Subject: [PATCH v6 RESEND 0/2] Tegra I2C DMA and SMBus blockread updates

The patchset contains two independent updates to tegra-i2c driver.
* Update I2C DMA channel usage to use single DMA channel instead of
two different hardware channels.
* Fix PEC byte issue during SMBus block read caused by mismanaged
msg->len property in i2c_msg struct.

v5->v6:
 Updated __u16 to unsigned int
v4->v5:
 Corrected the comment style
v3->v4:
 Combine the two patches to one series to avoid merge conflicts.

Akhil R (2):
  i2c: tegra: Fix PEC support for SMBUS block read
  i2c: tegra: Share same DMA channel for RX and TX
