[PATCH 0/6] ARM: OMAP2+: dts: cm-t335: initial support

[PATCH 0/6] ARM: OMAP2+: dts: cm-t335: initial support

[Uri Mashiach]

Add basic support for CompuLab cm-t335 module based on AM335X SoC.

CM-T335 is a tiny computer-on-module (CoM) / system-on-module (SoM)
The module is built around the Texas Instruments Sitara AM3352/4
system-on-chip.

The CPU is supplemented with up-to 512MB DDR3 and up-to 1GB of on-board
NAND storage, WiFi connected to SPI, Bluetooth, Analog audio, Gigabit
Ethernet, CAN bus.

From: Ilya Ledvich <ilya@compulab.co.il>

Add pinmux configurations for RGMII1 based CPSW Ethernet pins and
MDIO pins:
 - default configuration required for module in active state,
 - sleep configuration required for module in inactive state.
Add mac node with single slave device. Add nodes for davinci_mdio and
cpsw_emac0.

[PATCH 0/6] ARM: OMAP2+: dts: cm-t335: initial support

[Tony Lindgren]

Hi,

* Uri Mashiach <uri.mashiach@compulab.co.il> [151111 09:32]:
> Gentle ping

Well the merge window is ongoing, and I'm not touching anything
except fixes until they are all out of the way. And after that
I'll start applying patches for v4.5 merge window, usually by
-rc2 except when things go wrong and we have regressions with
the mainline kernel like we did during v4.3-rc cycle.

So for fixes, it's always a good time to send them. The sooner
we have fixes out of the way after each merge window, the sooner
I'll start applying new features.

So for new features, between -rc1 and -rc4. We really want to
have all the new code sit in Linux next for a few weeks before
each merge window so in general I try to have things ready togo
by -rc5 for most part and by -rc6 latest.

Regards,

Tony

[PATCH v2 0/6] ARM: OMAP2+: dts: cm-t335: initial support

[Uri Mashiach]

Add basic support for CompuLab cm-t335 module based on AM335X SoC.

CM-T335 is a tiny computer-on-module (CoM) / system-on-module (SoM)
The module is built around the Texas Instruments Sitara AM3352/4
system-on-chip.

The CPU is supplemented with up-to 512MB DDR3 and up-to 1GB of on-board
NAND storage, WiFi connected to SPI, Bluetooth, Analog audio, Gigabit
Ethernet, CAN bus.

This macro is exactly the kind we should not be doing in DT files which 
are ones that expand to multiple cells. But not really much point in 
doing 1 board differently from the rest, so:

[PATCH v2 1/6] ARM: OMAP2+: dts: cm-t335: add initial support

FYI, the extra line break at the end of the file causes whitespace
warnings when applying. And fixing that causes extra hassles with
applying the other patches in the series as the patches won't apply..
So for the next time, you may want to check that ;)

Also, the subject line should be "ARM: dts: ..." for the dts changes
so the git log loooks unified for all the ARM SoCs.

Anyways, I've fixed up those locally and applying into omap-for-v4.5/dt.

Regards,

Tony

[PATCH 5/5] ARM: dts: cm-t335: add support for bluetooth

[Uri Mashiach]

bluetooth HW is WLS1271 chip connected to UART1.

Device tree modifications:
- Pinmux for UART1.
- Pinmux for bluetooth enable GPIO.

Bluetooth enable GPIO is set to enable during startup by setting the
relevant pinmux pin to pull-up.
