f49150cab6 arch: arm: nrf: Rename nrf5 SoC Family to nrf
Upcoming Nordic ICs that share many of the peripherals and architecture
with the currently supported nRF5x ones are no longer part of the nRF5
family. In order to accomodate that, rename the SoC family from nrf5 to
nrf, so that it can contain all of the members of the wider Nordic
family.

422bc240b4 soc: nrf5: Use i2c configure options generated from dts
SoC dts fixups are added and the i2c_nrf5 driver is modified to use
the values generated from the device tree.

The I2C_*_DEFAULT_CFG and I2C_*_IRQ_PRI options are removed from board
defconfigs. Bitrate and IRQ priority are configured using using the
device tree instead.

HAS_DTS_I2C is selected on all nrf5 boards to prevent generation of
conflicting defines from Kconfig.

12f8f76165 Introduce cmake-based rewrite of KBuild
Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.

Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.

This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.

For users that just want to continue their work with minimal
disruption the following should suffice:

Install CMake 3.8.2+

Port any out-of-tree Makefiles to CMake.

Learn the absolute minimum about the new command line interface:

$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..

$ cd build
$ make

We need to disable and enable the Buffer TxE and RxNE interrupt
inside the EVENT ISR. The LL_I2C_{Enable,Disable}IT_TX and
LL_I2C_{Enable,Disable}IT_RX functions, used now, enable and
disable both Buffer and Event interrupt. This patch uses the
LL_I2C_EnableIT_BUF and  LL_I2C_DisableIT_BUF functions to
enable and disable the Buffer interrupt (TxE, RxNE).

to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.

We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

Enable arc to access the i2c controller on I/O fabric.

X86 cpu is only able to access the i2c controller on the I/O

arc to access both controllers. But, the existing code only
gives arc access to the controller in the sensor sub-system.
Let's grant arc the access to the controller on I/O fabric as
well by the following changes.

1. Add i2c_qmsi.c into arc compilation.
2. Use the already defined macros to choose interrupt numbers
   and do interrupt unmasking automatically based on the

3. Add new symbols in Kconfig including driver names for both

PRIMARY, SECONDARY, NANOKERNEL, MICROKERNEL init levels are now
deprecated.

New init levels introduced: PRE_KERNEL_1, PRE_KERNEL_2, POST_KERNEL
to replace them.

Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1,
SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug
where the documentation specified SECONDARY ran before the kernel started
up, but actually ran afterwards.

- every member of QM_INTERRUPT_ROUTER was renamed as well;
- QM_IRQ_* renamed too, mostly added _INT at the end;
- some isr functions were renamed to keep their names consistent;
- build for x86 needs to define QM_LAKEMONT, as QM_SENSOR was for ARC.

 - All registers for the I2C device.

I2C depends on the DMA which is enabled separately.

The suspend/resume functionality is implemented in
the QMSI shim layer as a fast and temporary solution,
it will be removed and migrated to QMSI later.

b0c28f2d00 drivers: i2c: fix a compilation dependency issue
Fix a compilation warning. Compilation of the i2c driver
requires QMSI dma object file. As a solution, the current
code has "selects DMA_QMSI" in i2c Kconfig. This results
in a compilation warning since "select DMA" is also
required. Adding "select DMA" and "select DMA_QMSI"
together in i2c Kconfig can solve the compilation issue.
But, this will cause the dma driver be unnecessarily
enabled. So, the solution is to fix the issue in the QMSI
part instead of in the shim driver.
