[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

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.
