Changes in v2:
- Removed name duplicates login, as pointed by Krzysztof Kozlowski
-Corrected the sequence of binding, driver and DT entries
- Removed <linux/mod_devicetable.h>, as pointed by Uwe
- Added all the TOP clocks in single patch
- Organised the patches in the order: dt-bindings → clk-driver → dtsi
- Added Automatic Clock Gating, as suggested by Peter Griffin
-Since we are adding ACG, we need to add SYSREG, hence, added that
- Followed the name mangling strategy as mentioned in clk-gs101
