2021-12-16arm64: tegra: Remove unsupported regulator propertiesThierry Reding2-13/+0
Remove the unsupported "regulator-disable-ramp-delay" properties which ended up in various DTS files for some reason. Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-12-16arm64: tegra: Rename TCU node to "serial"Thierry Reding1-1/+1
The TCU is basically a serial port (albeit a fancy one), so it should be named "serial". Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-12-16arm64: tegra: Remove undocumented Tegra194 PCIe "core_m" clockThierry Reding1-3/+2
The "core_m" clock is not documented in the Tegra194 PCIe device tree bindings, so remove it. Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-12-16arm64: tegra: Drop unused properties for Tegra194 PCIeThierry Reding1-15/+0
The num-viewport property is never used and can be dropped, whereas the "iommus" property is not needed since we use "iommu-map-mask" and "iommu-map" already. Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-12-16arm64: tegra: Fix Tegra194 HSP compatible stringThierry Reding1-2/+2

2021-12-16arm64: tegra: Drop unsupported nvidia,lpdr propertyThierry Reding1-2/+0
The Tegra194 pinmux DT bindings do not define the nvidia,lpdr property, so drop them from the device trees that have listed them. Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-12-16arm64: tegra: Use JEDEC vendor prefix for SPI NOR flash chipsThierry Reding2-2/+2
The standard "jedec," vendor prefix should be used for SPI NOR flash chips. This allows the right DT schema to be picked for validation. Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-12-16arm64: tegra: Drop unit-address for audio card graph endpointsThierry Reding3-7/+7
Audio graph endpoints don't have a "reg" property, so they shouldn't have a unit-address either. Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-12-16arm64: tegra: Adjust length of CCPLEX cluster MMIO regionThierry Reding1-1/+1
The Tegra186 CCPLEX cluster register region is 4 MiB is length, not 4 MiB - 1. This was likely presumed to be the "limit" rather than length. Fix it up. Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-12-16arm64: tegra: Fix Tegra186 compatible string listThierry Reding1-9/+9

2021-12-16arm64: tegra: Rename power-monitor input nodesThierry Reding3-16/+16
Child nodes of the TI INA3221 power monitor device tree node should be called input@* according to the DT schema. Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-12-16arm64: tegra: Rename thermal zones nodesThierry Reding8-55/+49
The DT schema requires that nodes representing thermal zones include a "-thermal" suffix in their name. Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-12-16arm64: tegra: Sort Tegra132 XUSB clocks correctlyThierry Reding1-2/+2
Make the order of the clocks and clock-names properties match the order in the device tree bindings. This isn't strictly necessary from a point of view of the operating system because matching will be done based on the clock-names, but it makes it easier to validate the device trees against the DT schema. Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-12-16arm64: tegra: Drop unused AHCI clocks on Tegra132Thierry Reding1-4/+2
The CML1 and PLL_E clocks are never explicitly used by the AHCI controller found on Tegra132, so drop them from the corresponding device tree node. Signed-off-by: Thierry Reding <treding@nvidia.com>

Add peripheral OPP tables on Tegra132 and wire them up to ACTMON and the EMC. While at it, add the missing "#interconnect-cells" properties to the memory controller and external memory controller nodes. Also set the "#reset-cells" property for the memory controller because it exports the hotflush reset controls. Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-12-16arm64: tegra: Fix compatible string for Tegra132 timerThierry Reding1-1/+1

2021-12-16arm64: tegra: Fix unit-addresses on NorrinThierry Reding1-3/+3
The AS3722 pinmux device tree node doesn't have a "reg" property and therefore must not have a unit-address, so drop it. While at it, add missing unit-addresses for the charger and smart battery IC's on the ChromeOS embedded controller's I2C tunnel bus. Signed-off-by: Thierry Reding <treding@nvidia.com>

2021-12-16arm64: tegra: Rename top-level regulatorsThierry Reding12-86/+86
Regulators defined at the top level in device tree are no longer part of a simple bus and therefore don't have a reg property. Nodes without a reg property shouldn't have a unit-address either, so drop the unit address from the node names. To ensure nodes aren't duplicated (in which case they would end up merged in the final DTB), append the name of the regulator to the node name. Signed-off-by: Thierry Reding <treding@nvidia.com>

The display controllers are attached to a separate ARM SMMU instance that is dedicated to servicing isochronous memory clients. Add this ISO instance of the ARM SMMU to device tree. Please note that the display controllers are not hooked up to this SMMU yet, because we are still missing a means to transition framebuffers used by the bootloader to the kernel.

2021-12-16arm64: tegra: Fixup SYSRAM referencesThierry Reding3-6/+6
The json-schema bindings for SRAM expect the nodes to be called "sram" rather than "sysram" or "shmem". Furthermore, place the brackets around the SYSRAM references such that a two-element array is created rather than a two-element array nested in a single-element array. This is not relevant for device tree itself, but allows the nodes to be properly validated against json-schema bindings. Signed-off-by: Thierry Reding <treding@nvidia.com>

2021-12-16dt-bindings: memory: tegra: Update for Tegra194Thierry Reding1-11/+67
The #interconnect-cells properties are required to hook up memory clients to the MC/EMC in interconnects properties. Add a description for these properties. For the nested EMC controller, the list of required properties was missing. Add it so that the validation can be more strict. Also, allow multiple reg entries required by Tegra194 and later. While at it, also remove the dummy BPMP node from the example because it is incomplete and fails validation. It's also not necessary for this file and the BPMP DT schema already has a full example.

2021-11-14kconfig: Add support for -Wimplicit-fallthroughGustavo A. R. Silva2-5/+6
Add Kconfig support for -Wimplicit-fallthrough for both GCC and Clang. The compiler option is under configuration CC_IMPLICIT_FALLTHROUGH, which is enabled by default. Special thanks to Nathan Chancellor who fixed the Clang bug[1][2]. This bugfix only appears in Clang 14.0.0, so older versions still contain the bug and -Wimplicit-fallthrough won't be enabled for them, for now. This concludes a long journey and now we are finally getting rid of the unintentional fallthrough bug-class in the kernel, entirely. :) Link: https://github.com/llvm/llvm-project/commit/9ed4a94d6451046a51ef393cd62f00710820a7e8 [1] Link: https://bugs.llvm.org/show_bug.cgi?id=51094 [2] Link: https://github.com/KSPP/linux/issues/115 Link: https://github.com/ClangBuiltLinux/linux/issues/236 Co-developed-by: Kees Cook <keescook@chromium.org> Signed-off-by: Kees Cook <keescook@chromium.org> Co-developed-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Gustavo A.
