rockchip: clk: rk3399: handle clk_enable requests for GMAC
Since commit ba1f96672522 ("net: designware: add clock support"), the
designware GMAC driver enables all referenced clocks. While this is a
no-op for the RK3399 during boot-up (reset behaviour has all the clock
gates open anyway), we still need to handle the clock-ids passed in
the enable op of the clock-driver and return a success.
This change extends the enable-op of the rk3399 clk driver to signal
success to the caller when the clocks for the GMAC are enabled.

rockchip: video: rk_vop: migrate to livetree
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.

Makefile: Don't mess with .text section location for selected arches
Most of architectures have .text section situated in the very beginning
of U-Boot binary and thus it is very logical that CONFIG_SYS_TEXT_BASE
is used on final linkage step to specify where U-Boot gets linked to.
For that we pass the following construction to the LD:
---------------------------->8-----------------------
xxx-ld ... -Ttext $(CONFIG_SYS_TEXT_BASE) ...
---------------------------->8-----------------------
But there could be exceptions. For example:
1. In case of ARCv2 we want to put vectors table in its own section
.ivt in front of .text section which means we need either add an
offset to CONFIG_SYS_TEXT_BASE to compensate for .ivt or don't
pass "-Ttext" to the LD at all and specify link base in linker
script directly.
2. Some architectures even though have .text section in the very
beginning of the U-Boot image still use different symbols to
specify link-base:
* NIOS2: CONFIG_SYS_MONITOR_BASE (which I really like because
that exactly what makes sense - where out image starts but not
beginning of its .text section which just happened to match the
whole image beginning)
* EXTENSA: CONFIG_SYS_TEXT_ADDR
* X86: Which doesn't use CONFIG_SYS_MONITOR_BASE in case of EFI
otherwise sets explicit link base in u-boot.lds
I think that's good to allow for flexibility and don't require each and
every architecture or even platform to specify CONFIG_SYS_TEXT_BASE as well
as use it to set .text section location.
So let's only pass "-Ttext xxx" for those architectures who don't set
link-base explicitly in their linker scripts.

the case of beagle-x15 where the io lines are connected to 3.3v).
Hence if "no-1-8-v" property is set, io voltage will be set to 3v.

Add a separate function for starting the clock, stopping the clock and
setting the clock. Starting the clock and stopping the clock can
be used irrespective of setting the clock (For example during iodelay
recalibration).
Also set the clock only if there is a change in frequency.

Fixes a bug found on thuban boards, which were for 2 years in
a long-term test with varying temperatures. They showed
problems in u-boot when attaching the ubi partition:
Reason is, that accidentially the U-Boot implementation
from __schedule_ubi_work() did not check the flag
ubi->thread_enabled and started with wearleveling work,
but ubi did not have setup all structures at this point
and crashes.
Solve this problem by splitting work scheduling and processing.

If actual_speed is passed as NULL in this function:
static void __twsi_i2c_init(struct mvtwsi_registers *twsi, int speed,
int slaveadd, uint *actual_speed)
than __twsi_i2c_set_bus_speed never get called. This causes i2c clock
to run on default speed - 2MHz (measured with oscilloscope). This is issue
on some boards, sunxi for example, since on I2C0 bus PMU is connected.
The bootlogs with and without the patch are as follows:
