soc: hisilicon: Support HCCS driver on Kunpeng SoC

2023-08-08T12:36:29+00:00

The Huawei Cache Coherence System (HCCS) is a multi-chip interconnection bus protocol. This driver is aimed to support some features about HCCS on Kunpeng SoC, like, querying the health status of HCCS. This patch adds the probing of HCCS driver, and obtains all HCCS port information by the dimension of chip and die on platform. Signed-off-by: Huisong Li Signed-off-by: Wei Xu

soc: nuvoton: Add SoC info driver for WPCM450

2023-02-01T16:11:36+00:00

Add a SoC information driver for Nuvoton WPCM450 SoCs. It provides information such as the SoC revision. Usage example: # grep . /sys/devices/soc0/* /sys/devices/soc0/family:Nuvoton NPCM /sys/devices/soc0/revision:A3 /sys/devices/soc0/soc_id:WPCM450 Signed-off-by: Jonathan Neuschäfer Reviewed-by: Joel Stanley Reviewed-by: Paul Menzel Link: https://lore.kernel.org/r/20221031223926.241641-1-j.neuschaefer@gmx.net Signed-off-by: Joel Stanley Link: https://lore.kernel.org/r/20230201051717.1005938-1-joel@jms.id.au Signed-off-by: Arnd Bergmann

soc: starfive: Add StarFive JH71XX pmu driver

2023-01-20T21:55:59+00:00

Add pmu driver for the StarFive JH71XX SoC. As the power domains provider, the Power Management Unit (PMU) is designed for including multiple PM domains that can be used for power gating of selected IP blocks for power saving by reduced leakage current. It accepts software encourage command to switch the power mode of SoC. Signed-off-by: Walker Chen Reviewed-by: Conor Dooley Reviewed-by: Heiko Stuebner Signed-off-by: Conor Dooley

soc: loongson: add GUTS driver for loongson-2 platforms

2022-11-14T15:01:32+00:00

The global utilities block controls PCIE device enabling, alternate function selection for multiplexed signals, consistency of HDA, USB and PCIE, configuration of memory controller, rtc controller, lio controller, and clock control. This patch adds a driver to manage and access global utilities block for LoongArch architecture Loongson-2 SoCs. Initially only reading SVR and registering soc device are supported. Other guts accesses, such as reading firmware configuration by default, should eventually be added into this driver as well.

soc: fujitsu: Add A64FX diagnostic interrupt driver

2022-07-18T11:37:08+00:00

Register the NMI/IRQ corresponding to the A64FX's device definition dedicated to diagnostic interrupts, so that when this interrupt is sent using the BMC, it causes a panic. This can be used to obtain a kernel dump. Signed-off-by: Hitomi Hasegawa Link: https://lore.kernel.org/r/20220520074119.3574753-2-hasegawa-hitomi@fujitsu.com' Signed-off-by: Arnd Bergmann

ARM: pxa: move plat-pxa to drivers/soc/

2022-05-07T20:56:16+00:00

There are two drivers in arch/arm/plat-pxa: mfp and ssp. Both of them should ideally not be needed at all, as there are proper subsystems to replace them. OTOH, they are self-contained and can simply be normal SoC drivers, so move them over there to eliminate one more of the plat-* directories.

soc: apple: Add driver for Apple PMGR power state controls

2021-12-07T04:13:13+00:00

Implements genpd and reset providers for downstream devices. Each instance of the driver binds to a single register and represents a single SoC power domain. The driver does not currently implement all features (clockgate-only state, misc flags), but we declare the respective registers for documentation purposes. These features will be added as they become useful for downstream devices. This also creates the apple/soc tree and Kconfig submenu. Acked-by: Linus Walleij Signed-off-by: Hector Martin

Pull RISC-V updates from Palmer Dabbelt: "A handful of new RISC-V related patches for this merge window: - A check to ensure drivers are properly using uaccess. This isn't manifesting with any of the drivers I'm currently using, but may catch errors in new drivers. - Some preliminary support for the FU740, along with the HiFive Unleashed it will appear on. - NUMA support for RISC-V, which involves making the arm64 code generic. - Support for kasan on the vmalloc region. - A handful of new drivers for the Kendryte K210, along with the DT plumbing required to boot on a handful of K210-based boards. - Support for allocating ASIDs. - Preliminary support for kernels larger than 128MiB. - Various other improvements to our KASAN support, including the utilization of huge pages when allocating the KASAN regions. We may have already found a bug with the KASAN_VMALLOC code, but it's passing my tests. There's a fix in the works, but that will probably miss the merge window. * tag 'riscv-for-linus-5.12-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: (75 commits) riscv: Improve kasan population by using hugepages when possible riscv: Improve kasan population function riscv: Use KASAN_SHADOW_INIT define for kasan memory initialization riscv: Improve kasan definitions riscv: Get rid of MAX_EARLY_MAPPING_SIZE soc: canaan: Sort the Makefile alphabetically riscv: Disable KSAN_SANITIZE for vDSO riscv: Remove unnecessary declaration riscv: Add Canaan Kendryte K210 SD card defconfig riscv: Update Canaan Kendryte K210 defconfig riscv: Add Kendryte KD233 board device tree riscv: Add SiPeed MAIXDUINO board device tree riscv: Add SiPeed MAIX GO board device tree riscv: Add SiPeed MAIX DOCK board device tree riscv: Add SiPeed MAIX BiT board device tree riscv: Update Canaan Kendryte K210 device tree dt-bindings: add resets property to dw-apb-timer dt-bindings: fix sifive gpio properties dt-bindings: update sifive uart compatible string dt-bindings: update sifive clint compatible string ...

ARM: remove zte zx platform

2021-01-20T09:24:19+00:00

The ZTE ZX set-top-box SoC platform was added in 2015 by Jun Nie, with Baoyou Xie and Shawn Guo subsequently becoming maintainers after the addition of the 64-bit variant. However, the only machines that were ever supported upstream are the reference designs, not actual set-top-box devices that would benefit from this support. All ZTE set-top-boxes from the past few years seem to be based on third-party SoCs. While there is very little information about zx296702 and zx296718 on the web, I found some references to other chips from the same family, such as zx296716 and zx296719, which were never submitted for upstream support. Finally, there is no support for the GPU on either of them, with the lima and panfrost device drivers having been added after work on the zx platform had stopped. Shawn confirmed that he has not seen any interest in this platform for the past four years, and that it can be removed. Thanks to Jun and Shawn for maintaining this platform over the past five years.
