ENGR00279413 pxp/v4l2: get the right framebuffer start address at run time
Previously the driver gets the framebuffer start address at probe time.
But this address might be changed if the framebuffer drivers re-allocate
the frame buffers due to the application changes the yres_virtual.
As a result, some garbage data can be observed on display.
This patch adjusts the way to detect the start address at run time to
fix this problem.
The following commit introduced a wrong sanity check for
the io_regulator which is intended to be got from device tree. a364635a535705a8c16df49ff9bc7b9362b083ec

ENGR00258733 WEIM-NOR: mtd: cfi_cmdset_0002: Do not release the mutex lock
The NOR(M29W256GL7AN6E) may suffers a write-buffer timeout during
the bonnie++/ubifs stress test. Micron has confirmed that it is
a silicon bug in the Nor.
This patch is just a workaround to fix this issue for this NOR.
With this patch, the read/write/erase will do in the synchronous way.
ENGR00257947 mtd: use memcpy to replace the memcpy_fromio
During the read of NOR, the kernel actually calls the inline_map_copy_from()
to read the data out. And inline_map_copy_from() will use the memcpy_fromio()
to do the real job.
The memcpy_fromio macro maps _memcpy_fromio() in the current code.
But the _memcpy_fromio() will use readb() to do the copy work one byte
by one byte. This makes the read performance of NOR very slow(about 2~3MB/s).
A similiar discussion could be found in:
http://lists.infradead.org/pipermail/linux-arm-kernel/2009-November/003860.html
This patch replace the memcpy_fromio with memcpy which is optimized by the
kernel.

Connecting two boards directly more than 2 hours, Ar8031 phy link

ethernet still be active. There have three cases to validate the issue:
Item#1: If add performance stress test while runing IEEE1588, the link
down/up issue cannot be found.
Item#2: If insert switch between two net nodes and run IEEE1588 test,
the issue also cannot be found.
Item#3: If disable AR8031 SmartEEE feature, after two days overnight test,
no such issue found.
The issue is caused by phy Ar8031 SmartEEE feature, Item#1 and Item#2 can
prevent phy enter lpm mode, which match the Item#3 test result, so disable
SmartEEE feature to avoid the link issue generation.
Current driver only do phy reset in probe function, which is
not right. Since some phy clock is disabled after module probe,
the phy enter abnormal status, which needs do reset to recovery
the phy. And do ifconfig ethx up/down test, the phy also enter
abnormal status.
The log as:
libphy: 2188000.ethernet:04 - Link is Up - 10/Full
libphy: 2188000.ethernet:04 - Link is Up - 100/Full
libphy: 2188000.ethernet:04 - Link is Down

libphy: 2188000.ethernet:04 - Link is Up - 10/Full
libphy: 2188000.ethernet:04 - Link is Up - 100/Full
...
So, do phy reset if ethx up/down or do clock enable/disable
operation.
