[PATCH 0/5] Add support for STM32F4 SPI

From: Cezary Gapinski This series of patches adds support for first generation of SPI interface for STM32F4 family. This version of driver is mostly different to STM32H7 one. Based on linux kernel I2C drivers for STM32 where drivers were splited into STM32F4 and STM32F7 family the same approach

[PATCH 3/5] spi: stm32: add driver for STM32F4 controller

From: Cezary Gapinski The STM32F4 Serial Peripheral Interface (SPI) can be used to communicate with external devices while using the specific synchronous protocol. This version supports full-duplex communication with 8 or 16-bit per word. DMA capability is optionally supported when RX and TX

[PATCH v2 03/14] spi: stm32: fix DMA configuration with only one channel

From: Cezary Gapinski When SPI driver is configured to work only with TX or RX DMA channel then dmaengine functions can dereferene NULL pointer. Running full-duplex mode when when only RX or TX DMA channel is available can cause overrun condition or incorrect writing to transmit buffer so
