Subject[PATCH v3] ARM: dts: tpc: Device tree description of the iMX6Q TPC board
Date
This commit adds device tree description of Kieback & Peter GmbH
iMX6Q TPC board.

Signed-off-by: Lukasz Majewski <lukma@denx.de>

---
Changes for v3:
- Provide proper compatible for RTC DTS node
- Remove wrong comment style for beeper
- Add proper SPDX entries for DTS files
- Add vendor prefix to a separate patch

Changes for v2:
- SPDX license identifiers used
- Separate regulators
- Proper beeper driver
- Use of the lcd panel (with compatible) instead of timings provided in
device tree
- Add IRQ types (like IRQ_TYPE_EDGE_FALLING) and GPIO active levels (like
GPIO_ACTIVE_HIGH)
- Remove not needed nodes
- Make W=1 dtbs compilation with no errors
