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: NThomas Petazzoni <thomas.petazzoni@free-electrons.com> Acked-by: NAndrew Lunn <andrew@lunn.ch> Signed-off-by: NJason Cooper <jason@lakedaemon.net>

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.

Note that the pinctrl conversion also fixes GPIO support for ns2 boards. Since commit f9e75922: "ARM: Kirkwood: Make use of mvebu pincltl and gpio", the mvbu_gpio driver is used for DT boards. As mvbu_gpio relies on the pinctrl driver, then a pinctrl definition must be given to allow the GPIO configuration.
