From b51d33ea8a164bb5f0eec8ad817fa9730ac2b577 Mon Sep 17 00:00:00 2001 From: Til Kaiser Date: Mon, 13 Apr 2026 15:52:34 +0200 Subject: pinctrl: qcom: ipq4019: mark gpio as a GPIO pin function The qcom pinctrl core supports marking functions that represent GPIO mode via PINCTRL_GPIO_PINFUNCTION(), so that strict pinmuxing does not reject GPIO requests for pins that are muxed to the GPIO function. ipq4019 still describes its gpio function with QCA_PIN_FUNCTION(gpio), so it is not treated as a GPIO pin function. As a result, GPIO consumers can still conflict with pinctrl states that select the "gpio" function. Add a QCA_GPIO_PIN_FUNCTION() helper and use it for the ipq4019 gpio function, matching how the msm-based qcom drivers handle this. This allows ipq4019 to keep the GPIO-related pin configuration in DTS without tripping over strict pinmux ownership checks.
