The driver handles these as optional and uses MTK_CQDMA_NR_VCHANS and

Does this mean that you have to resources at base = 0x0 with different length?

Does this mean that you have to resources at base = 0x0 with different length?
For the next time, please send driver and binding description in one series (two
