i.MX95 System Management Control Firmware(SCMI) manages the clock
function, it exposes PLL VCO which could support up to 5GHz rate that
exceeds UINT32_MAX. So add assigned-clock-rates-u64 support
to set rate that exceeds UINT32_MAX.

Add the Q6 BIMC, LPASS core/adsp SMMU clocks to support audio related
functionality on MSM8998 and APQ variants.
As a final step to entirely enable the required clock tree for the
lpass iommu and audio dsp, add the lpass core/adsp GDSCs.
As a side note, it was found out that disabling the lpass core GDSC
at any time would cause a system lockup (and reboot): disabling
this GDSC will leave the lpass iommu completely unclocked, losing
its state entirely - including the secure contexts that have been
previously set-up from the bootloader/TrustZone.
Losing this IOMMU configuration will trigger a hypervisor fault,
which will reboot the system; the only workaround for this issue
is to declare the lpass core gdsc as always-on.
It should also not be forgotten that this is all about firmware and
there may be a version of it that doesn't enable this GDSC at all
before booting Linux, which is the reason why this specific declaration
wasn't simply omitted.

Update PLL offsets to DEFAULT_EVO to configure MDIO to 800MHz.
The incorrect clock frequency leads to an incorrect MDIO clock. This,
in turn, affects the MDIO hardware configurations as the divider is
calculated from the MDIO clock frequency. If the clock frequency is
not as expected, the MDIO register fails due to the generation of an
incorrect MDIO frequency.
This issue is critical as it results in incorrect MDIO configurations
and ultimately leads to the MDIO function not working. This results in
a complete feature failure affecting all Ethernet PHYs. Specifically,
Ethernet will not work on IPQ9574 due to this issue.
Currently, the clock frequency is set to CLK_ALPHA_PLL_TYPE_DEFAULT.
However, this setting does not yield the expected clock frequency.
To rectify this, we need to change this to CLK_ALPHA_PLL_TYPE_DEFAULT_EVO.
This modification ensures that the clock frequency aligns with our
expectations, thereby resolving the MDIO register failure and ensuring
the proper functioning of the Ethernet on IPQ9574.

register using regmap_write() API in __alpha_pll_trion_set_rate
callback will override LUCID EVO PLL initial configuration related

Observed random PLL lock failures during PLL enable due to such

PLL_L_VAL bitfields in __alpha_pll_trion_set_rate callback.

In Exynos7885 (and seemingly all modern Exynos SoCs) all PLLs have a MUX
attached to them controlled by bit 4 in the PLL's CON0 register.
These MUXes can select between OSCCLK or the PLL's output, essentially
making the PLL bypassable.
These weren't modeled in the driver because the vendor provided drivers
didn't model it properly, instead setting them when updating the PMS
values.
Not having them modeled didn't cause any problems in this case, since
these MUXes were set to the PLL's output by default, but this is not the
case everywhere in this SoC.

Add support for hardware dividers for PLL IDs in sam9x7 SoC. The system
PLL - PLLA and the system PLL divided by 2 - PLLADIV2 with PLL ID 0 and
4 respectively, both have a hardware divider /2. This has to be taken into
account in the software to obtain the right frequencies. Support for the
same is added in the PLL driver.
fcorepllack -----> HW Div = 2 -+--> fpllack

+--> HW Div = 2 ---> fplladiv2ck
In this case the corepll freq is 1600 MHz. So, the plla freq is 800 MHz
after the hardware divider and the plladiv2 freq is 400 MHz after the
hardware divider (given that the DIVPMC is 0).

Fix seveal odd-looking places in SM8550's dispcc driver:
- duplicate entries in disp_cc_parent_map_4 and disp_cc_parent_map_5
- using &disp_cc_mdss_dptx0_link_div_clk_src as a source for
disp_cc_mdss_dptx1_usb_router_link_intf_clk
The SM8650 driver has been used as a reference.

The Zonda PLL has a 16 bit signed alpha and in the cases where the alpha
value is greater than 0.5, the L value needs to be adjusted accordingly.
Thus update the logic to handle the signed alpha val.

Currently, clk_zonda_pll_set_rate polls for the PLL to lock even if the
PLL is disabled. However, if the PLL is disabled then LOCK_DET will
never assert and we'll return an error. There is no reason to poll
LOCK_DET if the PLL is already disabled, so skip polling in this case.

Correct the pll postdiv shift used in clk_trion_pll_postdiv_set_rate
API. The shift value is not same for different types of plls and
should be taken from the pll's .post_div_shift member.
