dm: Add a clock uclass Clocks are an important feature of platforms and have become increasing complex with time. Most modern SoCs have multiple PLLs and dozens of clock dividers which distribute clocks to on-chip peripherals. Some SoC implementations have a clock API which is private to that SoC family, e.g. Tegra and Exynos. This is useful but it would be better to have a common API that can be understood and used throughout U-Boot. Add a simple clock API as a starting point. It supports querying and setting the rate of a clock. Each clock is a device. To reduce memory and processing overhead the concept of peripheral clocks is provided. These do not need to be explicit devices - it is possible to write a driver that can adjust the I2C clock (for example) without an explicit I2C clock device. This can dramatically reduce the number of devices (and associated overhead) in a complex SoC. Clocks are referenced by a number, and it is expected that SoCs will define that numbering themselves via an enum. Signed-off-by: Simon Glass <sjg@chromium.org>

This allows drivers to be provided for clock generators, including
oscillators and PLLs. Devices can use a common clock API to request
a particular clock rate and check on available clocks. Clocks can
feed into other clocks in a tree structure, with multiplexers to
choose the source for each clock.

If this is acceptable and you have a need to use clock drivers in
SPL, enable this option. It might provide a cleaner interface to
setting up clocks within SPL, and allows the same drivers to be
used as U-Boot proper.

clk: Port Linux common clock framework [CCF] for imx6q to U-boot (tag: v5.1.12) This patch brings the files from Linux kernel (linux-stable/linux-5.1.y SHA1: 5752b50477da)to provide clocks support as it is used on the Linux kernel with Common Clock Framework [CCF] setup. The directory structure has been preserved. The ported code only supports reading information from PLL, MUX, Divider, etc and enabling/disabling the clocks USDHCx/ECSPIx depending on used bus. Moreover, it is agnostic to the alias numbering as the information about the clock is read from the device tree. One needs to pay attention to the comments indicating necessary for U-Boot's driver model changes. If needed, the code can be extended to support the "set" part of the clock management.

clk: Introduce TI System Control Interface (TI SCI) clock driver Some TI Keystone 2 and K3 family of SoCs contain a system controller (like the Power Management Micro Controller (PMMC) on 66AK2G SoCs and the Device Management and Security Controller on AM65x SoCs) that manage the low-level device control (like clocks, resets etc) for the various hardware modules present on the SoC. These device control operations are provided to the host processor OS through a communication protocol called the TI System Control Interface (TI SCI) protocol. This patch adds a clock driver that communicates to the system controller over the TI SCI protocol for performing clock management of various devices present on the SoC. Various clock functionality is achieved by the means of different TI SCI device operations provided by the TI SCI framework. This code is loosely based on the drivers/clk/keystone/sci-clk.c driver of the Linux kernel.
