Subject: [PATCH V2 0/2] spi: stm32-qspi: add dma support

From: Ludovic Barre <ludovic.barre@...com>

This patch series adds dma support for the stm32-qspi.
In read mode, the memory map is preferred vs dma
(due to better throughput). If the dma transfer fails the buffer is
sent by polling.

V2:
-fixe build error in patch 1/2 (move qspi->phys_base in patch 2)

Ludovic Barre (2):
  spi: stm32-qspi: add spi_master_put in release function
  spi: stm32-qspi: add dma support
