Did you actually code this up and try it and get this error? I hadn't
tried it but I researched other dts files and it looked as if there
was one example that was doing this. ...but perhaps it wasn't
actually doing the ioremap_resource on both ranges.
I'd imagine that this is _probably_ equivalent to what Thierry was
suggesting, so if it didn't work then maybe Thierry's won't work
either?
I don't have any other great suggestions other than doing two memory
ranges for lcdc:
lcdc@ff930000 {
compatible = "rockchip,rk3288-lcdc";
reg = <0xff930000 0x1a0>, <0xff9301b0 0xfe50>;
...
};
pwm@ff9301a0 {
compatible = "rockchip,vop-pwm";
reg = <0xff9301a0 0x10>;
...
};
...but I am certainly nowhere near an expert on this stuff...
