2019-08-12dm: core: add support for getting register address and sizeSekhar Nori
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.

It was returning an int, which doesn't work if the u32 it is reading, or the default value, will overflow a signed int. While it could be made to work, when using a C standard/compiler where casting negative signed values to unsigned has a defined behavior, combined with careful casting, it seems obvious one is meant to use ofnode_read_s32_default() with signed values.

2019-04-23dm: core: Change platform specific translation-offset handlingStefan Roese
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.

2018-12-10bootcount: add uclass for bootcountPhilipp Tomsich
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 Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Tested-by: Klaus Goger <klaus.goger@theobroma-systems.com>

2018-11-29dm: sandbox: i2c: Add a new 'emulation parent' uclassSimon Glass
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.
