fix uart_sam0_irq_update to only clear the RXS bit by writing only the
RXS bitflag to the INTFLAG register. Performing an |= opperation
with the bitflag for RXS incorrectly clears all pending interrupts set
since writing 1 to a INTFLAG clears that bit field. This causes a race
condition on when TXC will be cleared before all bytes have finished
being clocked out on tx and TXC being set 1 again. If tx finishes first,
any driver using uart_irq_tx_complete will deadlock the system.

sam0 does not currently have a uart_irq_tx_complete method for interrupt
driven mode.
This is especially important since the sam0 platform has seperate
interrupt signals for TX data register empty and TX complete therefore
the TX register being empty does not nessisarily mean the data has been
shifted out.
Drivers should check uart_irq_tx_complete if it needs to guarantee
that the data has been fully transmitted in a hardware agnostic way.

Aim of this change is to remove the need for the pinmux driver
on stm32f1 series to access the base address of the pinmux owner
device.
This is achieved by a modification in the device tree pin definition.
Instead of providing a generic information on type of the remap
(such as NO_REMAP, PARTIAL_REMAP, FULL_REMAP), the remap field
encodes all the information required to perform the remap register
configuration:
-Address of the targeted remap register in AFIO peripheral
-Position of the remap configuration in the remap register
-Mask used for the remap configuration encoding
-Value of the expected remap configuration.
All the possible remap configurations are encoded and predefined
in a new stm32f1-afio.h dt-bindings include.
To match this new configuration, all stm32f1 -pinctrl.dtsi should
be regenerated to use these new remap definitions.

Extends STM32 PWM driver to support capturing pulse width, period,
or both.
The approach used is based on the PWM Input sections in reference
manual RM0351 by ST in the chapters on timers.
The LL library by ST is used for all extensions to the driver.
Only the disco_l475_iot1 board was available for testing on hardware,
using tests/drivers/pwm/pwm_loopback.
Since timers are a generic component, it is assumed that other STM32
boards will behave the same

HTS221 is a humidity and temperature sensor (thus HTS) that can be wired
on i2c or SPI bus. On SPI bus however, it uses the 3-wire mode, aka:
half-duplex.

on that sensor.
Let's move to a better DTS integrated driver as well, and also use

This is meant to expose half/full duplex configuration option on regular
configuration. So far, dual/quad/octal are not exactly supported, as it
would require extensions to the SPI buffer for a full support.
So moving these modes to an extended operation attribute
(32 vs 16 bits), disabled by default.
And exposing half/full duplex configuration bit. Full duplex being the
default option.

This commit fixes dual bank flash handling on stm32g0 targets.
In contrast to other Series (G4, L5) the flash page size does not change
in single bank configuration (2KiB in both configurations).
nSWAP_BANK:
While the reference manual(RM) only documents:
"This bit selects the bank that is the subject of empty check upon boot"
as expected, this behaves similar to BFB2 on G4 and SWAP_BANK on L5.
It has been observed that this bit swaps the address mapping of bank1
and bank2, regardless of DUAL_BANK bit being set or not.
As documented in the RM the nSWAP_BANK bit is ignored when the BOOT_LOOK
bit is set. This applies to the empty check as well as the address
mapping.
On this Series FLASH_CR_BKER must be set in single-bank as well as
dual-bank configuration for erase operations on bank2 regardless of
the swap status.
On a G0B1RE (dev-id: 0x467) I could not observe a difference between
DUAL_BANK flash option bit set and not.
It this may be different on 256KiB Flash targets.
The HAL indicates that "FLASH_SALES_TYPE_0" only uses a single bank if
OB_DUAL_BANK_VALUE is not set, but as I don't know which SoC this is
and I can't test the behaviour and the driver does not take this into
account.

This commit makes no functional changes, it only refactors the
driver such that dual bank flash handling can be easily added.
Instead of using HAL macros directly in the code, new macros
with STM32G0 prefix are defined.
The erase_page function gets passed the offset instead of the page,
and the FLASH CR reg is written once with all erase parameters.
flash_stm32_wait_flash_idle is already called before each
write to CR, consequently it is also made sure CFGBSY flag
is not set.
Signed-off-by: Thomas Stranger <thomas.stranger@outlook.com>
Some series (namely g0, u5, wb, wl, ?) use CFGBSY to indicate
that FLASH_CR is not ready to be modfied.
This commit adds this flag additionally to other the flash busy flags,
in flash_stm32_wait_flash_idle such that the driver waits before
trying to modify PG, PNB[6:0], PER, and MER bits in FLASH_CR.
Additionally, dual bank variants of STM32G0 have a seperarate BSY2 flag
for flash bank two.
Until now this was not yet checked in flash_stm32_wait_flash_idle.

In STM32G0 HAL FLASH_FLAG_xxx defines don't follow the pattern of
other Series to simply redefine the FLASH_SR_xxx Msk.
Instead an ID for the SR reg and the position of the Error flag
are defined.
As a result error checking in flash_stm32_check_status was not working
until this fix on stm32g0 series.
In order to avoid complexity in the driver, the ifdef-ery of the flags
was moved to the header file.
Other series except g0 use FLASH_FLAG_xxx defines, because those
are valid for both cores in dual core(wl) and in secure/non-secure
targets(l5,u5).
FLASH_STM32_SR_ERRORS mask is introduced to check for any active error
in the SR.
The flags for SIZERR, MISERR, FASTERR are newly introduced.
the latter two are only required once fast programming is used,
which is not yet the case for any series.
The FLASH_SR_OPTVERR flag (option validity flag) is also present
in the SR, but is not added.
Also ecc errors are generally not checked, but these are in a different
register.

An attempt to simplify the ifdef-ery around FLASH_SR is made.
Define Registers and flags in the header file instead of including
several individual operations in the driver.
FLASH_FLAG_BSY is not only defined for STM32L5, but also other series.
Therefore use this flag instead of FLASH_SR_BSY.
Only the g0 series definition is not valid in our context,
therefore use FLASH_SR_BSY1 instead.

Refactors all of the on-chip GPIO drivers to use a shared driver class
initialization priority configuration, CONFIG_GPIO_INIT_PRIORITY, to
allow configuring GPIO drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.
Most drivers previously used CONFIG_KERNEL_INIT_PRIORITY_DEFAULT or
CONFIG_KERNEL_INIT_PRIORITY_DEVICE, therefore the default for this new
option is the lower of the two, which means earlier initialization.
Driver-specific options for off-chip I2C- or SPI-based GPIO drivers are
left intact because they often need to be initialized at a different
priority than on-chip GPIO drivers.
