0d5e9f9620 drivers: soc_flash_mcux check before reading
LPC55xxx SoCs don't allow reading erased areas, the flash memory
controller (FMC) will trigger an ECC error for that area. To prevent
reading unwritten areas the low level FMC command of margin checking is
used, this will fail if the area to be read is not correctly written
(margin_check) or area is erased (blank_check).
In the case of an erased page, we return dummy data so the application
can program that area.

8ab0d153a2 drivers: wifi: esp: fix reset control logic and respect reset dts flags
wifi-reset-gpios flags were not respected so far. This means that
setting reset as active low (which is required in most cases for ESP
modules/chips) was done inside esp driver with inverted logic. Use dts
flags instead, so "active low" property is configured the same way as
for other drivers (i.e. in device-tree instead of driver).

This change also allows to configure reset as active high, in case where
ESP's nRST signal is somehow inverted on the board (behaving as RST
signal instead).

662835a798 drivers/serial/ns16550: Unbreak 64 bit MMIO addresses
PCI devices on 64 bit systems can be mapped anywhere, not just in the
lower 4G of memory.  Remove pointer size assumptions.

Also this removes the use of a struct uart_device_config to store the
(runtime) BAR address.  That struct has other stuff in it, and the
only thing we need is the single MMIO address.  It's also REALLY
confusing to have two "devconf" fields in the device storing values of
the same struct type, some fields of which are used from one of them
but some from the other!

43d84147d9 drivers/pcie: Fix BAR address size limitation
The PCI API was originally limited to 32 bit addresses.  Even though
it had code to skip over the high word in 64 bit BAR entries, it
refused to use it and returned a 32 bit value.  Some devices in the
wild have default mappings from the firmware for devices above 4G.

Also remove the "iobar" API.  It's dead code, we don't call it and we
don't test it.  IO space BAR entries are a legacy feature from way,
way back in PCI history (I genuinely have never heard of a real device
that uses them!).  And there's no difference in format between one of
these and a 32 bit "memory" BAR anyway, someone who actually had this
requirement could just use the existing API without worry.

62a13fb03b drivers: eeprom_at2x: guarantee retry until timeout
Make sure to retry at least once after the timeout elapses. Sample the
current time before starting the i2c transaction, and only give up if
the polling occurred after the timeout.

The timeout exists to allow the eeprom time to complete a write, during
which time it will nack transactions (at24) or the status register will
report busy (at25). If a transaction fails legitimately, but the 1ms
sleep overshoots the timeout expiration, we will not try again, which
fails to give the part the full grace period before declaring failure.

This is likely to happen in the last 1ms interval but also possible if
the eeprom thread is preempted. It is possible to only try once and give
up if the sleep lasts longer than the timeout, which fails to give the
part an adequate period to complete the write.

Waiting until the current time is after (not equal to) the timeout is
also important because we don't want to round up partial milliseconds if
the start time was sampled near the end of a millisecond boundary. The
timeouts of eeproms can be ~5ms.

414c773c48 drivers: gpio_nrfx: Replace atomic_set_bit_to() with atomic_and()
A call to atomic_set_bit_to() was used for clearing bits in an atomic_t
variable that stores information about allocated GPIOTE channels.
This caused an issue to be reported by Coverity, as the function treats
its first parameter as an array and it was provided with a pointer to
a singleton.
This commit replaces that call with atomic_and(), to prevent the issue
from being reported and for consistency with the way bits are set for
allocated GPIOTE channels (what is done with a call to atomic_or()).

8181eede5d drivers: spi: ensure the first byte has been loaded in the TX fast path
The SAM0 has a data register and a shift register.  Data that is
written to the data register is transferred to the shift register by
the peripheral.

On the SAMD51, the CPU is fast enough that the first data write hasn't
been transferred to the shift register by the time the next data write
occurs, causing the second write to be dropped, causing the receiver
to wait forever.

Fix by spinning until the data register is empty.

4be66bd33d Bluetooth: Fix host RX thread deadlock
Fix host RX thread being deadlocked. The deadlock occurs because the
RX thread is stuck waiting in conn_tx_alloc with K_FOREVER but if the
connection is disconnected only the RX thread can unblock it in the
handling of the disconnect event.

This commit fixes this deadlock by splitting the processing of the
disconnected event into two parts.
The part needed to unblock the RX is to release resources held by
unack'ed TX packets and mark the connection state as not connected
anymore.
The RX thread waiting for free_tx fifo and the TX thread waiting for
the bt_dev.le.pkts semaphore will both check the connected state after
having acquired them and will abort if disconnected.
The rest of the processing will be handled at normal RX thread
priority like normal.

Move the bt_recv_prio handling to the Bluetooth host when the host
has defined its own RX thread (CONFIG_BT_RECV_IS_RX_THREAD=n).
If the HCI driver has the RX thread (CONFIG_BT_RECV_IS_RX_THREAD=y),
then the responsibility to call bt_recv and bt_recv_prio correctly
falls to the HCI driver.
The helper function bt_hci_evt_is_prio() is replaced with
bt_hci_evt_get_flags() so that the HCI driver can do this correctly.
This decision to replace was made so that existing HCI drivers
maintained out-of-tree will fail at compile time with the new system.

67f106820b net: ppp: consume ringbuf until it is empty
ringbuf claim API returns pointer to contiguous area. In cases when data
in ringbuf wraps the end of internal buffer, then single call to claim
data is not enough to get all data - there is remaining part on the
beginning of internal buffer. Those remaining bytes will need to wait
for next ISR handler to trigger workqueue. Theoretically this means that
data on the beginning of ringbuf can wait there forever, or simply to
the next timeout in PPP stack when data traffic continues.

Consume data from ringbuf in a loop, stopping only when claiming results
in empty buffer. This will make sure that there is no stale data in the
ringbuf.
