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
More could probably be found, but this makes some of the basic RCC defines for
the L0 much more inline with other platforms, and much less verbose. This
helps us have more identical code for library users across different targets.
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.
The breaking changes here changes in header location, and changes in driver
name passed down to the usb stack.
Changes affect: stm32f102/f103, stm32l1, and some f3 parts
* instead of the confusingly generic "usb" use the name "st_usbfs" for the USB
Full speed peripheral ST provides in a variety of their stm32 products.
Include directives should change as:
#include <libopencm3/stm32/usb.h> => <libopencm3/stm32/st_usbfs.h>
* instead of the confusingly specific "f103" name for the driver, use
"st_usbfs_v1" [BREAKING_CHANGE]
Instead of:
usbd_init(&stm32f103_usb_driver, .....) ==>
usbd_init(&st_usbfs_v1_usb_driver, .....) ==>
The purpose of these changes is to reduce some confusion around naming, but
primarily to prepare for the "v2" peripheral available on stm32f0/l0 and some
f3 devices.

* USB host register definitions added.
* Extracted common register and bitfield definitions
from 'otg_fs.h' and 'otg_hs.h'
into new file 'otg_common.h'.
Modified usb low-level drivers to adopt to new style of bitfields.
* Fixed typo OTG_GOTGIN -> OTG_GOTGINT (according to the datasheet)

All STM32 family pwr.h must use LIBOPENCM3_PWR_H as include guard so that
pwr_common.h can detect that it has been referenced by pwr.h for
each family. F2 and F3 had the wrong include guard.
Fixes Github issue #513
This removes the shift from the defines, and includes them in the helper
function, making the code match the documentation, and following how the
rest of the library commonly operates.
Code using the existing defines will continue to work.
Basic helpers to at least support common configurations for the f401.
Original submission specified 5 wait states, but the reference manual and other
reviewers all believe that 2ws is sufficient for these modes.

The f3 adc has separate bits for end of conversion and end of sequence.
Support those fully, with the regular enable/disable irq methods, and
the flag checking methods.
Discovered in github bug: #493
This code was copied from the f4, and blindly modified to make it seem
to work. The f3 has separate flags for EOC and EOS, it doesn't use a
second bit to configure what the EOC bit does.
Consequently, update the documentation to correctly indicate that the
EOC bits are only set per conversion.
Discovered in github bug: #493
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.
When writing the USB endpoint register, USB_EP_RX_CTR (bit 15) and
USB_EP_TX_CTR (bit 7) should be set to avoid inadvertently clearing
either bit.
Prior to this patch end points could indefinately stall if the hardware
changed these bits between the time they are read and when they were
written.
