Subject: spi_write_then_read with different tx/rx bits_per_word
Date: Wed, 8 Jan 2014 23:35:38 +0100	[thread overview]
Message-ID: <20140108223538.GA2861@frolo.macqel> (raw)

Hello linux spi architects,

I am currently writing a driver for a peripheral that uses spi
for its configuration.  The spi interface of that device
presents a set of read-only or read-write registers with 7-bit
addresses, but 8- or 16-bit values.

Is there a convenience function similar to spi_write_then_read
to handle that case or must I roll my own one in my driver ?

Thanks in advance

Philippe De Muyter
