>> Other minor feedback
>> [V9] : Rebased to 5.0-rc4
>> Removed dependency of APB DMA in Kconfig and added conditional check
>> in I2C driver to decide on using DMA mode.
>> Changed back the allocation of dma buffer during i2c probe.
>> Fixed FIFO triggers depending on DMA Vs PIO.
>> [V8] : Moved back dma init to i2c probe, removed ALL_PACKETS_XFER_COMPLETE

>> Updated Kconfig for APB_DMA dependency
>> [V7] : Same as V6
>> [V6] : Updated for proper buffer allocation/freeing, channel release.
>> Updated to use exact xfer size for syncing dma buffer.
>> [V5] : Same as V4
>> [V4] : Updated to allocate DMA buffer only when DMA mode.
>> Updated to fall back to PIO mode when DMA channel request or
>> buffer allocation fails.
>> [V3] : Updated without additional buffer allocation.
>> [V2] : Updated based on V1 review feedback along with code cleanup for

BTW, I'm seeing "atmel_mxt_ts 0-004c: Warning: Info CRC error - device=0xF436DC file=0x000000" whithout making any modifications to the original patch as well and it shall not happen, hence there is bug somewhere. Probably FIFO triggers are still not set up correctly... ?
