| Subject | [PATCH v3 5/5] gpio: tps65912: Add GPIO driver for the TPS65912 PMIC |
| Message-ID | <qcga7-6cP-35@gated-at.bofh.it> |
This patch adds support for the TPS65912 PMIC GPIOs.
TPS65912 has five configurable GPIOs that can be used for several
purposes.

Nit: I'd suggest to put gpio_chip as the first member of your struct
so that to_gpio() resolves to the same address. This may make the
generated code neglectably smaller and faster.

Nit2: Maybe a more specific name (like tps_gpio()) would be better?
It's local to this file though, so not a big deal.

Nice and simple driver - my remarks above should not be taken as a
call to re-spin, just consider them if you need to send another
version of this patchset.
