This is the register layout of the litesd peripheral for the fusesoc
based Microwatt SoC.
It requires a description of the system clock, which is hardcoded to
100MHz.

Each ASoC platform driver is named by rpmsg channel. ASoC machine
driver can parse "fsl,rpmsg-channel-name" property to figure out which
ASoC platform driver it should link with.

This patch can register different ASoC platform drivers if there are
several rpmsg channels. Thus sound cards based on different rpmsg
channels can link to their respective platform drivers. Besides, the
name of driver is equal to the name of rpmsg channel.

Rpmsg channel for MICFIL can also be created through rpmsg name service
announcement. If this driver is probed, Cortex-A can access MICFIL
which is actually controlled by Cortex-M through rpmsg channel for
MICFIL. This driver also helps register ASoC platform device thus use
of PLATFORM_DEVID_AUTO
Add a string property to assign the rpmsg channel this sound card sits
on. This property can be omitted if there is only one sound card and it
sits on "rpmsg-audio-channel".

At a previous time, we have successfully created a virtual sound card
based on rpmsg. The sound card works under this mechanism Cortex-A core
tells the Cortex-M core the format, rate, channel, .etc configuration
of the PCM parameters and Cortex-M controls real hardware devices such
as SAI and DMA.

Add firmware version details to the hardware description, which is
printed at boot and in case of an oops.
Use /hypervisor if we find it, though currently it only exists if we're
running under qemu.

tells us we're running unde

Hi all,
Today's linux-next merge of the powerpc tree got conflicts in:
arch/powerpc/Makefile
arch/powerpc/kernel/Makefile
between commits:
4f62512adbe9a ("kbuild: use obj-y instead extra-y for objects placed at the
head")
0f17eda6118db ("kbuild: remove head-y syntax")
from the kbuild
Clean up config files by:
- removing configs that were deleted in the past
- removing configs not in tree and without recently pending patches
- adding new configs that are replacements for old configs in the file
For some detailed information, see Link.
