-Subject: arm64: dts: rockchip: Add missing PCIe supplies to RockPro64 board
- dtsi
-
-From: Dragan Simic <dsimic@manjaro.org>
-
-[ Upstream commit ffcef3df680c437ca33ff434be18ec24d72907c2 ]
-
-Add missing "vpcie0v9-supply" and "vpcie1v8-supply" properties to the "pcie0"
-node in the Pine64 RockPro64 board dtsi file. This eliminates the following
-warnings from the kernel log:
-
- rockchip-pcie f8000000.pcie: supply vpcie1v8 not found, using dummy regulator
- rockchip-pcie f8000000.pcie: supply vpcie0v9 not found, using dummy regulator
-
-These additions improve the accuracy of hardware description of the RockPro64
-and, in theory, they should result in no functional changes to the way board
-works after the changes, because the "vcca_0v9" and "vcca_1v8" regulators are
-always enabled. [1][2] However, extended reliability testing, performed by
-Chris, [3] has proven that the age-old issues with some PCI Express cards,
-when used with a Pine64 RockPro64, are also resolved.
-
-Those issues were already mentioned in the commit 43853e843aa6 (arm64: dts:
-rockchip: Remove unsupported node from the Pinebook Pro dts, 2024-04-01),
-together with a brief description of the out-of-tree enumeration delay patch
-that reportedly resolves those issues. In a nutshell, booting a RockPro64
-with some PCI Express cards attached to it caused a kernel oops. [4]
-
-Symptomatically enough, to the commit author's best knowledge, only the Pine64
-RockPro64, out of all RK3399-based boards and devices supported upstream, has
-been reported to suffer from those PCI Express issues, and only the RockPro64
-had some of the PCI Express supplies missing in its DT. Thus, perhaps some
-weird timing issues exist that caused the "vcca_1v8" always-on regulator,
-which is part of the RK808 PMIC, to actually not be enabled before the PCI
-Express is initialized and enumerated on the RockPro64, causing oopses with
-some PCIe cards, and the aforementioned enumeration delay patch [4] probably
-acted as just a workaround for the underlying timing issue.
-
-Admittedly, the Pine64 RockPro64 is a bit specific board by having a standard
-PCI Express slot, allowing use of various standard cards, but pretty much
-standard PCI Express cards have been attached to other RK3399 boards as well,
-and the commit author is unaware ot such issues reported for them.
-
-It's quite hard to be sure that the PCI Express issues are fully resolved by
-these additions to the DT, without some really extensive and time-consuming
-testing. However, these additions to the DT can result in good things and
-improvements anyway, making them perfectly safe from the standpoint of being
-unable to do any harm or cause some unforeseen regressions.
-
-These changes apply to the both supported hardware revisions of the Pine64
-RockPro64, i.e. to the production-run revisions 2.0 and 2.1. [1][2]
