[PATCH 1/2] arm64: dts: Add GPIO and GPIO keys device nodes

2018-04-15 Thread Baolin Wang 
This patch adds device nodes to enable one GPIO controller located on
digital chip, 2 EIC (external interrupt controller) controllers loacted
on PMIC and digital chip for Spreadtrum SC9860 platform.

Moreover this patch adds 3 GPIO keys relied on EIC controller to support
power key and volume up/down keys.

[PATCH 1/2] arm64: dts: Add GPIO and GPIO keys device nodes

2018-04-15 Thread Baolin Wang 
This patch adds device nodes to enable one GPIO controller located on
digital chip, 2 EIC (external interrupt controller) controllers loacted
on PMIC and digital chip for Spreadtrum SC9860 platform.

Moreover this patch adds 3 GPIO keys relied on EIC controller to support
power key and volume up/down keys.
