[Paul Sajna]

Camera doesn't work yet (imx351), but we can use the flash as a flashlight.

[PATCH 2/4] arm64: dts: qcom: sdm845-lg-common: Change ipa gsi-loader to 'self', add memory-region

[Paul Sajna]

The modem firmware for this device doesn't preload the IPA firmware
and requires the OS handles that instead. Set qcom,gsi-loader = "self"
to reflect that.

Ensure the ipa uses the correct memory.

ipa 1e40000.ipa: channel 4 limited to 256 TREs
ipa 1e40000.ipa: IPA driver initialized
ipa 1e40000.ipa: received modem starting event
ipa 1e40000.ipa: received modem running event

[PATCH 3/4] arm64: dts: qcom: sdm845-lg-{judyln, judyp}: Reference memory region in fb

[Paul Sajna]

To prevent duplicating the framebuffer address and size point out the
existing framebuffer memory region instead of specifying the address
manually.

The WCN3990 firmware for judyln does not respond to the request for
host capabilities. Add the devicetree quirk to skip this request.
