d9c5016e08 test: add new test framework for different configurations
Paremeterized Test Framework
-----------------------------

The SPI has a lot of parameters, which works in the same process.
This framework provides a way to easily test different parameter sets.
The framework can work in two different ways:

- local test: which requires only one board to perform the test - master
& slave test: which generates two sub test items which uses the same
config set to cooperate to perform the test.

The user defines a (pair if master/slave) set of init/deinit/loop
functions. Then the test framework will call init once, then call loop
several times with different configurations, then call deinit.

Then a unit test can be appended by add a parameter group, and pass it into
a macro.

be567d3eb5 driver(rmt): Fixed some RMT related issues.
1. Add missing get function to RMT API: rmt_get_idle_level().
2. Suppress error message from rmt_wait_tx_done() if wait_time==0 (allows for polling).
3. Remove the blank lines between parameter lists.

924daf7b84 bugfix(i2c): reduce speed of I2C master bus reset routine and release SDA

1. Change bus reset to handle interrupted READ sequences.
2. Slow down I2C to 100khz during reset
3. If a SLAVE device was in a read operation when the bus was interrupted, the SLAVE device is controlling SDA.The only bit during the 9 clock cycles of a byte READ the MASTER(ESP32) is guaranteed control over, is during the ACK bit period.
If the SLAVE is sending a stream of ZERO bytes, it will only release SDA during the ACK bit period. The master(ESP32) cannot generate a STOP unless SDA is HIGH. So, this reset code synchronizes the bit stream with, Either, the ACK bit, Or a 1 bit.

e55f9c1e98 1. Slow down I2C to 100khz During Reset
I am stealing this delay coding from @jeremyherbert #2493 pr.

2. Change Bus Reset to handle interrupted READ sequences.

The current code does not handle interrupted READ cycles.

 If a SLAVE device was in a read operation when the bus was interrupted, the SLAVE device is controlling SDA.

The only bit during the 9 clock cycles of a byte READ the MASTER(ESP32) is guaranteed control over, is during the ACK bit period.

If the SLAVE is sending a stream of ZERO bytes, it will only release SDA during the ACK bit period. The master(ESP32) cannot generate a STOP unless SDA is HIGH.

So, this reset code synchronizes the bit stream with, Either, the ACK bit, Or a 1 bit.

3. fix typo

correct `sda_id` to `sda_io` in `i2c_master_clear_bus()` @ryan-ma found it.  This typo was generated when I manually edited this patch on GitHub, I should have done a Copy/Paste operation!

cfba157fdd spi_slave: add valid check for DMA buffers
The DMA cannot receive data correctly when the buffer address is not
WORD aligned. Currently we only check whether the buffer is in the DRAM
region.

The DMA always write in WORDs, so the length arguments should also be
multiples of 32 bits.

A check is added to see whether the buffer is WORD aligned and has valid
length.

435adaa22a spi_master: add check for trans len
The driver decide whether use MOSI/MISO phases according to the buffer
address together with the SPI_TRANS_USE_*DATA. However someone may assue
that these phases will be skipped when the ``length``/``rxlength`` is
set to 0. In fact it is a feature that ``rxlength`` is allowed to be
set to 0 when tx and rx have the same length, and the driver fill the
``rxlength`` to ``length``.

An error check is added when the rxlength is 0 but there is data to be
sent.

765bf674d0 i2s: add (optional) support to clear tx descriptor in underflow case
It has been observed that, in case of underflow (data unavailability) in
I2S transmission, previously filled up tx descriptors continue to get
transmitted on line, causing noise in case of audio use case.

This change adds optional `tx_desc_auto_clear` field during I2S driver intialization
than can zero initialize tx descriptor in case of underflow situation in
interrupt handler itself.

8cddfa35b8 spi: fix the crash when callbacks are not in the IRAM
Introduced in 9c23b8e5 and 4f87a62f. To get higher speed, menuconfig
options are added to put ISR and other functions into the IRAM.  The
interrupt flag ESP_INTR_FLAG_IRAM is also mistakenly set when the ISR is
put into the IRAM. However callbacks, which are wrote by the user, are
called in the master and slave ISR. The user may not be aware of that
these callbacks are not disabled during flash operations. Any cache miss
during flash operation will cause panic.

Essentially IRAM functions and intrrupt flag ESP_INTR_FLAG_IRAM are
different, the latter means not disabling the ISR during flash
operations.  New bus_config flag intr_flags is offered to help set the
interrupt attribute, including priority level, SHARED, IRAM (not
disabled during flash operations).  It introduced a small BREAK to
IDFv3.1 (but the same as IDFv3.0) that the user has to manually set IRAM
flag now (therefore he's aware of the IRAM thing) to void the ISR being
disabled during flash operations.

26626dfbf2 spi: add documents explicitly showing the executing core of the ISR
It is an ESP specific FreeRTOS feature that the ISR is always executed
on the core which calls the interrupt register function. In the SPI
driver, the function is always called in the bus initialization
function.

Hence, the ISR will be executed on the core which initialize the driver.

If the core is starved due to higher priority ISRs, or the interrupt is
disabled on the core (spinlock called, etc.), the ISR will not get
executed and SPI transactions will not be handled.

(MINOR CHANGE)

a52ab8ca87 spi_master: modify the error msg a little when over freq limit
The MISO signal will be delayed if the GPIO matrix is enabled.
However, delay also comes from the slave.

Previous code only considers the former case, and assume the frequency
limitations is only violated when GPIO matrix is used.

Now we are able to calculate the freq limit when extenal MISO delay is
given (feature introduced in 9c6c6ec34ab0641ace89aeb9b1a133eb6fae1a18).
The frequency limit is lower when the external MISO delay is large, and
the limit is likely to be violated even with IOMUX.

8bba348528 aes/sha/mpi: Bugfix a use of shared registers.
This commit resolves a blocking in esp_aes_block function.

Introduce:
The problem was in the fact that AES is switched off at the moment when he should give out the processed data. But because of the disabled, the operation can not be completed successfully, there is an infinite hang. The reason for this behavior is that the registers for controlling the inclusion of AES, SHA, MPI have shared registers and they were not protected from sharing.

Fix some related issue with shared using of AES SHA RSA accelerators.

f7749e18a8 gpio: Bitmask overflow fix in gpio_reset_pin
For pins 32 and up the BIT(nr) macro used here overflowed,
causing undetermined GPIO pins to be reset.
Example: freeing SPI device/bus where CS is on pin 33
caused debug UART to cease communication, TXD0 was
disabled.

Fixed as BIT64(nr) macro, to be used elsewhere as needed.
For example in definitions like GPIO_SEL_32..GPIO_SEL_39.

1df85e0039 nvs_flash: Version compatibility check for nvs storage
This change adds a check for compatibility between the nvs version
found on nvs flash and the one assumed by running code during nvs
initialization. Any mismatch is reported to the user using new error
code ESP_ERR_NVS_NEW_VERSION_FOUND.

0aa52057ed spi_master: enable 2 tests in CI
The test is previously disabled for the requirement of external
connection. Now the signals are connected by internal connections.
Also change the failure logic of the test.
