5635ef0bd1 clk: qcom: ipq5332: drop the CLK_SET_RATE_PARENT flag from GPLL clocks
GPLL clock rates are fixed and shouldn't be scaled based on the
request from dependent clocks. Doing so will result in the unexpected
behaviour. So drop the CLK_SET_RATE_PARENT flag from the GPLL clocks.

ccd8ab0306 clk: qcom: ipq5332: Drop set rate parent from gpll0 dependent clocks
IPQ5332's GPLL0's nominal/turbo frequency is 800MHz.
This must not be scaled based on the requirement of
dependent clocks. Hence remove the CLK_SET_RATE_PARENT
flag.

90d5c043dd clk: qcom: ipq5332: drop the gcc_apss_axi_clk_src clock
With the removal of the mem noc clocks in the commit e224dc703521 ("clk:
qcom: gcc-ipq5332: drop the mem noc clocks"), we can drop the
gcc_apss_axi_clk_src clock as well, since there are no clocks uses this
clock as a parent.

1784d031ef clk: qcom: ipq5332: drop the mem noc clocks
Due to the recent design changes, all the mem noc clocks will be
configured by the bootloaders and it will be access protected by the TZ
firmware. So drop these clocks from the GCC driver.

a96cbb146a clk: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

7510e80f4a clk: qcom: ipq5332: fix the order of SLEEP_CLK and XO clock
The order of DT_SLEEP_CLK and DT_XO are swapped and it is incorrect.
Due to which the clocks for which the parent should be XO is having parent
as SLEEP_CLK and vice versa. So fix the same by re-ordering the entries.

377c0b46d8 clk: qcom: ipq5332: mark GPLL4 as ignore unused temporarily
Clock framework disables the GPLL4 source since there are no active users
for this source currently. Some of the clocks initialized by the
bootloaders uses the GPLL4 as the source. Due to this, when the GPLL4 is
disabled by the clock framework, system is going for the reboot.

To avoid this, mark the GPLL4 as ignore unused so that clock framework
doesn't disable it. Once the users of this source is enabled, we can get
rid of this flag.

Add support for the global clock controller found on IPQ5332 SoC. PLL
used on IPQ5332 is of type Stromer Plus PLL, however the programming
sequence is same as Stromer PLL, so lets re-use the Stromer PLL ops.
