Marco Franchi	48c926cd34	dt-bindings: Remove leading zeros from bindings notation ... Improve the binding example by removing all the leading zeros to fix the following dtc warnings: Warning (unit_address_format): Node /XXX unit name should not have leading 0s Converted using the following command: perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find ./Documentation/devicetree/bindings "*.txt"` Some unnecessary changes were manually fixed.

Grygorii Strashko	2134cb997f	gpio: syscon: reuse for keystone 2 socs ... On Keystone SOCs, ARM host can send interrupts to DSP cores using the DSP GPIO controller IP. Each DSP GPIO controller provides 28 IRQ signals for each DSP core. This is one of the component used by the IPC mechanism used on Keystone SOCs. Keystone 2 DSP GPIO controller has specific features: - each GPIO can be configured only as output pin; - setting GPIO value to 1 causes IRQ generation on target DSP core; - reading pin value returns 0 - if IRQ was handled or 1 - IRQ is still pending. This patch updates gpio-syscon driver to be reused by Keystone 2 SoCs, because the Keystone 2 DSP GPIO controller is controlled through Syscon devices and, as requested by Linus Walleij, such kind of GPIO controllers should be integrated with drivers/gpio/gpio-syscon.c driver.
