Subject: [PATCHv4 0/3] Enable Quark X1000 support in gpio-sch

Hi all,

This is a revised version for enabling Quark X1000 support in gpio-sch.
This version of patch series had changed according to the feedback provided
by Alexandre and Mika.

Change log for V4:
Patch 1:
- Removed redundant/duplicated functions of sch_gpio_register_set() and
  sch_gpio_register_clear(). The function call had been replaced by
  sch_gpio_reg_set(gc, gpio, reg, 1) in place of sch_gpio_register_set() and
  sch_gpio_reg_set(gc, gpio, reg, 0) for sch_gpio_register_clear().
- Resolved double spinlock issue caught by Alexandre.

Patch 3:
- Dropped the usage of "if" block that checking irq_data struct
- Restructured the irq detect by using platform_get_irq(pdev, 0) instead of
  platform_get_resource(pdev, IORESOURCE_IRQ, 0) to get IRQ resources from
  MFD LPS-SCH.

The patches need to be patched on top of Mika Westerberg's commit at:
gpio: sch: Consolidate core and resume banks
http://marc.info/?l=linux-kernel&m=141392647225885&w=2

The patches has been verifed and tested working on Galileo Board. GPIO sysfs
was able to export gpio pins and changing pin direction. GPIO values were
able to controlled and interrupt was enabled.

Please help to review the patches so that we can make it to upstream kernel
as soon as possible. Thanks for all the review comments during this period of
review cycle.

Regards,
Rebecca

Change log for V3:
Patch 3:
- Change variable type of irq_support to bool.
- Update error message and remove redundant code.
- Revert gpiochip_remove() to avoid it to return a value.

Change log for V2:
Patch 1:
- Move sch_gpio_get() and sch_gpio_set() to avoid forward declaration.
- Changed sch_gpio_enable()/sch_gpio_disable() to sch_gpio_register_set()/
  sch_gpio_register_clear().

Patch 3:
- Changed all sch_gpio_enable()/sch_gpio_disable() to sch_gpio_register_set()/
  sch_gpio_register_clear().

Version 1:
Initial version.
