In cases where the client bus gets corrupted or if the end device ceases to send/receive data, the DMA could wait for the data forever. Tegra234 supports recovery of such channels hung in flush mode.
Add a separate compatible for Tegra234 so that this scenario can be handled in the driver.
v3->v4: * Updated binding doc to use enum for compatible instead of const v2->v3: * Updated binding docs and device tree compatible v1->v2: * split device tree change to a different patch. * Update commit message
