certain networking subsystem (nss) clocks.

6357efe3ab clk: qcom: ipq9574: Update the alpha PLL type for GPLLs
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.

a4f9285520 This a large collection of clk driver updates and a handful of new SoC
clk driver support. We have the usual Qualcomm clk drivers, along with
 clk drivers for the Sophgo and T-Head vendors, all to support some new
 SoCs.
 
 Nothing in particular stands out to me in the updates. There's the
 interconnect clk driver which exposes clks as interconnects, crossing
 subsystems. There's a bunch of janitorial things that are improving
 drivers in general like kmemdup_array() or fixing error paths. But
 overall the updates look normal to fix the description data which is
 usually the stuff that's wrong and/or untested.
 
 I really wanted to land a bunch of KUnit clk code that I've been working
 on whenever I get some free time but it turned into a pumpkin at the
 last minute so I dropped those patches. I'll let it soak in linux-next
 after the merge window closes. I have a suspicion that we're going to
 need to totally rework the clk framework to fix structural issues like
 locking, clk rate setting, and runtime PM usage. Having a bunch of unit
 tests for that will help make sure that all keeps working.
 
 Core:
  - Skip gate basic type KUnit tests on s390 due to lack of MMIO emulation
 
 New Drivers:
  - AP sub-system clock controller in the T-Head TH1520
  - Sophgo Sophon sg2042 clk driver
  - Qualcomm SM7150 camera, display and video clk drivers
  - Qualcomm QCM2290 GPU clk driver
  - Qualcomm QCS8386/QCS8084 NSS clk driver
  - Qualcomm SM8650 camera and video drivers
 
 Updates:
  - Add reset support to Airoha EN7581 clk driver
  - Add MODULE_DESCRIPTIONs to various clk drivers
  - Introduce helper logic to expose clock controllers as simple
    interconnect providers
  - Use the interconnect helper above on Qualcomm ipq9574
  - Add CLK_SET_RATE_PARENT to the remaining USB pipe clocks on Qualcomm
    X1Elite
  - Improve error handling in Qualcomm kpss-xcc driver
  - Mark Qualcomm SC8280XP LPASS clock controller regmap_config const
  - Export more clocks for Rockchip rk3128 peripherals
  - Convert Rockchip clk drivers to use kmemdup_array()
  - Drop CLK_NR_CLKS from Rockchip rk3128 and rk3188 binding headers
  - Make qcom_cc_really_probe() take a struct device to allow reuse in
    non-platform-drivers
  - Introduce prepare-only branch clock ops in the qcom clk driver to
    support clocks on buses that take locks
  - Describe parent/child relationship for Qualcomm SC7280 camera GDSCs
  - Support Qualcomm Huayra 2290 alpha PLL
  - Adjust the highest SDCC clock frequency on Qualcomm IPQ6018 to match
    HS200 support
  - Add missing PCIe PIPE clocks on Qualcomm IPQ9574
  - Fix various configurations and properties in the Qualcomm SA8775P,
    X1E80100 and SM7280 drivers
  - Park Qualcomm SM8350 GPU RCGs on XO while disabled
  - Remove unused CONFIG_QCOM_RPMCC Kconfig symbol
  - exynos-clkout: Remove usage of of_device_id table as .of_match_table,
    because the driver is instantiated as MFD cell, not as standalone platform
    driver.  Populated .of_match_table confused people few times to convert the
    code to device_get_match_data(), which broke the driver
  - Mark one Samsung UFS clock as critical, because having it off stops the
    system from shutdown
  - Use kmemdup_array() when applicable

72ceafb587 clk: qcom: gcc-ipq9574: Add BRANCH_HALT_VOTED flag
The crypto_ahb and crypto_axi clks are hardware voteable.
This means that the halt bit isn't reliable because some
other voter in the system, e.g. TrustZone, could be keeping
the clk enabled when the kernel turns it off from clk_disable().
Make these clks use voting mode by changing the halt check to
BRANCH_HALT_VOTED and toggle the voting bit in the voting register
instead of directly controlling the branch by writing to the branch
register. This fixes stuck clk warnings seen on ipq9574 and saves
power by actually turning the clk off.

Also changes the CRYPTO_AHB_CLK_ENA & CRYPTO_AXI_CLK_ENA
offset to 0xb004 from 0x16014.
