Subject: [PATCH 2/3] arm64: dts: lx2160a: add lx2160acex7 device tree
The device tree enables the following features -
1. dpmac17 RGMII MAC connected to Atheros AR8035 phy
2. 2x MDIO busses
3. 2x USB 3.0 controllers
4. 4x SATA ports
5. MT35X 512Mb SPI flash
6. Temperature sensor on i2c0 channel 3
7. AMC6821 temperature and PWM fan controller
The module supports AMC6821 and EMC2301 PWM controllers where either can
be assembled, but not both together since the PWM and TACH signals are
shared between them.

Subject: [PATCH 3/3] arm64: dts: lx2160a: misc fixes
those are misc fixes that will be removed in some point.
the first is build amc6821 support
the second is setting default amc6821 default poalirty to be active
high; this modification will not be needed in REV 1.4 of the COM express
module since the inversion will be on the module.
