Hi,

New clk drivers for Samsung SoC.  This pull includes drivers which you
commented later and pointed out few issues.  Pointed issues are in all Samsung
clk drivers and the ones here just copy existing patterns:

1. Headers: I fixed it for new and existing drivers and this pull request
includes the fixes.
2. device_get_match_data(): I still wait for contributors response. If they do
not respond, I will fix it for next cycle.
3. refdata and platform_driver_probe: I tried fixing it, but incomplete and
need to investigate more.

Best regards,
Krzysztof

  clk: samsung: Drop unused clk.h and of.h headers (2025-03-07 16:01:22 +0100)

----------------------------------------------------------------
Samsung SoC clock drivers changes for 6.15

1. Exynos990: Add support for the PERIS clock controller in existing
   driver.
2. Exynos2200: Add new driver for several clock controllers (Alive,
   CMGP, HSI, PERIC/PERIS, TOP, UFS and VFS).
3. Exynos7870: Add new driver for several clock controllers (Alive,
   MIF, DISP AUD, FSYS, G3D, ISP, MFC and PERI).
4. Correct undefined behavior / runtime array bounds check of flexible
   array member (last 'hws' element in 'struct clk_hw_onecell_data').
   The code was logically correct for normal case, but not for the
   clang/GCC runtime bounds checking of flexible array member.
5. Few cleanups: spelling, header inclusions.
