52b61c944c clk: move clk-ti-sci driver to 'ti' directory
The patch moves the clk-ti-sci.c file to the 'ti' directory along with
all the other TI's drivers, and renames it clk-sci.c.

215bd541b8 clk: ti: add support for clkctrl clocks
Until now the clkctrl clocks have been enabled/disabled through platform
routines. Thanks to this patch they can be enabled and configured directly
by the probed devices that need to use them.

58e1af972f clk: ti: add gate clock driver
The patch adds support for TI gate clock binding. The code is based on
the drivers/clk/ti/gate.c driver of the Linux kernel version 5.9-rc7.

ea45b8f28d clk: ti: add divider clock driver
The patch adds support for TI divider clock binding. The driver uses
routines provided by the common clock framework (ccf).

The code is based on the drivers/clk/ti/divider.c driver of the Linux
kernel version 5.9-rc7.

756d64e43e clk: ti: am33xx: add DPLL clock drivers
The digital phase-locked loop (DPLL) provides all interface clocks and
functional clocks to the processor of the AM33xx device. The AM33xx
device integrates five different DPLLs:
 * Core DPLL
 * Per DPLL
 * LCD DPLL
 * DDR DPLL
 * MPU DPLL

The patch adds support for the compatible strings:
 * "ti,am3-dpll-core-clock"
 * "ti,am3-dpll-no-gate-clock"
 * "ti,am3-dpll-no-gate-j-type-clock"
 * "ti,am3-dpll-x2-clock"

The code is loosely based on the drivers/clk/ti/dpll.c drivers of the
Linux kernel version 5.9-rc7.

d09f063a04 clk: ti: add mux clock driver
The driver manages a register-mapped multiplexer with multiple input
clock signals or parents, one of which can be selected as output. It
uses routines provided by the common clock framework (ccf).

The code is based on the drivers/clk/ti/mux.c driver of the Linux
kernel version 5.9-rc7.
