I'd agree with Alex ... ideally the devicetree should match the block register area from the TRM not some internal offset. [DT describes hardware etc etc ;-) ] Heiko

The RK3288 TRM documents a so-called "VPU combo", and then documents the encoder and the decoder cores as separate engines, with separate register blocks (called VEPU and VDPU). In fact, for each register block you'll see swreg0 documented at offset 0x0. (In some integrations they can operate independently, but iirc not in RK3288.) So to be clear, instead of: vpu: video-codec@ff9a0000 { compatible = "rockchip,rk3288-vpu"; reg = <0x0 0xff9a0000 0x0 0x800>; interrupts = <GIC_SPI 9 IRQ_TYPE_LEVEL_HIGH>, <GIC_SPI 10 IRQ_TYPE_LEVEL_HIGH>; interrupt-names = "vepu", "vdpu"; clocks = <&cru ACLK_VCODEC>, <&cru HCLK_VCODEC>; clock-names = "aclk", "hclk"; ... It could have looked like: vpu: video-codec@ff9a0000 { compatible = "rockchip,rk3288-vpu"; reg = <0x0 0xff9a0000 0x0 0x400> <0x0 0xff9a0400 0x0 0x400>; ... I guess I missed this when RK3328 was pushed, but OTOH I don't see any real impact in doing things this way. So at the end of the day, I'm fine either way. BTW, the series is not adding the vpu node for arch/arm/boot/dts/rk3036.dtsi right? Thanks a lot! Ezequiel

In fact, for each > register block you'll see swreg0 documented at offset 0x0. I've always looked at the "Address Mapping" section in the TRMs when I checked the register offsets. I can't find a seperation the vpu block there (for any SoC). I've found it more unfortunate, that they started with register offset 0x0 for vdpu and vepu, since none of the SoCs (so far) can use the blocks separately. > (In some integrations they can operate independently, but iirc not in RK3288.) > > So to be clear, instead of: > > vpu: video-codec@ff9a0000 { > compatible = "rockchip,rk3288-vpu"; > reg = <0x0 0xff9a0000 0x0 0x800>; > interrupts = <GIC_SPI 9 IRQ_TYPE_LEVEL_HIGH>, > <GIC_SPI 10 IRQ_TYPE_LEVEL_HIGH>; > interrupt-names = "vepu", "vdpu"; > clocks = <&cru ACLK_VCODEC>, <&cru HCLK_VCODEC>; > clock-names = "aclk", "hclk"; > ... > > It could have looked like: > > vpu: video-codec@ff9a0000 { > compatible = "rockchip,rk3288-vpu"; > reg = <0x0 0xff9a0000 0x0 0x400> > <0x0 0xff9a0400 0x0 0x400>; > ... > > I guess I missed this when RK3328 was pushed, but OTOH I don't > see any real impact in doing things this way.

Ups, yes - I missed to submit this patch with v1 - I added it in its original version to v2 (so we know, what we are talking about)- If you think it should be changed, please reply to v2. > Thanks a lot! > Ezequiel > Thanks, Alex
