fcd0f52e21 test(spi_master): add test case for 3 DMA issues with internal connection by gpio mux.
3 issues are:
1. RX buffer not aligned (start and end)
2. not setting rx_buffer
3. setting rx_length != length

also add spi release code here.

88b05f9391 esp_adc_cal: Added ADC calibration component
Added component containg API that is able to correct raw ADC readings
into a voltage in mV. Also provided a helper function that combines
the process of getting the raw ADC1 reading then converting it to a
voltage in mV. In doing so, the adc1_get_voltage() function of the ADC
driver has been deprecated. Instead there is now adc1_get_raw to obtain
the raw ADC1 reading, and adc1_to_voltage() that gets the raw reading
and converts all in one function. Functions using the deprecated
adc1_get_voltage() have also been updated to use adc1_get_raw().

Conversion is based on ADC characteristics. The characteristics are based
on the ADC's v_ref, herefore the appropriate structure and functions have
been provided to obtain the ADC characteristics.

The existing ADC driver has also been modified by adding a function to
route the internal ADC reference voltage to a GPIO allowing users to measure
it manually.

Relevant documentation has also been updated

6baf8195ee sdmmc: add support for high speed (HS) mode
By default SD cards are initialized in default speed (DS) mode. Enabling
HS mode requires SWITCH_FUNC command to be sent twice: first time to
query if the card supports switching to HS mode, second time to perform
the switch.

This change implements SWITCH_FUNC command and adds the procedure to
switch to HS mode.

f908425b13 sdmmc: introduce is_app_cmd flag, check it along with opcode
‘make_hw_cmd’ function checks opcodes in a few cases. Comparing opcode
does not tell the whole story, because for some SD commands there is are
APP commands with the same opcodes. This change introduces a flag which
indicates whether the next command is going to be an APP command.
The check for APP_SET_BUS_WIDTH command is updated to use this flag.
This fixes a bug with an unexpected STOP_TRANSMISSION command sent after
SWITCH_FUNC command, which has opcode 6, same as APP_SET_BUS_WIDTH.

e6258ac6cb sdmmc: don’t flip word order in MMC_RSP_BITS
MMC_RSP_BITS helper function had a hack that it flipped word order in
the response, assuming that response size is 4 words. This hack does not
work for responses which are not 4 words long (such as the SWITCH_FUNC
response, which is 64 words long).

This change removes the hack and the matching word order reversal code
in sdmmc driver.

ed1d084aea fix(spi_master): make the address field more intuitive to use.
The address field should be placed at the highest bits of address and slv_wr_status registers. Instead of breaking the address into two parts and fill in each register, move the address to the highest bits and write to the registers respectively.

Breaking change: if you fill-in the SPI address filed in a previous version in some way and it works correctly, you still have to rewrite the address, in a more intuitive way.

512898edee sdmmc: fix reads/writes to/from unaligned buffers
SDMMC hardware treats all buffers as aligned, and ignores 2 LSBs of
addresses written into DMA descriptors. Previously SDMMC host driver
assumed that data buffers passed from SDDMC command layer would be
aligned. However alignment checks were never implemented in the command
layer, as were the checks that the buffer coming from the application
would be in DMA capable memory. Most of the time this was indeed true.
However in some cases FATFS library can pass buffers offset by 2 bytes
from word boundary. “DMA capable” restriction may be broken if pSRAM
support is used.

This change adds buffer checks to the SDMMC host driver (alignment and
DMA capability), so that the host layer will error out for incompatible
buffers. In SDMMC command layer, a check is added to read and write
functions. If an incompatible buffer is passed from the application, new
buffer (512 bytes size) is allocated, and the transfer is performed
using {READ,WRITE}_SINGLE_BLOCK commands.

fdfa7e6cc2 Merge branch 'bugfix/sdmmc_timeout' into 'master'
sdmmc: handle card removal when CD is not used

When SD card is removed during transaction, SDMMC peripheral can report
a range of errors, such as timeouts, CRC errors, start/end bit errors.
Under normal conditions (card is inserted), SDMMC peripheral also generates
command done or data done interrupts. When the card is removed, such
interrupts may not be always generated.

This change fixes handling of timeout interrupts and SBE interrupts.
It also adds a one second timeout into the event processing loop. This
timeout allows applications to recover in cases when the SDMMC peripheral
doesn’t generate command/data done event on card removal.

Fixes TW11592.

eeb0aaa09e spidriver: Display length errors correctly
SPI transfer length is bits, not bytes, so the error should indicate bits. Also, there are separate lengths for rx and
tx (confusingly named rxlength and length... if rxlength is 0, length is used). The code checks the tx length for the
rx, so it never validates rxlength.

94b91ee4af bugfix: i2c driver not working in 'RELEASE' configuration
This issue is reported from https://github.com/espressif/esp-idf/issues/304.
We found that when we operate the hw command registers in I2C struct, sometimes the behaviour would be different in DEBUG/RELEASE optimisation level:

The code looks like this:
I2C[i2c_num]->command[p_i2c->cmd_idx].byte_num -= 0;

In DEBUG configuration:
I2C[i2c_num]->command[p_i2c->cmd_idx].byte_num -= 0;
400f3ab0:    3388          l32i.n    a8, a3, 12
400f3ab2:    14c882            addi    a8, a8, 20
400f3ab5:    a08840            addx4    a8, a8, a4
400f3ab8:    0020c0            memw
400f3abb:    2898          l32i.n    a9, a8, 8
400f3abd:    0020c0            memw
400f3ac0:    28b8          l32i.n    a11, a8, 8
400f3ac2:    74a090            extui    a10, a9, 0, 8
400f3ac5:    00af92            movi    a9, 0xffffff00
400f3ac8:    109b90            and    a9, a11, a9
400f3acb:    2099a0            or    a9, a9, a10
400f3ace:    0020c0            memw
400f3ad1:    2899          s32i.n    a9, a8, 8

In RELEASE configuration:
I2C[i2c_num]->command[p_i2c->cmd_idx].byte_num -= 0;
400f2ba2:    580572            l8ui    a7, a5, 88
400f2ba5:    747070            extui    a7, a7, 0, 8
400f2ba8:    0020c0            memw
400f2bab:    584572            s8i    a7, a5, 88

Looks like the compiler will make it a 8bit operation after optimisation.
But the register value changes from 0x901 to 0x101.
After this 8-bit optimisation, the 11th bit changed from 1 to zero, which caused this error.

We are still trying to find out why that happens, because there might be some risk when operating the register struct.
This is a workaround to avoid "-=" operation on I2C register struct fields.
