6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans de Goede <hdegoede@xxxxxxxxxx>
[ Upstream commit b3ded6072c5600704cfa3ce3a8dc8718d34bda66 ]
There are 2 issues with bq24296_set_otg_vbus():
1. When writing the OTG_CONFIG bit it uses POC_CHG_CONFIG_SHIFT which
should be POC_OTG_CONFIG_SHIFT.
2. When turning the regulator off it never turns charging back on. Note
this must be done through bq24190_charger_set_charge_type(), to ensure
that the charge_type property value of none/trickle/fast is honored.
Resolve both issues to fix BQ24296 Vbus regulator support not working.
