[PATCH v8 13/15] arm64: dts: qcom: sdm845-lg-common: Add camera flash

[Paul Sajna]

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

[PATCH v8 14/15] 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 v8 15/15] 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.
