[RFC/RFT PATCH 0/7] gpio: omap: rework and fixes

[Grygorii Strashko <grygorii.strashko@xxxxxxxxxx>]

Hi Tony,

As I promised in [1] I've prepared a new series for OMAP GPIO driver.

Patches 1-2 are bug fixes.

Patches 3-6 is attempt (RFC/RFT) to rework OMAP GPIO driver taking into account
that GPIO Chip and GPIO IRQ Chip functionality are mostly orthogonal.

Patch 7 is second attempt (RFC/RFT) to Runtime PM APIs without checking current
GPIO bank's state with BANK_USED() macro.

Based on top of:
 030bbdb Linux 4.1-rc3

Tested on
  dra7-evm, gpiosysfs, GPIO IRQ only

[1] gpio: omap: Fix PM runtime issue and remove most BANK_USED macros

[2] [RFC/RFT PATCH 2/2] gpio: omap: ensure that runtime pm will disable unused gpio banks
    http://marc.info/?l=linux-gpio&m=142567003515626&w=2

Grygorii Strashko (7):
  gpio: omap: fix omap_gpio_free to not clean up irq configuration
  gpio: omap: fix error handling in omap_gpio_irq_type
  gpio: omap: rework omap_x_irq_shutdown to touch only irqs specific registers
  gpio: omap: rework omap_gpio_request to touch only gpio specific registers
  gpio: omap: rework omap_gpio_irq_startup to handle current pin state properly
  gpio: omap: clean up omap_gpio_irq_type
  gpio: omap: ensure that runtime pm will disable unused gpio banks
