When IP is configured with pong buffers, IP is receiving packets to ping

Signed-off-by: Michal Simek <michal.simek@xilinx.com>
The original logic in the driver was exchanging buffers which are used for
sending packet and tx_ping and tx_pong buffers were exchanged all the
time to ensure that IP has enough time to send the packet out.
Based on this "feature" send function was using nextbuffertouse variable
to save which buffer should be used.
Before this algorithm was called driver checked that there is free
buffer available.
This checking remains in the driver but driver tries to use tx_ping
first if available. If not, tx_pong buffer is used instead.
To reach this code the original condition is met that at least one of the
buffer should be available.

At present this SPI driver works by searching the PCI buses for its

In addition the driver has code to determine the type of Intel PCH that is
used (version 7 or version 9). Now that we have proper PCH drivers we can
use those to obtain the information we need.
While the device tree has a node for the SPI peripheral it is not in the
right place. It should be on the PCI bus as a sub-peripheral of the LPC
device.
Update the device tree files to show the SPI controller within the PCH, so
that PCI access works as expected.

As there are no handshakes for INTERRUPT SSPLITs the SSPLIT may have

In contrast to non-SPLIT transfers each transaction has to be submitted
as an individual chunk.
The transaction state machine proceeds from SSPLIT to CSPLIT if the ACK
flag is set. CSPLIT has to be repeated while NYET is set.

A transfer is completed if the XFERCOMP flag is set, irrespective of the
ACK flag. BULK OUT transfers to some HS devices complete without having
the ACK flag set, which signal the devices has responded with an NYET
to the transfer (PING protocol).
The new behaviour matches the Linux kernel minus any PING protocol.

Fix two errors in transfer len calculation, move loop invariant code out
of loop.
If xfer_len is equal to CONFIG_DWC2_MAX_TRANSFER_SIZE (or slightly
smaller), the xfer_len will be to large, e.g.:
xfer_len = MAX_TRANSFER_SIZE = 65535
max packet size = 512
=> num_packets = 128
=> IN xfer_len = 65536
For OUT transactions larger than (65536 - mps) bytes, the xfer_len
determination is quite awkward, it is only correct due to:
- max_packet_size for control/bulk/interrupt is required to be
power-of-two.
- (CONFIG_DWC2_MAX_TRANSFER_SIZE + 1) % max-packet-size is zero
for all allowed (2^3 ... 2^9) packet sizes
As the max xfer len is loop invariant, it can be moved out of the loop.

Some Rockchip SoCs support HDMI output. Add a display driver for this so
that these displays can be used on supported boards.
Unfortunately this driver is not fully functional. It cannot reliably read
EDID information over HDMI. This seems to be due to the clocks being
incorrect - the I2C bus speed appears to be up to 100x slower than the
clock settings indicate. The root cause may be in the clock logic.

The current DisplayPort uclass is too specific. The operations it provides
are shared with other types of output devices, such as HDMI and LVDS LCD

display_timing internally.
Also update nyan-big which is affected by this.

We must use the console name in the 'stdout' variable to select the one

'vidconsole1' for the second, etc.

The current method assumes that clocks are numbered from 0 and we can
determine a clock by its number. It is safer to use an ID in the clock's

GPIO drivers want to be able to show if a pin is enabled for input, output,
or is being used by another function. Some drivers can easily find this
and the code is included in the driver. For some SoCs this is more complex.
Conceptually this should be handled by pinctrl rather than GPIO. Most
pinctrl drivers will have this feature anyway.
Add a method by which a GPIO driver can obtain the pin mux value given a
GPIO reference. This avoids repeating the code in two places.
