linux-toradex.git/include/linux/platform_data/gpio-davinci.h, branch v5.1-rc1 Linux kernel for Apalis and Colibri modules gpio: davinci: restore a way to manually specify the GPIO base 2018-11-26T11:15:10+00:00 Bartosz Golaszewski bgolaszewski@baylibre.com 2018-11-21T09:35:17+00:00 786a9ab1330169f2602238822b4df5d5c4c98f6c Commit 587f7a694f01 ("gpio: davinci: Use dev name for label and automatic base selection") broke the network support in legacy boot mode for da850-evm since we can no longer request the MDIO clock GPIO. Other boards may be broken too, which I haven't tested. The problem is in the fact that most board files still use the legacy GPIO API where lines are requested by numbers rather than descriptors. While this should be fixed eventually, in order to unbreak the board for now - provide a way to manually specify the GPIO base in platform data.

Commit 587f7a694f01 ("gpio: davinci: Use dev name for label and
automatic base selection") broke the network support in legacy boot
mode for da850-evm since we can no longer request the MDIO clock GPIO.

Other boards may be broken too, which I haven't tested.

The problem is in the fact that most board files still use the legacy
GPIO API where lines are requested by numbers rather than descriptors.

While this should be fixed eventually, in order to unbreak the board
for now - provide a way to manually specify the GPIO base in platform
data.
