Hello,

PLM_CTRL register has three kind of override fields.

What is the difference between VALID_OVERRIDE, HSYNC_OVERRIDE and VSYNC_OVERRIDE settings?

From IMX8DXAEC.pdf (Rev.0):

Hello Kazuma,

If valid_override is zero, this will override both HSYNC and VSYNC to be asserted.

If vsync_override is one, this will override VSYNC to be asserted.

If hsync_override is one, this will override HSYNC to be asserted.
