DRDY polarity

[wushengyong]

The TFT uses DRDY signal, no HSYNC and VSYNC. The polarity of DRDY of TFT requires high active, but in iMX DS, it is active low, could the polarity to be set to high? the same question for CLK.

Hello,

  It is possible change the polarity of the IPU output. Please refer to IPUx_DI0_POL register

description in I.MX6 RM. Note, for i.MX6, signal IPUx_DIx_PIN15 is used DRDY/DV (Data
validation/blank, data enable).

Have a great day,
Yuri
