[PATCH v4 0/7] clk: Add common clock support for Mediatek MT8135 and MT8173.

[Henry Chen]

This patchset contains the initial common clock support for Mediatek SoCs.
Mediatek SoC's clock architecture comprises of various PLLs, dividers, muxes and clock gates.

This patchset also contains a basic clock support for Mediatek MT8135 and MT8173.

This driver is based on 3.19-rc1 + MT8135 and MT8173 basic support.

Changes in v2:
- Re-ordered patchset. Fold include/dt-bindings and DT document in 1st patch.

Changes in v3:
- Rebase to 3.19-rc1.
- Refine code. Remove unneed functions, debug logs and comments, and fine tune error logs.

Changes in v4:
- Support MT8173 platform.
- Re-ordered patchset. driver/clk/Makefile in 2nd patch.
- Extract the common part definition(mtk_gate/mtk_pll/mtk_mux) from clk-mt8135.c/clk-mt8173.c to clk-mtk.c.
- Refine code. Rmove unnessacary debug information and unsed defines, add prefix "mtk_" for static functions.
- Remove flag CLK_IGNORE_UNUSED and set flag CLK_SET_RATE_PARENT on gate/mux/fixed-factor.
- Use spin_lock_irqsave(&clk_ops_lock, flags) instead of mtk_clk_lock.
- Example above include a node for the clock controller itself, followed by the i2c controller example above.
