pmdomain: Rename the genpd subsystem to pmdomain

2023-09-13T09:09:21Z

It has been pointed out that naming a subsystem "genpd" isn't very self-explanatory and the acronym itself that means Generic PM Domain, is known only by a limited group of people. In a way to improve the situation, let's rename the subsystem to pmdomain, which ideally should indicate that this is about so called Power Domains or "PM domains" as we often also use within the Linux Kernel terminology.

Pull ARM SoC driver updates from Arnd Bergmann: "The main change this time was the introduction of the drivers/genpd subsystem that gets split out from drivers/soc to keep common functionality together. The SCMI driver subsystem gets an update to version 3.2 of the specification. There are also updates to memory, reset and other firmware drivers. On the soc driver side, the updates are mostly cleanups across a number of Arm platforms. On driver for loongarch adds power management for DT based systems, another driver is for HiSilicon's Arm server chips with their HCCS system health interface. The remaining updates for the most part add support for additional hardware in existing drivers or contain minor cleanups. Most of these are for the Qualcomm Snapdragon platform" * tag 'soc-drivers-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (136 commits) bus: fsl-mc: Use common ranges functions soc: kunpeng_hccs: fix some sparse warnings about incorrect type soc: loongson2_pm: add power management support soc: dt-bindings: add loongson-2 pm soc: rockchip: grf: Fix SDMMC not working on RK3588 with bus-width > 1 genpd: rockchip: Add PD_VO entry for rv1126 bus: ti-sysc: Fix cast to enum warning soc: kunpeng_hccs: add MAILBOX dependency MAINTAINERS: remove OXNAS entry dt-bindings: interrupt-controller: arm,versatile-fpga-irq: mark oxnas compatible as deprecated irqchip: irq-versatile-fpga: remove obsolete oxnas compatible soc: qcom: aoss: Tidy up qmp_send() callers soc: qcom: aoss: Format string in qmp_send() soc: qcom: aoss: Move length requirements from caller soc: kunpeng_hccs: fix size_t format string soc: ti: k3-socinfo.c: Add JTAG ID for AM62PX dt-bindings: firmware: qcom: scm: Updating VMID list firmware: imx: scu-irq: support identifying SCU wakeup source from sysfs firmware: imx: scu-irq: enlarge the IMX_SC_IRQ_NUM_GROUP firmware: imx: scu-irq: add imx_scu_irq_get_status ...

Pull ARM SoC generic power domain driver updates from Ulf Hansson: "This adds a new subsystem for generic power domain providers in drivers/genpd and starts moving some of the corresponding code in there. We have currently ~60 users of the genpd provider interface, which are sprinkled across various subsystems. To release some burden from the soc maintainers (Arnd Bergmann, etc) in particular, but also to gain a better overall view of what goes on in the area, I will help out with maintenance" [ I find the "genpd" name singularly uninformative, so we'll probably end up moving this driver subsystem somewhere else, but that's still being discussed - Linus ] * tag 'genpd-v6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/linux-pm: (30 commits) genpd: ti: Use for_each_node_with_property() simplify code logic genpd: Explicitly include correct DT includes genpd: imx: scu-pd: initialize is_off according to HW state genpd: imx: scu-pd: Suppress bind attrs genpd: imx: scu-pd: do not power off console if no_console_suspend genpd: imx: scu-pd: add more PDs genpd: imx: scu-pd: enlarge PD range genpd: imx: relocate scu-pd under genpd MAINTAINERS: adjust file entry in STARFIVE JH71XX PMU CONTROLLER DRIVER genpd: Makefile: build imx genpd: move owl-sps-helper.c from drivers/soc soc: starfive: remove stale Makefile entry ARM: ux500: Move power-domain driver to the genpd dir ARM: ux500: Convert power-domain code into a regular platform driver soc: xilinx: Move power-domain driver to the genpd dir soc: ti: Mover power-domain drivers to the genpd dir soc: tegra: Move powergate-bpmp driver to the genpd dir soc: sunxi: Move power-domain driver to the genpd dir soc: starfive: Move the power-domain driver to the genpd dir soc: samsung: Move power-domain driver to the genpd dir ...

genpd: imx: scu-pd: initialize is_off according to HW state

2023-08-17T09:33:54Z

The current code default set is_off to true except console resource, this implies bootloader should power off all the resources it uses. But this is not always true, let's check the HW state and set is_off. Signed-off-by: Peng Fan Signed-off-by: Ulf Hansson

This driver is registered as platform driver, but removing and binding again would cause system not workable. So suppress bind attrs. Signed-off-by: Peng Fan Signed-off-by: Ulf Hansson

Do not power off console if no_console_suspend, this will leave the serial device's corresponding PM domain on during system suspend, which is useful for debug system suspend. Signed-off-by: Peng Fan Signed-off-by: Ulf Hansson
