cat /sys/kernel/debug/pinctrl/1000000.pinctrl/pinmux-functions | grep clk
returned the following -
function: cam_mclk0, groups = [ gpio26 ]
function: cam_mclk1, groups = [ gpio27 ]
function: dmic0_clk, groups = [ gpio0 ]
function: gcc_gp1_clk_a, groups = [ gpio49 ]
function: gcc_gp1_clk_b, groups = [ gpio97 ]
function: gcc_gp2_clk_a, groups = [ gpio50 ]
function: gcc_gp2_clk_b, groups = [ gpio12 ]
function: gcc_gp3_clk_a, groups = [ gpio51 ]
function: gcc_gp3_clk_b, groups = [ gpio13 ]
function: qdss_traceclk_a, groups = [ gpio46 ]
function: qdss_traceclk_b, groups = [ gpio5 ]
But I dont know how to get any of these clocks out on the pins. gpio12/13 are brought out on the Low speed connecter on the dragonboard. But, I dont know how to change the pinmux configurations on the pins to enable gcc_gp3_clk_b or gcc_gp2_clk_b.
