as the driver needs it. Build error caught with a randconfig build:

  drivers/built-in.o: In function `mmp_tdma_prep_dma_cyclic':
  mmp_tdma.c:(.text+0x1612d9): undefined reference to `gen_pool_dma_alloc'
  drivers/built-in.o: In function `mmp_tdma_free_chan_resources':
  mmp_tdma.c:(.text+0x161444): undefined reference to `gen_pool_free'
  drivers/built-in.o: In function `mmp_tdma_probe':
  mmp_tdma.c:(.text+0x1616ac): undefined reference to `of_gen_pool_get'
  make: *** [vmlinux] Error 1
