[PATCH 0/3] ARM: dts: keystone: fix and updates

[Grygorii Strashko]

Hi Santosh,

This serie contains fix of SPI nodes DT defintions for Keystone K2L  SoC.

Also It adds DT definitions for Keystone 2 DSP GPIO and IRQ controllers.


Grygorii Strashko (2):
  ARM: dts: keystone: add keystone irq controller node
  ARM: dts: keystone: add dsp gpio controllers nodes

[PATCH 2/3] ARM: dts: keystone: add dsp gpio controllers nodes

[Grygorii Strashko]

Add Keystone 2 DSP GPIO nodes for SoCs:
k2hk:
 DSP GPIO banks 0-7 correspond to DSP0-DSP7
k2l:
 DSP GPIO banks 0-3 correspond to DSP0-DSP3
k2e:
 DSP GPIO bank 0 corresponds to DSP0

[PATCH 3/3] ARM: dts: keystone: k2l: Fix chip selects for SPI devices

[Grygorii Strashko]

From: Murali Karicheri <m-karicheri2@ti.com>

There are 5 chip selects per SPI0 and SPI2 and 3 per SPI1. SPI2 needs
to be pinned out to use and by default they are disabled. So keep the
state disabled to reflect default.
