Hi I am registering a device using platform_device_register_full(). In the above-mentioned api argument - 'struct platform_device_info', I set the parent device pointer, set_dma_mask from parent device etc.
The parent device is created by declaration in device tree and the relevant node has property 'dma-coherent'. So I get dma_coherent attribute as 1 for the parent device. In other words, is_dev_dma_coherent() returns 1 for parent device. But for the device registered using platform_device_register_full(), the dma_coherent is not set and is_dev_dma_coherent() returns 0. Can someone please guide me, how to declare the newly registered device as 'dma_coherent'. Regards Vakul
