2014-05-05ARM: dts: kirkwood: set default pinctrl for I2C1 on 6282Sebastian Hesselbarth1-2/+0
Currently, the only 6282-based Kirkwood boards that use I2C1 are Openblocks A6/A7. Both use the same default I2C1 pinctrl setting from kirkwood-6282.dtsi. Move the pinctrl setting to the I2C1 node directly and put a note in front of the corresponding pinctrl node to overwrite the setting on board level.

2014-05-05ARM: dts: kirkwood: set default pinctrl for NANDSebastian Hesselbarth1-2/+0
There is only one valid pinctrl setting for NAND on Kirkwood. Now that we have the setting in the common SoC pinctrl, move it to the NAND controller node directly and remove it from the individual boards. While at it, also fix up status = "okay" to "ok" on one board's NAND node.

2014-05-05ARM: dts: kirkwood: set default pinctrl for UART0/1Sebastian Hesselbarth1-6/+2
Most boards use the default UART0/1 pinctrl setting without RTS/CTS. Add the pinctrl setting to the toplevel SoC UART nodes and put a note in front of the corresponding pinctrl node to overwrite the setting on board level. Currently, both boards using a different UART pinctrl setting (Openblocks A6, A7) already overwrite the pinctrl node. While at it, also fix up some status = "ok" to "okay" and again whitespace issues on mplcec4 uart nodes.

ePAPR allows to reference the device used for console output by stdout-path property.

The device_type property is deprecated for the flattened device tree and the value "ethernet-phy" has never been defined as having a useful meaning. Neither the kernel nor u-boot depend on it. It should never have appeared in PHY bindings. This patch removes all references to "ethernet-phy" as a device_type value from the documentation and the .dts files. This patch was generated mechanically with the following command and then verified by looking at the diff. sed -i '/"ethernet-phy"/d' `git grep -l '"ethernet-phy"'` Signed-off-by: Grant Likely <grant.likely@linaro.org> Acked-by: Srinivas Kandagatla <srinivas.kandagatla@st.com> Cc: Rob Herring <rob.herring@calxeda.com> Cc: Pawel Moll <pawel.moll@arm.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Ian Campbell <ijc+devicetree@hellion.org.uk> Cc: Kumar Gala <galak@codeaurora.org> Cc: Florian Fainelli <f.fainelli@gmail.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Again, a bit of domain overlap with SoC and DT branches, but most of this is around legacy code and board support.

Gotta go somewhere.

2013-05-27arm: kirkwood: openblocks_a6: move pinmux configs to the right devicesThomas Petazzoni1-10/+16
When the pinmux mechanism was added in Kirkwood, the device driver core was not yet providing the possibility of attaching pinmux configurations to all devices, drivers had to do it explicitly, and not all drivers were doing this. Now that the driver core does that in a generic way, it makes sense to attach the pinmux configuration to their corresponding devices. This allows the pinctrl subsystem to show in debugfs to which device is related which pins, for example: pin 41 (PIN41): gpio-leds.1 mvebu-gpio:41 function gpio group mpp41 pin 42 (PIN42): gpio-leds.1 mvebu-gpio:42 function gpio group mpp42 pin 43 (PIN43): gpio-leds.1 mvebu-gpio:43 function gpio group mpp43 Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Acked-by: Andrew Lunn <andrew@lunn.ch> Tested-by: Atsushi Yamagata <yamagata@plathome.co.jp> Signed-off-by: Jason Cooper <jason@lakedaemon.net>
2013-03-09ARM: kirkwood: of_serial: fix clock gating by removing clock-frequencyJason Cooper1-2/+0
When DT support for kirkwood was first introduced, there was no clock infrastructure. As a result, we had to manually pass the clock-frequency to the driver from the device node. Unfortunately, on kirkwood, with minimal config or all module configs, clock-frequency breaks booting because of_serial doesn't consume the gate_clk when clock-frequency is defined. The end result on kirkwood is that runit gets gated, and then the boot fails when the kernel tries to write to the serial port. Fix the issue by removing the clock-frequency parameter from all kirkwood dts files. Booted on dreamplug without earlyprintk and successfully logged in via ttyS0.
