This patch set is to add a subcommand 'release' to the 'cpu' command in cmd/cpu.c, making the command is able to release a core to run baremetal and RTOS applications.
Fixed some problems of the imx8_cpu.c and added i.MX 8M series SoCs support.
Added ARM A53 core clock registration in clock driver of i.MX 8M Mini, Nano and Plus SoCs.
And enabled the 'cpu' command and imx CPU driver for i.MX 8M series EVK boards and i.MX 93 EVK board.
Hou Zhiqiang (14): clk: imx8m: register ARM A53 core clock cpu: add release_core callback cpu: sandbox: implement release_core callback test: cpu: add test for release CPU core. cpu: imx: fix the CPU frequency in cpu_imx_get_info() cpu: imx: fix the CPU type field width cpu: imx: removed the tail '\n' of the CPU description cpu: imx: Add i.MX 8M series SoCs cpu: imx: implement release_core callback cmd: cpu: add release subcommand doc: cmd: add documentation for cpu command MAINTAINERS: add entry for cpu command configs: imx8m: enable the 'cpu' command configs: imx93: enable the 'cpu' command
--- V5: - Added cmd/cpu to doc/usage/index.rst to fix doc build failure. - Made the i.MX8M core clock CLK_IS_CRITICAL. V4: - Moved the depended patch into this thread. - Removed the tail '\n' of the CPU description for imx CPU driver. - Refined the documentation of 'cpu' command. V3: - Added documentation for 'cpu' command. - Fixed the getting cpu frequency issue in i.MX CPU driver. V2: - Implemented release_core() in sandbox and added test for the new API. - Increased the CPU type mask in i.MX CPU driver. - Added i.MX 8M series SoCs in i.MX CPU driver
