Some smart panel requires a delay between command sequences, while PXA
LCD controller didn't provide such one, let's emulate this by software.
A software delay marker can be inserted into the command sequence, once
pxafb_smart_queue() detects this, it flushes the previous commands and
delay for a specified number of milliseconds.

For smart panels (LCD panel with internal framebuffer), the following
LCCR3 register bits have different meanings than the parallel one:
LCCR3_PCP - controls the L_PCLK_WR polarity
LCCR3_HSP - controls the L_LCLK_A0 polarity
LCCR3_VSP - controls the L_FCLK_RD polarity
To keep minimum change to the original parallel timing, the .lcd_conn
flags and 'pxafb_mode_info.sync' are re-used to reflect this:
LCD_PCLK_EDGE_{RISE,FALL} - configures LCCR3_PCP
sync & FB_SYNC_{HOR,VERT}_HIGH_ACT - configures LCCR3_{HSP,VSP}

This patch adds HP iPAQ h5000's (h5400, h5500) basic definitions.
Kernel will able to boot, work via serial console, mount filesystems
placed on flashes and run USB gadgets (g_ether by default).
Other device drivers (frame buffer, LCD, touchscreen, backlight,
bluetooth, w1/battery, ...) are depend on SAMCOP and MediaQ
SoCs/MFDs, drivers to which will be submitted too, after massive
cleanups.
This machine will be used as "real user" for these new drivers.
This is an updated version of the patch, which contains fixes proposed on
linux-arm-kernel mailing list.

Change the halt and reboot method from gpio based to "jump
to ROM IPL beginning". This gives control back to IPL, which
without PowerOn key pressed, will put the device into deep
sleep until PowerOn is pressed for 1 second.
But this has the benefit of keeping the RTC registers across
reboots, which is good for OS change.

Following the removal of the "->policy" usage for PXA255 in patch
459fc208ab (cpufreq: remove
policy->governor setting in drivers initialization), this patch
introduces an option (called "pxa255_turbo_table") to select either
the "run" or "turbo" frequency table.
It also cures the runtime warning that was printed each time the
frequency was changed.
Got rid of all references to CPUFREQ_POLICY_* for pxa255, and sticked
with the run/turbo thing.
Tested on an Arcom/Eurotech Viper.

Original patch from Marek Vasut, the problems with PXA26x are:
1. there are additional 4 GPIOs 86,87,88,89 have their direction bits
inverted in GPDR2, as well as their alternate function bits being
'1' for their GPIO functionality in GAFRx
2. there is no easy way to decide if the processor is a pxa26x or a
pxa250/pxa255 at run-time, so the assumption here is the pxa26x
will be treated as one of the pxa25x variants, and board code
should have a better knowledge of the processor it is featured
Introduce pxa26x_init_irq() for the second purpose, and treat the
additional GPIOs > 85 on PXA25x specially.
Kconfig option CONFIG_CPU_PXA26x is introduced to optimize the code
a bit when PXA26x support isn't needed. Board config options have
to select this to enable the support for PXA26x.
__gpio_is_inverted() will be optimized way when CONFIG_CPU_PXA26x
isn't selected.

The 'gpio_nr' can really be inferred by 'pxa_last_gpio', and since we
already have that variable, remove the unnecessary 'gpio_nr' now.
Also, fix the incorrect GPIO number passed in pxa27x_init_irq().
Note: pxa_last_gpio should be initialized earlier, and this is true
since it's been assigned in machine_desc->init_irq().
