Linuxdebugfs use the sharing software to view the gpio status

Linuxdebugfs you can use the sharing software to view the gpio status. adding debugfs to debugging can sometimes get twice the result with half the effort: adbshellmkdirdatadebugmount-tdebugfsdebugfsdatadebugcddatadebug check gpio status root @ android linux debugfs use sharing software to view gpio status add debugfs in debugging sometimes get twice the result with half the effort: adb shell # mkdir/data/debug # mount-t debugfs/data/debug # cd/data/debug view gpio status root @ android: /data/debugfs # cat gpioGPIOs 0-15: gpio-0 (front_camera_rst) out lo GPIOs 16-42: gpio-17 (tsl2771_int) in hi gpio-26 (ctp_reset) out hi gpio-29 (front_camera_pwd) out hi gpio-31 (gpio_kp_out) out lo gpio-32 (gpio_kp_out) out lo gpio-35 (GPIO_E186_POWER) in lo gpio-36 (gpio_kp_in) in hi gpio-37 (gpio_kp_in) in hi gpio-42 (hs_sw) in hi GPIOs 43-67: gpio-48 (ctp_irq) in hi gpio-60 (qup_scl) in hi gpio-61 (qup_sda) in hi GPIOs 68-94: gpio-76 (lis3dh_acc_int) in lo gpio-82 ([auto]) out hi gpio-85 (bahamsys_rst_n) in lo gpio-94 ([auto]) out hi GPIOs 95-106: gpio-97 (MDP_VSYNC) in lo GPIOs 107-132: gpio-107 (ctp_power) in hi gpio-115 (GPIO_E186_WAKEUP) in lo gpio-131 (qup_scl) in hi gpio-132 (qup_sda) in hi view regulatorroot @ android: /data/logs # Logs/dummy/ldo03/ldo06/logs/ldo12/ldo15/ldo18/smps1/smps4/logs/ldo04/ldo07/ldo10/ldo13/ldo16/ldo19/smps2 /ldo02/ldo05/ldo08/ldo11/ldo14/ldo17/ncp/smps3/root @ android: /data/debugfs # catregulator/ldo10/voltage 3000000 view clkroot @ android: /# cat/data/debugfs/clk/adm_clk/keys/adsp_clk/keys/ecodec_clk/keys/Secrets/gp_clk/sdc3_clk/cam_m_clk/kg_3d_clk/keys/ keys/kg_3d_p_clk/sdc4_clk/keys/csi1_clk/keys/csi1_p_clk/keys/uart1_clk/keys/debug_suspend tables/keys /empty/imem_clk/empty/dsi_clk/mdp_clk/empty/ebi1_clk/empty/usb_phy_clk/ebi2_clk/pbus_clk /vdc_clk/release/pcm_clk/vfe_clk/ebi_adm_clk/pmdh_clk/vfe_mdc_clk/release/sdac_clk/ebi_lcdc_clk/sdc1_clk/root @ android: /# cat/data/debugfs/clk/mdp_clk/rate 200000000
