mainlining shenanigans
i.MX7ULP has a Cortex-A7 CPU which can run in RUN mode or HSRUN mode, it is controlled in SMC1 module. The RUN mode and HSRUN mode will use different clock source for ARM, "divcore" for RUN mode and "hsrun_divcore" for HSRUN mode, so the control bits in SMC1 module can be abstracted as a HW clock mux, this patch adds HSRUN mode related clocks in SCG1 module and adds "arm" clock in SMC1 module to support RUN mode and HSRUN mode switch. Latest clock tree in RUN mode as below: firc 0 0 0 48000000 0 0 50000 firc_bus_clk 0 0 0 48000000 0 0 50000 hsrun_scs_sel 0 0 0 48000000 0 0 50000 hsrun_divcore 0 0 0 48000000 0 0 50000 sosc 3 3 3 24000000 0 0 50000 spll_pre_sel 1 1 1 24000000 0 0 50000 spll_pre_div 1 1 2 24000000 0 0 50000 spll 1 1 2 528000000 0 0 50000 spll_pfd0 1 1 1 500210526 0 0 50000 spll_pfd_sel 1 1 0 500210526 0 0 50000 spll_sel 1 1 0 500210526 0 0 50000 scs_sel 1 1 0 500210526 0 0 50000 divcore 1 1 0 500210526 0 0 50000 arm 1 1 0 500210526 0 0 50000 Signed-off-by: Anson Huang <Anson.Huang@nxp.com> Signed-off-by: Stephen Boyd <sboyd@kernel.org> |

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
