Subject: [PATCHv2 0/3] Add support for suspend clk for Exynos5422 SoC

Seried build and tested on linux next-20200228.

This patch series tries to enable suspend clk using
exynos dwc3 driver, for this I have added new
compatible string "samsung,exynos5420-dwusb3"
so that we could add new suspend clk in addition
to the core clk. exynos dwc3 driver will help
enable/disable these clk.

This series PatchV2.
--Added the clk names for exynos5420 compatible.
--Added missing support for Exyno5410 SoC suspend clock.
--Update the commit message to support suspend clk usages.

---
Long time ago I tried to add suspend clk for dwc3 phy
which was wrong appoch, see below.
