Subject: [PATCH] [neo] Every access to GPIO bank B has to go through the shadow code
|
|
|
|
- Any setting of any PIN on bank B will undo the LED setting.
|
|
Introduce neo1973_gpb_set_pin to set the PIN in a way not losing
|
|
the LED or any other shadowed setting.
|
|
- Update users of GPBXY for gta01 and gta02.
|
|
|
