The current code is using an hard coded enum and the of node reg value of
endpoint to find out if the endpoint is mipi/hdmi/lvds/edp/dp. The order
is different between rk3288, rk3399 vop little, rk3399 vop big.
A possible solution would be to make sure that the rk3288.dtsi and
rk3399.dtsi files have "expected" reg value or an other solution is
to find the kind of endpoint by comparing the endpoint compatible value.
This patch is implementing the more flexible second solution.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private

VOP display endpoint pipeline configuration differs
between rk3288 vs rk3399.
These VOP pipeline configuration depends on how the
different display interfaces connected in sequence to
IN and OUT ports like for,
RK3288:
vopb_out: port {
#address-cells = <1>;
#size-cells = <0>;
vopb_out_edp: endpoint@0 {
reg = <0>;
remote-endpoint = <&edp_in_vopb>;
};
vopb_out_hdmi: endpoint@1 {
reg = <1>;
remote-endpoint = <&hdmi_in_vopb>;
};
vopb_out_lvds: endpoint@2 {
reg = <2>;
remote-endpoint = <&lvds_in_vopb>;
};
vopb_out_mipi: endpoint@3 {
reg = <3>;
remote-endpoint = <&mipi_in_vopb>;
};
};
RK3399:
vopb_out: port {
#address-cells = <1>;
#size-cells = <0>;
vopb_out_edp: endpoint@0 {
reg = <0>;
remote-endpoint = <&edp_in_vopb>;
};
vopb_out_mipi: endpoint@1 {
reg = <1>;
remote-endpoint = <&mipi_in_vopb>;
};
vopb_out_hdmi: endpoint@2 {
reg = <2>;
remote-endpoint = <&hdmi_in_vopb>;
};
vopb_out_mipi1: endpoint@3 {
reg = <3>;
remote-endpoint = <&mipi1_in_vopb>;
};
vopb_out_dp: endpoint@4 {
reg = <4>;
remote-endpoint = <&dp_in_vopb>;
};
};
here, HDMI interface has endpoint 1 in rk3288 and 2 in rk3399.
The rockchip vop driver often depends on this determined endpoint
number and stored in vop_mode. So based on this vop_mode the bpp
and pin polarity would configure on detected display interface.
Since, the existing driver using rk3288 vop mode settings enabling
the same will result wrong display interface configuration for rk3399.
Add the patch for fixing these vop modes for rk3399.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

This migrates rk_vop (the shared functions used by multiple VOP
mini-drivers) to be compatible with a live tree.
Unfortunately, there's
(i) a lot of tree traversal needed for a VOP (as each active VOP
vnode references back to the endpoints in the encoders and vice
versa) to configure the connection between VOPs and encoders;
(ii) the DTS binding is not too sane and one needs to walk a node's
parents (the original code just assumed that the device would
live 3 levels above the property linked through a phandle) until
a UCLASS_DISPLAY device can be found.
As part of the migration, the code for finding the enclosing display
device has been changed to not assume a specific depth of nesting
(i.e. we walk until we reach the root or find a matching device) and
to use the newly introduced (in the same series) ofnode_get_parent()
function.

To prepare for adding the RK3399 VOP driver (which shares most of its
registers and config logic with the RK3228 VOP), this change refactors
the driver and splits the RK3288-specific driver off.
The changes in detail are:
- introduces a data-structure for chip-specific drivers to register
features/callbacks with the common driver: at this time, this is
limited to a callback for setting the pin polarities (between the
VOP and the encoder modules) and a flag to signal 10bit RGB
capability
- refactors the probing of regulators into a helper function that
can take a list of regulator names to probe and autoset
- moves the priv data-structure into a (common) header file to be
used by the chip-specific drivers to provide base addresses to
the common driver
- uses a callback into the chip-specific driver to set pin polarities
(replacing the direct register accesses previously used)
- splits enabling the output (towards an encoder) into a separate
help function withint the common driver

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.
In the end we will have:
1. dev_read_addr...() - works on devices, supports flat/live tree
2. devfdt_get_addr...() - current functions, flat tree only
3. of_get_address() etc. - new functions, live tree only
All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.
Note this involves changing some dead code - the imx_lpi2c.c file.

The following changes are made to the clock API:
* The concept of "clocks" and "peripheral clocks" are unified; each clock
provider now implements a single set of clocks. This provides a simpler
conceptual interface to clients, and better aligns with device tree
clock bindings.
* Clocks are now identified with a single "struct clk", rather than
requiring clients to store the clock provider device and clock identity
values separately. For simple clock consumers, this isolates clients
from internal details of the clock API.
* clk.h is split so it only contains the client/consumer API, whereas
clk-uclass.h contains the provider API. This aligns with the recently
added reset and mailbox APIs.
* clk_ops .of_xlate(), .request(), and .free() are added so providers
can customize these operations if needed. This also aligns with the
recently added reset and mailbox APIs.
* clk_disable() is added.
* All users of the current clock APIs are updated.
* Sandbox clock tests are updated to exercise clock lookup via DT, and
clock enable/disable.
* rkclk_get_clk() is removed and replaced with standard APIs.
Buildman shows no clock-related errors for any board for which buildman
can download a toolchain.

others).
