[PATCH V2 0/8] ARM: dts: imx6ull: Add chargebyte Tarragon support

[PATCH V2 0/8] ARM: dts: imx6ull: Add chargebyte Tarragon support

[Stefan Wahren]

This series adds the support for chargebyte Tarragon, which is an Electrical
Vehicle Supply Equipment (EVSE) for AC charging stations
(according to IEC 61851, ISO 15118).

The Tarragon board is based on an i.MX6ULL SoC and is available in
4 variants (Master, Slave, SlaveXT, Micro), which provide more or
less peripherals.

Supported features:
  * 512 MB DDR RAM
  * eMMC
  * Debug UART
  * 100 Mbit Ethernet
  * USB 2.0 Host interface
  * Powerline communication (QCA700x)
  * 2x RS485
  * Digital in- and outputs (12 V)
  * One-Wire master for external temp sensors
  * 2x relay outputs
  * 2x motor interfaces
  
The Tarragon hardware is bundled with a charging stack under the name Charge Control C: 
https://chargebyte.com/products/charging-station-communication/charge-control-c

This series is rebased on top of:
https://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux.git?h=for-next

Changes in V2:
- after fixing technical problems send patches directly from chargebyte address
  and drop the related signed-off-by
- add Krzysztof's Acked-by
- improve commit messages (patch 3, 4, 5)
- make iis328dq fallback to lis331dl as suggested by Jonathan
- fix order of Tarragon entries in FSL schema
- improve Tarragon led node names and drop label as suggested by Krzysztof
- change Tarragon SVNS pinctrl settings after internal discussion
  with chargebyte hardware team
- drop broken-cd in Tarragon common DTSI which is not necessary for eMMC
- add no-sd and no-sdio for eMMC interface of Tarragon

[PATCH V2 4/8] dt-bindings: iio: st-sensors: Add IIS328DQ accelerometer

[Stefan Wahren]

The ST IIS328DQ is an accelerometer sensor, which is compatible with
the already supported ST H3LIS331DL. So add the new compatible
with a fallback to the ST sensor binding.

[PATCH V2 8/8] ARM: imx_v6_v7_defconfig: Enable Tarragon peripheral drivers

[Stefan Wahren]

We need to enable some drivers in order to use the following peripherals
of Tarragon:
  * QCA7000/7005 Powerline chip
  * One-Wire Master DS2484 with external thermal sensors
  * external 4 pin PWM fan
  * ST IIS328DQ I2C accelerometer

i'm a little bit confused about consider this as "fixes", but i'm fine 
with them going your tree.

need to resend patch 4 and 5 in V3?
