I don't object to this patch.
However just FYI, it should no

To calculate the integer part of the frequency ratio, the whole output
path has to be considered (post and pre are optional):
Ndiv = (pre * target * 4 * post) / source
In the current implementation only the fixed- and pre-divider is
considered, but the post-divider is omitted.
To calc
The DT probe uses a dynamically allocated base for the spi core. This is a
completely different numbering scheme than in the non-DT probe.

Add a function to find a spi_device via DT device_node.
The patch is based on the way i2c does it.
This is intended for devices that depend on multiple subsystems and are

Hi!
This series adds devicetree support for the wm8974 connected via SPI/SSI to an
imx. The series was developed on an imx27 with a wm8974 connected via SPI.
That is why two patches for the SPI subsystem are also provided, which may be
also usefull without the wm8974 stuff. As they are needed, I i
This is the initial support for a wm8974 sound codec connected to an imx ssi.
It follows along the lines of the imx-sgtl5000 driver.
* only the playback dai link is implemented.
* DT only driver, working with the fsl_ssi driver and imx21 compatible

The wm8974 can be controlled via i2c or spi. The current driver only supports
i2c. Add SPI as possible bus.
As the driver has to distinguish the bus type, pass this info via the
wm8974_priv.
This reverts c2562a8e3b5f871ad0b73caf98bb7541e8724efc, because the driver now
needs it back.
This is base

When spi client does the spi transfer and does not sets
the bits_per_word for each transfer then set it as default
of spi device in spi core before calling low level transfer.
Removing the similar code from spi-tegra20-slink driver as
it is not required.

Currently the master->setup() is called unconditionally.
The assumption is that every driver need to implement this
callback. This encourages drivers to populate empty functions
to prevent crashing.
This patch prevents the call of master->setup() if it is not
populated.
