Hi Simon, Thank you for this patch for rk3568 pcie. Include the Rockchip device tree maintainer and all other people/lists to the CC list. ./scripts/checkpatch.pl --strict <patch1> <patch2> ./scripts/get_maintainer.pl --noroles --norolestats --nogit-fallback --nogit <patch1> <patch2> git send-email --suppress-cc all --dry-run --annotate --to heiko@sntech.de --cc <..> <patch1> <patch2> This SoC has no support in mainline linux kernel yet. In all the following yaml documents for rk3568 we need headers with defines for clocks and power domains, etc. For example: #include <dt-bindings/clock/rk3568-cru.h> #include <dt-bindings/power/rk3568-power.h> Could Rockchip submit first clocks and power drivers entries and a basic rk3568.dtsi + evb dts? Include a patch to this serie with 3 pcie nodes added to rk3568.dtsi. A dtbs_check only works with a complete dtsi and evb dts. make ARCH=arm64 dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/pci/rockchip-dw-pcie.yaml On 1/18/21 10:17 AM, Simon Xue wrote: > Signed-off-by: Simon Xue <xxm@rock-chips.com> > --- > .../bindings/pci/rockchip-dw-pcie.yaml | 101 ++++++++++++++++++ > 1 file changed, 101 insertions(+) > create mode 100644 Documentation/devicetree/bindings/pci/rockchip-dw-pcie.yaml > > diff --git a/Documentation/devicetree/bindings/pci/rockchip-dw-pcie.yaml b/Documentation/devicetree/bindings/pci/rockchip-dw-pcie.yaml > new file mode 100644 > index 000000000000..fa664cfffb29 > --- /dev/null > +++ b/Documentation/devicetree/bindings/pci/rockchip-dw-pcie.yaml > @@ -0,0 +1,101 @@ > +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) > +%YAML 1.2 > +--- > +$id: http://devicetree.org/schemas/pci/rockchip-dw-pcie.yaml# > +$schema: http://devicetree.org/meta-schemas/core.yaml# > + > +title: DesignWare based PCIe RC controller on Rockchip SoCs > + > +maintainers: > + - Shawn Lin <shawn.lin@rock-chips.com> > + - Simon Xue <xxm@rock-chips.com> maintainers: - Heiko Stuebner <heiko@sntech.de> Add only people with maintainer rights. allOf: - $ref: /schemas/pci/pci-bus.yaml# designware-pcie.txt is in need for conversion to yaml.

I'd disagree on this ;-) The maintainer for individual drivers should be the persons who are actually know the hardware. We have individual Rockchip developers taking care of other drivers as well already. And normally scripts/get_maintainer.pl should already include me due to the wildcard for things having "rockchip" in the name. Heiko

This is a bizarrely circular argument - we can't have a binding without a DT to try validating against it? That's not how it usually works. We review and merge bindings first, then drivers that consume them and DTs that implement them. Examples within a binding itself do not need to represent a whole SoC, in fact that would usually just make them unnecessarily complicated. They do need to compile correctly in the `make dt_binding_check` environment, but if anything it makes more sense to strip down and simplify the example to fit that environment than to pile in enough other crap to realistically model all the supporting components from a particular SoC. Not least because the more extra stuff has to be crammed in, the more it distracts from the fundamental purpose of demonstrating *that specific binding* in use. For instance, a "clocks" property can quite happily use arbitrary numeric specifiers targeting a dummy clock controller node; requiring that some device binding depend on a particular clock controller binding being upstreamed just so that SoC-specific identifiers can then be used in an example would be rather absurd.

For the binding it's my call. :) This should be someone who cares and knows the h/w. IOW, if I want to delete the binding, someone who will object. Of course, I'd like that someone to have all the above qualities too. Rob

Shawn and Simon know the hardware way better, though I'm not sure if their work commitments will allow them to keep track of binding deletions So maybe all 3 of us ;-) Heiko

Yup, that's the point I was trying to clarify - binding maintainer and driver maintainer are technically distinct roles. Of course if someone is a driver maintainer then it's usual - and preferable - for them to maintain the relevant bindings as well, so MAINTAINERS entries for drivers typically also cover those for convenience and pre-schema historical reasons. However, someone can take responsibility for a binding without signing up to explicitly maintain a corresponding driver (I know I have), and in that case the schema makes the binding self-documenting already - we don't have MAINTAINERS entries that *only* cover bindings, other than the top-level one that says Rob's in charge overall :) Robin. > Shawn and Simon know the hardware way better, though I'm not sure if their > work commitments will allow them to keep track of binding deletions > > So maybe all 3 of us ;-) > > Heiko > >
