clk: imx: Select MXC_CLK for CLK_IMX8QXP

2023-10-04T08:13:58Z

If the i.MX8QXP clock provider is built-in but the MXC_CLK is built as module, build fails: aarch64-linux-ld: drivers/clk/imx/clk-imx8-acm.o: in function `imx8_acm_clk_probe': clk-imx8-acm.c:(.text+0x3d0): undefined reference to `imx_check_clk_hws' Fix that by selecting MXC_CLK in case of CLK_IMX8QXP.

To find this type of problem more easily in the future, also enable building on other platforms, as we do for the other i.MX clk drivers.

clk: imx: Select MXC_CLK for i.MX93 clock driver

2022-03-15T21:44:46Z

Most of the i.MX clock generic API is built by selecting MXC_CLK. Without it, the i.MX93 clock driver will fail to build: aarch64-linux-gnu-ld: drivers/clk/imx/clk-imx93.o: in function `imx93_clocks_probe': clk-imx93.c:(.text+0xa8): undefined reference to `imx_obtain_fixed_clk_hw' So fix this by selecting MXC_CLK for the CLK_IMX93.

Add i.MX93 clk driver. i.MX93 clk hardware design is different compared with i.MX8M. It supports 4 sources for each clk root and the sources are separated into a few groups, low speed/fast io/audio and etc. Reviewed-by: Abel Vesa Signed-off-by: Peng Fan Link: https://lore.kernel.org/r/20220228020908.2810346-6-peng.fan@oss.nxp.com [abel.vesa@nxp.com: Added missing module license and description] Signed-off-by: Abel Vesa

clk: imx: scu: fix MXC_CLK_SCU module build break

2020-12-07T21:54:00Z

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.
