[PATCH v4 0/4] clk: samsung: exynos990: CMU_TOP fixes (mux regs, widths, factors)

From: Denzeel Oliva

Hi,

Two small fixes for Exynos990 CMU_TOP:

Correct PLL mux register selection (use PLL_CON0), add DPU_BUS and
CMUREF mux/div, and update clock IDs.
Fix mux/div bit widths and replace a few bogus divs with fixed-factor
clocks (HSI1/2 PCIe, USBDP debug); also fix OTP rate.

Changes in v2:

- In the first commit the divratio of
PLL_SHARED0_DIV3 should not be changed.

Changes in v3:

- There is no ABI massive break, the new ID clocks are
in the last define CMU_TOP block.

Changes in v4:

- Fix compilation for define CLK_DOUT_CMU_CMUREF to
CLK_DOUT_CMU_CLK_CMUREF

Please review.
