This commit adds spi driver quad io support for AST2600
Note:- Removed n25q00 Quad I/O support for the time being due to clock issue
with chip 'Micron 8UA15 - rw182 (128MB)' while enabling Quad I/O mode.

Tested:
1. Config baud rate to 921600 in BIOS setup page
2. BMC could change env variable "hostserialcfg" to 1.
3. BMC is force to reboot and SPA baud rate is changed to 921600 successfully.
4. It is same for back to 115200.

Since we enabled I2C busses in u-boot, we need to disable the I2C
bus and clear all garbage interrupts when kernel probes the bus.
This commit refines the initialization flow by adding a bus reset
at the beginning of probe function and by moving bus init function
after interrupt handling setup.

Introduces new attribute to Mass Storage Gadget ConfigFS : stats.
It's read-only attribute which contains statistics of read/write operations
based on LUN transaction counters (IO number and bytes transferred).
Goal is to provide a way to observe whether simulated device is actually
used by host. Statistics on hosted file / nbd level are not always viable
due to page cache having severe impact on actual IO statistics.
This attribute should provide information about host IO on USB Gadget as
close to endpoint as possible.
Attribute is tied completely to configFS implementation and it's lifecycle
is managed by Kernel and user. Driver implements a handler which populates
output buffer on read.
Tests performed:
- mounted USB Mass Storage gadget, new attribute showed up in gadget tree
- attribute was monitored for changes during IO performed on host machine
- removed device, attribute (along with other device attributes) was gone

This commit adds DMA mode transfer support.
Only AST2500 supports DMA mode under some limitations:
I2C is sharing the DMA H/W with UHCI host controller and MCTP
controller. Since those controllers operate with DMA mode only, I2C
has to use buffer mode or byte mode instead if one of those
controllers is enabled. Also make sure that if SD/eMMC or Port80
snoop uses DMA mode instead of PIO or FIFO respectively, I2C can't
use DMA mode.

Byte mode currently this driver uses makes lots of interrupt call
which isn't good for performance and it makes the driver very
timing sensitive. To improve performance of the driver, this commit
adds buffer mode transfer support which uses I2C SRAM buffer
instead of using a single byte buffer.
AST2400:
It has 2 KBytes (256 Bytes x 8 pages) of I2C SRAM buffer pool from
0x1e78a800 to 0x1e78afff that can be used for all busses with
buffer pool manipulation. To simplify implementation for supporting
both AST2400 and AST2500, it assigns each 128 Bytes per bus without
using buffer pool manipulation so total 1792 Bytes of I2C SRAM
buffer will be used.
AST2500:
It has 16 Bytes of individual I2C SRAM buffer per each bus and its
range is from 0x1e78a200 to 0x1e78a2df, so it doesn't have 'buffer
page selection' bit field in the Function control register, and
neither 'base address pointer' bit field in the Pool buffer control
register it has. To simplify implementation for supporting both
AST2400 and AST2500, it writes zeros on those register bit fields
but it's okay because it does nothing in AST2500.
It provides buffer based master and slave data transfer.

HID events can be sent even when the host disconnects the HID
device according to the current graphic mode. For an example, if
KVM mouse events are sent when the host is in text mode, queueing
of end point messages will be dropped with this message:
configfs-gadget gadget: usb_ep_queue error on int endpoint -108
This case is very usual case in BMC since BMC can control power
status of the host, so this commit suppress the error printing outs
with making HID gadget driver drop events quietly in the case.
This should be a downstream only customization. Do not upstream it.

If LPC KCS driver is registered ahead of lpc-ctrl module, LPC KCS
block will be enabled without heart beating of LCLK until lpc-ctrl
enables the LCLK. This issue causes improper handling on host
interrupts when the host sends interrupt in that time frame. Then
kernel eventually forcibly disables the interrupt with dumping
stack and printing a 'nobody cared this irq' message out.
To prevent this issue, all LPC sub-nodes should enable LCLK
individually so this patch adds clock control logic into the LPC
KCS driver.

BMC uses I2C bus 7 as a PMBus channel to communicate with PSUs,
also ME uses this bus as SMLink to control PSUs so this bus is
managed by multi-masters. In this use case, some arbitration errors
are expected so we need to add retry logic. And PMBus subsystem
uses I2C bus in kernel internally so retry logic should be
supported in kernel level.
To support the use case, this commit adds 'bus-timeout-ms' and
'#retries' device tree properties to set the bus specific
parameters at kernel boot time without using any additional ioctls
from user space.
This patch would not be accepted by I2C maintainer in linux
upstream because he doesn't like adding these legacy properties
into device tree, so keep it only in downstream.

This commit adds mux hold/unhold message types to support extended
mux control for IPMB and MCTP devices. A hold or an unhold message
can be added at the end of I2C message stream wrapped by
repeated-start, also can be used as a single message independantly.
This mux hold/unhold message will be delivered throughout all mux
levels in the path. Means that if it goes to multi-level mux path,
all muxes will be held/unheld by this message.
1. Hold message
struct i2c_msg msg;
uint16_t timeout = 5000; // timeout in ms. 5 secs in this example.
msg.addr = 0x0; // any value can be used. addr will be ignored in this packet.
msg.flags = I2C_M_HOLD; // set this flag to indicate it's a hold message.
msg.len = sizeof(uint16_t); // timeout value will be delivered using two bytes buffer.
msg.buf = (uint8_t *)&timeout; // set timeout value.
2. Unhold message
struct i2c_msg msg;
uint16_t timeout = 0; // set 0 for an unhold message.
msg.addr = 0x0; // any value can be used. addr will be ignored in this packet.
msg.flags = I2C_M_HOLD; // set this flag to indicate it's an unhold message.
msg.len = sizeof(uint16_t); // timeout value will be delivered using two bytes buffer.
msg.buf = (uint8_t *)&timeout; // set timeout value.
This unhold message can be delivered to a mux adapter even when
a bus is locked so that any holding state can be unheld
immediately by invoking this unhold message.
This patch would not be welcomed from upstream so it should be kept
in downstream only.

The pass-through input GPIOs cannot be monitored because when
requested, pass-through is disabled which causes a change on the
pass-through output.
The SIO GPIOs cannot be monitored because when requested, the
request is rejected based on the value of the ACPI strap.
This change removes the register check condition from the pass-
through and desired SIO GPIOs so they can be requsted and
monitored from power control.
Tested:
For pass-through, I used gpioset to hold a request on the input
GPIOs and confirmed that pass-through remained enabled.
For SIO, I used gpioget to confirm that I can successfully request
and read the GPIO value.
