f5b904796f dm: core: add support for getting register address and size
Current dev_read_*() API lacks support to get address and size
of a "reg" property by name or index. Add support for the same.

Livetree support has been added but not tested on real hardware.

The existing unit tests testing reading address from device-tree
have been updated to test address as well as size.

641067fb0c dm: core: Introduce xxx_translate_dma_address()
Add the following functions to translate DMA address to CPU address:
- dev_translate_dma_address()
- ofnode_translate_dma_address()
- of_translate_dma_address()
- fdt_translate_dma_address()
These functions work the same way as xxx_translate_address(), with the
difference that the translation relies on the "dma-ranges" property
instead of the "ranges" property.

Add related test. Test report:

While it could be made to work, when using a C standard/compiler where

f2100f6f77 dm: core: Change platform specific translation-offset handling
Testing has shown that the current DM implementation of a platform /
board specific translation offset, as its needed for the SPL on MVEBU
platforms is buggy. The translation offset is confingured too late,
after the driver bind functions are run. This may result in incorrect
address translations. With the current implementation its not possible
to configure the offset earlier, as the DM code has not run at all.

This patch now removed the set_/get_translation_offset() calls and
moves the translation offset into the GD variable translation_offset.
This variable will get used when CONFIG_TRANSLATION_OFFSET is enabled.
This option is enabled only for MVEBU on ARM32 platforms, where its
currenty needed and configured in the SPL.

ebb73de168 bootcount: add uclass for bootcount
The original bootcount methods do not provide an interface to DM and
rely on a static configuration for I2C devices (e.g. bus, chip-addr,
etc. are configured through defines statically).  On a modern system
that exposes multiple devices in a DTS-configurable way, this is less
than optimal and a interface to DM-based devices will be desirable.

This adds a simple driver that is DM-aware and configurable via DTS.
If ambiguous (i.e. multiple bootcount-devices are present) the
/chosen/u-boot,bootcount-device property can be used to select one
bootcount device.

Initially, this provides support for the following DM devices:
 * RTC devices

b7c25b11b6 dm: sandbox: i2c: Add a new 'emulation parent' uclass
Sandbox i2c works using emulation drivers which are currently children of
the i2c device:

	rtc_0: rtc@43 {
		reg = <0x43>;
		compatible = "sandbox-rtc";
		emul {
			compatible = "sandbox,i2c-rtc";
		};
	};

In this case the emulation device is attached to i2c bus on address 0x43
and provides the Real-Time-Clock (RTC) functionality.

However this is not ideal, since every device on an I2C bus has a child
device. This is only really the case for sandbox, but we want to avoid
special-case code for sandbox.

A better approach seems to be to add a separate node on the bus, an
'emulation parent'. This can be given a bogus address (such as 0xff) and
hides all the emulators away. Then we can use a phandle to point from the
device to the correct emualtor, and only on sandbox. The code to find an
emulator does not interfere with normal i2c operation.

Add a new UCLASS_I2C_EMUL_PARENT uclass which allows finding an emulator
given a bus, and finding a bus given an emulator. This will be used in a
follow-on patch.

25cbb47090 dm: core: Put UCLASS_SIMPLE_BUS in order
This is currently at the top in the space for internal use. But this
uclass is used outside driver model and test code. Move it into the
correct alpha order.

3abe111535 dm: core: Add a few more specific child-finding functions
Add two functions which can find a child device by uclass or by name.
The first is useful with Multi-Function-Devices (MFDs) to find one of a
particular type. The second is useful when only the name is known.

3deb1f731d spi: pl022: Simplify platdata code
pl022 spi driver support both OF_CONTROL and PLATDATA, this
patch is trying to simplify the code that differentiating
platdata vs of_control.
- Move OF_CONTROL code at one place
- Handle clock setup code directly in pl022_spi_ofdata_to_platdata
