michael	58955a79a2	spi_slave: improve the timing configuration ... SPI Slave =========== - Correct the configuration of mode 0~3 using new config in the TRM - Split the workaround for DMA in mode 0/2 out of normal config, to make it clear. - Update timing and speed document for the SPI slave. Resolves https://github.com/espressif/esp-idf/issues/1346, https://github.com/espressif/esp-idf/issues/2393	2019-01-26 00:10:41 +08:00
michael	cfba157fdd	spi_slave: add valid check for DMA buffers ... The DMA cannot receive data correctly when the buffer address is not WORD aligned. Currently we only check whether the buffer is in the DRAM region. The DMA always write in WORDs, so the length arguments should also be multiples of 32 bits. A check is added to see whether the buffer is WORD aligned and has valid length.	2018-11-26 03:49:26 +00:00
