39843617cb drivers: modem: WNCM14A2A select UART_INTERRUPT_DRIVEN
Modem driver for WNCM14A2A was erroneously leaving the
selection of UART_INTERRUPT_DRIVEN up to CONSOLE_HANDLER.
Now, with the move to the new SHELL backend, this is no
longer happening.

Let's select it from the modem driver, instead of depending
on it.

Let's also add a dependency on SERIAL_SUPPORT_INTERRUPT
which the serial drivers enable to let us know
UART_INTERRUPT_DRIVEN is available.

5f09eae7a1 kconfig: Hide the DesignWare SPI driver on unsupported platforms
When users are configuring applications they are given the option
to enable the DesignWare SPI driver. But they should not be given this
option on SoCs that don't have the DesignWare SPI HW.

This commit hides the driver by default by introducing the config
option HAS_SPI_DW.

6194b7676c drivers: flash: add flash driver support for Atmel SAM E70
This patch adds a flash driver for the Atmel SAM E70 SoC. The driver has
been kept simple by considering that the flash is only composed of 8-KiB
blocks. Indeed an area at the beginning of the flash might be erased
with a smaller granularity, and the other blocks can also be erased with
a higher granularity. It also only handles the global read/write
protection, not the 128-KiB lock regions. A write error is returned if
a region is locked.

759b987f72 drivers: serial: Update cc32xx uart interrupt handling
The Zephyr console and shell interrupt processing assumes
a TX interrupt is evoked upon first enabling the TX
interrupt via uart_irq_tx_enable.

This was not the case with the cc32xx uart, coming out of
reset, with FIFO's disabled.

The only way found to achieve this behavior is to fill
the fifo with a non-printable character on initialization.

Also, the uart driver was explicitly clearing TX/RX interrupts in
its isr, which was unnecessary, as the act of reading/writing
did that implicitly.

These fixes allow the cc32xx uart to work with the
current Zephyr console/shell design.

49bb163756 drivers: serial: uart_cmsdk_apb: Fix interrupt-driven operation
1. There's an expectations that TX ready (i.e. TX buffer space
available) interrupt is a level interrupt, i.e. always active
while there's TX buffer space available. In particular, there's
an expectation that after uart_irq_tx_enable(), the TX interrupt
will immediately fire (assuming free TX buffer space is available).
But CMSDK UART interrupt appears to be edge interrupt, firing only
on buffer state change. So, after irq_tx_enable(), we need to
"bootstrap" interrupt processing by calling user-defined ISR
manually (the ISR will see that TX ready to accept a new char,
will write it there, then we'll get interrupt once TX buffer is
ready again).

2. Interrupts should be acknowledges only after user ISR is called,
because the ISR will check the status of interrupts.

3. Update stale comments.

87e5493167 drivers: flash: add a generic spi nor flash driver
This driver is inspired from the w25qxxdv SPI NOR flash driver which was
already implementing the CFI (Common Flash Interface) for its purpose.
To handle other NOR flash a flash id table (as Linux do) which contains
the geometry for a few SPI NOR flash based on their JEDEC ID has been
introduced.
We currently support the following flash:
 - W25Q80
 - W25Q16
 - W25Q32
 - S25FL216K
 - MX25UM512

The read and write functions are able to handle more then one page at a
time and return the number of bytes read or write.
Also because every NOR flash expect to disable the write protection
before writing or erasing, the write enable command is now part of the
write and erase functions.

39b2a09f38 drivers/timer: New xtensa timer with tickless support
Rewritten Xtensa CCOUNT driver along the lines of all the other new
drivers.  The new API permits much smaller code.

Notably: The Xtensa counter is a 32 bit up-counter with a comparator
register.  It's in some sense the archetype of this kind of timer as
it's the simplest of the bunch (everything else has quirks: NRF is
very slow and 24 bit, HPET has a runtime frequency detection, RISC-V
is 64 bit...).  I should have written this one first.

Note also that this includes a blacklist of the xtensa architecture on
the tests/driver/ipm test.  I'm getting spurious failures there where
a k_sem_take() call with a non-zero timeout is being made out of the
console output code in interrupt context.  This seems to have nothing
to do with the timer; I suspect it's because the old timer drivers
would (incorrectly!) call z_clock_announce() in non-interrupt context
in some contexts (e.g. "expiring really soon").  Apparently this test
(or something in the IPM or Xtensa console code) was somehow relying
on that on Xtensa.  But IPM is a Quark thing and there's no particular
reason to run this test there.

f04f797c2b drivers/timer: New, tickless-capable RISC-V machine timer driver
Rewritten driver along the lines of all the other new drivers,
implementing the new timer API.  Structurally, the machine timer is an
up-counter with comparator, so it works broadly the same way HPET and
NRF do.  The quirk here is that it's a 64 bit counter, which needs a
little more care.

Unlike the other timer reworks, this driver has grown by a few lines
as it used to be very simple.  But in exchange, we get full tickless
support on the platform.

Fixes #10609 in the process (the 64 bit timer registers are unlatched
for sub-word transfers, so you have to use careful ordering).
