[PATCHv2] ARM: mvebu: Add Netgear ReadyNAS 2120 board

Arnaud Ebalard
2013-11-12T19:46:48Z

All hardware parts of the (mv78230 Armada XP based) NETGEAR ReadyNAS
2120 are supported by mainline kernel (USB 3.0 and eSATA rear ports,
USB 2.0 front port, Gigabit controller and PHYs for the two rear ports,
serial port, LEDs, Buttons, 88SE9170 SATA controllers, three G762 fan
controllers, G751 temperature sensor) except for:

- the Intersil ISL12057 I2C RTC Chip,
- the Armada NAND controller.

Support for both of those is currently work in progress and does not
prevent boot.

Hi,

Initial message:

This one is intended for v3.14. This depends on the recent fix I pushed
for mv78230 PCIe and also on a small patch Guenter Roeck just accepted
to have lm75 driver support GMT G751 Temperature sensor (see
https://lkml.org/lkml/2013/11/9/273).

Regarding the SATA presence and power pin definitions under pinctrl
node if you wonder, I thought it would not harm to have them for
reference even though they are currently not used. FWIW, I am currently
looking if a GPIO regulator can make any use of those.

Note changed since v2 (i.e. kept for later cleanup session):
- move clocks = <&coreclk 0> in serial node to armada-370-xp.dtsi
- add a label to most SoC nodes to avoid replaying the whole node hierarchy
- see if g762 dt binding can be fixed (no remarks done during review)

Changes since v2:

After Sebastian's comments:
- fixed order of includes (global before local)
- fixed *all* node names to use '-' instead of '_'
- Added Sebastian's Acked-by

Changes since v1:

After Andrew's comment:
- Added comment about G751 function

After Sebastian's comments:
- Changed clock frequency for a clock provider for serial line
- Added compatible string for PHY (marvell,mv88e1318s)
- Removed useless properties in clocks and gpio_keys nodes
- Made G762 clock node name unique by including g762 in it
- Changed values for macros for GPIO voltage level
- Removed comments after GPIOs
- Changed buttons and button pins names

After Jason's comment:
- Changed values for macros for input keys, removed comments

After more documenation reading:
- changed i2c compatible string to marvell,mv78230-i2c

Comments welcome,

Cheers,

a+
