Some watchdog devices, e.g. external gpio-triggered ones, must be
reset more often than once per second, which means that the current
rate-limiting logic in watchdog_reset() fails to keep the board alive.
gpio-wdt.txt in the linux source tree defines a "hw_margin_ms"
property used to specifiy the maximum time allowed between resetting
the device. Allow any watchdog device to specify such a property, and
then use a reset period of one quarter of that. We keep the current
default of resetting once every 1000ms.

This function is a bit large for an inline function, and for U-Boot
proper, it is called via a function pointer anyway (in board_r.c), so
cannot be inlined.
It will shortly set a global variable to be used by the
watchdog_reset() function in wdt-uclass.c, so this also allows making
that variable local to wdt-uclass.c.
The WATCHDOG_TIMEOUT_SECS define is not used elsewhere.

Rather than keeping the asynchronous schedule running always, keep it
running only across USB mass storage transfers for now, as it seems
that keeping it running all the time interferes with certain control
transfers during device enumeration.
Note that running the async schedule all the time should not be an
issue, especially on EHCI HCD, as that one implements most of the
transfers using async schedule.
Note that we have usb_disable_asynch(), which however is utterly broken.
The usb_disable_asynch() blocks the USB core from doing async transfers
by setting a global flag. The async schedule should however be disabled
per USB controller. Moreover, setting a global flag does not prevent the
controller from using the async schedule, which e.g. the EHCI HCD does.
This patch implements additional callback to the controller, which
permits it to lock the async schedule and keep it running across
multiple transfers. Once the schedule is unlocked, it must also be
disabled. This thus prevents the async schedule from running outside
of the USB mass storage transfers.

The commit a673025535ae ("serial: zynq: Initialize uart only before
relocation") introduced code which detects relocation which is working for
single uart instance. With multiple instances in place there is a need to
enable and setup every instance. That's why detect if TX is enabled. If it
is then don't initialize uart again.
In post probe setbrg is called to setup baudrate but values should be the
same.
As a side effect of this change is that DECLARE_GLOBAL_DATA_PTR can be

Add cache flush to zynq_gem_free_pkt. This is necessary
because some net routines would modify this buffer in place.
The cache_invalidate in the zynq_gem_recv function would cause
the modifications to the buffer to overwrite the DMA from the GEM,
if cache coherency is not enabled in the GEM, the next time the
buffer is in use.
Flushing the cache when the buffer is no longer in use by the
net functions ensures that the GEM DMA is going to take place
into a clean buffer.

Until now, the mmc clock was left in a good enough state by the ROM
code to be used by the controller. However on some SoC, if the ROM
code finds a bootloader on USB or SPI, it might leave the MMC clock

Enable the input clocks provided to the mmc controller. While the
u-boot mmc controller driver is not doing fancy settings like the Linux,
it at least needs to make these clocks are running.

This commit (82de42fa14682d408da935adfb0f935354c5008f) calls child's
ofdata_to_platdata() method before the parent is probed in dm core.
This has caused the driver no longer able to get the correct parent
clock's register base in the ofdata_to_platdata() method because the
parent clocks will only be probed after the child's ofdata_to_platdata().
To resolve this, the clock parent's register base will only be retrieved
by the child in probe() method instead of ofdata_to_platdata().

- Fix a regression of ns16550 serial driver that breaks Intel Edison

Currently the driver gets ns16550 base address in the driver
probe() routine, which may potentially break any ns16550 wrapper
driver that does additional initialization before calling
ns16550_serial_probe().
Things are complicated that we need consider ns16550 devices on
both simple-bus and PCI bus. To fix the issue we move the base
address assignment for simple-bus ns16550 device back to the
ofdata_to_platdata(), and assign base address for PCI ns16550
device in ns16550_serial_probe().
This is still not perfect. If any PCI bus based ns16550 wrapper
driver tries to access plat->base before calling probe(), it is
still subject to break.

When claim_bus was setting the clock, it reset the QSPI controller,
which wipes out any tap delays set by previous bootloaders (nvtboot,
CBoot for example on Nano). Instead of doing that in claim_bus, which
gets called a lot, moved clock setting to probe(), and set tap delays
there, too. Also updated clock to 80MHz to match CBoot. Now QSPI env
save works reliably again.

claim_bus() is passed a udevice *dev, which is the bus device's parent.
In this driver, claim_bus assumed it was the bus, which caused the
'priv' info pointer to be wrong, and periph_id was incorrect. This in
turn caused the periph clock call to assign the wrong clock (PLLM
instead of PLLP0), which caused a kernel warning. I only saw the 'bad'
periph_id when enabling DEBUG due to an assert. Not sure how QSPI was
working w/this errant clock, but it was moot as QSPI wasn't active
unless you probed it, and that wasn't happening until I posted a patch
to enable env save to QSPI for Nano (coming soon).

According to the HW team, for some reason the normal clock select code
picks what appears to be a perfectly valid 375KHz SD card clock, based
on the CAR clock source and SDMMC1 controller register settings (CAR =
408MHz PLLP0 divided by 68 for 6MHz, then a SD Clock Control register
divisor of 16 = 375KHz). But the resulting SD card clock, as measured by
the HW team, is 700KHz, which is out-of-spec. So the WAR is to use the
values given in the TRM PLLP table to generate a 400KHz SD-clock (CAR
clock of 24.7MHz, SD Clock Control divisor of 62) only for SDMMC1 on
T210 when the requested clock is <= 400KHz. Note that as far as I can
tell, the other requests for clocks in the Tegra MMC driver result in
valid SD clocks.

As per the T210 TRM, when running at 3.3v, the SDMMC1 tap/trim and
autocal values need to be set to condition the signals correctly before
talking to the SD-card. This is the same as what's being done in CBoot,
but it gets reset when the SDMMC1 HW is soft-reset during SD driver
init, so needs to be repeated here. Also set autocal and tap/trim for
SDMMC3, although no T210 boards use it for SD-card at this time.

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.
