78800558d1 MIPS: dts: jz4780/ci20: Add NEMC, BCH and NAND device tree nodes 
Add device tree nodes for the NEMC and BCH to the JZ4780 device tree,
and make use of them in the Ci20 device tree to add a node for the
board's NAND.

Note that since the pinctrl driver is not yet upstream, this includes
neither pin configuration nor busy/write-protect GPIO pins for the
NAND. Use of the NAND relies on the boot loader to have left the pins
configured in a usable state, which should be the case when booted
from the NAND.

[ralf@linux-mips.org: fold in Geert Uytterhoeven's patch and acks from
Harvey's latest version.]

8838245d76 MIPS: JZ4740: use Ingenic SoC UART driver 
Remove the serial support from arch/mips/jz4740 & make use of the new
Ingenic SoC UART driver. This is done for both regular & early console
output.

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.

standard irqchip_init function, and make use of that function to probe
the controller by adding the appropriate node to the JZ4740 dtsi.
