MIPS: ingenic: JZ4725B: Add IPU node (d8727385) · Commits · 戴 / test

Add a devicetree node for the Image Processing Unit (IPU) found in the JZ4725B. Connect it with graph nodes to the LCD node. The LCD driver will expect the IPU node to be accessed through graph port #8, as stated in the bindings documentation. Signed-off-by:
