[PATCH v2 1/3] ARM: imx: Allow user to disable pinctrl

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Making pinctrl drivers and subsequently the pinctrl framework
user-controllable, allows building a kernel without this.
While in many (most) cases, this could make the system unbootable, it
does allow building smaller kernels for those situations where picntrl
is not needed.

One such situation is when building a kernel for NXP LS1021A systems,
which does not have run-time controllable pinctrl, so pinctrl framework
and drivers are 100% dead-weight.
