2023-02-28gpio: gpio-rockchip: parse gpio-ranges for bank idChris Morgan
Use the new devicetree property of gpio-ranges to determine the GPIO bank ID. Preserve the "old" way of doing things too, so that boards can be migrated and tested gradually (I only have a 3566 and 3326 to test).

2022-10-29gpio-uclass: fix gpio lookup by labelRasmus Villemoes
Matching anything that just happens to have the sought-for label as a prefix is wrong. For example, if the board designer has designated 10 lines for debug purposes, named "debug1" through "debug10", and we are looking up "debug1", if debug10 happens to be met first during the iteration we'd wrongly return that. In theory, this can break existing users that could rely on this quirk, but OTOH keeping the current broken semantics can cause a lot of grief for people hitting this in the future and not understanding why they don't find the line they expect. Considering how few in-tree defconfigs currently set DM_GPIO_LOOKUP_LABEL (ignoring sandbox, only four "real" boards), let's fix it before the use becomes more widespread.

2022-09-19pinctrl: at91-pio4: Bind GPIO driver to the pinctrl DT nodeSergiu Moga
This has been done in order to align the DT of U-Boot with the DT of Linux. In Linux, a phandle from a '-gpio' DT property is linked to the pinctrl driver, a single driver that handles both pinctrl settings and offers GPIO API to callers. On the other hand, U-Boot redirects such phandle to a corresponding UCLASS_GPIO driver, because U-Boot offers two different types of drivers in this case: UCLASS_PINCTRL which handles pin functions and UCLASS_GPIO which handles gpio requests as a gpio provider. Due to this, we have two drivers in Uboot, but the Devicetree has a single node. Thus, just one of the drivers can be probed for the DT node during platform initialization, before relocation. Our previous solution in U-Boot was to have a different devicetree: the gpio node has a subnode for the pinctrl driver, which is not compliant with Linux ABI. Furthermore, our documentation for this type of nodes mentions no such gpio compatible. After this patch, we can no longer add nodes with a gpio compatible in the DT. Thus, in order to link the pinctrl driver to the gpio one, a hook to the bind method of the former in U-Boot has been added and the GPIO related compatibles have been removed to avoid conflict when compatibles are enumerated and bound to drivers during platform start before relocation. The bind method will attach the GPIO driver to the pinctrl DT node so that every phandle coming from '-gpio' DT properties will be redirected to a valid driver attached to the pinctrl DT node.

2022-08-26arm: dts: qcom: Sync pinctrl DT nodes with Linux bindingsSumit Garg
Currently for all Qcom SoCs/boards there are separate compatibles for GPIO and pinctrl. But this is inconsistent with official (upstream) Linux bindings which requires only a single compatible "qcom,<SoC name>-pinctrl" and there is no such compatible property as "qcom,tlmm-<SoC name>". So fix this inconsistency for Qcom SoCs in order to comply with upstream DT bindings. This is done via removing compatibles from "msm_gpio" driver and via binding to "msm_gpio" driver from pinctrl driver in case "gpio-controller" property is specified for pinctrl node.
