[PATCH v7 0/9] Fixes and new clocks support for Mediatek MT8173

From: James Liao
Date: Mon Aug 10 2015 - 05:50:59 EST

This patchset is based on 4.2-rc2 and [1], and contains minor fixes and
subsystem clocks support for Mediatek MT8173.

The previous reviews can be found in [2].

changes since v6:
- Use DUMMY_RATE (0) instead of typical rate for clocks that we don't care
and not controlled in CCF.

changes since v5:
- Rebase to 4.2-rc2.
- Patch "Fix enabling of critical clocks" had been included in 4.2-rc2,
so it need not be included in this patchset.

changes since v4:
- Add a separated patch to remove unused dpi_ck.
- Add separated patches to fix clk/mediatek in release 4.2-rc1.
- Add __init* for initialization data and functions.
- Rename dummy_clk with oscillator in DT.
- Remove mtk_clk_register_apmixed_ex(), call mtk_clk_register_ref2usb_tx()
directly to register USB clock.

changes since v3:
- Remove clk_null dependency from root clocks.
- Use fixed-rate clocks with typical rate to replace clk_null.
- Separate ref2usb_tx implementation to clk-apmixed.c
- Use clock-controller as the name of clock providers.

changes since v2:
- Rebase to 4.2-rc1.
- Add device tree nodes for subsystem clocks.
- Fine tune comments of patches.
- Add __init, __initconst and const to init data and functions.
- Removed unused code from init functions of subsystem clocks.

changes since v1:
- Add CA7PLL and CA15PLL as critical clocks.
- Use the same register descriptor for imgsys, vensys and vencltsys.
- Generalize apmixedsys special clocks registration.
