[PATCH 1/2] dt-bindings: clock: exynos850: Add TMU clock

[Sam Protsenko]

Add a constant for TMU PCLK clock. It acts simultaneously as an
interface clock (to access TMU registers) and an operating clock which
makes TMU IP-core functional.

[PATCH 2/2] clk: samsung: exynos850: Add TMU clock

[Sam Protsenko]

Add TMU PCLK clock in CMU_PERI unit. It acts simultaneously as an
interface clock (to access TMU registers) and an operating clock which
makes TMU IP-core functional.
