[PATCH 1/5] clk: ingenic: Add missing header in cgu.h

[PATCH 1/5] clk: ingenic: Add missing header in cgu.h

[Paul Cercueil]

The cgu.h has structures that contain 'clk_onecell_data' and 'clk_hw'
structures (no pointers), so the <linux/clk-provider.h> header should be
included.

[PATCH 2/5] clk: ingenic: Handle setting the Low-Power Mode bit

[Paul Cercueil]

The Low-Power Mode, when enabled, will make the "wait" MIPS instruction
suspend the system.

This is not really clock-related, but this bit happens to be in the
register set of the CGU.

[PATCH 3/5] MIPS: jz4740: PM: Let CGU driver suspend clocks and set sleep mode

[Paul Cercueil]

Instead of forcing the jz4740 clocks to suspend here, we let the CGU
driver handle it.
We also let the CGU driver set the "sleep mode" bit.

This has the added benefit that now it is possible to build a kernel on
SoCs newer than the JZ4740 with CONFIG_PM.
