2015-09-03MIPS: jz4740: Migrate to new 'set-state' interfaceViresh Kumar1-19/+27
Migrate jz4740 driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now. This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED.

Support the Ingenic JZ4780 SoC using the existing code under arch/mips/jz4740 now that it has been generalised sufficiently.

2015-06-21MIPS, clk: move jz4740 clock suspend, resume functions to jz4740-cguPaul Burton1-1/+0
The jz4740-cgu driver already has access to the CGU, so it makes sense to move the few remaining accesses to the CGU from arch/mips/jz4740 there too. Move the jz4740_clock_{suspend,resume} functions there for such consistency. The arch/mips/jz4740/clock.c file now contains nothing more of use & so is removed.

2015-06-21MIPS,clk: migrate JZ4740 to common clock frameworkPaul Burton1-0/+2
Migrate the JZ4740 & the qi_lb60 board to use common clock framework via the new Ingenic SoC CGU driver. Note that the JZ4740-specific debugfs code is removed since common clock framework provides its own debug capabilities.

2015-06-21MIPS: JZ4740: replace use of jz4740_clock_bdataPaul Burton1-1/+8
Replace uses of the jz4740_clock_bdata struct with calls to clk_get_rate for the appropriate clock. This is in preparation for migrating the clocks towards common clock framework & devicetree.

2015-06-21MIPS: JZ4740: Call jz4740_clock_init earlierPaul Burton1-0/+2
Call jz4740_clock_init before any uses of jz4740_clock_bdata occur. This is in preparation for replacing uses of that struct with calls to clk_get_rate, which will allow the clocks to be migrated towards common clock framework & devicetree.

The code for supporting one-shot mode for the clockevent is already there, only the feature flag was not set. Setting the one-shot flag allows the kernel to run in tickless mode.
