[PATCH v4 0/8] Add support for sam9x60 curiosity board

[Durai Manickam KR]

This series of patches is meant to address the following:
- Moving of flexcom definitions from board file to SoC file and
   some minor changes to its properties.
- Add support for the new sam9x60 curiosity board based on the
   existing sam9x60 SoC.

Changes in v4:
--------------
- Added the missed property atmel,usart-mode in uart5
- Renamed the led label.

Changes in v3:
--------------
- Updated commit logs mentioning each author's contribution.
- Author name is updated based on the linux mainline guidelines.
- updated the description file such that sam9x60 curiosity is
  added together with sam9x60ek as an enum.
- Updated the entries in the regulator container alphabetically
  sorted.
- Added label name and node name following the guidelines.

Changes in v2:
--------------
- Added generic names for regulator node.
- Removed the #addredd-cells and #size-cells property which shows
  compilation warning.
- Removed the property "status=okay" as this is default.
- No underscores used for the pinctrl definitions and node names.
- Organised the patches in the logical way.
- Bindings are made separate patch.

[PATCH v4 1/8] ARM: dts: at91: sam9x60: Fix the label numbering for the flexcom functions

[Durai Manickam KR]

From: Manikandan Muralidharan <manikandan.m@microchip.com>

Fixed the label numbering of the flexcom functions so that all
13 flexcom functions of sam9x60 are in the following order when the missing
flexcom functions are added:

flx0: uart0, spi0, i2c0
flx1: uart1, spi1, i2c1
flx2: uart2, spi2, i2c2
flx3: uart3, spi3, i2c3
flx4: uart4, spi4, i2c4
flx5: uart5, spi5, i2c5
flx6: uart6, i2c6
flx7: uart7, i2c7
flx8: uart8, i2c8
flx9: uart9, i2c9
flx10: uart10, i2c10
flx11: uart11, i2c11
flx12: uart12, i2c12

The From: field is from you and the 1st SoB is Manikandan. From and 1st SoB
should match. Can you check and resubmit. See this for more details:

The compatible list here is different from the one you inserted in dtsi. Is
there a reason? Is there a reason for this? If so, could you please specify
it in commit description.

[PATCH v4 5/8] ARM: dts: at91: sam9x60: Add DMA bindings for the flexcom nodes

[Durai Manickam KR]

From: Manikandan Muralidharan <manikandan.m@microchip.com>

Add dma bindings for flexcom nodes in the soc dtsi file. Users those who
don't wish to use the DMA function for their flexcom functions can
overwrite the dma bindings in the board device tree file.

Please keep 1 space b/w AT91_PIOA and the number, e.g. "AT91_PIOA 2" as
some may search in the file for the presence of this pin on other IPs. I
haven't checked other pinctrl definitions for the rest of IPs, can you
please handle them?

Is this disabled with a reason? I see there is no conflict with other
enabled IPs on this board.
