Currently CMSDK uart_irq_is_pending does not use RX and TX interrupt
bits found in INTSTATUS register to check for pending interrutps but
rather it checks for pending interrupts indirectly by checking if RX and
TX buffers are, respectively, full and empty, i.e. it checks bits 0 and
1 in STATE register instead of bits meant for interrupt status found in
INTSTATUS register.
That is particularly problematic because although a RX interrupt implies
a RX buffer full and a TX interrupt implies a TX buffer empty, the
converse is not true. For instance, a TX buffer might be empty for all
data was processed (sent to serial line) already and no further data was
pushed into TX buffer so it remained empty, without generating any
additional TX interrupt. In that case the current uart_irq_is_pending
implementation reports that there are pending interrupts because of the
following logic:
/* Return true if rx buffer full or tx buffer empty */
return (UART_STRUCT(dev)->state & (UART_RX_BF | UART_TX_BF))
!= UART_TX_BF;
which will return 1 (true) if STATE[0] = 0 (TX buffer is empty), since
UART_TX_BF = 1, so STATE[0] != UART_TX_BF, which is true (assuming here
for the sake of simplicity that UART_RX_BF = 0, i.e. RX buffer is empty
too).
One of the common uses of uart_irq_is_pending is in ISR in contructs
like the following:
while (uart_irq_update(dev) && uart_irq_is_pending(dev)) {
if (uart_irq_rx_ready(dev) == 0) { // RX buffer is empty
continue;
}
// RX buffer is full, process RX data
}
So the ISR can be called due to a RX interrupt. Upon finishing
processing the RX data uart_irq_is_pending is called to check for any
pending IRQs and if it happens that TX buffer is empty (like in the case
that TX interrupt is totally disabled) execution gets stuck in the while
loop because TX buffer will never transition to full again, i.e. it will
never have a chance to have STATE[0] = 1, so STATE[0] != UART_TX_BF is
always true.
This commit fixes that undesirable and problematic behavior by making
uart_irq_is_pending use the proper bits in the interrupt status register
(INTSTATUS) to determine if there is indeed any pending interrupts.
That, on the other hand, requires that the pending interrupt flags are
not clearly automatically when calling the ISR, otherwise
uart_irq_is_pending() will return immediatly false on the first call
without any data being really processed inside the ISR. Thus, because
both RX and TX buffer (FIFO) are only 1 byte long, that commit clears
the proper interrupts flags precisely when data is processed (fifo_read
and fifo_fill) or when the interrupts are disabled (irq_rx_disable and
irq_tx_disable).
Finally, that commits also takes the chance to update some comments,
specially regarding the need to "prime" when enabling the TX interrupts
(in uart_cmsdk_apb_irq_tx_enable()). The need to "prime" can be verified
in the CMSDK UART reference implementation in Verilog mentioned in the
"Arm Cortex-M System Design Kit" [0], on p. 4-8, section 4.3,
in cmsdk_apb_uart.v. In that implementation it's also possible to verify
that the FIFO is only 1 byte long, justifying the semantics that if
buffers are not full (STATE[0] or STATE[1] = 0) they are _completly_
empty, holding no data at all.

The "spi-max-frequency" property already exists, but was unused. This
now sets the SPI clock frequency to this value (limited to 24MHz) once
initialisation is complete.
Due to the nature of the SPI API, it is necessary to have two separate
configuration structures to switch clock speed as some SPI drivers only
compare pointers to detect changes.

Before this change, the sw reset did not work after power-on, because
I2C commands are only accepted after 20msec (t_START after power-on).
Now the 20msec delay is moved before performing the reset to ensure that
the SW reset command can be executed. An additional 2msec delay is added
after the reset (see datasheet t_START after reset).
