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