Subject: ARM: dts: aspeed: g6: Add PWM/Tach controller node
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6cf976b2728f2494215c51c7339dd50b154125ce;p=thirdparty%2Fkernel%2Flinux.git

ARM: dts: aspeed: g6: Add PWM/Tach controller node

Introduce a device tree node for the AST2600 PWM/Tach controller.
Describe register range, clock, reset, and cell configuration.
Set status to "disabled" by default.

Prepares for enabling PWM and tachometer support on platforms
utilizing this SoC.
