This patch is an idea I've had
With the write_sec method, we no longer need to override the default
L2C disable method, and we no longer need the L2C set_debug method.
Both of these can be handled via the write_sec method.

Hi,
This is the seventh round of the OMAP SSI driver patches. The plan is
to get it merged into 3.16.
Changes since PATCHv2 [0]:
* Readded generic HSI client binding and Nokia N900 modem support.
They are also intended to be added in 3.16 and useful for testing
the SSI driver, so I think
Expose method for registering and unregistering HSI clients, so that
client drivers can register other client drivers.
This is useful for HSI drivers, which want to use the functionality
of other HSI drivers. For example the N900 modem driver can load HSI
drivers for mcsaab protocol and speech
Make HSI channel ids platform data, which can be provided
by platform data.
