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

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
