This series updates/adds Device Tree support for I2SE's Duckbill
device family.

The Duckbill devices are small, pen-drive sized boards based on
NXP's i.MX28 SoC. While the initial variants (Duckbill series) were
equipped with a micro SD card slot only, the latest generation
(Duckbill 2 series) have an additional internal eMMC onboard.

Both device generations consists of four "family members":

- Duckbill/Duckbill 2: generic board, intended to be used as
  baseboard for custom designs and/or as development board

- Duckbill EnOcean/Duckbill 2 EnOcean: come with an EnOcean
  daugther board equipped with the popular TCM310 module

- Duckbill 485/Duckbill 2 485: as the name implies, these
  devices are intended to be used as Ethernet - RS485 converters

- Duckbill SPI/Duckbill 2 SPI: not sold separately, but used
  in I2SE's development kits for Green PHY HomePlug Powerline
  communication

Because the Duckbill series is EOL, this patch series only adds
support for the latest Duckbill 2 series devices. However,
support for the generic Duckbill board was already mainline,
so update it to match vendor tree DT.

Changes since v1:
- dropped device tree include (shared common definitions)
- added patch 9 (DT documentation file)
- applied reviewers hints
- rebased

While at tweak some more settings for the default product:
- enable lradc
- adjust USB dr mode
- add default triggers for LEDs
- get rid of regulators simple-bus container
- adjust phy reset duration

* [PATCH v2 4/9] ARM: dts: imx28-duckbill: enable spi, i2c and uart pins
@ 2017-01-22 22:22     ` Michael Heimpold

From: Michael Heimpold @ 2017-01-22 22:22 UTC (permalink / raw)
  To: linux-arm-kernel

While at tweak some more settings for the default product:
- enable lradc
- adjust USB dr mode
- add default triggers for LEDs
- get rid of regulators simple-bus container
- adjust phy reset duration

* [PATCH v2 8/9] ARM: dts: add support for I2SE Duckbill 2 SPI
@ 2017-01-22 22:22     ` Michael Heimpold

From: Michael Heimpold @ 2017-01-22 22:22 UTC (permalink / raw)
  To: linux-arm-kernel

This machine is based on I2SE's Duckbill 2 board and is sold as part of I2SE's
PLC Bundle for IoT. This is a development kit for Homeplug Green PHY based
powerline products based on Qualcomms QCA7000 chip.

Hi,

since the subject line suggests something different as the actual
complete patch does, this needs to be changed.

@Shawn, @Fabio: Do we need a single patch for every point or is it
possible to squash some?

since the subject line suggests something different as the actual
complete patch does, this needs to be changed.

@Shawn, @Fabio: Do we need a single patch for every point or is it
possible to squash some?

Just a nit. Please place the reg property before the compatible in order

Please replace all fsl.imx28 with fsl,imx28

Maybe this patch should come before adding the Duckbill 2 board dts files.

Just curious: do you use mxs-auart to interface to a rs485
transceiver? If so, would you have mxs-auart patches that add rs485?

Just curious: do you use mxs-auart to interface to a rs485
transceiver? If so, would you have mxs-auart patches that add rs485?

Thanks

Due to the lack of hardware support in mxs-auart for rs485, we decided
to use a more expensive hardware transceiver with auto direction feature.
So the rs485 is (mostly) transparent for upper layers.

Michael
