This patch series adds initial device trees for the Samsung Galaxy A3/A5 (2015)
and the Wileyfox Swift (a re-branded Longcheer L8150), three smartphones
based on the MSM8916 SoC. The device trees provde basic support for SDHCI,
USB device mode and regulators.
The idea is to leverage the efforts that went into mainline for
the Dragonboard 410c. So far this is going quite well:
In addition to the functionality provided by the initial device trees,
Display/GPU, touchscreen, sound and sensors also seem to work in initial tests.
Those will be added in future patch sets.
Changes in v2:
- Add initial device tree for Longcheer L8150
- Document new device tree bindings
v1: https://lore.kernel.org/linux-arm-msm/[email protected]/

2.22.0
Samsung Galaxy A3 (SM-A300FU) and Samsung Galaxy A5 (SM-A500FU)
are smartphones using the MSM8916 SoC released in 2015.
Add a device tree for A3U and A5U with initial support for:
- SDHCI (internal and external storage)
- USB Device Mode
- UART (on USB connector via the SM5502 MUIC)
- Regulators
The two devices (and all other variants of A3/A5 released in 2015)
are very similar, with some differences in display, touchscreen
and sensors. The common parts are shared in
msm8916-samsung-a2015-common.dtsi to reduce duplication.
The device tree is loosely based on apq8016-sbc.dtsi and the
downstream kernel provided by Samsung, mixed with a lot of own
research.

Changes in v2:
- Remove msm8916-samsung-a2015-common-pins.dtsi, move to main .dtsi
- Update s4/l17 regulator-max-microvolt, remove regulator-always-on
- Use muic extcon device for both VBUS/USB-ID in usb@78d9000
- Move i2c-muic out of soc { ... } node
