Missing implementation of HAL SPI master automatic SUSP in receive mode

[savinz]

Hi,

STM32H7xx_HAL_Driver defines the MasterReceiverAutoSusp configuration option in SPI Configuration Structure definition (SPI_InitTypeDef):

uint32_t MasterReceiverAutoSusp;

And the associated modes:

SPI_MASTER_RX_AUTOSUSP_DISABLE
SPI_MASTER_RX_AUTOSUSP_ENABLE

But the implementation is missing. Even if the SPI is configured with:

...
phspi->Init.MasterReceiverAutoSusp = SPI_MASTER_RX_AUTOSUSP_ENABLE;
HAL_SPI_Init(phspi);

RxFIFO can still overrun because MASRX bit is not set accordingly in hspi->Instance->CR1 by the HAL SPI driver.

Best regards, Savin
