2014-11-19	mfd: dln2: Add a limit check for invalid echo	Octavian Purdila
	The echo field in dln2_transfer_complete comes directly from an USB transfer and we should not trust it is valid. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Octavian Purdila <octavian.purdila@intel.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2014-11-19	mfd: dln2: Fix _dln2_transfer return code	Octavian Purdila
	If wait_for_completion_interruptible_timeout returns a positive value it may be propagated as the return value of _dln2_transfer. This contradicts the documentation of the function and exposes unnecessary internals to the callers. This patch makes sure to set the return value to 0 in that case.

2014-11-10	mfd: Add support for Diolan DLN-2 devices	Octavian Purdila
	This patch implements the USB part of the Diolan USB-I2C/SPI/GPIO Master Adapter DLN-2. Details about the device can be found here: https://www.diolan.com/i2c/i2c_interface.html. Information about the USB protocol can be found in the Programmer's Reference Manual [1], see section 1.7. Because the hardware has a single transmit endpoint and a single receive endpoint the communication between the various DLN2 drivers and the hardware will be muxed/demuxed by this driver. Each DLN2 module will be identified by the handle field within the DLN2 message header. If a DLN2 module issues multiple commands in parallel they will be identified by the echo counter field in the message header. The DLN2 modules can use the dln2_transfer() function to issue a command and wait for its response. They can also register a callback that is going to be called when a specific event id is generated by the device (e.g. GPIO interrupts). The device uses handle 0 for sending events.
