H3 has additional PIO controller similar to what we can find on A23.
It's a 12 pin port, described in H3 Datasheet rev 1.1, pages 345-350.

h3-r-pinctrl comes after h3-pinctrl

This is probably wrong. According to other SoCs all R_ block peripherals
have clock gates and reset controls in the PRCM.

Extra new line here.

Also please split this into a separate patch.

This is problematic. 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.

Best regards,
Krzysztof Adamski

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,
