dcf2cee77f clk: clk_versaclock: Add support for versaclock driver
The driver is based on the Versaclock driver from the Linux code, but
due differences in the clock API between them, some pieces had to be
changed.

This driver creates a mux, pfd, pll, and a series of fod ouputs.

1d7993d1d0 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.

e585bef17f 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.

82a248df9a driver: clk: Add support for clocks on Armada 37xx
The drivers are based on Linux driver by Gregory Clement.

The TBG clocks support only the .get_rate method.
  - since setting rate is not supported, the driver computes the rates
    when probing and so subsequent calls to the .get_rate method do not
    read the corresponding registers again

The peripheral clocks support methods .get_rate, .enable and .disable.

  - the .set_parent method theoretically could be supported on some clocks
    (the parent would have to be one of the TBG clocks)

  - the .set_rate method would have to try all the divider values to find
    the best approximation of a given rate, and it doesn't seem like
    this should be needed in U-Boot, therefore not implemented

e80dac0ab8 ARC: clk: introduce HSDK CGU clock driver
Synopsys HSDK clock controller generates and supplies clocks to various
controllers and peripherals within the SoC.

Each clock has assigned identifier and client device tree nodes can use
this identifier to specify the clock which they consume. All available
clocks are defined as preprocessor macros in the
dt-bindings/clock/snps,hsdk-cgu.h header and can be used in device
tree sources.

f264e23572 clk: stm32f7: rename clk_stm32f7.c to clk_stm32f.c
Now that clk_stm32f7.c manages clocks for both STM32F4 and F7 SoCs
rename it to a more generic clk_stm32f.c

Fix also some checkpatch errors/warnings.

36c2ee4ce5 clk: rmobile: Add RCar Gen3 clock driver
Add clock driver for the RCar Gen3 R8A7795 and R8A7796 SoCs .
This driver allows reading out the clock configuration set by
previous boot stages and enabling and disabling clock using
the MSTP registers. Setting clock is not supported thus far.

Add a clock framework driver for the zynq platform. The driver is based
on the platform zynq clock driver but reworked to use static functions
instead of run-time generated objects even for unused clocks.
Additionally the CONFIG_ZYNQ_PS_CLK_FREQ is replaced by the
ps-clk-frequency from the device tree.

d9fd7008f4 clock: add Tegra186 clock driver
In Tegra186, on-SoC clocks are manipulated using IPC requests to the BPMP
(Boot and Power Management Processor). This change implements a driver
that does that. A tegra/ sub-directory is created to follow the existing
pattern. It is unconditionally selected by CONFIG_TEGRA186 since virtually
any Tegra186 build of U-Boot will need the feature.
