Subject: [RESEND PATCH 0/3] Few Tegra210 ADMA fixes

Following are the fixes in the series:
 - Couple of minor fixes (non functional fixes)

 - ADMA FIFO size fix: The slave ADMAIF channels have different default
   FIFO sizes (ADMAIF FIFO is actually a ring buffer and it is divided
   amongst all available channels). As per HW recommendation the sizes
   should match with the corresponding ADMA channels to which ADMAIF
   channel is mapped to at runtime. Thus program ADMA channel FIFO sizes
   accordingly. Otherwise FIFO corruption is observed.

Sameer Pujar (3):
  dmaengine: tegra210-adma: Re-order 'has_outstanding_reqs' member
  dmaengine: tegra210-adma: Add description for 'adma_get_burst_config'
  dmaengine: tegra210-adma: Override ADMA FIFO size
