ARM: kirkwood: of_serial: fix clock gating by removing clock-frequency

2013-03-14T18:26:36+00:00

commit 93fff4ce19f9978cc1c59db42760717477939249 upstream.

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.

gpio: mvebu: Add clk support to prevent lockup

2013-03-14T18:26:36+00:00

commit de88747f514a4e0cca416a8871de2302f4f77790 upstream.

The kirkwood SoC GPIO cores use the runit clock. Add code to
clk_prepare_enable() runit, otherwise there is a danger of locking up
the SoC by accessing the GPIO registers when runit clock is not
ticking.

rtc: rtc-mv: Add support for clk to avoid lockups

2013-03-14T18:26:36+00:00

commit 89c58c198b252f2bc20657fdd72a2aea788c435c upstream.

The Marvell RTC on Kirkwood makes use of the runit clock. Ensure the
driver clk_prepare_enable() this clock, otherwise there is a danger
the SoC will lockup when accessing RTC registers with the clock
disabled.

ARM: at91/DT: remove atmel,use-dma-* from 9x5 and 9n12 USART nodes

2013-02-28T13:38:38+00:00

commit c3f0f282d950a1e87496a2633ed9e924e275ff8c upstream.

Fix the use of USART on both at91sam9x5 and at91sam9n12. In DTS, the
atmel,use-dma-[rx|tx] property is present but a DMA channel cannot be used.
Indeed the connexion between the DMA engine and the slave is not implemented
yet in Device Tree.
Note however that this property is also used for PDC (private DMA) on older
SoCs. This is why the driver alone cannot determine the validity of this
property.

From Nicolas Ferre:
Here are fixes for AT91 that are mainly related to device tree.
One RM9200 setup option is the only C code change.
Some documentation changes can clarify the pinctrl use.
Then, some defconfig modifications are allowing the affected platforms
to boot.

ARM: vexpress: Enable A7 cores in V2P-CA15_A7's Device Tree

2013-01-24T12:19:23+00:00

As the kernel is able to cope with multiple clusters,
uncomment the A7 cores in the Device Tree for V2P-CA15_A7
tile, making all 5 cores available to the user.
