Subject: [PATCH v4] ARM: DT: apq8064: Add i2c device nodes
This patch adds i2c pinctrl DT node for IFC6410 board.
It also adds necessary DT support for i2c eeprom which is present on
IFC6410.
Tested on IFC6410 board.
Signed-off-by: Kiran Padwal <kiran.padwal@...rtplayin.com>
---
Changes since v3:
- Removed pinctrl DT node.
Changes since v2:
- Renamed pinmux i2c subnode "i2c1_pinmux" to "i2c1".
- Removed labes of node.
- Used canonical value as "okay" instead of "ok".
- Used macros.
Changes since v1:
- Renamed pinmux phandle "qcom_pinmux" to "tlmm_pinmux".
- Updated pinmux interrupt.
