I can find information about reset and gates control for this peripheral on other SoCs user manuals but there is nothing about it in H3 User Manual (https://www.dropbox.com/s/nkr9slo1o9x6i1z/Allwinner_H3_Datasheet_V1.1.pdf?dl=0). Similarly, while I think I can find r_pio clock setup for A33: https://github.com/allwinner-zh/linux-3.4-sunxi/blob/master/drivers/clk/sunxi/clk-sun8iw5.c I can't find it for H3, though: https://github.com/allwinner-zh/linux-3.4-sunxi/blob/master/drivers/clk/sunxi/clk-sun8iw7.c Well, apart from this strange snippet: // binder r-pio CPUS_APB0_GATE to pio-clk's gate-reset-register clk = clk_get(NULL,"pio"); if(!clk || IS_ERR(clk)) printk("Error not get clk pio\n"); else { struct clk_hw *hw = __clk_get_hw(clk); struct sunxi_clk_periph *periph = to_clk_periph(hw); struct sunxi_clk_periph_gate *gate = &periph->gate; gate->reset = sunxi_clk_cpus_base+CPUS_APB0_GATE ; gate->rst_shift = 0; clk_put(clk); } Which I have to admit I don't fully understand. This seems to be setting reset line for first pio, not for r_pio - something we don't have right now. Or am I wrong here? I'm new to Allwinner SoCs, any help from veterans? Also, if that proves anything, I did test this code on OrangePi PC and PL ports works so their clock is enabled, for sure.

I did some tests and indeed, when I disabled PIO clock (bus_gates 69), R_PIO was still working while PIO did not. So I tryied to take the same address other SoCs are using (0x01f01468 - CPUS_APB0 register) and clearing 1st bit (which is enabled by default) disables R_PIO. So, well, it seems that this works the same as on other sunxi SoCs. I'll try doing proper change. Best regards, Krzysztof Adamski ^ permalink raw reply [flat|nested] 5+ messages in thread
