[PATCH 04/21] sh: select legacy gpiolib interface
Posted by Arnd Bergmann 1 month, 3 weeks ago
From: Arnd Bergmann <arnd@arndb.de>

Many board files on sh reference the legacy gpiolib interfaces that
are becoming optional. To ensure the boards can keep building, select
CONFIG_GPIOLIB_LEGACY on each of the boards that have one of the
hardcoded calls.

Is there a reason to have both rather than having GPIOLIB_LEGACY select 
GPIOLIB? (Does the legacy one ever NOT use the new one?)

The way I've staged the series was

1. add GPIOLIB_LEGACY as an always-enabled symbol in 6.17
2. add the 'select' and 'depends on' for that symbol in 6.18
3. turn it off for all configs that don't select it already

Having GPIOLIB_LEGACY select GPIOLIB does sound like a nice
idea in stage 3, but that doesn't work with the first step
that's already merged now.
