I think you're looking for something in line with: "^gpio[0-9]|[1-9][0-9]|1[0-2][0-9]|13[0-2]$" > + - enum: [ sdc1_clk, sdc1_cmd, sdc1_data, sdc2_clk, sdc2_cmd, sdc2_data ] > + minItems: 1 > + maxItems: 36 > + > + function: > + description: > + Specify the alternative function to be configured for the specified > + pins. > + > + enum: [ adsp_ext, agera_pll, atest_char, atest_char0, atest_char1, > + atest_char2, atest_char3, atest_tsens, atest_tsens2, atest_usb1, > + atest_usb10, atest_usb11, atest_usb12, atest_usb13, atest_usb2, > + atest_usb20, atest_usb21, atest_usb22, atest_usb23, aud_sb, > + audio_ref, cam_mclk, cci_async, cci_i2c, cci_timer0, cci_timer1, > + cci_timer2, cci_timer3, cci_timer4, copy_gp, copy_phase, cri_trng, > + cri_trng0, cri_trng1, dbg_out, ddr_bist, ddr_pxi0, ddr_pxi1, > + ddr_pxi2, ddr_pxi3, debug_hot, dmic0_clk, dmic0_data, dmic1_clk, > + dmic1_data, dp_hot, edp_hot, edp_lcd, gcc_gp1, gcc_gp2, gcc_gp3, > + gp_pdm0, gp_pdm1, gp_pdm2, gpio, gps_tx, jitter_bist, ldo_en, > + ldo_update, m_voc, mclk1, mclk2, mdp_vsync, mdp_vsync0, mdp_vsync1, > + mdp_vsync2, mdp_vsync3, mdp_vsync4, mdp_vsync5, mpm_pwr, mss_lte, > + nav_pps, pa_indicator, phase_flag0, phase_flag1, phase_flag10, > + phase_flag11, phase_flag12, phase_flag13, phase_flag14, phase_flag15, > + phase_flag16, phase_flag17, phase_flag18, phase_flag19, phase_flag2, > + phase_flag20, phase_flag21, phase_flag22, phase_flag23, phase_flag24, > + phase_flag25, phase_flag26, phase_flag27, phase_flag28, phase_flag29, > + phase_flag3, phase_flag30, phase_flag31, phase_flag4, phase_flag5, > + phase_flag6, phase_flag7, phase_flag8, phase_flag9, pll_bist, > + pll_bypassnl, pll_reset, pri_mi2s, pri_mi2s_ws, prng_rosc, qca_sb, > + qdss_cti, qdss_gpio, qdss_gpio0, qdss_gpio1, qdss_gpio10, qdss_gpio11, > + qdss_gpio12, qdss_gpio13, qdss_gpio14, qdss_gpio15, qdss_gpio2, > + qdss_gpio3, qdss_gpio4, qdss_gpio5, qdss_gpio6, qdss_gpio7, qdss_gpio8, > + qdss_gpio9, qlink_enable, qlink_request, qua_mi2s, qui_mi2s, qup00, > + qup01, qup02, qup03, qup04, qup10, qup11, qup12, qup13, qup14, > + sd_write, sec_mi2s, sp_cmu, swr_rx, swr_tx, ter_mi2s, tgu_ch0, > + tgu_ch1, tgu_ch2, tgu_ch3, tsense_pwm, uim1_clk, uim1_data, > + uim1_present, uim1_reset, uim2_clk, uim2_data, uim2_present, > + uim2_reset, unused1, unused2, usb_phy, vfr_1, vsense_trigger, > + wlan1_adc0, wlan1_adc1, wlan2_adc0, wlan2_adc1, wsa_clk, wsa_data ] > + > + > + bias-disable: true > + bias-pull-down: true > + bias-pull-up: true > + drive-strength: true > + input-enable: true > + output-high: true > + output-low: true > + > + required: > + - pins > + - function > + > + additionalProperties: false > + > +examples: > + - | > + #include <dt-bindings/interrupt-controller/arm-gic.h> > + pinctrl@500000 { > + compatible = "qcom,sm6125-pinctrl"; s/pinconf/tlmm/ > + reg = <0x00500000 0x400000>, > + <0x00900000 0x400000>, > + <0x00d00000 0x400000>; > + reg-names = "west", "south", "east"; > + interrupts = <GIC_SPI 227 IRQ_TYPE_LEVEL_HIGH>; > + gpio-controller; > + gpio-ranges = <&tlmm 0 0 134>; > + #gpio-cells = <2>; > + interrupt-controller; > + #interrupt-cells = <2>; > + > + sdc2_state_on: sdc2-on { Per the binding the node name needs to end in "-state". > + pinconf-clk { There's no risk of name collisions in the state, so you should drop the "pinconf-" prefix.
