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.
The adc peripheral on F30x is the same as F0, L0 and L4. In the reference
manuals, the following names are used.
F3: CFGR (no CFGR2)
F0 and L0: CFGR1 and CFGR2
L4: CFGR and CFGR2
Moving to a single consistent name, that's more likely to be inline with future
part numbers makes it much easier to extract common driver code for the
peripheral.
While all bit defines are moved to the CFGR1 style, core register definitions:
ADC_CFGR(adc) and ADCx_CFGR are kept to match the original register name in the
reference manual.
Fixes Github issue #548
There are as many SMPRx registers are needed for channels supported, and on all
other families, the field definitions are just ADC_SMPR_SMP_XXX. For
consistency, and to avoid any confusion or duplication, use the same style here
too. Drop silly unused per channel definitions that have no purpose.
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.
Original commits, while appearing clean and tidy, hadn't even been
compile tested. Trust no-one. Not even Scully.

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_

Just the basic core common functionality gained for free by being a common
peripheral. Enough for a miniblink.
Fixes some errors in the GPIO memory map. ST's naming of AHB2 vs AHB3 is
confusing.
Values from RM0351rev1, with the correction of the duplicate TIM1_CC entry.
Only stub support so far, but this opens up the beginning of build testing.
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.
Based on the f0 support, which has identical functionality, but with doxygen
added. Bits renamed as they are only HSE prediv on some targets, and makes
things more consistent with the f0.
Fixes part of github issue #560
This function was badly copied and pasted from the f4 library, where there are
two functions, rcc_set_main_pll_hsi and rcc_set_main_pll_hse which combine
source, multipliers, dividers and other pll factors.
On F3, (not all of them, but the ones we support now), the function as
implemented has nothing to do with hsi / hse, and instead is simply selecting
the PLL multiplier.
Copypasta from f4 rcc code was only modified to shift the result, but not clear
the existing settings properly. Add mask/shift definitions and use them
properly.
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.
Was only in the (obviously out of date) documented example and as a
declaration. No implementations. Dropping immediately, but documentation
still needs further work.
Most changes are noise from doxygen.
Readme udpated to explain newer FP_FLAGS for m7
stm32f7 library is skipped if the toolchain doesn't support it yet.
GUSBCFG TRDT fields have very particular meanings, and the field should be set
depending on your bus speed. There's no 8/16bit meaning in any current
reference manual for this field.
Fixes github issue #530
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
