OSPI DQS and LBCLK nets swap

In AM263P the ball pins for OSPI DQS and LBCLK are as per below

  • OSPI0_DQS is from Ball pin M3
  • OSPI0_LBCLKO is from Ball pin L3

But as seen in the below image from LP-AM263P Schematics, the nets are wrongly swapped.

                        caution note in LP-AM263P Schematic Figure 4-1 OSPI DQS and LBCLK nets caution note in LP-AM263P Schematic

Hence to rectify this, as mentioned in the same schematic the resistor R381 is unmounted and the resistor R382 is mounted with 22Ω resistor. Also the resistor R375 is unmounted.

All boards ordered from ti.com already have this change made.
