This series fixes a race condition observed when using several ADCs with DMA and irq. There's a precusor patch to the fix. It keeps registers definitions as a whole block, to ease readability and allow simple (readl) access path to EOC bits in stm32-adc-core driver. --- Changes in v2: - Add a precursor patch to follow Jonathan's comment on readability Fabrice Gasnier (2): iio: adc: stm32-adc: move registers definitions iio: adc: stm32-adc: fix a race when using several adcs with dma and irq drivers/iio/adc/stm32-adc-core.c | 70 +++++++++++--------- drivers/iio/adc/stm32-adc-core.h | 137 +++++++++++++++++++++++++++++++++++++++ drivers/iio/adc/stm32-adc.c | 109 ------------------------------- 3 files changed, 177 insertions(+), 139 deletions(-)
