- Created a worker thread to centralize all update requests (new and collisions)
- Added routine to merge compatible updates
- Separated PXP processing from update ioctl and ISR flows into workqueue flow
- Added IOCTL to turn control the update scheme. Supported schemes
are snapshot mode (the old update scheme), queued mode, and queued mode
with combining.
- Added collision-handling refinement based on update submission order
- Added support for 8bpp setting from kernel command line option

The usb wakeup thread should be prior to usb system resume
during usb wakeup process. It adds wait_event_interruptible
at usb resume process, and the usb wakeup irq will set event,
and the usb wakeup thread will clear event.

FB_SYNC_EXT was used to represent ext clk, but actually, it represent ext sync.
Some applications do not recognize it, during fb_set_var ioctl may miss it,
which will cause fb display fail, for example X window startup.
Remove FB_SYNC_EXT flag, and choose ext clk support by ipu driver.
If you want to use ipu internal clk only, you can add int_clk to your video
option like below:
video=mxcdi0fb:RGB565,800x480M@55,int_clk

This patch adds a notifier which can be used by subsystems that may
be interested in when a task has completely died and is about to
have it's last resource freed.
The Android lowmemory killer uses this to determine when a task
it has killed has finally given up its goods.

not requiring the specified size to be page aligned,
instead rounding it internally as needed, and does not

Driver part
Add usb low power and wakeup support for mx28 usb1, in that means,
when the usb h1 is not in used, the host1 will close
usb core and phy's clock. When an usb activity happens,
the usb can be wakeup from low power mode.
Meanwhile, the usb host1 can also be system
wakeup source through sys entry like other platforms.

Not all the NAND devices have all the information in additional
id bytes.
So add a hook in the nand_chip{} is a good method to calculate the
right value of oobsize, erasesize and so on.
Without the hook,you will get the wrong value, and you have to hack
in the ->scan_bbt() to change the wrong value which make the code
mess.

- User can specify a flag (EPDC_FLAG_FORCE_MONOCHROME) to have 8-bit grayscale
converted to monochrome (black or white) via processing in the PxP
(using the LUT).
- Added logic to check against the full videomode when identifying the
desired FB mode. This allows support for multiple modes with the same
dimensions.

- MAX17135 re-architected:
- Core functionality, including I2C access to the chip, moved into
drivers/mfd/max17135-core.c
- MAX17135 regulators registered via init() callback in plat-specific
code.
- All access to registers funnelled through max17135_reg_read/write() apis.
- max17135.h moved from regulator/ folder into mfd/ folder.
- Support for reading internal and external temperature via sysfs interface,
consistent with lm-sensors hwmon interface.

The phy_mii_ioctl() function unnecessarily throws away the original ifreq.
We need access to the ifreq in order to support PHYs that can perform
hardware time stamping.
Two maverick drivers filter the ioctl commands passed to phy_mii_ioctl().
This is unnecessary since phylib will check the command in any case.

Enable the configurations of the boot enable on the eMMC cards.
Add the interface that used to configure the boot_bus_width
In order to make sure that the re-read the ext-csd of card
can be completed successfully, add the method to wait for
the finish of the busy state.
NOTE:
The following are the valid inputs when configure the boot
bus width of the eMMC cards.
+--------------------------------------------------------------------+
| Bit7 Bit6 Bit5 | Bit4 Bit3 | Bit2 | Bit1 Bit0 |
|----------------|----------------------------------|----------------|
| X | BOOT_MODE | RESET_BOOT_BUS_WIDTH | BOOT_BUS_WIDTH |
+--------------------------------------------------------------------+
Bit [4:3] : BOOT_MODE (non-volatile)
0x0 : Use single data rate + backward compatible timings in boot
operation (default)
0x1 : Use single data rate + high speed timings in boot operation mode
0x2 : Use dual data rate in boot operation
0x3 : Reserved
Bit [2]: RESET_BOOT_BUS_WIDTH (non-volatile)
0x0 : Reset bus width to x1, single data rate and backward compatible
timings after boot operation (default)
0x1 : Retain boot bus width and boot mode after boot operation
Bit[1:0] : BOOT_BUS_WIDTH (non-volatile)
0x0 : x1 (sdr) or x4 (ddr) bus width in boot operation mode (default)
0x1 : x4 (sdr/ddr) bus width in boot operation mode
0x2 : x8 (sdr/ddr) bus width in boot operation mode
0x3 : Reserved
The following are the valid inputs when configure the boot
partitions of the eMMC cards.
+------------------------------------------------------------+
| Bit7 | Bit6 | Bit5 Bit4 Bit3 | Bit2 Bit1 Bit0 |
|------|----------|-----------------------|------------------|
| X | BOOT_ACK | BOOT_PARTITION_ENABLE | PARTITION_ACCESS |
+------------------------------------------------------------+
Bit7: Reserved
Bit6: always set to vaule '1' when boot_part is enabled
Bit[5:3]:
0x0 : Device not boot enabled (default)
0x1 : Boot partition 1 enabled for boot
0x2 : Boot partition 2 enabled for boot
0x7 : User area enabled for boot
Bit[2:0]:
0x0 : No access to boot partition (default)
0x1 : R/W boot partition 1
0x2 : R/W boot partition 2
So only the '0, 1, 2; 8, 9, 10; 16, 17, 18; 56, 57, 58' are
valid parameters when configure the boot_partiton.

commit 685fd0b4ea3f0f1d5385610b0d5b57775a8d5842 upstream.
A small number of users of IRQF_TIMER are using it for the implied no
suspend behaviour on interrupts which are not timer interrupts.
Therefore add a new IRQF_NO_SUSPEND flag, rename IRQF_TIMER to
__IRQF_TIMER and redefine IRQF_TIMER in terms of these new flags.
