Each of these subnodes represents some desired configuration for a ++pin, a group, or a list of pins or groups. This configuration can include the ++mux function to select on those pin(s)/group(s), and various pin configuration ++parameters, such as pull-up, drive strength, etc. ++ ++The name of each subnode is not important; all subnodes should be enumerated ++and processed purely based on their content. ++ ++Each subnode only affects those parameters that are explicitly listed. In ++other words, a subnode that lists a mux function but no pin configuration ++parameters implies no information about any pin configuration parameters. ++Similarly, a pin subnode that describes a pullup parameter implies no ++information about e.g. the mux function. ++ ++ ++The following generic properties as defined in pinctrl-bindings.txt are valid ++to specify in a pin configuration subnode: ++ ++ pins, function, bias-disable, bias-pull-down, bias-pull,up, drive-strength, ++ output-low, output-high. ++ ++Non-empty subnodes must specify the 'pins' property. ++ ++Valid values for qcom,pins are: ++ gpio0-gpio68 ++ Supports mux, bias, and drive-strength ++ ++ sdc3_clk, sdc3_cmd, sdc3_data ++ Supports bias and drive-strength ++ ++ ++Valid values for function are: ++ mdio, mi2s, pdm, ssbi, spmi, audio_pcm, gsbi1, gsbi2, gsbi4, gsbi5, ++ gsbi5_spi_cs1, gsbi5_spi_cs2, gsbi5_spi_cs3, gsbi6, gsbi7, nss_spi, sdc1, ++ spdif, nand, tsif1, tsif2, usb_fs_n, usb_fs, usb2_hsic, rgmii2, sata, ++ pcie1_rst, pcie1_prsnt, pcie1_pwren_n, pcie1_pwren, pcie1_pwrflt, ++ pcie1_clk_req, pcie2_rst, pcie2_prsnt, pcie2_pwren_n, pcie2_pwren, ++ pcie2_pwrflt, pcie2_clk_req, pcie3_rst, pcie3_prsnt, pcie3_pwren_n, ++ pcie3_pwren, pcie3_pwrflt, pcie3_clk_req, ps_hold ++ ++Example: ++ ++ pinmux: pinctrl@800000 { ++ compatible = "qcom,ipq8064-pinctrl"; ++ reg = <0x800000 0x4000>; ++ ++ gpio-controller; ++ #gpio-cells = <2>; ++ interrupt-controller; ++ #interrupt-cells = <2>; ++ interrupts = <0 32 0x4>; ++ ++ pinctrl-names = "default"; ++ pinctrl-0 = <&gsbi5_uart_default>; ++ ++ gsbi5_uart_default: gsbi5_uart_default { ++ mux { ++ pins = "gpio18", "gpio19"; ++ function = "gsbi5"; ++ }; ++ ++ tx { ++ pins = "gpio18"; ++ drive-strength = <4>; ++ bias-disable; ++ }; ++ ++ rx { ++ pins = "gpio19"; ++ drive-strength = <2>; ++ bias-pull-up; ++ }; ++ }; ++ }; +-- +1.7.10.4 + |
