This commit introduces the clocks found in the Allwinner A33 CCU. Since this SoC is very similar to the A23, and we share a significant share of the DTSI, the clock IDs that are going to be used will also be shared with the A23, hence the name of the various header files. Signed-off-by:

Some dividers might have a maximum value that is lower than the width of the register. Add a field to _ccu_div to handle those case properly. If the field is set to 0, the code will assume that the maximum value is the maximum one that can be used with the field register width. Otherwise, we'll use whatever value has been set.

Most of the sun8i q8 boards have an SDIO wifi controller, on the variants which use an USB wifi controller, this will result in a couple of error msg-s in dmesg when proving the sdio bus and an used mmc controller. The best way to deal with wifi on this boards really is to simply let the kernel auto-detect usb or sdio wifi controllers, so we will just have to live with the few errors in dmesg. This has been tested on a23 based q8 tablets with ESP8089, RTL8703AS and RTL8189FTV wifi controllers. Signed-off-by:

The Orange Pi Plus2E is an extended version of the Orange Pi Pc Plus, with 2G RAM and an external gbit ethernet phy. Note currently the dts is pretty much empty (except for including the pc-plus dts), I've a local patch which enables the emac actually making this dts different from the pc-plus one, but that needs the h3 emac driver to get merged first.

Update the sun8i-h3-orangepi-plus.dts model string to reflect that it is valid for both the Orange Pi Plus and the Orange Pi Plus 2. This is also meant to help users realize that it is not valid for the new Orange Pi Plus 2E, which will get its own dts. Signed-off-by:

The inet-d978_rev2 is a pcb used in generic A33 based tablets. It features volume buttons, micro-usb otg, headphone connector and a power button. On the board a Realtek RTL8723BS SDIO Wi-Fi module are soldered, and there is also a accompanied board which has a Goodix GT9271 soldered. As this board is desired to create tablets with a Home key dealed by GT9271, a LED is present at the front panel at the position of the Home key. Signed-off-by:

Rename the reference-design-tablet touchscreen node from gsl1680 to touchscreen, all? tablets seem to use the same power and interrupt gpio-s, but not all tablets use a gsl1680 controller making the gsl1680 name somewhat misleading. Also move the reg and compatible property to the actual tablet dts as they may differ per tablet. Signed-off-by:

Add a dts file for the Empire Electronix M712 tablet, this is a 7" A13 tablet, with micro-usb (otg), headphone and micro-sd slots on the outside. It uses a Goodix gt811 touchscreen controller, a RTL8188CTV wifi chip and a DMART06 (1238a4) accelerometer. Note currently the dts for this is somewhat empty. This will change once we add support for the touchscreen and accelerometer. Signed-off-by:

A23/A33 has a NAND controller which can now be used properly. Add a device node for it. The DMA function cannot work because of changed DMA IP block, so it's temporarily removed in the device node. However, with PIO mode it can still work. Tested on an Aoson M751s tablet with Boris Brezillon's "mtd: nand: allow vendor specific detection/initialization" patchset, which is needed for the large-block MLC chip to be recognized correctly.

On sunxi we support cpufreq by changing the clock rate of PLL-CPU. It's possible the clock output of the PLL goes out of the CPU's operational limits when the PLL's multipliers / dividers are changed and it hasn't stabilized yet. This would result in the CPU hanging. To circumvent this, we temporarily switch the CPU mux clock to another stable clock before the rate change, and switch it back after the PLL stabilizes. This is done with clk notifiers registered on the PLL. This patch adds common functions for notifiers to reparent mux clocks. Signed-off-by:
