[PATCH 7/7] ARM: dts: add Qualcomm APQ8060-based Dragonboard

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is the first Dragonboard based on APQ8060 and PM8058. It
was produced in 2011 in cooperation between Qualcomm and
BSQUARE.

Signed-off-by: Linus Walleij <linus.walleij@xxxxxxxxxx>
---
ChangeLog v1->v2:
- Do not use phandles to define the board, keep the hierarchical
  structure of the other qcom DTS files.
- Move levelshifter under the regulators node.
- Do not pull up the GPIO for SDC3 card detect.
- Add the GSBI12 I2C channel and its pins.
- Add the AK8975 magnetometer on the GSBI12 I2C line.
- Add the BMP085 pressure sensor on the GSBI12 I2C line.
- Drop the @1 from the primary fixed regulator.
- Move the PMIC RTC reg value to 0x1e8 where is actually is.
