Subject: [PATCH v2 0/2] add Watchdog Timer delay support for BQ24735
Date: Tue, 6 Jul 2021 16:55:25 -0300 [thread overview]
Message-ID: <20210706195527.371108-1-bmeneg@redhat.com> (raw)
The IC BQ24735 has the ability to suspend the battery charging in case the
system freezes for some reason: the IC observes consecutive writes for
either CargeCurrent of ChargVoltage registers in a maximum period of time.
This period of time can be configured by the user through the ChargeOption
register in the bits 13 and 14, but it's only possible to change if the user
sends the value directly accessing the I2C bus through userspace, because
the kernel driver doesn't read or write to the Watchdog bits.
This patchset enables the user to configure the value through the
device-tree option "ti,wdt-timeout".
