[PATCH 0/2] MSM8998 describe wifi hardware

[Jeffrey Hugo]

We can describe the wifi hardware for the MSM8998 platforms.  The
firmware runs on the modem subsystem, which is pending clock changes, so
wifi won't be completely functional yet.  However, by describing the
wifi hardware, we can use it as soon as the modem pieces come in.

[PATCH 1/2] arm64: dts: qcom: msm8998: Add anoc2 smmu node

[Jeffrey Hugo]

While there are several peripherals on the anoc2, most are not behind the
smmu.  However, the SoC integrated wlan block is behind the smmu, so we'll
need to control the smmu inorder to enable wifi.

[PATCH 2/2] arm64: dts: qcom: msm8998: Add wifi node

[Jeffrey Hugo]

Add the wifi node and required reserved memory to enable the wlan
hardware.  Enable the wifi node in both the mtp and clamshell platforms
after adding the relevant regulators for each platform.
