This patch adds upper half driver for IPCC character driver. IPCC is a Inter Processor Communication Controller. Driver is still immature and not thoroughly tested, thus CONFIG_EXPERIMENTAL is required. Signed-off-by: Michał Łyszczek <michal.lyszczek@bofc.pl>

|
|
If enabled, data read and written to/from IPCC will be
|
|
buffered in driver. This will reduce thread waiting for
|
|
read and write to complete during busy period, but it
|
|
will also increase RAM usage.
|
|
|
|
Buffer size for tx and rx can be separately defined for
|
|
each channel during driver registration.
