Subject: [PATCH] fix-pcf50633-move-charger-enable-decision-to-pcf50633_usb_curlim_set.patch
|
||
|
|
|
||
|
|
At the moment we ended up enabling and disabling the charger
|
||
|
|
at the time we service USBINS and USBREM events in the ISR.
|
||
|
|
|
||
|
|
We did that in machine specific code, but really it is PMU
|
||
|
|
specific decision, so this patch moves it into PMU code.
|
||
|
|
|
||
|
|
We enabled and disabled the charge immediately we saw the
|
||
|
|
interrupt event from PMU, yet we deferred setting charging
|
||
|
|
state based on ID and USB enumeration until at least after a
|
||
|
|
PMU ADC read that was handled in a second interrupt later.
|
||
|
|
|
||
|
|
Now the timing is unified to after we determined the charger
|
||
|
|
type and we enable and disable right there.
