Later on many compatible were added in driver. But not update back to binding doc. <Documentation/devicetree/bindings/gpio/8xxx_gpio.txt> --- followed by "fsl,mpc8349-gpio" for 83xx, "fsl,mpc8572-gpio" for 85xx and "fsl,mpc8610-gpio" for 86xx. --- <drivers/gpio/gpio-mpc8xxx.c> --- static struct of_device_id mpc8xxx_gpio_ids[] __initdata = { { .compatible = "fsl,mpc8349-gpio", }, { .compatible = "fsl,mpc8572-gpio", }, { .compatible = "fsl,mpc8610-gpio", }, { .compatible = "fsl,mpc5121-gpio", .data = mpc512x_irq_set_type, }, { .compatible = "fsl,pq3-gpio", }, { .compatible = "fsl,qoriq-gpio", }, {} }; --- Grant/Rob, With respect peters explanation (below), what is your opinion on adding information to binding doc for da850 support? Peter --> if the hardware block is identical the dts should simply list: Peter --> compatible = "ti,da850-ecap", "ti,am33xx-ecap" Peter --> And the driver only bind to ti,am33xx-ecap (unless there ever needs to Peter --> be a da850 specific workaround. Or Should I update both binding doc & the driver to use new compatible option "ti,da830-ecap" (as da830 platform has initial IP support)? Even with this, platforms da830, da850 and am33xx can reuse "ti,da830-ecap" compatible field.
