arm64: dts: mediatek: mt8192-asurada-spherion: Mark trackpads as fail-needs-probe
Different Spherion variants use different trackpads on the same I2C2
bus. Instead of enabling all of them by default, mark them as
"fail-needs-probe" and let the implementation determine which one is
actually present.

Additionally, move the trackpad pinctrl entry back to the individual
trackpad nodes.

arm64: dts: mediatek: mt8192-asurada: Reserve memory for audio frontend
Some MediaTek platforms already reserve a small block of memory for the
audio frontend. These platforms reserve it at a fixed address, though it
is unclear if that is due to hardware access restrictions or simply
compacting the reserved memory blocks together.

Reserve the same size of memory on the MT8192 Asurada family as well, to
align with the other MediaTek-based ChromeOS platforms.

arm64: dts: mediatek: mt8192-asurada: Drop regulator-compatible property
The "regulator-compatible" property has been deprecated since 2012 in
commit 13511def87 ("regulator: deprecate regulator-compatible DT
property"), which is so old it's not even mentioned in the converted
regulator bindings YAML file. It should not have been used for new
submissions such as the MT6315.

Drop the "regulator-compatible" property from the board dts. The
property values are the same as the node name, so everything should
continue to work.

arm64: dts: mt8192-asurada-spherion: Add Synaptics trackpad support
Some spherion variants use Synaptics trackpad at address 0x2c in the
I2C2 bus with the generic HID-over-i2c driver, and this cannot be
distinguished from the firmware compatible string.

Support both trackpads in the same devicetree by moving the trackpad
pinctrl property to i2c2 and adding the node for Synaptics trackpad.

arm64: dts: mediatek: mt8192-asurada: Add off-on-delay-us for pp3300_mipibrdg
Set off-on-delay-us to 500000 us for pp3300_mipibrdg to make sure it
complies with the panel's unprepare delay (the time to power down
completely) of the power sequence. Explicit configuration on the
regulator node is required because mt8192-asurada uses the same power
supply for the panel and the anx7625 DP bridge.

For example, the power sequence could be violated in this sequence:
1. Bridge on: panel goes off, but regulator doesn't turn off (refcount=1).
2. Bridge off: regulator turns off (refcount=0).
3. Bridge resume -> regulator turns on but the bridge driver doesn't
   check the delay.

Or in this sequence:
1. Bridge on: panel goes off. The regulator doesn't turn off (refcount=1),
   but the .unprepared_time in panel_edp is still updated.
2. Bridge off, regulator goes off (refcount=0).
3. Panel on, but the panel driver uses the wrong .unprepared_time to check
   the unprepare delay.

arm64: dts: mediatek: mt8192: Enable cros-ec-spi as wake source
The cros_ec driver currently assumes that cros-ec-spi compatible device
nodes are a wakeup-source even though the wakeup-source property is not
defined.

Some Chromebooks use a separate wake pin, while others overload the
interrupt for wake and IO. With the current assumption, spurious wakes
can occur on systems that use a separate wake pin. It is planned to
update the driver to no longer assume that the EC interrupt pin should
be enabled for wake.

Add the wakeup-source property to all cros-ec-spi compatible device
nodes to signify to the driver that they should still be a valid wakeup
source.

arm64: dts: mediatek: mt8192-asurada: Remove CrosEC base detection node
The commit adding the ChromeOS EC to the Asurada Devicetree mistakenly
added a base detection node. While tablet mode detection is supported by
CrosEC and used by Hayato, it is done through the cros-ec-keyb driver.
The base detection node, which is handled by the hid-google-hammer
driver, also provides tablet mode detection but by checking base
attachment status on the CrosEC, which is not supported for Asurada.

Hence, remove the unused CrosEC base detection node for Asurada.

Since commit 26c9d152eb ("dt-bindings: tpm: Consolidate TCG TIS

devicetrees:

The compatible property needs to contain the chip's name in addition to
the generic "tcg,tpm_tis-spi" and the nodename needs to be "tpm@0"
rather than "cr50@0":

  tpm@1: compatible: ['tcg,tpm_tis-spi'] is too short
        from schema $id: http://devicetree.org/schemas/tpm/tcg,tpm_tis-spi.yaml#

  cr50@0: $nodename:0: 'cr50@0' does not match '^tpm(@[0-9a-f]+)?$'
        from schema $id: http://devicetree.org/schemas/tpm/google,cr50.yaml#

Fix these schema violations.

The MT8192 SoC specifies a maximum voltage for the GPU's digital supply
of 0.88V and the GPU OPPs are declaring a maximum voltage of 0.80V.

In order to keep the GPU voltage in the safe range, change the maximum
voltage for mt6315@7's vbuck1 to 0.80V as sending, for any mistake,
1.193V would be catastrophic.

ad5cc915c3 arm64: dts: mediatek: asurada: Enable audio support
Enable audio support for the Asurada platform. This consists of the
machine sound card, the rt1015p codec for the speakers, the rt5682 codec
for the headset, and the dmic codec for the internal microphone.

Newer revisions of spherion and hayato use the rt5682s codec for the
headset instead, so the codecs and card compatible are added through
separate dtsi files to prepare for that.

HDMI audio support is left out for now since the DisplayPort chip
required isn't enabled yet.
