[PATCH v2 0/4] Describe more hardware of the HTC One (M8)

[Alexandre Messier via B4 Relay]

Add hardware description for these parts of the HTC One (M8):

 - Notification LEDs
 - Bluetooth
 - NFC
 - Touchscreen

Changes in v2:
- Rebased on top of 7.0-rc6
- In patch 1, change color of one LED from amber to orange.
- In patch 1, use a multicolor LED to represent the logical grouping
  of the LEDs.
- In patches 2 and 4, note in the commit message the usage of same
  I2C bus frequency as the downstream kernel.
- In patch 3, gather Reviewed-by tag from Konrad Dybcio.
- Link to v1: https://lore.kernel.org/r/20251007-m8-dts-additions-v1-0-53d7ab3594e7@me.ssier.org

[PATCH v2 1/4] ARM: dts: qcom: msm8974pro-htc-m8: add status LEDs

[Alexandre Messier via B4 Relay]

From: Alexandre Messier <alex@me.ssier.org>

Add support for the notification LEDs on the HTC One M8.

Two LEDs are available, one orange and one green. Together,
they both form a single notification source, so use a
multicolor LED node to describe this arrangement.

[PATCH v2 2/4] ARM: dts: qcom: msm8974pro-htc-m8: add NFC support

[Alexandre Messier via B4 Relay]

From: Alexandre Messier <alex@me.ssier.org>

Add the NFC chip used in the HTC One M8 to its device tree.

The downstream vendor kernel used an I2C frequency of 384 kHz
for this bus. Use the same value as the vendor.
