imx8mp eARC not used strapping recommendations

Hi,

In the imx8mp datahseet there are recommendations about unused function. I will not use eARC function, so recommendations says:

  • VDD_EARC_1P8 tied to  ground  using a 10k resistor.
  • EARC_AUX, EARC_N_HDP, EARC_P_UTIL can be not connected

But, it is easier for my layout to leave this ball connected to 1v8 than connect to an 10k resistor to GND.

Is there a problem if VDD_EARC_1P8 is 1v8 powered and EARC_AUX, EARC_N_HDP, EARC_P_UTIL is not connected?Captura.PNG
