Subject: RE: [PATCH V16 4/6] i2c: tegra: Add DMA support


> I'm still also suggesting to squash "fix maximum transfer size" into this patch because it is really part of DMA-support enabling.

Max transfer length limits apply to PIO also but for DMA its more needed to prevent crash.
So had this as patch before DMA as its applicable for both DMA & PIO.
We exchanged on this yesterday, so thought the reason you want to squash separate patch and include in this is due to max msg len limit and when moved into hw feature
