It was noticed that unbinding and rebinding the KSZ8851 ethernet
resulted in the driver reporting "failed to read device ID" at probe.
Probing the reset line with a 'scope while repeatedly attempting to
bind the driver in a shell loop revealed that the KSZ8851 RSTN pin is
constantly held at zero, meaning the device is held in reset, and
does not respond on the SPI bus.

Experimentation with the startup delay on the regulator set to 50ms
shows that the reset is positively released after 20ms.

Schematics for this board are not available, and the traces are buried
in the inner layers of the board which makes tracing where the RSTN pin
extremely difficult.  We can only guess that the RSTN pin is wired to a
reset generator chip driven off the ethernet supply, which fits the
observed behaviour.

Include this delay in the regulator startup delay - effectively
treating the reset as a "supply stable" indicator.

This can not be modelled as a delay in the KSZ8851 driver since the
reset generation is board specific - if the RSTN pin had been wired to
a GPIO, reset could be released earlier via the already provided support
in the KSZ8851 driver.

This also got confirmed by Peter Ujfalusi <peter.ujfalusi@ti.com> based
on Blaze schematics that should be very close to SDP4430:

TPS22902YFPR is used as the regulator switch (gpio48 controlled):
Convert arm boot_lock to raw The VOUT is routed to TPS3808G01DBV.
(SCH Note: Threshold set at 90%. Vsense: 0.405V).

According to the TPS3808 data sheet the RESET delay time when Ct is
open (this is the case in the schema): MIN/TYP/MAX: 12/20/28 ms.

When a micro SD card is inserted in the PDU001 card cage, the card
detection switch is opened and the corresponding GPIO input is driven
by a pull-up. Hence change the active level of the card detection
input from low to high.

      ARM: OMAP1: ams-delta: Fix audio permanently muted · 2afdb4c4
      Janusz Krzysztofik authored 
      Since commit 1137ceee ("ARM: OMAP1: ams-delta: Don't request unused
GPIOs"), on-board audio has appeared muted.  Believed to be unused GPIO
pin "hookflash1", apparently set high regardless of the corresponding
bit of "latch2" port attempted to be set low during .init_machine(),
has been identified as the reason.

According to Amstrad E3 wiki, the purpose of the pin hasn't been
clearly identified.  Original Amstrad software used to produce a high
pulse on it when the phone was taken off hook or recall was pressed.
With the current finding, we can assume the pin provides a kind of
audio mute function.

Proper resolution of the issue should be done in two steps:
- resolution of an issue with the pin state not reflecting the value
  the corresponding bit of the port was attempted to be initialized
  with,
- extension of on-board audio driver with a new control.

For now, rename the pin to "audio_mute" to reflect its function and,
as a quick fix, hogg it as output low so on-board audio can produce
audible sound again.

      OMAP5's Super-Speed USB port has a software mailbox register
that needs to be fed with VBUS and ID events from an external
VBUS/ID comparator.

Without this, Host role will not work correctly.
