832685f07c clk: mediatek: use unsigned type for returning the clk rate
mtk_clk_find_parent_rate is calling clk_get_rate to know the rate
of a parent clock. clk_get_rate returns a ulong, while
mtk_clk_find_parent_rate returns an int. This implicit cast creates
an issue for clock rates big enough to need the full 32 bits to
store its data. When that happen the clk rate will become incorrect
because of the implicit cast between ulong -> int -> ulong.

This commit change the return type of mtk_clk_find_parent_rate to
ulong.

2d88b5a38e clk: MediaTek: add hifsys entry for MT7623 SoC.
This adds high speed interface subsystem - hifsys (i.e. PCIe and USB)
for MT7623 SoC and enables its reset controller.

The control block is shared with ethsys and accordingly rename the
related defines.

0bd7dc74d2 clk: MediaTek: add clock driver for MT7629 SoC.
This patch adds clock modules for MediaTek SoCs:
- Shared part: a common driver which contains the general operations
for plls, muxes, dividers and gates so that we can reuse it in future.

- Specific SoC part: the group of structures used to hold the hardware
configuration for each SoC.

We take MT7629 as an example to demonstrate how to implement driver if
any other MediaTek chips would like to use it.
