7 title: NXP QorIQ Layerscape LS1028A Display PIXEL Clock Binding
10 - Wen He <wen.he_1@nxp.com>
13 NXP LS1028A has a clock domain PXLCLK0 used for the Display output
14 interface in the display core, as implemented in TSMC CLN28HPM PLL.
15 which generate and offers pixel clocks to Display.
19 const: fsl,ls1028a-plldig
31 description: Optional for VCO frequency of the PLL in Hertz. The VCO frequency
32 of this PLL cannot be changed during runtime only at startup. Therefore,
33 the output frequencies are very limited and might not even closely match
34 the requested frequency. To work around this restriction the user may specify
35 its own desired VCO frequency for the PLL.
