[PATCH v2 0/2] clk: samsung: exynos990: Fix PERIS gate clock parents and add TMU_SUB

[Denzeel Oliva]

Fix PERIS CMU gate clock parent mismatches and add the missing
TMU_SUB_PCLK clock.

Split into dt-bindings (clock ID) and driver (parent fixes) as
required by checkpatch.

Changes in v2:
  - Split dt-bindings header change into separate patch (1/2)
  - Driver fix now only touches clk-exynos990.c (2/2)
  - Add proper cover letter

v1: TODO-add-lore-link

[PATCH v2 2/2] clk: samsung: exynos990: Fix PERIS gate clock parents

[Denzeel Oliva]

Correct eight PERIS gate clock parents to match the hardware clock
tree, reorder the GIC mux parents, and add the missing TMU_SUB_PCLK
gate.

Separate commit. Fixing clock parents is something completely different
than adding new clock gate.
