The current implementation of dmi_name_in_vendors() is an invitation to
lazy coding and false positives [1]. Searching for a string in 8 know
what you're looking for, so you should know where to look. strstr isn't
fast, especially when it fails, so we should avoid calling it when it
just can't succeed.
Looking at the current users of the function, it seems clear to me that
they are looking for a system or board vendor name, so let's limit
dmi_name_in_vendors to these two DMI fields. This much better matches
the function name, BTW.
[1] We currently have code looking for short names in DMI data, such as
"IBM", "ASUS" or "Acer". I let you guess what will happen the day other
vendors ship products named, for example, "SCHREIBMEISTER", "PEGASUS" or
"Acerola".

The driver for the DigsyMTC display configuration EEPROMs device got
added by commit 469dded183 ("misc/eeprom: add eeprom access driver for
digsy_mtc board"). Its Kconfig symbol depends on PPC_MPC5200_GPIO. But
at the time that driver got added PPC_MPC5200_GPIO was already renamed
to GPIO_MPC5200, by commit 6eae1ace68 ("gpio: Move mpc5200 gpio driver
to drivers/gpio").
So make this driver depend on GPIO_MPC5200. And since GPIO_MPC5200
itself implies that GPIOLIB is set, that dependency can be dropped.

- Set the state to TASK_INTERRUPTIBLE using __set_current_state()
instead of set_current_state() as the spin_unlock is an implicit memory
barrier.
- After return from schedule(), there is no need to set the current
state to TASK_RUNNING - a call to schedule() always returns in
TASK_RUNNING state.

There may be an issue when the user issue "reboot/shutdown" command, then
the device has shut down its hardware, after that, this runtime-pm featured
device's driver will probably be scheduled to do its suspend routine,
and at its suspend routine, it may access hardware, but the device has
already shutdown physically, then the system hang may be occurred.
I ran out this issue using an auto-suspend supported USB devices, like
3G modem, keyboard. The usb runtime suspend routine may be scheduled
after the usb controller has been shut down, and the usb runtime suspend
routine will try to suspend its roothub(controller), it will access
register, then the system hang occurs as the controller is shutdown.

The crisv10.c and the atmel_serial.c serial drivers intepret the fields of the
serial_rs485 structure in a different way.
In particular, crisv10.c uses SER_RS485_RTS_AFTER_SEND and
SER_RS485_RTS_ON_SEND for the voltage of the RTS pin; atmel_serial.c,
instead, uses these values to know if a delay must be set before and
after sending. This patch makes the usage of these variables consistent
across all drivers and fixes the Documentation as well.
From now on, SER_RS485_RTS_AFTER_SEND and SER_RS485_RTS_ON_SEND will be
used to set the voltage of the RTS pin (as in the crisv10.c driver); the
delay will be understood by looking only at the value of
delay_rts_before_send and delay_rts_after_send.

Changing UART mode PIO->DMA->PIO->DMA like below, pch_uart driver can't get
DMA channel resource.
setserial /dev/ttyPCH0 ^low_latency
setserial /dev/ttyPCH0 low_latency
CAUSE:
Changing mode using setserial command, ".startup" function which gets DMA
channel is called before ".verify_port" function which sets
dma-flag(use_dma/use_dma_flag) as 1.
PIO->DMA
.startup: Since dma-flag is 0, DMA channel is not requested.
.verify_port: dma-flag is set as 1.
.shutdown: N/A
DMA->PIO
.startup: Since dma-flag is 1, DMA channel is requested.
.verify_port: dma-flag is set as 0.
.shutdown: Since dma-flag is 0, DMA channel is not released.
This means DMA channel resource leak occurs.
Next time, this driver can't get DMA channel resource forever.
MODIFICATION:
Currently, when release DMA channel resource, this driver checks dma-flag.
However, this specification occurs the above issue.
This driver must check whether dma_request_channel is executed or not.
The values are saved in private data variable "chan_tx/chan_tx".
These variables mean if the value is NULL, DMA channel is not requested,
if not NULL, DMA channel is requested.
This patch fixes the issue.

On Tegra UARTs (except UART1), the DTR / DCD / DSR lines are not
externally accessible. Instead, the DTR line internally appears to be
looped back to be the input to the DCD and DSR lines. The net effect
of this is that when we drop DTR (like when we suspend), we'll see DCD
drop too. ...and when we see DCD drop, we treat that as a hangup.
In order to prevent this hangup from occurring at every sleep, we need
to force DTR to remain high on Tegra UARTs.
This patch uses the mcr_mask / mcr_force fields, which were originally
added for the kludge ALPHA_KLUDGE_MCR. Using these fields does not
prevent us from removing ALPHA_KLUDGE_MCR--we can just remove the "if"
tests I have added and always init mcr_mask / mcr_force from the
serial8250_config.
NOTE: If we have people that are using UARTA on a Tegra and need to
control DTR, we'll need to either add a separate port type for UARTA
or we'll need to add some tegra-specific code to detect whether the
DTR needs to be left high.

Reading from the DCC grabs a character from the buffer and
clears the status bit. Since this is a context-changing
operation, instructions following the character read that rely on
the status bit being accurate need to be synchronized with an
ISB.
In this case, the status bit check needs to execute after the
character read otherwise we run the risk of reading the character
and checking the status bit before the read can clear the status
bit in the first place. When this happens, the user will see the
same character they typed twice, instead of once.
Add an ISB after the read and the write, so that the status check
is synchronized with the read/write operations.

ISSUE:
Using ML7831, MAC address writing doesn't work well.
CAUSE:
ML7831 and EG20T have the same register map for MAC address access.
However, this driver processes the writing the same as ML7223.
This is not true.
This driver must process the writing the same as EG20T.
This patch fixes the issue.

I get report from customer that his usb-serial
converter doesn't work well,it sometimes work,
but sometimes it doesn't.
The usb-serial converter's id:
vendor_id product_id
0x4348 0x5523
Then I search the usb-serial codes, and there are
two drivers announce support this device, pl2303
and ch341, commit 026dfaf1 cause it. Through many
times to test, ch341 works well with this device,
and pl2303 doesn't work quite often(it just work quite little).
ch341 works well with this device, so we doesn't
need pl2303 to support.I try to revert 026dfaf1 first,
but it failed. So I prepare this patch by hand to revert it.

The generic powersaving code that determines after reception of a frame
whether the device should go back to sleep or whether is could stay
awake was calling rt2x00lib_config directly from RX tasklet context.
On a number of the devices this call can actually sleep, due to having
to confirm that the sleeping commands have been executed successfully.
Fix this by moving the call to rt2x00lib_config to a workqueue call.
