Hi,
From: Fabien DESSENNE fabien.dessenne@st.com Sent: vendredi 31 mai 2019 15:12
Add the following functions to translate DMA address to CPU address:
- dev_translate_dma_address()
- ofnode_translate_dma_address()
- of_translate_dma_address()
- fdt_translate_dma_address()
These functions work the same way as xxx_translate_address(), with the difference that the translation relies on the "dma-ranges" property instead of the "ranges" property.
Add related test. Test report: => ut dm fdt_translation Test: dm_test_fdt_translation: test-fdt.c Test: dm_test_fdt_translation: test-fdt.c (flat tree) Failures: 0
