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.

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.
