Subject: [PATCH 0/9] Support building i.MX8 SoCs clock driver as module

Nowdays, there are more and more requirements of building SoC specific
drivers as modules, such as Android GKI (generic kernel image), this patch
set support building i.MX8 SoCs clock drivers as modules, including
i.MX8MQ/MM/MN/MP/QXP, the common clock modules are: mxc-clk.ko for
i.MX8MQ/MM/MN/MP, mxc-clk-scu.ko for i.MX8QXP and later SoCs with SCU inside,
normally, each platform can ONLY insmod 1 common i.MX clock driver and
its own SoC clock driver.

Since i.MX common clk driver will support module build and no longer selected
by default, so for i.MX ARMv7 platforms, need to manually select it to
make build pass.

Anson Huang (9):
clk: composite: Export clk_hw_register_composite()
ARM: imx: Select MXC_CLK for ARCH_MXC
clk: imx: Support building SCU clock driver as module
clk: imx: Support building i.MX common clock driver as module
clk: imx8mm: Support module build
clk: imx8mn: Support module build
clk: imx8mp: Support module build
clk: imx8mq: Support module build
clk: imx8qxp: Support module build
