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.
Signed-off-by: Thomas Stranger <thomas.stranger@outlook.com>
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.
No functional changes, only refactoring.

Signed-off-by: Jay Vasanth <jay.vasanth@microchip.com>
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.

In commit 918a574c88 ("clock: add k_cycle_get_64") this driver was
augmented with a count64() method to get a 64 bit cycle output from
the two-32-bit-word device registers.
Unfortunately it appeared to be trying to use a spinlock around the
two (low/high) reads to protect against overflow. But that doesn't
work: spinlocks protect against other CPU code using the same
spinlock, not against a hardware counter that is incrementing in real
time!
Thankfully there was already a count() routine in place that does a
detect-overflow-and-retry loop to solve this. Use that.

The modem sockets poll implementation does not allow
a combination of poll on modem sockets and on other sockets
like eventfd. This blocks trivial application signalling. Current
users are using a poll timeout, which needs to check if other
work needs to be done in the thread (eg: lwm2m engine).
To allow proper signalling with eventfd, the non offload poll
methods needs to work for the modem sockets.

include zero-length buffers in a buffer set used in transfers
(for example, when frames in a protocol consist of several parts,
of which some are optional). So far, the behavior of spi_context

Both DRDY and motion interrupts behaves like level signals since they
remain asserted until they're cleared. Configuring them as edge
interrupts is dangerous because if we ever miss an interrupt, it may
never get cleared and thus will never trigger again.
Treating them as edge signals seems to have no advantages, other than
being marginally simpler to implement.

nRF52-based board and a LIS3DH with both interrupts connected and
