[PATCH 1/3] i.MX51: handle IRQ for gpio 16..31

[PATCH 1/3] i.MX51: handle IRQ for gpio 16..31

[Eric Bénard]

The i.MX51 generates 2 IRQ for each GPIO bank : one for gpio 0 to 15
and one for gpio 16 to 31.
Actually only the lower IRQ is registered so register the second one.

[PATCH v2 3/3] i.MX51: add support for cpuimx51 module and its baseboard

[Eric Bénard]

CPUIMX51 is build around Freescale's i.MX515 and has up to
512MB of RAM, NAND Flash, Ethernet, USB Host with 4 ports
hub, USB OTG, ST16554 Quad UART on nCS1, I2C RTC ...

MBIMX51 adds LEDS, Keypad, TSC2007 touchscreen controler ...

This is making an assumption that the high irq line is 1 more than low
one. There is no guarantee this will always be true. This will also then
require change when adding MX53 support and other new chips in the
pipeline.

Adding irq_high field to struct mxc_gpio_port and setting up the handler
when it is non-zero will avoid a cpu_is_x.

OK, I'll update the patch this way.

[PATCH v2 1/3] i.MX51: handle IRQ for gpio 16..31

[Eric Bénard]

The i.MX51 generates 2 IRQ for each GPIO bank : one for gpio 0 to 15
and one for gpio 16 to 31.
Actually only the lower IRQ is registered so register the second one.

v2 :
	add irq_high to struct mxc_gpio_port as per Rob Herring's

There are several occurences of the string "babbage" left in this file.

struct plat_serial8250_port has the irqflags field which should be used
here.

I'm not entirely happy with this. I think this should be in a file with
"baseboard" in its file name rather than being named after the board. I
realized you have the prototype for the baseboard init function for
other eukrea boards in board specific header files aswell. How about
creating a single eukrea-baseboards.h file where all available eukrea
baseboards are combined?

OK, is it possible that you apply this patch :
http://lists.infradead.org/pipermail/linux-arm-kernel/2010-July/020755.html
then I'll merge all the .h in one and add the i.MX51 on top of this.

Thanks
Eric

[PATCH v3] i.MX51: add support for cpuimx51 module and its baseboard

[Eric Bénard]

CPUIMX51 is build around Freescale's i.MX515 and has up to
512MB of RAM, NAND Flash, Ethernet, USB Host with 4 ports
hub, USB OTG, ST16554 Quad UART on nCS1, I2C RTC ...

MBIMX51 adds LEDS, Keypad, TSC2007 touchscreen controler ...
