[PATCH 0/8] Support i.MX8 SoCs pinctrl drivers built as module

[Anson Huang]

There are more and mroe requirements that SoC specific modules should be
built as module in order to support generic kernel image, such as Android
GKI concept.

This patch series supports i.MX8 SoCs pinctrl drivers to be built as module,
including i.MX8MQ/MM/MN/MP/QXP/QM/DXL SoCs.

Anson Huang (8):
  pinctrl: imx: Export necessary APIs for i.MX pinctrl drivers
  pinctrl: imx8mm: Support building as module
  pinctrl: imx8mn: Support building as module
  pinctrl: imx8mq: Support building as module
  pinctrl: imx8mp: Support building as module
  pinctrl: imx8qxp: Support building as module
  pinctrl: imx8qm: Support building as module
  pinctrl: imx8dxl: Support building as module
