Please add when there is real need for it. Also it doesn't really make much sense to have index for both pctl and eint. Please define first entry of regs property as always pointing to pctl registers and by also eint registers for usual controllers. Then second regs entry would be eint registers for controllers with separate register blocks. Then there is only a need to have eint_res_idx in the driver and no need for pctl_res_idx, because it would be always 0.Ah, sorry, I got confused again by which registers are where in these GPF banks. Let's make it the other way around and make DT contain eint registers in first regs entry and hardcode eint_res_idx to 0 for the time being.I got with slight confusion. Do you mean that you want to remove the 'eint_res_idx' because it is always zero(0) as your comment. And do you agree to add 'pctl_res_idx'? Also, as you commented, the eint_res_idx for both GPA and GPFx is zero(0). Example: pinctrl_alive: pinctrl@10580000 { compatible = "samsung,exynos5433-pinctrl"; /* ALIVE domain , IMEM domain */ reg = <0x10580000 0x1a20>, <0x11090000 0x100>; wakeup-interrupt-controller { compatible = "samsung,exynos7-wakeup-eint"; interrupts = <GIC_SPI 16 0>; }; }; GPA's eint_res_idx is 0 GPA's pctl_res_idx is 0 GPFx's eint_res_idx is 0 GPFx's pctl_res_idx is 1
Yeah, that's right. I just want to avoid adding eint_res_idx until it is found to be really needed.
However it should be still beneficial to refactor the codequoted
and calculate per-bank eint_base to avoid adding the offset every time, similarly to pctl_base/offset, from my suggestion below.I agree. I'll modify it according to your comment.
Thanks. Looking forward to the patch. Best regards, Tomasz -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
