Hi:
I get the information is that : the i2c_cam_clk & i2c_cam_dat on i2c@3180000 which’s alias is “cam_i2c”.
what about i2c_gp0_clk,i2c_gp0_dat i2c_gp2_clk,i2c_gp2_dat i2c_gp3_clk,i2c_gp3_dat ?
I mean,I just want to get the address of i2c@???, like 3180000.
I read /soc/t18x/kernel-dts/tegra186-soc/tegra186-soc-i2c.dtsi,I could’t found the aliases gen0_i2c ,gen3_i2c.
I use this command: find -name “*.dtsi” | xargs grep “gen3_i2c”,also found nothing.
I get the address of i2c_gp0_clk & i2c_gp0_dat is 0xc240000,but do not know the address of i2c_gp2_clk & i2c_gp2_dat , i2c_gp3_clk & i2c_gp3_dat ,and there are on J26 of tx2 carrey board.
You can figure it out by the pimux table from download center.
The field A is the pin name on the carrier board. The field H is the function pin.
From below the GP2 is I2c7 and it’s HW function name start from 1 you can get the software name by subtracted 1 the you got GP2 is I2c6 and GP3 is i2c8. And you can get the address from the aliases.
