Subject: [PATCH 0/3] gpiolib: convert 'devprop_gpiochip_set_names' to support multiple gpiochip per device
Date: Thu, 8 Jul 2021 09:04:26 +0200 [thread overview]
Message-ID: <20210708070429.31871-1-sergio.paracuellos@gmail.com> (raw)
There are some unfortunate cases where the DT representation
of the device and the Linux internal representation differs.
Such drivers for devices are forced to implement a custom function
to avoid the core code 'devprop_gpiochip_set_names' to be executed
since in any other case every gpiochip inside will got repeated
names through its internal gpiochip banks. To avoid this antipattern
this changes are introduced trying to adapt core 'devprop_gpiochip_set_names'
to get a correct behaviour for every single situation.
This series introduces a new 'offset' field in the gpiochip structure
that can be used for those unfortunate drivers that must define multiple
gpiochips per device.
Drivers affected by this situation are also updated. These are
'gpio-mt7621' and 'gpio-brcmstb'.
Motivation for this series available at [0].
Thanks in advance for your feedback.
Best regards,
