-
-Driver capability:
-
-- The driver supports the STM32 traditional DMA controller in the following
- configurations: 5ch, 7ch, 7ch+5ch, 7ch+7ch.
-- Support for automatic the channel selection through the CSELR register.
-- For devices without CSELR register it is possible to select channels but
- the SYSCFG CFGR register is not configured, the user has to configure it
- before starting the DMA driver.
-- The driver supports shared ISR handlers with a quirk: the IRQ priority is
- established by the first allocated channel among the channels sharing the
- ISR.
-
-The file registry must export:
-
-STM32_ADVANCED_DMA - TRUE not used by the DMA drivers but other
- drivers use it to enable checks on DMA
- channels. Probably will be removed in the
- future.
-STM32_DMA_SUPPORTS_CSELR - TRUE if the DMA have a CSELR register.
-STM32_DMA_SUPPORTS_DMAMUX - TRUE if the DMA is riven by a DMAMUX.
-STM32_DMAn_NUM_CHANNELS - Number of channels in DMAs "n" (1..2).
-STM32_DMAn_CHx_HANDLER - Vector name for IRQ "x" (1..7). If the macro
- is not exported then the ISR is not declared.
-STM32_DMAn_CHx_NUMBER - Vector number for IRQ "x" (1..7).
