Merge tag 'samsung-clk-6.15' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into clk-samsung

Pull Samsung clk driver updates from Krzysztof Kozlowski:

 - Samsung Exynos990: Add support for the PERIS clock controller in existing
   driver
 - Samsung Exynos2200: Add new driver for several clock controllers (Alive,
   CMGP, HSI, PERIC/PERIS, TOP, UFS and VFS)
 - Samsung Exynos7870: Add new driver for several clock controllers (Alive,
   MIF, DISP AUD, FSYS, G3D, ISP, MFC and PERI)
 - 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.
 - Spelling and header inclusion cleanups

* tag 'samsung-clk-6.15' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux:
  clk: samsung: Drop unused clk.h and of.h headers
  clk: samsung: Add missing mod_devicetable.h header
  clk: samsung: add initial exynos7870 clock driver
  clk: samsung: introduce Exynos2200 clock driver
  clk: samsung: clk-pll: add support for pll_4311
  dt-bindings: clock: add clock definitions and documentation for exynos7870 CMU

+description: |
+  Exynos2200 clock controller is comprised of several CMU units, generating
+  clocks for different domains. Those CMU units are modeled as separate device
+  tree nodes, and might depend on each other. The root clocks in that root tree
+  are two external clocks: XTCXO (76.8 MHz) and RTCCLK (32768 Hz). XTCXO must be
+  defined as a fixed-rate clock in dts, whereas RTCCLK originates from PMIC.
+
+  CMU_TOP is a top-level CMU, where all base clocks are prepared using PLLs and
+  dividers; all other clocks of function blocks (other CMUs) are usually
+  derived from CMU_TOP.
+
+  Each clock is assigned an identifier and client nodes can use this identifier
+  to specify the clock which they consume. All clocks available for usage
+  in clock consumer nodes are defined as preprocessor macros in
+  'include/dt-bindings/clock/samsung,exynos2200-cmu.h' header.
