We had the discussion. This should be done via pinctrl irq if possible instead of
specifying WAKEUP_EN here, You had some trouble to understand how it can be done,
and we agreed to add the wakeup functionality as a follow-up concentrating just
on that detail and for now just remove WAKEUP_EN.
I think I may have understood what is to be done.
For example we have
pinctrl-single,pins = <
OMAP4_IOPAD(0x0bc, WAKEUP_EN | PIN_INPUT | MUX_MODE3)
quoted
;
for wlan_host_wake, so the change needed to be done is from
interrupt-parent = <&gpio3>;
interrupts = <17 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "host-wake";
pinctrl-names = "default";
pinctrl-0 = <&wlan_host_wake>;
we still need the pinctrl. Just the WAKEUP_EN flag gets managed via the
pinctrl interrupt handling.
to
\.
interrupts-extended = <&gpio3 17 IRQ_TYPE_LEVEL_HIGH>,
<&omap4_pmx_core 0x0bc>;
<&omap4_pmx_core 0x7c>
offset is from beginning of padconf area, so from
0x4A10 0040, you can see that from.
In omap4-l4.dtsi:
omap4_pmx_core: pinmux@40 {
compatible = "ti,omap4-padconf",
"pinctrl-single";
reg = <0x40 0x0196>;
The OMAP4_IOPAD macro handles the offset, so you have
different values there.
interrupt-names = "host-wake", "wakeup";
and remove the pinctrl?
just remove the WAKEUP_EN flag from there.
Similarly for all in the omap4_pmx_core domain (wifi, bt, i2c as the
drivers support it)
No chnages for &omap4_pmx_wkup domain
The gpio instance in that domain is always-on anyways, so we do not need
any additional wakeup mechanism there.
