This patch adds the necessary device-tree settings for the ModularVision
carrier board to support the TAS2505 audio-codec.

Note: Also requires CONFIG_SND_SOC_TLV320AIC32X4_I2C to be enabled in
kernel defconfig (the tlva320aic32x4 driver also provides support for
the TAS2505 codec).

Backported from linux-6.7.0,  commit a0e026e7
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/net/phy/phy.c?id=a0e026e7b37e997f4fa3fcaa714e5484f3ce9e75

Since commit 91a7cda1 ("net: phy: Fix race condition on link status
change") all the phy_error() method invocations have been causing the
nested-mutex-lock deadlock because it's normally done in the PHY-driver
threaded IRQ handlers which since that change have been called with the
phydev->lock mutex held. Here is the calls thread:

IRQ: phy_interrupt()
     +-> mutex_lock(&phydev->lock); <--------------------+
         drv->handle_interrupt()                         | Deadlock due
         +-> ERROR: phy_error()                          + to the nested
                    +-> phy_process_error()              | mutex lock
                        +-> mutex_lock(&phydev->lock); <-+
                            phydev->state = PHY_ERROR;
                            mutex_unlock(&phydev->lock);
         mutex_unlock(&phydev->lock);

The problem can be easily reproduced just by calling phy_error() from any
PHY-device threaded interrupt handler. Fix it by dropping the phydev->lock
mutex lock from the phy_process_error() method and printing a nasty error
message to the system log if the mutex isn't held in the caller execution
context.

Note for the fix to work correctly in the PHY-subsystem itself the
phydev->lock mutex locking must be added to the phy_error_precise()
function.

This provides support for the 10-inch display variant for Modular Vision
on the i.MX8MP SMARC module.

This adds the combined devicetree for the Modular Vision 7-inch HMI.

This adds a devicetree include for specific functionality of the Modular
Vision SMARC module carrier.
The audio interface and GPIO expander are not working yet.

The display and backlight enable pins are configured in the respective
display DTs. Remove them from the imx8mp-d18 base DT.

The deletion of the B79 nodes didn't work as expected. Rewrote all
deletions to fix this.

This partly reverts commit 8fa40ae3. In the original commit, the
devicetree was split into two. With the splitting, cherry-picks from the
upstream repo doesn't work anymore. As a workaround, we revert the
seco-imx8mp-d18.dts to its original state, include it in a new
devicetree include and remove the B79 nodes there.

 imported from branch kuk_lf-5.10.y_android
 currently only ConXM baseboards with HDMI are supported

 On some modules the interrupt of the bd718x7 is not connected to anything,
 but the PMIC functionality is needed anyway. For such modules it would be
 helpfull if the probe function succeeds without an interrupt configured.

The boot strapping in U-Boot isn't integrated correctly yet. Because of
this, we have a collision between the ethphys. Since we don't use the
second phy right now, we disable it.

Re-enable sourcery

With the free open source plan, sourcery works only when called from the
repository's root directory. Re-enable it by calling it from there.

Also apply sourcery's suggestions to file generate_firmware_package.py,

There is no such property in device tree. Previously it was set by kernel
in runtime (see function "set_video_mode_from_xml" in guf_xml_to_dt.c).

Modified platform initialization to check for (a) @lcd@-node in device-tree
to identify systems with parallel LCD-interface and (b) presence of enabled
spread-spectrum settings in device-tree to change the IPU-DI PLL from

LCD-displays

The GPIOs for DISPLAY_ENABLE, TOUCH_INT and TOUCH_ENABLE have been moved
to the top-level .dts files because they may vary with the
baseboard/display-combination. Even worse: In the schematics of pConXS the
high-active TOUCH_ENABLE input is labeled as low-active WAKE.

The led_button lable is now set to the virtual gpio that simulates the
behavior of the old at42qt1011 cap. touch sensor.
The properties are selected for the dual-espresso board.
To remain compatible for devices with the old at42qt1011 sensors, a
corresponding overlay is added that can be applied during installation.

BCS 746-001576

The driver is derived from the input cap11xx.c driver:
drivers/input/keyboard/cap11xx.c
Instead of providing an input device, the driver registers a gpiochip
with a read-only line for each sensor-input.
The led handling was kept commented in source so that it can be
implemented if required.
The driver has so far only been tested with the cap1293 chip.

Additional dt properties:
disable-rf-filter: If set disables the RF noise filter
delta-sense: Allows to set sensivity for all inputs, the value should be
             in range 0x00 to 0x07 (see reg 0x1f in datasheet)
invert-gpio-output: If set inverts the gpioget output.

Disable sourcery check

Sourcery changed its license model to only be available for open source
projects with the free plan. According to the documentation, sourcery
should detect automatically whether it is running on an open source
repo. This does not work in our case, though. Disable it until we find a
way to correctly make it work.

The display uses dual LVDS, so the clock-frequency property in the panel
node must be set to a value twice as high as the typical display freq.
Overall the output visually looks good and the frequency is within the
specified range. However, the power sequence and porches have not yet
been measured.
In addition, the auo-g156han02.dtsi file contains some information on how
to achieve the desired display clock via the native LVDS interface.

BCS 746-001569

By default the VIDEO_PLL1 frequency defined in the imx8mp.dtsi is not
easily adjustable from lower devicetrees. Add a macro that makes it
possible to adjust the frequencies in the base dts files as it is
already possible for imx8mm. In this way, the video pll can be set
explicitly for a specific display.

BCS 746-001569

Add 987MHz setpoint for the AUO G156HAN02 display.

The i.MX6 ULL has an audio block equipped, that can generate audio via a
standard GPIO. Since the MQS (Medium Quality Sound) is a very basic audio
interface, it doesn't provide any filtering of unwanted artifacts in the
audio stream. This leads to a popping noise when playing audio on the
Nallino. The patch changes the SAI to always generate a signal for the
MQS and transfers the control of the external amplifier to the MQS driver.
This helps in reducing the noticeable interference when playing audio.
