https://bugzilla.kernel.org/show_bug.cgi?id=213579 --- Comment #28 from wse@xxxxxxxxxxxxxxxxxxx --- I found a schematic for the Clevo NH5xHP According to that the touchpad is connected with 3 wires to the EC and with 3 wires to the CPU (and to vcc and gnd ofc): TP_CLK -> GPF4/PS2CLK2/5VT (EC) TP_DATA -> GPF5/PS2DAT2/5VT (EC) TP_I2C_CLK -> BD21 -> GPP_C17/I2C0_SCL TP_I2C_DAT -> BC22 -> GPP_C16/I2C0_SDA LID_SW# -> GPB1/LID_SW# (EC) TP_ATTN# -> BC48 -> GPP_R12/CLKOUT_48 Looking at https://elixir.bootlin.com/linux/v5.13/source/drivers/pinctrl/intel/pinctrl-tigerlake.c the CPU pins are: PINCTRL_PIN(37, "CLKOUT_48"), PINCTRL_PIN(121, "I2C0_SDA"), PINCTRL_PIN(122, "I2C0_SCL"), I hope this information helps. -- You may reply to this email to add a comment.
