When using DPort to read fifo, fifo_cnt is not credible, we need to calculate the real cnt based on the fifo read and write pointer. When using AHB to read FIFO, we can use fifo_cnt to indicate the data length in fifo.
On ESP32, due to fifo reset issue, UART2 will work incorrectly if reset the fifo of UART1(TX fifo and RX fifo). The software can workaround the RX fifo reset issue,
while the TX fifo reset issue can not. When UART2 is used and UART1 is used as the log output port, a software reset can reproduce this issue. So we should reset the UART memory
before the software reset to solve this problem.
Bugfix(I2S): Fix i2s_comm_format_t configuration parameter does not match the TRM bug
Closes IDFGH-3040, IDFGH-2913, IDFGH-578, IDFGH-2408, and IDFGH-3117
See merge request espressif/esp-idf!8339
- for ESP32 only enabled in case of unicore config
- capability wise this region (8K) is same as DRAM, except non-DMA capable
- also fixed small issue in reserved memory region processing when (start == end)
* Keep only USB related register operations in the LL.
* Move pad-related logic into the driver.
* Driver is now responsible for enabling the peripheral.

This commit updates the watchdog timers (MWDT and RWDT)
in the following ways:
- Add seprate LL for MWDT and RWDT.
- Add a combined WDT HAL for all Watchdog Timers
- Update int_wdt.c and task_wdt.c to use WDT HAL
- Remove most dependencies on LL or direct register access
in other components. They will now use the WDT HAL
- Update use of watchdogs (including RTC WDT) in bootloader and
startup code to use the HAL layer.
* Add test support for ESP32S2
* Add loop back test
* Support chip internal connection, no external wiring required.
* Delete the relevant codes of PDM of ESP32-S2 ll layer.
* fix dac dma mode issue
Prefer assertions, making available functions only when caps support it
for cpu-related abstractions.
Changes cpu hal functions to stall, unstall, reset to not accept -1;
instead prefering macros that provide the same functionality.
Configurable option to use IRAM as byte accessible memory (in single core mode) using
load-store (non-word aligned and non-word size IRAM access specific) exception handlers.
This allows to use IRAM for use-cases where certain performance penalty
(upto 170 cpu cycles per load or store operation) is acceptable. Additional configuration
option has been provided to redirect mbedTLS specific in-out content length buffers to
IRAM (in single core mode), allows to save 20KB per TLS connection.
On the ESP32S2, rtc_clk_cal(RTC_CAL_RTC_MUX) measures the frequency
of the 90kHz RTC clock regardless of the selected slow clock
frequency. Keep track which clock is selected and pass the argument
to rtc_clk_cal accordingly.
fix clock choices
update rtc 32k xtal code for s2
missed api in rtc.h
bootloader_clock: update for S2
These definitions have ended up being chip specific. Moving them into
respective soc_memory_layout.c makes the whole picture of memory
regions easier to see, and also makes adding support for new chips
easier.
spin_lock: cleaned-up port files and removed portmux files
components/soc: decoupled compare and set operations from FreeRTOS
soc/spinlock: filled initial implementation of spinlock refactor
It will decouple the spinlocks into separated components with not depencences of freertos
an similar interface was provided focusing the readabillity and maintenance, also
naming to spinlocks were adopted. On FreeRTOS side the legacy portMUX macros
gained a form of wrapper functions that calls the spinlocks component thus
minimizing the impact on RTOS side.
This feature aims to close IDF-967
soc/spinlock: spinlocks passed on unit test, missing test corner cases
components/compare_set: added better function namings plus minor performance optimization on spinlocks
soc/spinlock: code reordering to remove ISC C90 mix error
freertos/portmacro: gor rid of critical sections multiline macros, placed inline functions instead
soc/spinlock: improved spinlock performance from internal RAM
For cases where the spinlock is executed from IRAM, there is no
need to check where the spinlock object is placed on memory,
removing this checks caused a great improvement on performance.
The following commit refactors the CAN driver such that
it is split into HAL and Lowlevel layers. The following
changes have also been made:
- Added bit field members to can_message_t as alternative
to message flags. Updated examples and docs accordingly
- Register field names and fields of can_dev_t updated
