466c2fc7ec doc: update MAINTAINERS for *.rst reviewers
Documentation used to be confined to the doc/ folder but can now
be stored elsewhere in the code tree (/boards and /samples in particular)
Adding *.rst to the DOCUMENTATION section of MAINTAINERS

916837c22c Bluetooth: SPI: Replace Apache boilerplate with SPDX tag
There was a recent change to the license boilerplate of the entire
source tree, however as this spi.c was just recently added it missed
the change.

ac74d8b652 license: Replace Apache boilerplate with SPDX tag
Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Jira: ZEP-1457

In case the channel provides its own MTU and allocator it should be
able to store as much data as set in the MTU, based on that the code
can give enough credits to fill the entire channel MTU.

7890290e81 Bluetooth: Add HCI SPI driver
This driver acts as a pass-through, taking raw HCI data, converting
it to SPI comms and vice versa.  It works in the same way as the
existing H:4 and H:5 drivers, only it uses SPI instead of UART.

In this first release, the only BLE board which has been tested is
the X-NUCLEO-IDB05A1:

  http://www.st.com/en/ecosystems/x-nucleo-idb05a1.html

Although the current supported SPI format works like the one below,
it should be trivial to adapt it to support other chips with a
different format.

SANITY CHECK = 0x02
SPI WRITE    = 0x0A
SPI READ     = 0x0B

Tx Format:

   [HOST] {SPI WRITE}     0x00          0x00  0x00  0x00  {HCI MESSAGE ...}
   [CHIP] {SANITY CHECK}  {FLASH SIZE}  0x00  0x00  0x00  {0xFF * MESSAGE LEN}

Rx Format:

   {IRQ LINE GOES HIGH}

   [HOST] {SPI READ}  0x00          0x00  0x00             0x00  {0xFF * BYTES TO READ}
   [CHIP] 0x02        {FLASH SIZE}  0x00  {BYTES TO READ}  0x00  {HCI MESSAGE ...}

645f867444 Bluetooth: Take advantage of IS_ENABLED macro for BT_DBG
The new IS_ENABLED macro allows exposing conditionally enabled code
always to the compiler, even though it may not ultimately end up being
built. This is in particular useful for letting the compiler catch any
logging format string errors. Introduce a new BT_DBG_ENABLED macro
that c-files need to define before including <bluetooth/log.h> in
order to choose whether BT_DBG() logs are enabled or not.

When no Bluetooth logs are enabled the patch also modifies the log
macros to have the format strings checked with the help of the
__printf_like annotation and empty static inline functions.

c0a546ed33 drivers: QMSI AON counter: Simplify driver reentrancy code
With the use of the IS_ENABLED macro
(https://gerrit.zephyrproject.org/r/#/c/9882), the driver
reentrancy code is simplified:

The original const variable which used to serve the purpose of
making the build to compile out the reentrancy code when the
reentrancy configuration flag is not enabled is no longer
needed as the use of the IS_ENABLED macro achieves the same result.
Also the original 3 wrapper functions around semaphores API are
not necessary; instead, just use the semaphore API directly.

If the system's priority inheritance priority ceiling is not the same as
the highest priority in the system, it was possible for a thread owning
the mutex to get its priority lowered instead of left unchanged.

1adc58fd79 Bluetooth: Introduce a new connection parameter request callback
Introduce a new callback to bt_conn_cb that allows the application to
decide whether the accept or reject an incoming connection parameter
request. If the request is accepted the callback allows the
application to also adjust the values to what it thinks are more
appropriate.

The Zephyr Bluetooth API allows multiple registered connection
callbacks, so in principle there may be multiple le_param_req()
callbacks. It's recommended for an app to just use one (for clarity),
but if there are multiple the app is responsible for managing
potentially different requirements. In the case of multiple callbacks
each callback will receive the modified parameters in case a previous
callback modified them.
