The ACLK_BUS0/1/2 are used for NoC (Network on Chip). If NoC's clocks are disabled, the system halt happens. Following clocks must be always enabled: - CLK_ACLK_BUS0_400 : NoC's bus clock for PERIC/PERIS/FSYS/MSCL, - CLK_ACLK_BUS1_400 : NoC's bus clock for MFC/HEVC/G3D, - CLK_ACLK_BUS2_400 : NoC's bus clock for GSCL/DISP/G2D/CAM0/CAM1/ISP. This patch also adds the CLK_SET_RATE_PARENT flag to the CLK_SCLK_JPEG_MSCL because this clock should be used for bus frequency scaling. This clock need to be changed on the fly with CLK_SET_RATE_PARENT flag. Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
