commit d815e0f0 ("ASoC: samsung: smdk_wm8994: don't select unnecessary
Platform")

Current ALSA SoC avoid to add duplicate component to rtd,
and this driver was selecting CPU component as Platform component.
Thus, above patch removed Platform settings from this driver,
because it assumed these are same component.

But, some CPU driver is using generic DMAEngine, in such case, both
CPU component and Platform component will have same of_node/name.
In other words, there are some components which are different but
have same of_node/name.

In such case, Card driver definitely need to select Platform even
though it is same as CPU.
It is depends on CPU driver, but is difficult to know it from Card driver.
This patch reverts above patch.

Since there are multiple IPCs being sent in a short span of time, there
is a possibility of more than one message being on the Rx list after
receiving response from firmware. In such cases, when the first
notification of interrupt from firmware is received, driver retrieves
the message from the Rx list but does not delete it from the list till
the next lock. In the meantime, when another interrupt is received from
the firmware, driver is reading the previous message again since the
previous message has not been removed from the list.

Host clears DONE bit to signal IPC target it has completed the
operation. Once this is done, IPC target i.e. DSP may proceed with the
next reply, filling registers with new portion of data.

Because of this, host should always read all registers prior to clearing
DONE and BUSY bits to ensure no desynchronization happens the time in
between clearing bits and reading message data (here, extension).
