Subject: [PATCH v5 0/4] Add STM32 MDMA driver
Date: Thu, 28 Sep 2017 17:36:39 +0200 [thread overview]
Message-ID: <1506613003-28376-1-git-send-email-pierre-yves.mordret@st.com> (raw)
This patchset adds support for the STM32 MDMA controller.
The Master Direct memory access (MDMA) provides high-speed data transfer
between memory and memory or between peripherals and memory.
Contrary to STM32 DMA, the STM32 MDMA controller supports hardware LLI and
uses a larger integrated FIFO (128 vs 16 bytes)
---
Version history:
v5:
* Change 'platform_driver_probe' into
'platform_driver_register' to manage defer mechanism
v4:
* Add safe getter/setter macros
* forbid DMA preparation in cyclic mode yet
* Optimize burst and memory width for memcpy
* replace of_property_xx by device_property_xx
v3:
* Update header template
* Unsigned expression compared with zero
* Rework stm32_mdma_get_max_width
* moved to src/dst case where they are used in set_xfer
* Change of_property_* with device_property_*
* Add dev_warn whether default value is used
* Indentation
* Add MODULE_*
v2:
* change compatible into st,stm32h7-mdma to be more SoC specific
* Add MDMA support in DT for H7
* Add MDMA support in STM32 defconfig
