This patchset adds the clock & reset driver support for i.MX8ULP.
For some of the PCC slot, As there is a SWRST control bit share
the same pcc register for peripheral reset ccontrol. To simplify
the case, register the pcc reset controller driver when pcc
clock driver is registered.
Patch 1/9 for the dt-bindings part is send out for review previously
with the dts patchset:
https://patchwork.kernel.org/project/linux-arm-kernel/cover/20210607083921.2668568-1-ping.bai@nxp.com/
Shawn suggests to send out the clock driver part firstly, so this
patch is included in this patchset for now.
v3 changes:
- split the clock dt schema file into two file, one for pcc, one for cgc
v2 changes:
- remove the useless clocks & clock-names from the dt-binding doc
- remove the redundant fixed clock register.

Add the clock dt-binding file for i.MX8ULP.
For pcc node, it will also be used as a reset controller,
so add the '#reset-cells' property description and add the
pcc reset IDs.

v3 changes:
- split into two binding file, one for pcc, one for cgc
v2 changes:
- removed the redundant clocks & clock-names property
v1 changes:
- Move this patch from dts patchset into this patchset

The PLLs used on i.MX8ULP is mostly the same as on i.MX7ULP,
except the PLL register offset is changed. Change the PLLv4
driver for code reuse on i.MX7ULP and i.MX8ULP.

On i.MX8ULP, some peripherals have a sw_rst control resides
in the per device PCC clock control register, all others are
same as i.MX7ULP, so update the 7ulp clock composite driver to
support i.MX8ULP to maxmimize the code reuse.

i.MX7ULP peripheral clock ONLY allow parent/rate to be changed
with clock gated, however, during clock tree initialization, the
peripheral clock could be enabled by bootloader, but the prepare
count in clock tree is still zero, so clock core driver will allow
parent/rate changed even with CLK_SET_RATE_GATE/CLK_SET_PARENT_GATE
set, but the change will fail due to HW NOT allow parent/rate change
with clock enabled. It will cause clock HW status mismatch with
clock tree info and lead to function issue. Below is an example:
usdhc0's pcc clock value is 0xC5000000 during kernel boot up, it
means usdhc0 clock is enabled, its parent is APLL_PFD1. In DT file,
the usdhc0 clock settings are as below:
assigned-clocks = <&pcc2 IMX7ULP_CLK_USDHC0>;
assigned-clock-parents = <&scg1 IMX7ULP_CLK_NIC1_DIV>;
when kernel boot up, the clock tree info is as below, but the usdhc0
PCC register is still 0xC5000000, which means its parent is still
from APLL_PFD1, which is incorrect and cause usdhc0 NOT work.
nic1_clk 2 2 0 176000000 0 0 50000
usdhc0 0 0 0 176000000 0 0 50000
After making sure the peripheral clock is disabled during clock tree
initialization, the usdhc0 is working, and this change is necessary
for all i.MX7ULP peripheral clocks.

For the imx_composite-7ulp clock type, The clock parent should
be changed explicitly by end user of this clock, if the the
'CLK_SET_RATE_NO_REPARENT' flag is not set, when user want to
set a clock frequency that can NOT get from HW accurately, then
the clock's parent will be switch to another clock parent sometimes.
This is NOT what we expected and introduced some additional debug
effort, so add the 'CLK_SET_RATE_NO_REPARENT' to avoid such unexpected
result.

It is possible that a PFD is enabled in HW but not in SW. That
means the enable count & prepare count of the PFD clock is '0',
so the 'CLK_SET_RATE' flag can do nothing when the rate is changed
while the PFD is hw enabled. In order to safely change the pfd
rate, we can disable the PFD directly if it is hw enabled but not
used by SW end user.

On i.MX8ULP, the 'CLK_SET_RATE_PARENT' flag should NOT be
set and according to the laest RM, the PFD divider value range
seems will be changed in the future, so update the pfdv2 to
include the specific support for i.MX8ULP.

On i.MX8ULP, for some of the PCCs, it has a peripheral SW RST bit
resides in the same registers as the clock controller. So add this
SW RST controller support alongs with the pcc clock initialization.
the reset and clock shared the same register, to avoid accessing
the same register by reset control and clock control concurrently,
locking is necessary, so reuse the imx_ccm_lock spinlock to simplify
the code.

v3 changes:
- remove the explict selection of 'RESET_CONTROLLER' in kconfig
- add some comments for the spinlock of reset driver
v2 changes:
- add 'Suggested-by' as suggested by Victor Liu

I believe this could be avoided entirely by having something like:
PCCx_RESETS_OFFSET + (index * 4)
and then:
#define PCC3_RESETS_OFFSET 0xa8
#define PCC4_RESETS_OFFSET 0x4
#define PCC5_RESETS_OFFSET 0xa0
#define PCC3_RESETS_NUM 13
#define PCC4_RESETS_NUM 17
#define PCC5_RESETS_NUM 14
Then we could pass on the PCCx_RESETS_OFFSET and the PCCx_RESETS_NUM and
that's it.

As you can see that the PCC offset that has reset is not consecutive in the register region.
So it will introduce hole in the index. And we can NOT use linear formula to calculate the offset directly.

The clk-imx8ulp.c file highly depends on the clock/reset index in this dt-binding patch.
