Hi Sudeep, Linus Is it possible for you to pick up this patchset earlier if no major comments? Thanks, Peng. ARM SCMI v3.2 Table 24 Pin Configuration Type and Enumerations: '192 -255 OEM specific units'. i.MX95 System Manager FW supports SCMI PINCTRL protocol, but it has zero functions, groups. So pinctrl-scmi.c could not be reused for i.MX95. Because nxp,pin-func, nxp,pin-conf properties are rejected by dt maintainers, so use generic property 'pinmux' which requires a new driver pinctrl-imx-scmi.c The node will be as below: pinctrl_usdhc1: usdhc1-pins { sd1-grp0 { pinmux = <IMX95_PAD_SD1_CLK__USDHC1_CLK IMX95_PAD_SD1_STROBE__USDHC1_STROBE>; drive-strength = <0xe>; input-schmitt-enable; bias-pull-down; slew-rate = <0x3>; }; sd1-grp1 { pinmux = <IMX95_PAD_SD1_CMD__USDHC1_CMD IMX95_PAD_SD1_DATA0__USDHC1_DATA0 IMX95_PAD_SD1_DATA1__USDHC1_DATA1 IMX95_PAD_SD1_DATA2__USDHC1_DATA2 IMX95_PAD_SD1_DATA3__USDHC1_DATA3 IMX95_PAD_SD1_DATA4__USDHC1_DATA4 IMX95_PAD_SD1_DATA5__USDHC1_DATA5 IMX95_PAD_SD1_DATA6__USDHC1_DATA6 IMX95_PAD_SD1_DATA7__USDHC1_DATA7>; drive-strength = <0xe>; input-schmitt-enable; bias-pull-up; slew-rate = <0x3>; }; }; Signed-off-by: Peng Fan <peng.fan@xxxxxxx> --- Changes in v6: - Per Andy comment to v4, drop imx_pin_group wrapper; assign sdev->handle to handle first, then check handle. - Rebased to next-20240513 - Link to v5: https://lore.kernel.org/r/20240508-pinctrl-scmi-oem-v3-v5-0-6f2b167f71bc@xxxxxxx Changes in v5: - Added Rob'r R-b in patch 1 after addressed the comments - Per Rob, use of_machine_compatible_match for patch 2 - Use of_machine_compatible_match for patch 3, and enable COMPILE_TEST - Link to v4: https://lore.kernel.org/r/20240505-pinctrl-scmi-oem-v3-v4-0-7c99f989e9ba@xxxxxxx Changes in v4: - Rebase to next-20240503 - Add pinctrl-scmi-imx.c itself get pins and scmi pinctrl structure to decouple pinctrl-scmi.c and pinctrl-scmi-imx.c, so drop patch 3,4,5. - Link to v3: https://lore.kernel.org/r/20240428-pinctrl-scmi-oem-v3-v3-0-eda341eb47ed@xxxxxxx Changes in v3: - patch 2,3,4,5 are new. - Rewrite the binding, drop nxp,pin-x properties, use generic properties as Rob commented. - Switch to using pinmux means pinctrl-scmi.c could not be reused, so add a new driver in patch 6 for i.MX95. But pinctrl_scmi_get_pins and scmi_pinctrl are exported for i.MX95 usage. - Link to v2: https://lore.kernel.org/r/20240418-pinctrl-scmi-oem-v1-v2-0-3a555a3c58c3@xxxxxxx Changes in v2: - Rename nxp,imx95-pinctrl.yaml to nxp,imx95-scmi-pinctrl.yaml and move to firmware - Merged patch [1,2]/3 v1 into patch 1/2 v2. - nxp,imx95-scmi-pinctrl.yaml only has patterProperties for subnode The pinctrl will be as below for i.MX95. pinctrl_usdhc1: usdhc1-pins { sd1cmd { pins = "sd1cmd"; nxp,func-id = <0>; nxp,pin-conf = <0x138e>; }; sd1data { pins = "sd1data"; nxp,func-id = <0>; nxp,pin-conf = <0x138e>; }; }; - Add pins enum, correct description. - Link to v1: https://lore.kernel.org/r/20240412-pinctrl-scmi-oem-v1-v1-0-704f242544c1@xxxxxxx --- Peng Fan (3): dt-bindings: firmware: arm,scmi: Add properties for i.MX95 Pinctrl OEM extensions pinctrl: scmi: add blocklist pinctrl: imx: support SCMI pinctrl protocol for i.MX95 .../devicetree/bindings/firmware/arm,scmi.yaml | 9 +- .../bindings/firmware/nxp,imx95-scmi-pinctrl.yaml | 41 ++ drivers/pinctrl/freescale/Kconfig | 9 + drivers/pinctrl/freescale/Makefile | 1 + drivers/pinctrl/freescale/pinctrl-imx-scmi.c | 579 +++++++++++++++++++++ drivers/pinctrl/pinctrl-scmi.c | 9 + 6 files changed, 645 insertions(+), 3 deletions(-) --- base-commit: ca45a28e860e3ed34cff0ce5211014d535bf6d6d change-id: 20240428-pinctrl-scmi-oem-v3-12130031a74d Best regards, -- Peng Fan <peng.fan@xxxxxxx>
