Paul Cercueil 89a6139cd8 MIPS: JZ4780: CI20: Add pinctrl configuration for several drivers
We set the pin configuration for the jz4780-nand and jz4780-uart
drivers.

Paul Cercueil 636f8ba67f MIPS: JZ4740: Qi LB60: Add pinctrl configuration for several drivers
We set the pin configuration for the jz4740-nand, jz4740-mmc,
jz4740-fb, jz4740-pwm and jz4740-uart drivers.

This will permit those drivers to be cleaned out of the custom GPIO code
that they currently use.

Paul Cercueil 6ab5901837 MIPS: qi_lb60: Probe RTC driver from DT and use it as power controller
Since we already have a devicetree node for the jz4740-rtc driver, we
don't have to probe it from platform code.

Besides, using the jz4740-rtc driver as the power controller for the
qi_lb60 platform allows us to remove the jz4740 platform power-off code,
since this is the only jz4740-based board upstream.

Antony Pavlov 5214cae77c MIPS: devicetree: fix cpu interrupt controller node-names
Here is the quote from [1]:

    The unit-address must match the first address specified
    in the reg property of the node. If the node has no reg property,
    the @ and unit-address must be omitted and the node-name alone
    differentiates the node from other nodes at the same level

This patch adjusts MIPS dts-files and devicetree binding
documentation in accordance with [1].

Maarten ter Huurne 9d1e7875fa MIPS: JZ4740: Probe OHCI platform device via DT
The DT fragment will select the ohci-platform driver, since that can
handle the JZ4740 OHCI just fine. While I don't have a JZ4740-based
board with anything connected to the USB host controller, I did test
the generic OHCI driver successfully on a JZ4770-based board.

The device is disabled by default; boards that want to use it can
override the "status" property. The mass-production Qi LB60 boards
don't use the USB host controller.

Alex Smith 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.]

Migrate the JZ4740 & the qi_lb60 board to use common clock framework
