Series [v6,1/3] pinctrl: qcom: Kconfig: Rework PINCTRL_MSM to be a depenency rather then a selected config | expand

Commit Message

John Stultz Nov. 6, 2020, 4:27 a.m. UTC 
Tweaks to allow pinctrl-msm code to be loadable as a module.

This is needed in order to support having the qcom-scm driver,
which pinctrl-msm calls into, configured as a module.

This requires that we tweak Kconfigs selecting PINCTRL_MSM to
also depend on QCOM_SCM || QCOM_SCM=n so that we match the
module setting of QCOM_SCM.

v2:
* Module description and whitespace fixes suggested by Bjorn
* Added QCOM_SCM || QCOM_SCM=n bits on Kconfigs selecting
  PINCTRL_MSM. Reported by both Todd and Bjorn.
v3:
* Make sure the QCOM_SCM || QCOM_SCM=n trick is commented
v4:
* Rework "select PINCTRL_MSM" to "depends on PINCTRL_MSM"
  to consolidate the QCOM_SCM dependency.
v5:
* Add PINCTRL_MSM to arm64 defconfig
v6:
* Split PINCTRL_MSM dependency bit out into its own patch
