build testing on x86 revealed a missing dependency that leads to a link error:
drivers/dma/built-in.o: In function `mmp_tdma_prep_dma_cyclic': mmp_tdma.c:(.text+0x9564): undefined reference to `gen_pool_dma_alloc' drivers/dma/built-in.o: In function `mmp_tdma_free_chan_resources': mmp_tdma.c:(.text+0x9675): undefined reference to `gen_pool_free' drivers/dma/built-in.o: In function `mmp_tdma_probe': mmp_tdma.c:(.text+0x9854): undefined reference to `of_gen_pool_get' This adds a 'select' statement to the driver to get it to build cleanly.
