df15b263d2 usb: hid: add a stub file for doxygen
Unlike with the doxygen source generation, we can't autoguess which of
the class files are eligible automatically.  Instead, make a stub hid
file, (which we can now start adding to, if desired) and include it in
all builds that include other class stubs.

2035d84e55 stm32: lptim: add base support
Add basically what's needed to have some minimal but usefull subset of
function for a timer: irqs, compare, period, out polarity, enable/disable

Consistent with all others.  The separation of the common and specific
portions is unnecessary and misleading.

9904f9803e doc: stm32: unify "peripheral API" titles
doxygen really wants the @defgroup _and_ the @addtogroup to both have
the full name, matching identically, to avoid all warnings.

Standardize on the "CAPS_PERIPH peripheral API" style.

7be50a5e75 make: use $(PREFIX)gcc instead of $(PREFIX)-gcc
The leading - makes it rather inconsistent with the majority of other
projects around the world.  Use the form everyone else uses.
To solve this, properly pass prefix to inner makes as was always
intended.

only documenting common code, but not specific code.  Delete dummy .c

ddc7ab8c6c stm32l4: flash: don't use misleading names
flash_clear_pgperr_flag is a name used on f247, which is actually most
analogous to the SIZERR bit on l4, (it's a parallelism error)

the bit being cleared originally in this function, PROGERR is a new bit,
and should have it's own name.

Add a function to handle the previously unhandled size/parallelism flag,
and rename the existing one to properly reflect it's new name.

Turns out, there's lots of common code for flash.  Pull up prefetch
on/off to start with, as there's only a single bit name different.

Pull up the definitions of common API functions too, starting with
flash_set_ws.  Even if the implementations are different, things that
meant to be the same, should be defined centrally.

b47b967440 doc: use common naming for peripheral apis
Only applied to STM32 doc trees at present.

Instead of declaring a group for "STM32blah" in the doc-blah.h files,
and then trying to put all the common+specific peripheral code into
those groups, (which is what led to the stub doxygen holder empty .c
files)  Just use a standard name like "Peripheral APIS" and place
everything into that.

Demonstrated by converting ADC and USART peripherals, which is
definitely not complete, but it shows how to make things less magical,
and less prone to copy/paste errors.  Now, you can copy/paste and it
will do the right thing, because everyone uses the same group names.

This is also how to unify the mix of "STM32blah->Periphblah" and _also_
the dangling "periph_file" modules in doxygen, it merges them together
properly, as they're intended to be really.

bf125e91f9 stm32: rework spi, based on PR #740 and #742.
split spi stuff in three part:
 - v1 : basic spi peripheral
 - v1_frf : v1 spi with frf mode additional bit in spi_cr2 / spi_sr
 - v2 : spi with variable datasize, fifo and other fancy stuff.

v1 maps to f1 chips
v1_frf to f2, f4 and l0,l1
v2 to f0, f3 and l4

This breaks spi_master_init API for v2 devices : function prototype from
common spi header used to be abused, with DFF bit reused for CRCL bit.
New v2 spi_master_init does not handle anymore CRCL bits, as it does not
usually mess with other crc configuration.

9a05dcb6c0 ld scripts: drop duplication of standard sections
Instead of every "simple" target having their own duplicate file with
all the section mappings, just provide a single, simple,
"cortex-m-generic.ld" that works with our startup code and any simple
rom/ram system.  This also drops the pointless copying of files all over
the place.  Using -L flags properly is sufficient, and the standard file
is now in the root of the library already.

According to reference manuals both l0 and l4 have "v2" i2c peripheral.
This patch adds i2c support to l0 and l4 using previously unified "v2" i2c

No real hardware has been tested so far. Only compilation tests for both
libopencm3 and libopencm3-examples for all stm32 families.
