rsrc-card which is using DPCM feature was created for Renesas sound.
But not only Renesas, but many SoC can use this driver, because
it is based on simple-card driver.
To use it as more open driver, rsrc-card will be renamed to
simple-scu-card. In order to easy patch review, as 2nd step,
this patch adds new compatible "simple-scu-audio-card";

rcar-card used specific property, not "simple-audio-card",
but it should be now. Actually, rsrc-card is upstreamed driver,
but noone is using it on upstream. The user is only local,
and it is only me. Thus, there is no compatible break by this patch.
This patch uses "simple-audio-card" prefix.
And it removes rcar-card specifix compatible too.

rsrc-card has board specific compatible (= lager/koelsh), but these were
created as 1st prototype, and it is used in my test environment only.
Now normal user can use generic compatible (= renesas,rsrc-card).
Removing these board specific compatible doesn't breake compatibility.
This patch remove these.

Signed-off-by: NOder Chiou <oder_chiou@realtek.com>
Signed-off-by: NMark Brown <broonie@kernel.org>

The devices from the ADAU17X1 family all have a MCLK clock input which
supplies the master clock for the device. The master clock is used as the
input clock for the PLL. Currently the MCLK rate as well as the desired PLL
output frequency need to be supplied by calling snd_soc_dai_set_pll() form
a machine driver.

Add support for specifying the MCLK using the common clock framework. In
addition to that also automatically configure the PLL to a suitable rate
if the master clock was provided using the CCW. This allows to use the
CODEC driver without any special configuration requirements from the
machine driver.

While the PLL output frequency can be configured over a (more or less)
continuous range the narrowness of the range and the other constraints of
the clocking tree usually only result in two output frequencies that will
actually be chosen. One for 44.1kHz based rates and one for 48kHz based
rates, these are the rates that the automatic PLL configuration will use.
For the rare case where a non-standard setup is required a machine driver
can disable the auto-configuration and configure a custom frequency using
the existing mechanisms.

If the common clock framework is not enabled clk_get() will return NULL and
the driver will function as before and the clock rate needs to be
configured manually.
