The patchset contains driver and devicetree changes to support I2C and
PWM for Tegra234

v2->v1:
  * Reverted changes in i2c-tegra.c. using tegra194_i2c_hw for tegra234
    as the values are compatible.

Akhil R (4):
  dt-bindings: Add headers for Tegra234 I2C
  arm64: tegra: Add Tegra234 I2C devicetree nodes
  dt-bindings: Add headers for Tegra234 PWM
  arm64: tegra: Add Tegra234 PWM devicetree nodes

Do you mean RESET_UART4, SDMMC4 etc should be
below RESET_I2C*?

Yes, please see T186/194 headers for the example and do the same for
T234. Always try to use existing examples in general to maintain
consistency.
