2023-03-28arm64: dts: apple: t8103: Disable unused PCIe portsJanne Grunau
The PCIe ports are unused (without devices) so disable them instead of removing them. Fixes: 7c77ab91b33d ("arm64: dts: apple: Add missing M1 (t8103) devices") Signed-off-by: Janne Grunau <j@jannau.net> Reviewed-by: Sven Peter <sven@svenpeter.dev> Signed-off-by: Hector Martin <marcan@marcan.st>
2022-12-07arm64: dts: apple: Add t8103 L1/L2 cache properties and nodesJanne Grunau
The t8103 CPU nodes are missing the cache hierarchy information. The cache hierarchy on Arm can not be detected and needs to be described in DT. The OS scheduler can make use of this information for scheduling decisions. The cache size information is based on various articles about the processors. There's also an L3 system level cache (SLC). It's not described here because SLCs typically have some MMIO interface which would need to be described. Based on Rob Herring's patch adding cache properties and nodes for t600x.

2022-12-02arm64: dts: apple: Add CPU topology & cpufreq nodes for t8103Hector Martin
Add the missing CPU topology/capacity information and the cpufreq nodes, so we can have CPU frequency scaling and the scheduler has the information it needs to make the correct decisions. Boost states are commented out, as they are not yet available (that requires CPU deep sleep support, to be eventually done via PSCI). The driver supports them fine; the hardware will just refuse to ever go into them at this time, so don't expose them to users until that's done.

Pull ARM SoC devicetree updates from Arnd Bergmann: "As usual, this is the bulk of the updates for the SoC tree, adding more devices to existing files, addressing issues from ever improving automated checking, and fixing minor issues. The most interesting bits as usual are the new platforms. All the newly supported SoCs belong into existing families this time: - Qualcomm gets support for two newly announced platforms, both of which can now work in production environments: the SDX65 5G modem that can run a minimal Linux on its Cortex-A7 core, and the Snapdragon 8 Gen 1, their latest high-end phone SoC. - Renesas adds support for R-Car S4-8, the most recent automotive Server/Communication SoC. - TI adds support for J721s2, a new automotive SoC in the K3 family. - Mediatek MT7986a/b is a SoC used in Wifi routers, the latest generation following their popular MT76xx series. Only basic support is added for now. - NXP i.MX8 ULP8 is a new low-power variant of the widespread i.MX8 series. - TI SPEAr320s is a minor variant of the old SPEAr320 SoC that we have supported for a long time. New boards with the existing SoCs include - Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers - AT91/SAMA5 based evaluation board - NXP gains twenty new development and industrial boards for their i.MX and Layerscape SoCs - Intel IXP4xx now supports the final two machines in device tree that were previously only supported in old style board files. - Mediatek MT6589 is used in the Fairphone FP1 phone from 2013, while MT8183 is used in the Acer Chromebook 314. - Qualcomm gains support for the reference machines using the two new SoCs, plus a number of Chromebook variants and phones based on the Snapdragon 7c, 845 and 888 SoCs, including various Sony Xperia devices and the Microsoft Surface Duo 2. - ST STM32 now supports the Engicam i.Core STM32MP1 carrier board. - Tegra now boots various older Android devices based on 32-bit chips out of the box, including a number of ASUS Transformer tablets. There is also a new Jetson AGX Orin developer kit. - Apple support adds the missing device trees for all the remaining M1 Macbook and iMac variants, though not yet the M1 Pro/Max versions. - Allwinner now supports another version of the Tanix TX6 set-top box based on the H6 SoC. - Broadcom gains support for the Netgear RAXE500 Wireless router based on BCM4908" * tag 'dt-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (574 commits) Revert "ARM: dts: BCM5301X: define RTL8365MB switch on Asus RT-AC88U" arm64: dts: qcom: sm6125: Avoid using missing SM6125_VDDCX arm64: dts: qcom: sm8450-qrd: Enable USB nodes arm64: dts: qcom: sm8450: Add usb nodes ARM: dts: aspeed: add LCLK setting into LPC KCS nodes dt-bindings: ipmi: bt-bmc: add 'clocks' as a required property ARM: dts: aspeed: add LCLK setting into LPC IBT node ARM: dts: aspeed: p10: Add TPM device ARM: dts: aspeed: p10: Enable USB host ports ARM: dts: aspeed: Add TYAN S8036 BMC machine ARM: dts: aspeed: tyan-s7106: Add uart_routing and fix vuart config ARM: dts: aspeed: Adding Facebook Bletchley BMC ARM: dts: aspeed: g220a: Enable secondary flash ARM: dts: Add openbmc-flash-layout-64-alt.dtsi ARM: dts: aspeed: Add secure boot controller node dt-bindings: aspeed: Add Secure Boot Controller bindings ARM: dts: Remove "spidev" nodes dt-bindings: pinctrl: samsung: Add pin drive definitions for Exynos850 dt-bindings: arm: samsung: Document E850-96 board binding dt-bindings: Add vendor prefix for WinLink ...
