This patch adds the possibility to have a spi device without a cs.
For example, the dts file should look something like this:
spi-controller {
gpios = <&pio1 1 0 /* cs0 */
0 /* cs1, no GPIO */
&pio2 2 0>;/* cs2 */

For some reason we've had an explicit KERN_INFO for GPR dumps. With
recent changes we get output like:
<6>GPR00: ef855eb0 ef858000 0001 00d0 f100 ffbc8000
The KERN_INFO is causing the <6>. Don't see any reason to keep it
around.

The old PowerSurge SMP (ie, dual or quad 604 machines) code has

One is cpu_possible_map is set too late (the device-tree is bogus)

Hi,
I'm writing a linux driver that uses an external interrupt (ppc 405ex). I'm
using GPIO pin 30 (external IRQ 1) connected to UIC1. I'm aware of the
virtual interrupt stuff, so I added a new node to my device tree in order to
get proper virtual IRQ number. This node describes an external event an

When a process tries to read/write a disconnected i2c device, it receives a

When using the Freescale DMA controller in external control mode, both the
request count and external pause bits need to be setup correctly. This was
being done with the same function.
The 83xx controller lacks the external pause feature, but has a similar
feature called external start. This featu
Use the DMA_SLAVE capability of the DMAEngine API to copy/from a
scatterlist into an arbitrary list of hardware address/length pairs.
This allows a single DMA transaction to copy data from several different
devices into a scatterlist at the same time.
This also adds support to enable some control
You will have to program GPIO's to select appropriate external IRQ as
