[PATCH v2 0/5] Add proper support for Compulab CM-A510/SBC-A510

[Sebastian Hesselbarth]

This is v2 of the patch set to improve current mainline support for
the Compulab CM-A510 System-on-Module (SoM) and its default Compulab
SBC-A510 base board.

Compared to v1 [1] there have been the overall changes:
- Drop i2c-mux-pinctrl rework as Wolfram Sang raised concerns with
  respect to OF_DYNAMIC. Instead we add i2c-mux-pinctrl node by
  default and wait until corresponding driver respects disabled
  sub-bus nodes. This will add 3 additional i2c busses to all
  Dove based boards, but no functional change with respect to
  i2c-0.
- Split patches dealing with arch/arm/boot/dts/Makefile to route
  them though arm-soc directly.

Other patches of v1 have already been taken by MVEBU SoC maintainers
as fixes.

Patches are based on v4.1-rc1 and are intended for v4.2. All patches
contain appropriate Acked-by's from related maintainers. Patches 3
and 5 should go thought arm-soc directly, the rest can go though
mvebu tree.

[PATCH v2 2/5] ARM: dts: dove: Add internal i2c multiplexer node

[Sebastian Hesselbarth]

This adds a i2c-mux-pinctrl node to dove.dtsi for the internal i2c
mux found on Dove SoCs. Up to now, we had no board using any of the
two additional i2c busses, so make sure the change does not break
any existing boards.

Therefore, we rename the i2c-controller node label to "i2c" and
enable it by default. Also, the dedicated sub-bus (now "i2c0") is
enabled by default. The two optional sub-busses require additional
external pin-muxing, so disable them by default.

[PATCH v2 4/5] ARM: dts: dove: Add proper support for Compulab CM-A510/SBC-A510

[Sebastian Hesselbarth]

Existing dts file for Compulab CM-A510 was very limited due to missing
hardware. Now that we actually found somebody with that board, properly
rework it to provide a CoM/SoM include and a board file for Compulab's
SBC-A510.

Both the CM-A510 SoM and the SBC-A510 can be configured with different
options, so we only enable a minimum set of options. The actual board
configuration will have to be set by either the bootloader or user.

Although functionally not required, repeat even disabled nodes again
to increse their visibility in the dtsi/dts files.

[PATCH v2 4/5] ARM: dts: dove: Add proper support for Compulab CM-A510/SBC-A510

[Sebastian Hesselbarth]

Existing dts file for Compulab CM-A510 was very limited due to missing
hardware. Now that we actually found somebody with that board, properly
rework it to provide a CoM/SoM include and a board file for Compulab's
SBC-A510.

Both the CM-A510 SoM and the SBC-A510 can be configured with different
options, so we only enable a minimum set of options. The actual board
configuration will have to be set by either the bootloader or user.

Although functionally not required, repeat even disabled nodes again
to increse their visibility in the dtsi/dts files.

Usually even the change of the arch/arm/boot/dts/Makefile go to
arm-soc through mvebu. For patch 5 it makes sens because if the series
is spited then the Makefile could be merged before the new file
to build.

So unless, Arnd or Olof really want to pick the patches 3 and 5 I will
apply the patches 2 to 5 on mvebu/dt.

Arnd, Olof, do you agree?

Thanks,

Gregory
