Jim Mussared 94beeabd2e py/obj: Convert make_new into a mp_obj_type_t slot.
Instead of being an explicit field, it's now a slot like all the other
methods.

This is a marginal code size improvement because most types have a make_new
(100/138 on PYBV11), however it improves consistency in how types are
declared, removing the special case for make_new.

yn386 989b8c728b stm32/timer: Fix use of timer channel callback() method on L4 MCUs.
Since L4 HAL version 1.17.0, HAL_TIM_IC_Start_IT() checks whether specified
channel of timer is busy or not, which is the case if this function is
called more than once without first calling HAL_TIM_IC_Stop_IT().  The fix
in this commit is to call the stop function before calling start.  The PWM
and OC modes have the same issue with the same fix.

Fixes issue #8732.

This commit adds mp_raise_msg_varg(type, fmt, ...) as a helper for
nlr_raise(mp_obj_new_exception_msg_varg(type, fmt, ...)).  It makes the
C-level API for raising exceptions more consistent, and reduces code size

The period of the timer can now be specified using the "period" and
"tick_hz" args.  The period in seconds will be: period/tick_hz.  tick_hz
defaults to 1000, so if period is specified on its own then it will be in
units of milliseconds.

Damien George cb3456ddfe stm32: Don't use %lu or %lx for formatting, use just %u or %x.
On this 32-bit arch there's no need to use the long version of the format
specifier.  It's only there to appease the compiler which checks the type
of the args passed to printf.  Removing the "l" saves a bit of code space.

Damien George a03e6c1e05 stm32/irq: Define IRQ priorities directly as encoded hardware values.
For a given IRQn (eg UART) there's no need to carry around both a PRI and
SUBPRI value (eg IRQ_PRI_UART, IRQ_SUBPRI_UART).  Instead, the IRQ_PRI_UART
value has been changed in this patch to be the encoded hardware value,
using NVIC_EncodePriority.  This way the NVIC_SetPriority function can be
used directly, instead of going through HAL_NVIC_SetPriority which must do
extra processing to encode the PRI+SUBPRI.

For a priority grouping of 4 (4 bits for preempt priority, 0 bits for the
sub-priority), which is used in the stm32 port, the IRQ_PRI_xxx constants
remain unchanged in their value.

This patch also "fixes" the use of raise_irq_pri() which should be passed
the encoded value (but as mentioned above the unencoded value is the same
as the encoded value for priority grouping 4, so there was no bug from this
error).

Damien George e37b8ba5a5 stm32: Use STM32xx macros instead of MCU_SERIES_xx to select MCU type.
The CMSIS files for the STM32 range provide macros to distinguish between
the different MCU series: STM32F4, STM32F7, STM32H7, STM32L4, etc.  Prefer
to use these instead of custom ones.

Damien George 3eb0694b97 stm32: Update HAL macro and constant names to use newer versions.
Newer versions of the HAL use names which are cleaner and more

Damien George d29b709642 stm32/timer: Enable ARPE so that timer freq can be changed smoothly.
The timer prescaler is buffered by default, and this patch enables ARPE
which buffers the auto-reload register.  With both of these registers
buffered it's now possible to smoothly change the timer's frequency and
have a smoothly varying PWM output.

Damien George d7cd1d2027 stm32/timer: Make pyb.Timer() instances persistent.
Prior to this patch calling pyb.Timer(id) would always create a new timer
instance, even if there was an existing one.  This patch fixes this
behaviour to match other peripherals, like UART, such that constructing a
timer with just the id will retrieve any existing instances.

The patch also refactors the way timers are validated on construction to
simplify and reduce code size.
