ef4923c8e0 clk: samsung: exynos7885: do not define number of clocks in bindings
Number of clocks supported by Linux drivers might vary - sometimes we
add new clocks, not exposed previously.  Therefore these numbers of
clocks should not be in the bindings, as that prevents changing them.

Define number of clocks per each clock controller inside the driver
directly.

a96cbb146a clk: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

ef80c95c29 clk: samsung: exynos7885: Correct "div4" clock parents
"div4" DIVs which divide PLLs by 4 are actually dividing "div2" DIVs by
2 to achieve a by 4 division, thus their parents are the respective
"div2" DIVs. These DIVs were mistakenly set to have the PLLs as parents.
This leads to the kernel thinking "div4"s and everything under them run
at 2x the clock speed. Fix this.

0e1b2f1fb2 clk: samsung: exynos7885: Add TREX clocks
TREX D Core and P core clocks seem to be related to the BTS (Bus Traffic
Shaper) inside the Exynos7885 SoC, and are needed for the SoC to
function correctly.

When clocks are cut from TREX D Core, the eMMC and the framebuffer stops
working properly. Other unknown things may stop working as well.

When clocks are cut from TREX P Core, the system locks up needing a hard
reset.

Add these clocks and mark them critical so that they are always on.

f392db97b7 clk: samsung: exynos7885: Implement CMU_FSYS domain
CMU_FSYS clock domain provides clocks for FSYS IP-core providing clocks
for all MMC devices on Exynos7885, and USB30DRD.

Add clocks:
  - Bus clocks in CMU_TOP needed for CMU_FSYS
  - All clocks in CMU_FSYS needed for MMC devices

45bd8166a1 clk: samsung: Add initial Exynos7885 clock driver
This is an initial implementation adding basic clocks, such as UART,
USI, I2C, WDT, ect. and their parent clocks. It is heavily based on the
Exynos850 clock driver at 'drivers/clk/samsung/clk-exynos850.c' which
was made by Sam Protsenko, thus the copyright and author lines were
kept.

Bus clocks are enabled by default as well to avoid hangs while trying to
access CMU registers.

Only the parts of CMU_TOP needed for CMU_CORE and CMU_PERI, a bit of
CMU_CORE, and most of CMU_PERI is implemented as of now.
