This patch extends pmic_bind_children prefix matching. In addition to
the node name the property regulator-name is used while trying to match
prefixes. This allows assigning different drivers to regulator nodes
named regulator@1 and regulator@10 for example.
I have discarded the idea of using other properties then regulator-name
as I do not see any benefit in using property compatible or even
regulator-compatible. Of course I am open to change this if there are
good reasons to do so.

controllers and peripherals within the SoC.
Each clock has assigned identifier and client device tree nodes can use
this identifier to specify the clock which they consume. All available
clocks are defined as preprocessor macros in the

The reset circuitry in the RK3399 only resets 'almost all logic' when
a software reset is performed. To make our software maintenance
easier in the future, we want to have the option (controlled by a DTS
property) to force all reset causes other than a power-on reset to
trigger a power-on reset via a GPIO trigger.
This adds the necessary support to the rk3399-puma (i.e. RK3399-Q7)
board-support and the documentation for the new property
(sysreset-gpio) within the /config-node.

The regulator bindings state that regulator prefixes are allowd to be
in upper or lower case. However pmic_bind_children from pmic_uclass uses
strncmp to compare DT node name against prefix. This comparison is case
sensitive hence the regulator driver prefix case matters.

It is often desirable to configure the spl-boot-order (i.e. the order
that SPL probes devices to find the FIT image containing a full U-Boot)
such that it contains 'the same device the SPL stage was booted from'
early on. To support this, we introduce the 'same-as-spl' specifier
for the spl-boot-order property.
This commit adds:
- documentation for the new board_spl_was_booted_from() function that
individual SoCs/boards should provide, if they can determine where
the SPL was booted from
- implements the new board_spl_was_booted_from() stub function
- adds support for handling the 'same-as-spl' specifier and calling
into the per-SoC/per-board support code.
This also updates the documentation for the 'u-boot,spl-boot-order'
property.

This adds a DRAM controller driver for the RK3368 and places it in
drivers/ram/rockchip (where the other DM-enabled DRAM controller
drivers for rockchip devices should also be moved eventually).
At this stage, only the following feature-set is supported:
- DDR3
- 32-bit configuration (i.e. fully populated)
- dual-rank (i.e. no auto-detection of ranks)
- DDR3-1600K speed-bin
This driver expects to run from a TPL stage that will later return to
the RK3368 BROM. It communicates with later stages through the
os_reg2 in the pmugrf (i.e. using the same mechanism as Rockchip's DDR
init code).
Unlike other DMC drivers for RK32xx and RK33xx parts, the required
timings are calculated within the driver based on a target frequency
and a DDR3 speed-bin (only the DDR3-1600K speed-bin is support at this
time).
The RK3368 also has the DDRC0_CON0 (DDR ch. 0, control-register 0)
register for controlling the operation of its (single-channel) DRAM
controller in the GRF block. This provides for selecting DDR3, mobile
DDR modes, and control low-power operation.
As part of this change, DDRC0_CON0 is also added to the GRF structure
definition (at offset 0x600).

The RK3399 does not have any boot selection pins and the BootROM probes
the boot interfaces using the following boot-order:
1. SPI
2. eMMC (sdhci in DTS)
3. SD card (sdmmc in DTS)
4. USB loader
For ease of deployment, the SPL stage should mirror the boot order of
the ROM and use the same probing order (assuming that valid images can
be detected by SPL) unless instructed otherwise. The boot-order can
then be configured via the 'u-boot,spl-boot-order' property in the
chosen-node of the DTS.
While this approach is easily extensible to other boards, it is only
implemented for the RK3399 for now, as the large SRAM on the RK3399
makes this easy to fit the needed infrastructure into SPL and our
production setup already runs with DM, OF_CONTROL and BLK in SPL.
The new boot-order property is expected to be used in conjunction with
FIT images (and all legacy image formats disabled via Kconfig).
A boot-sequence with probing and fallthroughs from SPI via eMMC to SD
card (i.e. &spiflash, &sdhci, &sdmmc) has been validated on the RK3399-Q7.

This patch adds support for having a "fixed-link" to some other MAC
(like some embedded switch-device).
For this purpose we introduce a new phy-driver, called "Fixed PHY".
Fixed PHY works only with CONFIG_DM_ETH enabled, since the fixed-link is
described with a subnode below ethernet interface.
Most ethernet drivers (unfortunately not all are following same scheme
for searching/attaching phys) are calling "phy_connect(...)" for getting
a phy-device.
At this point we link in, we search here for a subnode called "fixed-
link", once found we start phy_device_create(...) with the special phy-
id PHY_FIXED_ID (0xa5a55a5a).
During init the "Fixed PHY" driver has registered with this id and now
gets probed, during probe we get all the details about fixed-link out of
dts, later on the phy reports this values.
