Extract the calibration code from the f0, and share it with the other
adc-v2 peripheral users (f0,l0,f3,l4)
Uses the same naming set of is/async naming conventions requested by the
RTOS guys instead of having blocking only calls.
Old code:
adc_calibrate_start(ADC);
adc_calibrate_wait_finish(ADC);
New code (blocking):
adc_calibrate(ADC);
New code (asynch):
adc_calibrate_async(ADC);
// do stuff
adc_is_calibrating(ADC); // will be false when it's finished.
Old code for f0 is still available, but marked deprecated.
This is common code for f0234, keep renaming files as has become standard, even
if it's a suboptimal solution. This doesn't rename the header which was not
renamed for f3.

The adc v2 periph has the same register map, but comes in two flavours, one
supporting injected channels, more watchdogs, per channel sampling times and
so on, and one "simple" version.
Pull up the f3 and f0 portions into the appropriate files, after comparing with
L0 and L4 reference manuals, even if those are not fully landed yet.
The f0, f30x and l0 have a very similar "v2" adc peripheral.
Start extracting out some of the common code, and fix the glaring bug in
adc_power_down that was affecting them both.
This is not intended to be a fully comprehensive extraction, just the first
easy steps.
At least temp sensor, vrefint and vbat/vlcd should have consistent names and
consistent doxygen.
Dropped channel definitions that are the same as the raw number.
As done by esden for the F4, remove typedefs and add prefixes to clock enums
This extends this to all stm32 families.
Let's not hide the fact that these variables are structs/enums.
We are filling up the namespace badly enough, we should be prefixing as
much as we can with the module names at least. As users we already run
often enough in namespace colisions we don't have to make it worse.
* CLOCK_3V3_xxx enums renamed to RCC_CLOCK_3V3_xxx
* clock enums (PLL, HSI, HSE ...) prefixed with RCC_
* scale enum of pwr module prefixed with PWR_
Many stm32 families have multiple ADC and DAC peripherals. F0 (so far) only
has one. To make it easier to use the same code on many stm32 families,
provide an alias for ADC1 to ADC.
After adding support to the f3, add missing doxygen support to the f0
equivalent. This improves things and keeps them consistent until/if they are
pulled out as common code.
TSC_IOGxCR is actually a 32 bit register, of which 13 bits are used
(rest are reserved).
Also, added x-1 since G0 is not a valid group, TSC_IOGCSR_GxE(1) is supposed
to be at 0x34, not 0x38.
All the macro arguments that are user supplied, or potentially, wrap properly
in () as good practice.
Probably missed one or two, and a lot of them are possibly unnecessary, but
it's straightforward to just do it always.
Fixes github issue #321
Based on previous work, add a new driver for the v2 usb peripheral found on
stm32f0 and l0 devices.
Correspondingly, add a usb gadget zero test suite for the f0. L0 device level
code isn't yet ready, but will add the test case when it moves in.
Work by Frantisek Burian, Kuldeep
Singh Dhaka, Robin Kreis, fenugrec and zyp on irc, and all those forgotten.
This adds MCO source selection to some targets, and removes and standardizes
the mask/shift usage for all targets. For devices that support MCO2, this
supports only MCO1. No attempt has been made to extract MCO prescaler, which
is not available on all F1 and F3.
Rename rcc_ppre1_frequency and rcc_ppre2_frequency to rcc_apb1_frequency and rcc_apb2_frequency
Also add rcc_ahb_frequency (although it is not set correctly in all cases) which will be fixed by
the rcc commits later. Also fixup the only use in the library of these variables, the USART code.
And fix the typos that resulted
Make l1 generic too
Pulls out duplicate calls from f0/rcc.c and uses the common version which
also means that f0 can use rcc_peripheral_enable() now which is in common
but not the old rcc versions.
Latest versions of all reference manuals refer to the address as SPIx_BASE, and
simply name some of the individual registers as SPI_I2SXXXX. Likewise, the
interrupts are simply SPIx, not SPIx/I2Sx. Rather than hacking more duplicates
into the F0 and L0 parts where this was turning up, remove the pointless _I2S_
from SPI2/SPI3 and make it all consistent
Compile tested only, with the examples collection.

Fixes#331Fixes#347
This commit has been based on kuldeepdhaka's pioneer work, but it was reformatted to apply libopencm3 inclusion tree correctly.
timer_common_all.c now supports new rcc_periph_reset_pulse function for all families.
to remove variations, redundancies, add missing, fix errors. All c files
refer only to the dispatch style headers in /include/stm32. Those headers
#include memorymap.h and cm3/common.h. All references to
these are removed from the family specific headers. Ethernet untouched as
it appears incomplete.
Added dummy spi.c for F0/F3. Fix some doxygen anomalies.
When compiling with all warnings enabled, some defines can lead to
warning due to missing unsigned type suffix:
warning: integer overflow in expression [-Woverflow]
This fix should not affected behavior at all, since calculation with
such overflows lead to the same actual address when writing to that
location. However, it makes the warning disappear and also defines
the right data type for a memory location.
Extension of code for STM32F1 to allow for dual bank series XL.
Small changes to documentation for F2, F4 and L1 to add a parameter reference.
Tested with STM32F103RBT6
(note: tests show that the PG bit must be cleared after programming, otherwise
a subsequent erase attempt fails. This has been added to flash_program_half_word
for F0 and F1 only. A fix for the other families is not included in this PR.)
So that the navigation pane works correctly in browsers.
Some additional doc fixes put in where found (but many more still to go).
Added some dummy .c and .h files to bring the associated docs into line.
makefile changed to allow 'make html' as well as 'make doc' (the latter only does html anyway).
This converts all the YAML files to JSON files, as json parsing is built
into python instead of being a separate library requiring installation.
YAML is a superset of JSON, but putting comments in is not quite as obvious
as it is in yaml.
The following glue was used to convert yaml to json:
python -c 'import sys, yaml, json; json.dump(yaml.load(sys.stdin), sys.stdout, indent=4)' < $1 > $2
Clearly I haven't tested this on every single platform, and this
doesn't address the large blobs of yaml in the lpc4300 scripts directory,
only the cortex NVIC generation process.
I've tested a few IRQ driven example apps, and I've checked the generated
output of some known cases like the LM3s that has explicit gaps, and they are
all generated correctly.
The value '6' was twice in the table and all higher frequencies are
shifted. The values are now fitting the table in 'STM32F05xxx/06xxx advanced
ARM-based 32-bit MCUs', page 101.
PLL frequencies have been measured by selecting
rcc_set_mco(RCC_CFGR_MCO_SYSCLK);
and measuring the output with an oscilloscope. 8, 16, 24, 32, 40 and 48 MHz
work fine from the HSI base.
