_dev() helper instead of
assigning it directly.

commit 47c03e6660e96cbba0239125b1d4a9db3c724b1d upstream.
Once the DSI Link and DSI Phy are initialized, the code needs to wait
for Clk and Data Lanes to be ready, before continuing configuration.
This is in accordance with the DSI Start-up procedure, found in the
Technical Reference Manual of Texas Instrument's J721E SoC[0] which
houses this DSI TX controller.
If the previous bridge (or crtc/encoder) are configured pre-maturely,
the input signal FIFO gets corrupt. This introduces a color-shift on the
display.
Allow the driver to wait for the clk and data lanes to get ready during
DSI enable.

commit fd2611c13f69cbbc6b81d9fc7502abf4f7031d21 upstream.
The driver code doesn't have a Phy de-initialization path as yet, and so
it does not clear the phy_initialized flag while suspending. This is a
problem because after resume the driver looks at this flag to determine
if a Phy re-initialization is required or not. It is in fact required
because the hardware is resuming from a suspend, but the driver does not
carry out any re-initialization causing the D-Phy to not work at all.
Call the counterparts of phy_init() and phy_power_on(), that are
phy_exit() and phy_power_off(), from _bridge_post_disable(), and clear
the flags so that the Phy can be initialized again when required.

commit 132bdcec399be6ae947582249a134b38cf56731c upstream.
The crtc_* mode parameters do not get generated (duplicated in this
case) from the regular parameters before the mode validation phase
begins.
The rest of the code conditionally uses the crtc_* parameters only
during the bridge enable phase, but sticks to the regular parameters
for mode validation. In this singular instance, however, the driver
tries to use the crtc_clock parameter even during the mode validation,
causing the validation to fail.
Allow the D-Phy config checks to use mode->clock instead of
mode->crtc_clock during mode_valid checks, like everywhere else in the
driver.

[ Upstream commit 55e8ff842051b1150461d7595d8f1d033c69d66b ]
By default, HPD was disabled on SN65DSI86 bridge. When the driver was
added (commit "a095f15c00e27"), the HPD_DISABLE bit was set in pre-enable
call which was moved to other function calls subsequently.
Later on, commit "c312b0df3b13" added detect utility for DP mode. But with
HPD_DISABLE bit set, all the HPD events are disabled[0] and the debounced
state always return 1 (always connected state).
Set HPD_DISABLE bit conditionally based on display sink's connector type.
Since the HPD_STATE is reflected correctly only after waiting for debounce
time (~100-400ms) and adding this delay in detect() is not feasible
owing to the performace impact (glitches and frame drop), remove runtime
calls in detect() and add hpd_enable()/disable() bridge hooks with runtime
calls, to detect hpd properly without any delay.

AUDIO_UPDATE bit (Bit 5 of MAIN register 0x4A) needs to be set to 1
while updating Audio InfoFrame information and then set to 0 when done.
Otherwise partially updated Audio InfoFrames could be sent out. Two
cases where this rule were not followed are fixed:
- In adv7511_hdmi_hw_params() make sure AUDIO_UPDATE bit is updated
before/after setting ADV7511_REG_AUDIO_INFOFRAME.
- In audio_startup() use the correct register for clearing
AUDIO_UPDATE bit.
The problem with corrupted audio infoframes were discovered by letting
a HDMI logic analyser check the output of ADV7535.
Note that this patchs replaces writing REG_GC(1) with
REG_INFOFRAME_UPDATE. Bit 5 of REG_GC(1) is positioned within field
GC_PP[3:0] and that field doesn't control audio infoframe and is read-
only. My conclusion therefore was that the author if this code meant to
clear bit 5 of REG_INFOFRAME_UPDATE from the very beginning.

commit c5f3f21728b069412e8072b8b1d0a3d9d3ab0265 upstream.
The IT6505 bridge chip has a active low reset line. Since it is a
"reset" and not an "enable" line, the GPIO should be asserted to
put it in reset and deasserted to bring it out of reset during
the power on sequence.
The polarity was inverted when the driver was first introduced, likely
because the device family that was targeted had an inverting level
shifter on the reset line.
The MT8186 Corsola devices already have the IT6505 in their device tree,
but the whole display pipeline is actually disabled and won't be enabled
until some remaining issues are sorted out. The other known user is
the MT8183 Kukui / Jacuzzi family; their device trees currently do not
have the IT6505 included.
Fix the polarity in the driver while there are no actual users.

[ Upstream commit 2d343723c7e1f9f6d64f721f07cfdfc2993758d1 ]
When a display controller driver uses DRM_BRIDGE_ATTACH_NO_CONNECTOR,
tc358767 will behave properly and skip the creation of the connector.
However, tc_get_display_props(), which is used to find out about the DP
monitor and link, is only called from two places: .atomic_enable() and
tc_connector_get_modes(). The latter is only used when tc358767 creates
its own connector, i.e. when DRM_BRIDGE_ATTACH_NO_CONNECTOR is _not_
set.
Thus, the driver never finds out the link properties before get_edid()
is called. With num_lanes of 0 and link_rate of 0 there are not many
valid modes...
Fix this by adding tc_get_display_props() call at the beginning of
get_edid(), so that we have up to date information before looking at the
modes.

Pull sound updates from Takashi Iwai:
"A fairly big update at this time, both in core and driver sides.
The core received rewrites in PCM buffer allocation handling and
locking optimizations, PCM rate updates followed by lots of cleanups.
In ASoC side, the legacy Intel drivers have been deprecated by AVS
drivers which leaded to the significant amount of code reduction.
SoundWire driver updates and other cleanups contributed more code
reduction, too.
USB-audio driver received a large cleanup of its big quirk table, and
the old snd_print*() API usages in many legacy drivers are replaced
with the standard print API.
Here are some highlights:
Core:
- More optimized locking in ALSA control code
- Rewrites of memalloc helpers for better DMA API usage
- Drop of obsoleted vmalloc PCM buffer helper API
- Continued MIDI2 UMP updates
- Support of a new user-space driven timer instance
- Update for more PCM support rates and cleanups
- Xrun counter report in the proc files
ASoC:
- Continued simplification and cleanup works for ASoC
- Extensive cleanups and refactoring of the Soundwire drivers
- Removal of Intel machine support obsoleted by the AVS driver
- Lots of DT schema conversions
- Machine support for many AMD and Intel x86 platforms
- Support for AMD ACP 7.1, Mediatek MT6367 and MT8365, Realtek
RTL1320 SoundWire and rev C, and Texas Instruments TAS2563
USB-audio:
- Add support of multiple control interfaces
- A large rewrite of quirk table with macros
- Support for RME Digiface USB
HD-audio:
- Cleanup of quirk code for Samsung Galaxy laptops
- Clean up of detection of Cirrus codecs
- C-Media CM9825 HD-audio codec support
Others:
- Rewrites to standard print API in a lot of legacy drivers"

The dw-hdmi drm bridge driver is the only one who still uses the ALSA
vmalloc helper API functions. A previous attempt to change the way of
buffer management wasn't taken for this legacy stuff, as we had little
chance for test and some risk of major breaking.
Instead, this patch moves the vmalloc buffer stuff into the dw-hdmi
driver code itself, so that we can drop them from ALSA core code
afterwards.
There should be no functional changes.

There's no need to get the length of an DT array property before
parsing the array. of_property_read_variable_u8_array() takes a minimum
and maximum length and returns the actual length (or error code).
This is part of a larger effort to remove callers of of_get_property()
and similar functions. of_get_property() leaks the DT property data
pointer which is a problem for dynamically allocated nodes which may
be freed.

If the bridge is attached with the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag set,
this driver won't initialize a connector and hence display mode won't be
validated in drm_connector_helper_funcs::mode_valid(). So, move the mode
validation from drm_connector_helper_funcs::mode_valid() to
drm_bridge_funcs::mode_valid(), because the mode validation is always done
for the bridge.

Make the default DP port preemphasis configurable via new DT property
"toshiba,pre-emphasis". This is useful in case the DP link properties
are known and starting link training from preemphasis setting of 0 dB
is not useful. The preemphasis can be set separately for both DP lanes
in range 0=0dB, 1=3.5dB, 2=6dB .
