Add basic 'lspci' command to list PCI devices. This command can be
enabled with the new Kconfig PCI_SHELL.
Example:
uart:~$ lspci
0:1 8086:7010 class: 0x1, 1, 4, I/O, addrs: 0xC000-0xC00F, IRQ -1

If data is received before an IRQ handler was set and enabled,
hardware sets the ORE flag. Once set, the IRQ routine starts
hogging the CPU until ORE is cleared. This change will clear
the flag when user code attempts to drain incoming data.

Added bidirectional I2S support for Intel S1000
- Added implementation for I2S receive mode
- Extended driver instances to support 3 I2S ports
- Added DMA channel mappings for upto 4 I2S ports
- Utilized k_msgq to track buffers through the driver
- Allocate buffers for audio reception in the driver
- Free buffers after audio transmission in the driver
- Perform buffer reload for DMA after every reception/transmission
- Removed unused Kconfig variables
- I2S_CAVS_TX_BLOCK_COUNT
- I2S_CAVS_RX_BLOCK_COUNT

Added a mechanism to refresh DMA buffers without the
need to call the "configure" API every time.
The reload is done after every DMA completion.

Config API is meant for initial configuration.
Using config API to reload DMA buffers is inefficient and hence
a reload API is added

Tty device gets only read/write calls, but console retains
getchar/putchar for convenience.
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
Previously, transmit was effectively non-blocking - a character either
went into buffer, or -1 was returned. Now it's possible to block if
buffer is full. Timeout is K_FOREVER by default, can be adjusted
with tty_set_tx_timeout() (similar to receive timeout).
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
This allows to specify receive timeout, instead of previously
hardcoded K_FOREVER value. K_FOREVER is still the default, and can
be changes after tty initialization using tty_set_rx_timeout() call,
and timeout is stored as a property of tty. (Instead of e.g. being
a param of each receive call. Handling like that is required for
POSIX-like behavior of tty).

If we don't have Newlib, the more or less POSIX library, it's unclear

This is simplistic implementation which just redirects to (likewise
simplistic) implementation in lib/libc/newlib/libc-hooks.c. This
should be replaced with bindings to "real console", but what should
be a "real console" is so far discussed, at the RFC stage.
This implementation goes into the fdtable.c itself to keep all those
things nicely static. (This is again likely will change when we have
"real console", but again, it's so far not clear where it would
belong, so at least avoid creating random files to be deleted later).

Previously the "socket file descriptors" were just net_context
pointers cast to int. For full POSIX compatibility and support
of generic operations line read/write/close/fcntl/ioctl, the
real file descriptors should be supported, as implemented by
fdtable mini-subsys.
Socket implementation already has userspace vs flatspace dichotomy,
and adding to that ptr-fds vs real-fds dichotomy (4 possible cases)
is just too cumbersome. So, switch sockets to real fd's regardless
if full POSIX subsystem is enabled or not.

All the handling of POSIX file descriptors is now done by fdtable.c.
fs.c still manages its own table of file structures of the underlying
fs lib.
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
The table allows to wrap read/write (i.e. POSIX-compatible) semantics
of any I/O object in POSIX-compatible fd (file descriptor) handling.
Intended I/O objects include files, sockets, special devices, etc.
The table table itself consists of (underlying obj*, function table*)
pairs, where function table provides entries for read(), write, and
generalized ioctl(), where generalized ioctl handles all other
operations, up to and including closing of the underlying I/O object.

The define NRF51822 has no in-tree users and is believed to have been
added by accident. The define NRF51 should be referenced in it's
place.
To avoid users accidentally referencing NRF51822 instead of NRF51, and
to avoid confusing users into believing that NRF51822 has semantics we

The build script ext/hal/nordic/CMakeLists.txt manages the MDK
dependency. The MDK is not aware of Zephyr and uses it's own defines
to indicate what HW we are building for.
This commit moves these MDK-specific defines out of the 'soc' build
scripts and into the MDK build script where they belong.
This is expected to be a pure refactoring without side-effects.

Update menuconfig and Kconfiglib to upstream revision 68426efeae6aa, to
add two minor menuconfig improvements and a small bugfix:
- Expected errors, like syntax errors in Kconfig files, no longer
generate a Python backtrace. Just the error message is shown.
- Entering a choice now places the cursor on the selected symbol, if
any.
- Having two consecutive empty 'if's (which could also appear e.g. due
to osource) crashed the menuconfig when entering show-all mode, due
to the 'if' removal logic in Kconfiglib failing to remove one of
them. All configurations of 'if's are now correctly removed.
This error was found while reading the code.
Some minor optimizations and some internal cleanup is included as well.

k_poll_signal was being used by both, struct and function. Besides
this being extremely error prone it is also a MISRA-C violation.
Changing the function to contain a verb, since it performs an action
and the struct will be a noun. This pattern must be formalized and
followed and across the project.

This is not violating any MISRA-C rule, though, it seems to be
triggering a false (rule 9.1) positive in some static analysis
tools. Nevertheless, it is more readable declare all variables in the

Before dtc 1.4.7 we'd get something like the following for an gpios
property:

After dtc 1.4.7 we get:
cs-gpios = <0x05 0x0d 0x00>, < 0x06 0x00 0x00>;
We should handle both cases in the extract reg handling code. So if
we see a list of lists, we flatten it to a single list to normalize
the property.
