1. provide options for bluetooth low power mode
2. provide two options for bluetooth low power clock: main XTAL and external 32kHz XTAL
3. provide function and callbacks to control bluetooth low power mode, including enable/disable sleep, software wakeup request, low power clock settings, check power state, etc
4. modify vhci API vhci_host_send_packet to use blocking mode
5. note that DFS and bluetooth modem sleep can not be used together currently.
1. Fix the duty fade check issue reported from https://github.com/espressif/esp-idf/issues/1914
2. Fix the duty overflow issue when duty_scale is set to 1.
3. Fix the duty fade error when a fade operation is under way. We must configure a new duty setting after the previous fade operation has finished due to hardware limit.
4. Add thread-safe version APIs to set duty and fade.
5. Correct the duty range in driver.
- 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)
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().
Merges https://github.com/espressif/esp-idf/pull/1740
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.
requirement from github(https://github.com/espressif/esp-idf/issues/805): to provide the position in the buffer of the pattern detected.
requirement from AT application: in AT app, when no hardware flow control is enabled, in some situation the rx buffer might be full, and the terminator “+++” might be lost, we can use pattern detect interrupt to avoid missing the terminator. When pattern detect interrupt happens, it will not send a data event at the same time.
1. Add API to get position of detected pattern in rx buffer
2. Modify UART event example
3. Add comments for uart_flush, add alias API uart_flush_input to clear the rx buffer
4. Modify the way rx_buffered_len is calculated
1. move settings of WIFI_CLK_EN_REG for bluetooth into controller init/deinit APIs
2. modify the bit mask used in phy_rf init/deinit to use WIFI-BT shared bits
append adc support and api
- esp_err_t adc2_config_width(adc_bits_width_t width_bit);
- esp_err_t adc2_config_channel_atten(adc2_channel_t channel, adc_atten_t atten);
- int adc2_get_voltage(adc2_channel_t channel);

In uart driver we didn't change the default value of tx idle num, so there would be a delay after tx FIFO is empty.
1. Add API to set tx idle interval before next data transmission. (The UART hardware can add an interval after tx FIFO is empty).
2. Set default tx idle interval to zero.
3. Add hardware disable in uart driver delete function.
