morris 9d97e439c8 fix(sdspi): reject oversized pre-read data before block receive 
Guard start_command_read_blocks against cards that place TOKEN_BLOCK_START so early that extra_data_size exceeds the bytes expected on the current iteration. Without this check, the unsigned subtraction for will_receive underflows and propagates into memset, SPI transaction length, and memcpy counts against the fixed 516-byte block buffer.

morris 0b2cf7f2ea fix(i2c): release platform mutex on intr/pm_lock delete failure 
ESP_RETURN_ON_ERROR inside the s_i2c_platform.mutex critical section
returns without releasing the mutex, permanently blocking all I2C
bus operations. Replace with ESP_GOTO_ON_ERROR that jumps to a
cleanup label releasing the mutex before return.

morrisandCursor 650cfd2b01 fix(sdio_slave): align buffer size checks with descriptor limits 
Define per-target SDIO slave descriptor buffer limits in the LL layer and validate queued send buffers against the 4-byte aligned effective maximum. Update the public docs to describe the chip-dependent limit instead of hardcoding 4092 bytes.

Song Ruo Jing 0428bd18bf fix(uart): lp uart rx iomux pin was not working as expected 
Introduced in 8818157e42
The workaround in the commit routes the signal to LP GPIO matrix first.
When uses LP IOMUX pin as UART RX, the signal did not bypass the matrix,
which caused the issue.

This commit adds rtc_gpio_iomux_input and rtc_gpio_iomux_output APIs
to align with existing GPIO driver APIs.

Song Ruo Jing 8c9f364f3a fix(uart): Avoid division by zero error when calling uart_get_baudrate 
If uart_driver_install is not called before uart_get_baudrate,
the UART port may not be ready. In such cases, the register values
cannot be read out, leading to a division by zero error in uart_ll_get_baudrate.
This commit adds a check to ensure the UART port is enabled before
attempting to read its registers.
