The initial intended user for this are the mc13xxx mfds in spi mode.

Not sure what you generated this patch against but it doesn't apply to
my topic/core or against -next. Please regenerate it against
topic/core, it looks good.

For years now, project i2c-tools has been carrying a modified copy of
linux/i2c-dev.h for use by user-space applications
accessing /dev/i2c-* device nodes. The modified copy includes parts of
linux/i2c.h as well as i2c_smbus_*() inline functions mimicking their
kernel counterparts.
Why it was
Minimize differences between kernel and user-space flavors of
linux/i2c-dev.h.

Properly split i2c-dev.h into parts:
* The i2c_smbus_* inline functions go to a dedicated user-space header
file for now (and later to a library.)
* The parts from the kernel's i2c.h go away, and applications will include
linux/i2c.h explicitly from now on.
* The parts from the kernel's

As the bus driver side implementation of I2C_M_RECV_LEN is heavily
tied to SMBus, we can't support received length over 32 bytes, but
let's at least support that.
In practice, the caller will have to setup a buffer large enough to
cover the case where received length byte has value 32, so minimum

This change converts the mc13xxx core to use regmap rather than direct

The spidev member of mc13xxx struct becomes redundant and is removed.
Extra debugging aids are added to mc13xxx_reg_rmw.
Mutex init is moved to before
This patch adds clk_prepare/clk_unprepare calls to the i2c-pxa
driver by using the helper functions clk_prepare_enable and
clk_disable_unprepare.
