2013-03-08ARM: kirkwood: of_serial: fix clock gating by removing clock-frequencyJason Cooper
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.

2013-02-28arm: kirkwood: mplcec4: use Device Tree to probe SDIOThomas Petazzoni
Now that the mvsdio driver has a Device Tree binding, and the SDIO controller is declared in kirkwood.dtsi, migrate the mplcec4 board to use the Device Tree to probe the SDIO controller and to mux the pins of the SDIO interface correctly. This patch has not been tested, it remains to be tested by a person having access to the hardware.
