+# 2026-05-16 bisect note: the linux-rk3588-marfrit branch tip @ f8f3ad9
+# (18 commits ahead of v7.0-rc3) BLACK-SCREENS ampere — connector
+# reports connected/enabled/dpms On + SDDM starts + backlight on, but
+# panel shows no pixels. Decomposing the suspend/resume patch (0010
+# family) into 5 atomic sub-commits and reverting all 5 did NOT recover
+# display (test-arch-plus-pcie3 branch). The 6 patches listed below
+# applied on top of v7.0-rc3 directly DO boot with working display
+# (ampere-minimal-devices branch @ 7c241f2). Regression source is in
+# one of the remaining 12 commits in f8f3ad9 — top suspect:
+# 55d1b3dcc05e "clk: rockchip: rk3588: Drop CLK_SET_RATE_PARENT from
+# DCLK_VOP2_SRC" (touches display controller clock parent rate). Other
+# excluded commits: Shawn Lin pcie3 phy series, Cristian Ciocaltea
+# clk/dts/dw-dp fixes, Sebastian Reichel hdmirx Rock 5 ITX, Pedro Alves
+# btrtl, and the suspend/resume patch 0010 family. Bisect campaign
+# separately.

+# Branch ampere-minimal-devices on git.reauktion.de/marfrit/linux-rk3588-marfrit
