Early revisions of the reference manuals used different names for the
touch sense controller and firewall bits. These have now been changed
to be more in line with other families, and as these parts and bits were
new in this library, simply move forward to the current naming
convention.
Some parts used HSICLK, some used HSI. Most used NOCLK, f3 used
DISABLED. Try and move all to the shorter, simpler forms, instead of
having mixed defines for different targets for the same thing. Just
because the bits themselves are different doesn't mean we should make it
more difficult for users to port code.
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_
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.
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
Tested with a miniblink example on the l053 discovery board.
Only register definitions at this stage, no helpers.
Register definitions from RM0367r2, hopefully the biggest
superset of L0 parts.
