c6829fa5b8 sdmmc: improve error handling during SPI mode init
- In SPI mode, the card will respond to the initial SDIO reset (done
using CMD52) with “invalid command” error. Handle this correctly.

- sdmmc_card_init had a hack where GO_IDLE_STATE (CMD0) command was
sent twice. Add explanation why this is done, and don’t expect
correct response from the card on first CMD0.

- improve logs printed at debug level by adding CMD index

ee600784c5 sdmmc: add SDIO support
- Add SDIO support at protocol layer (probing, data transfer, interrupts)
- Add SDIO interrupts support in SDMMC host
- Add test (communicate with ESP32 in SDIO download mode)

20a8c3318a sdmmc: do expect CMD_DONE interrupt after response timeout
Existing code assumed that response timeout is not followed by CMD_DONE,
which was not true, in fact. Host datasheet states that CMD_DONE is sent
after an RTO.

5fc6fb58ea sdmmc: don't whitelist the opcodes when handling response timeout
All the commands which do not have a response must have their flags set
accordingly. Therefore the host will not send RTO interrupt if response
is not expected. It is a bug in the code logic if it happens otherwise.

f02cff13cc sdmmc: set highest possible host clock divider
SDMMC host suffers from an issue that it outputs data near the rising
edge of the card clock, which is the edge used by the card to sample
data. If sampling time constraint is not satisfied, card may read data
after the transition.

The phases of output/input data can, in fact, be adjusted. However this
adjustment happens in the clock generation block outside of the host.
So the maximum phase change which can be created this way is equal to
half of the host clock period. So if the host clock is set to the lowest
possible frequency (for the given card frequency), then the phase offset
(and hence the hold time) will be the highest. This change modifies the
logic used to determine clock dividers accordingly.

sdmmc host: set correct dout phase and print correct frequency

84d6793f77 sdmmc: don't set data_expected on SET_BUS_WIDTH command
SET_BUS_WIDTH is not a data transfer command. Extensive search in the
host datasheet and SD card spec did not reveal the origin of this hack
or 'feature'. Further testing showed that removing this does not lead to
regressions.

3d89c8ba74 rmt: Fix LoadProhibited on RX END
Fixes exceptions LoadProhibited, when rmt tries read variable p_rmt on RX END which can be 0.
It happens after esp_reset()  (OTA) and the rmt is not probably stopped by it.
In other words the routine rmt_driver_isr_default was called before second rx channel was registered.

scenario:
register tx channel
register rx channel
reboot
register tx channel
-> exception (because rx channel is accessed)

4a2489b99a sdspi: fix compatibility issue in multi block read
SDSPI driver optimized polling of the response tokens by requesting
two extra bytes on top of the block size (512) and CRC (2), and
checking whether these bytes contained the data response token or
not. In case the token was there, further polling would not need to
happen, thereby reducing latency between two consecutive blocks
transferred. However this caused compatibility issues when these two
extra bytes were sent after reading the final block. When
STOP_TRANSMISSION command was sent, these extra two bytes were
treated as part of the command, causing an invalid command error.

This fixes the logic by only requesting extra two bytes if the block
being read is not the final block. In addition to that, more strict
error checking is implemented for command response tokens.

bbbdec24d9 sdspi: handle error flags for R3/R7 responses
Previously error flags were only handled for R1 responses. This change

86a1d579ff docs: add warning to gpio_get_level()
On most microcontrollers I have worked with one can retrieve the
current state of output GPIO pins. On ESP32 this is not the case
if the pad is not explictly configured to route this information into
the port by configuring it as input or i/o.
Thus add a warning to the API documentation of gpio_get_level().

4297c337f9 esp32: Add IO_MUX_GPIOxx register names to match iomux names used in TRM
The TRM describes IOMUX registers are IO_MUX_x_REG for x in GPIO0-39.

Until now ESP-IDF describes them as PERIPHS_IO_MUX_(pinname)_U

This commit adds additional IOMUX register names which match the ones used in the TRM.
