drivers: create a pin control subsystem [LWN.net]

WebThe imx driver depend on the ability of the i.MX pin controller to use the pins as a certain function and GPIO at the same time. This is due to the imx pin controller not setting the .strict attribute on the struct pinmux_ops so that pins can be used in parallel for i2c and GPIO and gpiod_get() will not fail. WebTwo frameworks are available to configure and control a given pin: pinctrl and GPIOLib. They are selected according to pin usage: · pinctrl is used mainly when a pin is … clearance hole size for 3/8-16 bolt

WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. WebRework the driver to implement pinctrl and pinmux (despite the lack of actual mux hardware), and back the gpiochip and LED controller on to the resulting pin controller. This effort implements a custom devicetree device mapping callback for pinctrl to parse maps from the existing devicetree binding for the PCA955x devices. WebWith a DT/ACPI property to describe the set of pins that are available for use, parse the available pins and set the irq valid bits for gpiolib to know what to consider 'valid'. This should avoid any issues with gpiolib. Furthermore, implement the pinmux_ops::request function so that pinmux can also make sure to not use pins that are unavailable. clearance hole size for 4-40 screw
