Rely on irq_map support, move more dma shared code between mt7921 and mt7925 in mt792x_dma.c Move the following dma code in mt792x-lib - mt792x_dma_enable - mt792x_dma_reset - mt792x_wpdma_reset - mt792x_wpdma_reinit_cond Signed-off-by: Lorenzo Bianconi <[email protected]> Signed-off-by: Deren Wu <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>
