V=s is openwrt, V=1 is here.
try and avoid weird problems with missing files like,
make[1]: *** No rule to make target '../../../include/libopencm3/stm32/g4/pwr.h', needed by 'rcc_common_all.o'. Stop.
by turning down the paralellism a bit, it's a quad core arm, but it's
stil a little small machine.
The order of the UCPD1 and UCPD2 bits as described by the
rcc_periph_clken and rcc_periph_rst enums is swapped with regard to the
datasheet. Swap them.
Fixes: https://github.com/libopencm3/libopencm3/issues/234
uses the new mechanisms introduced to address a similar problem on F7.
Tested on a medium density part (0x429) that returns the same ids as
before, tested on a high density part that now _doesnt_, but that's now
correct :)
Reduced the sea of enums, and renamed config parameters to match other
implementations, cribbing off of the G0 config, as it is closer to the level
of complexity. Updated initialization code to utilize the new values.
Added flash and LDO configuration from RCC init to be more consistent with
STM32 platform initialization.
PLL configuration on the H7 is pretty involved, and takes a number of
configurations to make it work. In order to make peripheral drivers a bit
easier to implement, working with a soft clock tree in the rcc module which
stores the clock settings for each clock as they are setup such that users
can request the clock value from the RCC module for configuration. Added
getter for the clock which allows the user to pass the base address of the
peripheral, and get the peripheral clock value for convenience.
Clock configuration is still missing values for setting up all of the kernel
clocks for the peripherals, but this is in work, and there is a framework to
do so.
Have tested to 400MHz without issue. Peripherals that are explicitly supported
are working and the clock tree values appear to follow correctly.
Added LDO settings to allow setting the scaling to support high frequencies.
In this commit, support for the different base addresses for different
F7 parts is added, but the mechanism is now in place for L1 and others.
