Subject: arm64: dts: qcom: sdm845-lg-{judyln, judyp}: Reference memory region in fb
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=3f779220c64796df483c4cd47154d4ff1104a2e2;p=thirdparty%2Flinux.git

arm64: dts: qcom: sdm845-lg-{judyln, judyp}: Reference memory region in fb

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