2022-09-17dt-bindings: ata: ahci: Add Baikal-T1 AHCI SATA controller DT schemaSerge Semin1-0/+115
Baikal-T1 AHCI controller is based on the DWC AHCI SATA IP-core v4.10a with the next specific settings: two SATA ports, cascaded CSR access based on two clock domains (APB and AXI), selectable source of the reference clock (though stable work is currently available from the external source only), two reset lanes for the application and SATA ports domains. Other than that the device is fully compatible with the generic DWC AHCI SATA bindings.

2022-09-17dt-bindings: ata: ahci: Add DWC AHCI SATA controller DT schemaSerge Semin3-8/+177
Synopsys AHCI SATA controller is mainly compatible with the generic AHCI SATA controller except a few peculiarities and the platform environment requirements. In particular it can have at least two reference clocks to feed up its AHB/AXI interface and SATA PHYs domain and at least one reset control for the application clock domain. In addition to that the DMA interface of each port can be tuned up to work with the predefined maximum data chunk size. Note unlike generic AHCI controller DWC AHCI can't have more than 8 ports. All of that is reflected in the new DWC AHCI SATA device DT binding. Note the DWC AHCI SATA controller DT-schema has been created in a way so to be reused for the vendor-specific DT-schemas (see for example the "snps,dwc-ahci" compatible string binding). One of which we are about to introduce.

2022-09-17dt-bindings: ata: ahci: Add platform capability propertiesSerge Semin2-0/+26
In case if the platform doesn't have BIOS or a comprehensive firmware installed then the HBA capability flags will be left uninitialized. As a good alternative we suggest to define the DT-properties with the AHCI platform capabilities describing all the HW-init flags of the corresponding capability register. Luckily there aren't too many of them. SSS - Staggered Spin-up support and MPS - Mechanical Presence Switch support determine the corresponding feature availability for the whole HBA by means of the "hba-cap" property. Each port can have the "hba-port-cap" property initialized indicating that the port supports some of the next functionalities: HPCP - HotPlug capable port, MPSP - Mechanical Presence Switch attached to a port, CPD - Cold Plug detection, ESP - External SATA Port (eSATA), FBSCP - FIS-based switching capable port.

The Broadcom SATA controller is obviously based on the AHCI standard. The device driver uses the kernel AHCI library to work with it. Therefore we can be have a more thorough DT-bindings evaluation by referring to the AHCI-common schema instead of using the more relaxed SATA-common one.

2022-09-17dt-bindings: ata: sata: Extend number of SATA portsSerge Semin1-4/+3
The denoted in the description upper limit only concerns the Port Multipliers, but not the actual SATA ports. It's an external device attached to a SATA port in order to access more than one SATA-drive. So when it's attached to a SATA port it just extends the port capability while the number of actual SATA ports stays the same. For instance on AHCI controllers the number of actual ports is determined by the CAP.NP field and the PI (Ports Implemented) register. AFAICS in general the maximum number of SATA ports depends on the particular controller implementation. Generic AHCI controller can't have more than 32 ports (since CAP.NP is of 5 bits wide and PI register is 32-bits size), while DWC AHCI SATA controller can't be configured with more than 8 ports activated. So let's discard the SATA ports reg-property restrictions and just make sure that it consists of a single reg-item.

Indeed in accordance with what is implemented in the AHCI platform driver and the way the AHCI DT nodes are defined in the DT files we can add the next AHCI DT properties constraints: AHCI CSR ID is fixed to 'ahci', PHY name is fixed to 'sata-phy', AHCI controller can't have more than 32 ports by design, AHCI controller can have up to 32 IRQ lines.

2022-09-17dt-bindings: ata: ahci-platform: Detach common AHCI bindingsSerge Semin3-65/+115
In order to create a more sophisticated AHCI controller DT bindings let's divide the already available generic AHCI platform YAML schema into the platform part and a set of the common AHCI properties. The former part will be used to evaluate the AHCI DT nodes mainly compatible with the generic AHCI controller while the later schema will be used for more thorough AHCI DT nodes description. For instance such YAML schemas design will be useful for our DW AHCI SATA controller derivative with four clock sources, two reset lines, one system controller reference and specific max Rx/Tx DMA xfers size constraints. Note the phys and target-supply property requirement is preserved in the generic AHCI platform bindings because some platforms can lack of the explicitly specified PHYs or target device power regulators. Also note the SATA/AHCI ports properties have been moved to the $defs-paragraph of the schemas. It's done in order to create the extendable properties hierarchy such that particular AHCI-controller could add vendor-specific port properties.

2022-02-04dt-bindings: Improve phandle-array schemasRob Herring1-0/+3
The 'phandle-array' type is a bit ambiguous. It can be either just an array of phandles or an array of phandles plus args. Many schemas for phandle-array properties aren't clear in the schema which case applies though the description usually describes it. The array of phandles case boils down to needing: items: maxItems: 1 The phandle plus args cases should typically take this form: items: - items: - description: A phandle - description: 1st arg cell - description: 2nd arg cell With this change, some examples need updating so that the bracketing of property values matches the schema.

Note that is DT schema specific behavior and not standard json-schema behavior. The tooling will fixup the final schema adding any unspecified minItems/maxItems. This condition is partially checked with the meta-schema already, but only if both 'minItems' and 'maxItems' are equal to the 'items' length. An improved meta-schema is pending.

Unfortunately, there are a few cases where the size constraints are not defined such as common bindings, so the meta-schema can't be part of the normal checks.

2020-10-07dt-bindings: Explicitly allow additional properties in common schemasRob Herring2-0/+4
In order to add meta-schema checks for additional/unevaluatedProperties being present, all schema need to make this explicit. As common/shared schema are included by other schemas, they should always allow for additionalProperties.

2020-10-07dt-bindings: Add missing 'unevaluatedProperties'Rob Herring1-0/+2
This doesn't yet do anything in the tools, but make it explicit so we can check either 'unevaluatedProperties' or 'additionalProperties' is present in schemas. 'unevaluatedProperties' is appropriate when including another schema (via '$ref') and all possible properties and/or child nodes are not explicitly listed in the schema with the '$ref'. This is in preparation to add a meta-schema to check for missing 'unevaluatedProperties' or 'additionalProperties'. This has been a constant source of review issues.

2020-06-11dt-bindings: Remove more cases of 'allOf' containing a '$ref'Rob Herring1-12/+9
Another round of 'allOf' removals that came in this cycle. json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Signed-off-by: Rob Herring <robh@kernel.org>
