Add device tree bindings for IPQ5332 TLMM block. Signed-off-by: Kathiravan T <quic_kathirav@xxxxxxxxxxx> --- Changes in V3: - Grouped the individual pin entries of pta[0-2] and xfem[0-7] to pta and xfem - Used the descriptive function names for wci pins to avoid the ambiguity - Din't pick up the Reviewed-By tag due to the above changes Changes in V2: - Renamed the file name to match with compatible - Added 'maxItems' for 'interrupt' property - Fixed the gpio pattern to 0 to 52 GPIOs instead of 0 to 53 GPIOs - Converted the function names to lowercase and sort it .../bindings/pinctrl/qcom,ipq5332-tlmm.yaml | 134 ++++++++++++++++++ 1 file changed, 134 insertions(+) create mode 100644 Documentation/devicetree/bindings/pinctrl/qcom,ipq5332-tlmm.yaml diff --git a/Documentation/devicetree/bindings/pinctrl/qcom,ipq5332-tlmm.yaml b/Documentation/devicetree/bindings/pinctrl/qcom,ipq5332-tlmm.yaml new file mode 100644 index 000000000000..300747252a7b --- /dev/null +++ b/Documentation/devicetree/bindings/pinctrl/qcom,ipq5332-tlmm.yaml @@ -0,0 +1,134 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/pinctrl/qcom,ipq5332-tlmm.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Qualcomm IPQ5332 TLMM pin controller + +maintainers: + - Bjorn Andersson <andersson@xxxxxxxxxx> + - Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> + +description: | + Top Level Mode Multiplexer pin controller in Qualcomm IPQ5332 SoC. + +allOf: + - $ref: /schemas/pinctrl/qcom,tlmm-common.yaml# + +properties: + compatible: + const: qcom,ipq5332-tlmm + + reg: + maxItems: 1 + + interrupts: + maxItems: 1 + + interrupt-controller: true + "#interrupt-cells": true + gpio-controller: true + "#gpio-cells": true + gpio-ranges: true + wakeup-parent: true + + gpio-reserved-ranges: + minItems: 1 + maxItems: 27 + + gpio-line-names: + maxItems: 53 + +patternProperties: + "-state$": + oneOf: + - $ref: "#/$defs/qcom-ipq5332-tlmm-state" + - patternProperties: + "-pins$": + $ref: "#/$defs/qcom-ipq5332-tlmm-state" + additionalProperties: false + +$defs: + qcom-ipq5332-tlmm-state: + type: object + description: + Pinctrl node's client devices use subnodes for desired pin configuration. + Client device subnodes use below standard properties. + $ref: qcom,tlmm-common.yaml#/$defs/qcom-tlmm-state + + properties: + pins: + description: + List of gpio pins affected by the properties specified in this + subnode. + items: + pattern: "^gpio([0-9]|[1-4][0-9]|5[0-2])$" + minItems: 1 + maxItems: 36 + + function: + description: + Specify the alternative function to be configured for the specified + pins. + + enum: [ atest_char, atest_char0, atest_char1, atest_char2, atest_char3, + atest_tic, audio_pri, audio_pri0, audio_pri1, audio_sec, + audio_sec0, audio_sec1, blsp0_i2c, blsp0_spi, blsp0_uart0, + blsp0_uart1, blsp1_i2c0, blsp1_i2c1, blsp1_spi0, blsp1_spi1, + blsp1_uart0, blsp1_uart1, blsp1_uart2, blsp2_i2c0, blsp2_i2c1, + blsp2_spi, blsp2_spi0, blsp2_spi1, core_voltage, cri_trng0, + cri_trng1, cri_trng2, cri_trng3, cxc_clk, cxc_data, dbg_out, + gcc_plltest, gcc_tlmm, gpio, lock_det, mac0, mac1, mdc0, mdc1, + mdio0, mdio1, pc, pcie0_clk, pcie0_wake, pcie1_clk, pcie1_wake, + pcie2_clk, pcie2_wake, pll_test, prng_rosc0, prng_rosc1, + prng_rosc2, prng_rosc3, pta, pwm0, pwm1, pwm2, pwm3, + qdss_cti_trig_in_a0, qdss_cti_trig_in_a1, qdss_cti_trig_in_b0, + qdss_cti_trig_in_b1, qdss_cti_trig_out_a0, + qdss_cti_trig_out_a1, qdss_cti_trig_out_b0, + qdss_cti_trig_out_b1, qdss_traceclk_a, qdss_traceclk_b, + qdss_tracectl_a, qdss_tracectl_b, qdss_tracedata_a, + qdss_tracedata_b, qspi_data, qspi_clk, qspi_cs, resout, rx0, + rx1, sdc_data, sdc_clk, sdc_cmd, tsens_max, wci_txd, wci_rxd, + wsi_clk, wsi_clk3, wsi_data, wsi_data3, wsis_reset, xfem ] + + bias-pull-down: true + bias-pull-up: true + bias-disable: true + drive-strength: true + input-enable: true + output-high: true + output-low: true + + required: + - pins + + additionalProperties: false + +required: + - compatible + - reg + +additionalProperties: false + +examples: + - | + #include <dt-bindings/interrupt-controller/arm-gic.h> + + tlmm: pinctrl@1000000 { + compatible = "qcom,ipq5332-tlmm"; + reg = <0x01000000 0x300000>; + gpio-controller; + #gpio-cells = <0x2>; + gpio-ranges = <&tlmm 0 0 53>; + interrupts = <GIC_SPI 249 IRQ_TYPE_LEVEL_HIGH>; + interrupt-controller; + #interrupt-cells = <0x2>; + + serial0-state { + pins = "gpio18", "gpio19"; + function = "blsp0_uart0"; + drive-strength = <8>; + bias-pull-up; + }; + }; -- 2.17.1
