Not manually, no. Is that not done by the sunxi clock driver when preparing/enabling the clock? Also since the signal flatlined, I think clk_prepare_enable did *something*. (it probably switched away from the GPIO function; a shell script to simulate a poor-mans clock using GPIO was still running but the scope didn't show it anymore afterwards) (I thought clk_out_a was initially introduced by Chen-Yu Tsai for the Cubietruck Wifi but I can't find where the Wifi driver|dts muxes clk_out_a in 4.4-rc2 either) > Did you enable the clock? Back then, I enabled it very directly in <http://svn.nomike.com/playground/trunk/Navi/TSS463AA/Linux/tss463aa.c?p=5734>, search for "clk_prepare_enable". (I used the low clock rate so I could have seen it on my cheap scope if it worked) (Now it's nicer (but still doesn't work), <http://svn.nomike.com/playground/trunk/Navi/TSS463AA/Linux/tss463aa.c> - and it needs extra device tree attributes now) Thanks, Danny -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
