2024-06-21clk: imx: clk-audiomix: Add reset controllerShengjiu Wang1-0/+1
Audiomix block control can be a reset controller for Enhanced Audio Return Channel (EARC), which is one of modules in this audiomix subsystem. The reset controller is supported by the auxiliary device framework.

2020-12-08clk: imx: scu: fix MXC_CLK_SCU module build breakDong Aisheng1-2/+2
This issue can be reproduced by having a kernel config with CONFIG_IMX_MBOX=m and CONFIG_MXC_CLK_SCU=m. It's caused by the Makefile wanting to build clk-scu.o and clk-imx8qxp.o as different targets but that doesn't work (e.g. MXC_CLK_SCU = y while CLK_IMX8QXP = n) "obj-$(CONFIG_MXC_CLK_SCU) += clk-imx-scu.o clk-imx-lpcg-scu.o clk-imx-scu-$(CONFIG_CLK_IMX8QXP) += clk-scu.o clk-imx8qxp.o" Having MXC_CLK_SCU=y/m while CLK_IMX8QXP=n will cause a linker problem like below: LD [M] drivers/clk/imx/clk-imx-scu.o arm-poky-linux-gnueabi-ld: no input files Make MXC_CLK_SCU be un-selectable by users so it can only be selected by the CLK_IMX8QXP option, ensuring the two symbols are built together. Drop COMPILE_TEST too because this option isn't selectable anymore. We can remove it from MXC_CLK_SCU because CLK_IMX8QXP selects MXC_CLK_SCU which already has COMPILE_TEST.
