From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andrew Jeffery Date: Wed, 28 Feb 2024 11:00:43 +1030 Subject: [PATCH v6] dt-bindings: gpio: aspeed,ast2400-gpio: Convert to DT schema Message-ID: <20240228003043.1167394-1-andrew@codeconstruct.com.au> List-Id: To: linux-aspeed@lists.ozlabs.org MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Squash warnings such as: ``` arch/arm/boot/dts/aspeed/aspeed-bmc-facebook-galaxy100.dtb: /ahb/apb at 1e600000/gpio at 1e780000: failed to match any schema with compatible: ['aspeed,ast2400-gpio'] ``` Signed-off-by: Andrew Jeffery --- v6: Address more constraint feedback from Krzysztof: https://lore.kernel.org/all/f69ef2ad-8ace-40c8-b923-4dde20eda2ec at linaro.org/ v5: https://lore.kernel.org/all/20240227052353.1060306-1-andrew at codeconstruct.com.au/ Resolve macro definition clashes from aspeed clock headers in examples identified by Rob's bot: https://lore.kernel.org/all/170900020204.2360855.790404478830111761.robh at kernel.org/ Clearly I missed running `make dt_binding_check` on the final iteration of the v4 patch I sent. Hopefully I'm running out of rakes to step on here! v4: https://lore.kernel.org/all/20240227004414.841391-1-andrew at codeconstruct.com.au/ Add constraints for gpio-line-names, ngpios as requested by Krzysztof: https://lore.kernel.org/all/458becdb-fb1e-4808-87b6-3037ec945647 at linaro.org/ Add more examples to exercise constraints. v3: https://lore.kernel.org/all/20240226051645.414935-1-andrew at codeconstruct.com.au/ Base on v6.8-rc6, fix yamllint warning Rob's bot picked the missing `#interrupt-cells` in the example on v2[1]. The patch was based on v6.8-rc1, and going back over my shell history I missed the following output from `make dt_binding_check`: ``` ... LINT Documentation/devicetree/bindings usage: yamllint [-h] [-] [-c CONFIG_FILE | -d CONFIG_DATA] [--list-files] [-f {parsable,standard,colored,github,auto}] [-s] [--no-warnings] [-v] [FILE_OR_DIR ...] yamllint: error: one of the arguments FILE_OR_DIR - is required ... ``` I've rebased on v6.8-rc6 and no-longer see the issue with the invocation of `yamllint`.
