From: Marcin Niesluchowski
There is no possibility to clear additional kmsg buffers,
get size of them or know what size should be passed to read
file operation (too small size causes it to retrun -EINVAL).
Add following ioctls which solve those issues:
* KMSG_CMD_GET_BUF_SIZE
* KMSG_CMD_GET_READ
This patch adds selftests framework and four test scenarios for kmsg.
The framework shape and code was inspired by similar selftests framework
for kdbus.

These two functions are added to ease management of clocks obtained
from OF device nodes.
They are particulary useful while iterating over DT subnodes using e.g.
for_each_child_of_node(dev->of_node, child) in order do get resources

I guess that the approach above would require split into soc-specific and
board-specific part (as I said, dividers arrangement is s
This humble patch for linux-next is a first small step towards further attempts
to add LSM hooks for kdbus. In order to implement useful callbacks within given
LSM (SMACK, SELinux) knowledge about kdbus structures defined in these headers
must be easily accessible. Therefore these headers must be
These headers are required to implement LSM hooks for kdbus
and possibly other things that might deal with kdbus.

Hi,
First of all, I'm sorry for this no-subject covering letter. Accidents
never happen only in a perfect world.

New option CONFIG_COPY_VECTOR_TABLE_TO_SRAM_ADDR allows specification

Note that enabling tx DMA resulted in messy output, so I didn't configure
it in the .dts file - however nothing in the code prevents one from doing
so. Also note that original reference UART driver from Emcraft did not
implement tx DMA at all.

This is a very cheap and simple implementation of pinctrl driver
for Kinetis SoC - its primary role is to provide means for enabling UART
fuctionality on I/O PORT_E which will be utilized by the commits
yet to come.

Surprisingly small amount of work was required in order to extend already
existing eDMA driver with the support for Kinetis SoC architecture.

all occurences of CONFIG_ARCH_KINETIS from fsl-edma.c - now it
looks more like fsl-lpuart driver (boolean 'kinetis' field in the main
driver structure).
