[PATCH v3 0/4] ARM: dts: Add support for the WP8548 and mangOH Board

[PATCH v3 0/4] ARM: dts: Add support for the WP8548 and mangOH Board

[Neil Armstrong]

In order to support the Qualcomm MDM9615 in the Sierra Wireless WP8548
Modules, and on the open hardware mangOH board WP8548 DTSI, mangOH board DTS
and corresponding dt-bindings..

This patchset depends on pinctrl [merged], clk [merged], pmic [1], arm-soc [merged],
arm-soc-dt [2], patchsets.

This patchset is part of a global SoC + Module + Board support for the
Sierra Wireless mangOH Board support with the WP8548 module.

[2] http://lkml.kernel.org/r/1471951850-29842-1-git-send-email-narmstrong@baylibre.com

Changes since v2 at : http://lkml.kernel.org/r/1471525881-2797-1-git-send-email-narmstrong@baylibre.com
 - Changes vendor prefix to "swir"

Changes since v1 at : http://lkml.kernel.org/r/1466160132-24574-1-git-send-email-narmstrong@baylibre.com
 - Dropped USB nodes
 - Dropped sx150x specific attribute
