[PATCH V5 0/6] Support building i.MX ARMv7/ARMv8 platforms clock driver as module

From: Anson Huang
Date: Thu Jul 02 2020 - 11:27:27 EST


Nowdays, there are more and more requirements of building SoC specific
drivers as modules, such as Android GKI (generic kernel image), this
patch set supports building i.MX ARMv6/ARMv7 SoCs clock drivers as modules,

The CLK_IMXxxx is introduced for i.MX ARMv7 platforms in order to support
various build options, and i.MX1/2/3 platforms now still ONLY support built-in
as they are rarely used now.

Changes since V4:
- add empty function of imx_register_uart_clocks() for MODULE build, then
all earlycon related clock handler can be built-out for MODULE;
- add module build support for ARMv7 platforms, also add COMPILE_TEST for them;
- add COMPILE_TEST for ARMv8 platforms;
- keep using builtin_platform_driver() for i.MX8QXP clock driver.

Anson Huang (6):
clk: composite: Export clk_hw_register_composite()
clk: imx: Support module build for i.MX5/6/7 and vf610
clk: imx: Support building i.MX common clock driver as module
clk: imx: Add clock configuration for ARMv7 platforms
clk: imx8m: Support module build
clk: imx8qxp: Support building i.MX8QXP clock driver as module
