[RFC v1 0/9] gpio: davinci: reuse for keystone arch

[Grygorii Strashko <grygorii.strashko@ti.com>]

This series is intended to update Davinci GPIO driver and reuse
it for Keystone SoCs, because Keystone uses the similar GPIO IP like Davinci.
Keystone GPIO IP: supports:
- up to 32 GPIO lines;
- only unbanked irqs;

See Documentation:
Keystone - http://www.ti.com/lit/ug/sprugv1/sprugv1.pdf

[1] Depends on patch:
"[PATCH 1/2] gpio: davinci: Fix a check for unbanked gpio"
https://lkml.org/lkml/2013/11/8/22

[2] and depends on series from Prabhakar Lad:
"[PATCH v6 0/6] gpio: daVinci: cleanup and feature enhancement"
https://www.mail-archive.com/devicetree@vger.kernel.org/msg05970.html

Based on:
git://git.kernel.org/pub/scm/linux/kernel/git/ssantosh/linux-keystone.git
branch: keystone/master

This series has been marked as RFC because it's based on an unfinished
series of patches [2], but with hope that it will help to reach final decisions 
and satisfy all interested parties.

Grygorii Strashko (9):
  gpio: davinci: get rid of DAVINCI_N_GPIO
  gpio: introduce GPIO_DAVINCI kconfig option
  gpio: davinci: use chained_irq_enter/chained_irq_exit API
  gpio: davinci: make IRQ initialization soc specific
  gpio: davinci: reuse for Keystone SoC
  arm: dts: keystone: add GPIO device entry
  ARM: keystone_defconfig: enable gpio support
  arm: dts: keystone-evm: add LEDs supports
  ARM: keystone_defconfig: enable LED support
