Subject: [PATCH 48/90] gpio: axp: Bind via device tree
|
|
|
|
Now that the PMIC has a DM driver and binds device tree subnodes, the
|
|
GPIO device can be bound that way, instead of from inside board code.
|
|
|
|
Since the driver still uses the single set of register definitions from
|
|
axpXXX.h (as selected by AXPxxx_POWER), it does not differentiate among
|
|
the supported compatibles.
