[U-Boot] [PATCH v4 00/13] clk: Port Linux common clock framework [CCF] to U-boot (tag: 5.0-rc3)

[Lukasz Majewski]

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.

Changes in v4:
- New patch
- 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)

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

Lukasz Majewski (13):
  clk: doc: Add documentation entry for Common Clock Framework [CCF]
    (i.MX)
  dm: Fix documentation entry as there is no UCLASS_CLOCK uclass
  clk: Remove clock ID check in .get_rate() of clk_fixed_*
  clk: Extend struct clk to provide information regarding clock rate
  clk: Extend struct clk to provide clock type agnostic flags
  clk: Provide struct clk for fixed rate clock (clk_fixed_rate.c)
  dm: clk: Define clk_get_parent() for clk operations
  dm: clk: Define clk_get_parent_rate() for clk operations
  dm: clk: Define clk_get_by_id() for clk operations
  clk: test: Provide unit test for clk_get_by_id() method
  clk: test: Provide unit test for clk_get_parent_rate() method
  clk: Port Linux common clock framework [CCF] for imx6q to U-boot (tag:
    5.0-rc3)
  dm: clk: Extend clk_get_parent_rate() to support CLK_GET_RATE_NOCACHE
    flag
