According to the documentation [1], RX Level/Edge Configuration (trig)
and GPIO Tx/Rx Buffer Disable (bufdis) [2] settings are not applicable
in native mode and BIOS does not need to configure them. Therefore,
there is no need to configure this in gpio.h using PAD_CFG_NF_BUF_TRIG
macros. Use PAD_CFG_NF instead and set this fields to 0.

When refactoring, one can move code around quite a bit while preserving
reproducibility, unless there is an assert-style macro somewhere... As
these macros use __FILE__ and __LINE__, just moving them is enough to
change the resulting binary, making timeless builds rather useless.
To improve reproducibility, do not use __FILE__ nor __LINE__ inside the
assert-style macros. Instead, use hardcoded values. Plus, mention that
timeless builds lack such information in place of the file name, so that
grepping for the printed string directs one towards this commit. And for
the immutable line number, we can use 404: line number not found :-)

1. Populate SMBIOS data from OCP_DMI driver read from FRU
2. Set the read PPIN MSR for CPU0 and CPU1 to BMC, selecting
PARALLEL_MP_AP_WORK to enable OCP DMI driver to read remote socket PPIN.
Tested on OCP Tioga Pass.

The Raydium ACPI entry currently provides a reset GPIO and an _ON/_OFF
method to the kernel. These are contradictory. The ownership of the GPIO
should be mutually exclusive between either the OS or the FW. Since we
have two methods exposed this causes the OS to reset the TS twice. Once
using the _ON method, and once using the GPIO. Additionally the _ON
method is waiting for 20ms after reset while the OS driver uses a 50ms
delay. The Raydium TS datasheet specifies 20ms for FW ready time, so the
OS driver is adding additional padding.
The reference design has a 32ms rise time on the reset line. So without
this patch, the OS tries to reset the TS using the _ON method and it
waits for 20ms. This is not enough time for the reset line to reach
high, let alone account for the FW ready time. The OS driver then tries
to reset the device by toggling the GPIO. It waits 50ms which is still
2ms less than required.
This CL removes the GPIO from being exported in the _CRS so the OS
driver won't try and reset the device. It also increases the reset delay
by 32ms to account for the rise time.
This isn't a complete fix. I think that the slow rise time is causing
some kind of metastability in the TS reset hardware. Using a script to
bind and unbind the TS driver, the TS device becomes unresponsive after
~200 iterations. The only way to reset the device is to power cycle.
The TS power is also not currently controlled by the power resource.
This means that we have no guarantee over when the reset line is
toggled. This will lead to issues while spending and resuming.

Earlier versions of Dalboz did not correctly handle HS400. One fix was
to add stitching vias, but these boards did not have them. b/156539551
Another possible fix is to add tuning parameters including drive
strength, but that is still a WIP. b/158959725
This should correct OS load failures in the meantime by running the bus
slower.
