clk: imx: add driver for imx8ulp's sim lpav

2025-11-11T16:01:25+00:00

The i.MX8ULP System Integration Module (SIM) LPAV module is a block control module found inside the LPAV subsystem, which offers some clock gating options and reset line assertion/de-assertion capabilities. Therefore, the clock gate management is supported by registering the module's driver as a clock provider, while the reset capabilities are managed via the auxiliary device API to allow the DT node to act as a reset and clock provider.

clk: imx: clk-audiomix: Add reset controller

2024-06-21T04:44:01+00:00

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.

clk: imx: Select MXC_CLK for CLK_IMX8QXP

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

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.
