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

genpd: move owl-sps-helper.c from drivers/soc

2023-07-26T12:41:01+00:00

Moving only one of the two files in drivers/soc/actions to drivers/genpd caused a link failure in allmodconfig, as drivers/genpd is entered for compile testing, but drivers/soc/actions accidentally got skipped: x86_64-linux-gnu-ld: vmlinux.o: in function `owl_sps_set_power': owl-sps.c:(.text+0x16e259d): undefined reference to `owl_sps_set_pg' Move the other one as well to allow build testing to work correctly.

Merge patch series "JH7110 PMU Support"

2023-01-20T21:57:00+00:00

Walker Chen says: Add the PMU (Power Management Unit) controller driver for the StarFive JH7110 SoC. In order to meet low power requirements, 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.

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.
