Nothing change, just to follow the new way for the definition.

Nothing change, just to follow the new way *_egpio function.

Remain out only micro that have to be full rewriten and uda1341 OSS

Hi to all,
another patch for iPAQ h3600

epiphany patch :
* arch/arm/common/ipaq/micro.c :
    - estetic code clean-up
    - support for keys device
    - backlight device definition
    - backlight are now restored after framebuffer blank/resume

* arch/arm/common/ipaq/micro_key.c :
    - support for keys (5 application keys and 4 directions pad)

* arch/arm/common/pxa_keys.c :
    - moved from arch/arm/mach-pxa/pxa_keys.c
    - small changes to be used also for h3600 device

* arch/arm/mach-sa1100/h3600.c
    - add support for power and action keys
    - backlight device definition moved in micro.c

* include/asm-arm/arch-pxa/pxa_keys.h
    - to not break existing pxa code it only include hardware/pxa_keys.h

* include/asm-arm/arch-sa1100/h3600_gpio.h
    - add definition for GPIO number (not bit) for action button

* include/asm-arm/arch-sa1100/h3600.h
    - add definition for GPIO number (not bit) for power button

* include/asm-arm/arch-sa1100/irqs.h
    - macro to get IRQ for a giver GPIO

* include/asm-arm/hardware/pxa_keys.h
    - moved from include/asm-arm/arch-pxa/pxa_keys.h

There are still some issues with micro* modules after sustend/resume and
when unloading.

This is really the epyphany patch, the end of xmas vacation.
 From monday work and pool start again and so spare time will be just
few hours for day. :)
But i'll continue ...

I'm also looking on ebay if I can find a cheap h37xx and h38xx to take
care of such iPAQs also.

Actually, correction: it'd be correct if you ripped out the buggy
calls to manage the irq wake mechanism. A later message will show
how those need to work. (The IRQ framework will give one helpful
hint when it warns about mismatched enable/disable calls ...)

iPAQ h3600 - patch for 2.6.19


From: Alessandro GARDICH <gremlin_at_gremlin.it>
Date: Sun, 10 Dec 2006 18:07:13 +0100

Hi all

With this patch also h3600 will compile and run kernel 2.6.19

- irq calling loose registers parameter
- platform device/driver in h3600_lcd
- minor cleanup

see u soon

A fast note about performance:

It seems that the performance problem is not the imageon itself. After
one of my tests, I found in my dmesg lines like:

<4>Alignment trap: font (1269) PC=0x4002f9f4 Instr=0xe592c000 Address=0x00012726 FSR 0x013

The problem is the font itself: as any character is 14 bytes (for the
7x14 font) not all the char pointers fall in a word boundary and so,
we're forcing the cpu to correct the missalignment.

I have a little libw100 test program, to fill the screen with a given
text. This is what I got when I use a nonaligned char, like "1":

root_at_c7x0:/media/card/libw100/bin$ ./font 0 1 "1"
Written 3094 characters in 19 seconds. Rate: 162.422116 cps

And using an aligned one, like "2":

root_at_c7x0:/media/card/libw100/bin$ ./font 0 1 "2"
Written 3094 characters in 0 seconds. Rate: 16563.169165 cps

This is like the performance I got using the 8x16 font, so, the problem
seems to be the misalignment of the font, and not the imageon itself.

Regards.
