Paul Burton 5b9cdd2449 MIPS: ingenic: Initial JZ4780 support
Support the Ingenic JZ4780 SoC using the existing code under
arch/mips/jz4740 now that it has been generalised sufficiently.

Paul Burton 50d893ff72 MIPS, clk: move jz4740 clock suspend, resume functions to jz4740-cgu
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.

Paul Burton ff1930c6bd MIPS,clk: migrate JZ4740 to common clock framework
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.

Paul Burton e06b86a33a MIPS: JZ4740: replace use of jz4740_clock_bdata
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.

Paul Burton 1f4b840983 MIPS: JZ4740: Call jz4740_clock_init earlier
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.

only the feature flag was not set.  Setting the one-shot flag allows the
kernel to run in tickless mode.
