This patch series brings the files from Linux kernel to provide clocks support as it is used on the Linux kernel with common clock framework [CCF] setup.
This series also fixes several problems with current clocks and provides sandbox tests for functions addded to clk-uclass.c file.
Repository: https://github.com/lmajewski/u-boot-dfu/commits/CCF-v4
Changes in v4: - New patch - None - None - None - New patch - None - Port some more Linux code to facilitate imx8 code porting (most notably flags) - Explicitly use container_of() based macro to provide struct clk in various places (e.g. gate2, mux, etc) Following patches has been squashed: http://patchwork.ozlabs.org/patch/1093141/ http://patchwork.ozlabs.org/patch/1093142/ http://patchwork.ozlabs.org/patch/1093146/ - New patch
Changes in v3: - New patch - The rate information is now cached into struct clk field - The clk_get_parent() is used to get pointer to the parent struct clk - Replace -ENODEV with -ENOENT - Use **clkp instead of **c - New patch - New patch
