Since the main goal here has been to fix systemd suspend/resume, adjusting these callbacks is all that's being done when this flag gets set. And since I'm working on imx8mq, the 3rd patch makes gpcv2 set this new flag when a power domain has a power-supply descirbed in DT. For i.MX8M* platforms, this should be ok. For other platforms this might be useful too but needs to be tested. revision history ---------------- v5: (thank you Lucas) * simplify gpcv2 code: just set GENPD_FLAG_IRQ_ON when a power-supply is present v4: (thank you Ulf and Lucas) * split up genpd core and gpcv2 changes * set callbacks inside of pm_genpd_init() * make flag name and description a bit more generic * print an error in __genpd_dev_pm_attach() if there a "mismatch" https://lore.kernel.org/linux-arm-kernel/20220720043444.1289952-1-martin.kepplinger@puri.sm/T/#t v3: (thank you Ulf) * move DT parsing to gpcv2 and create a genpd flag that gets set https://lore.kernel.org/linux-arm-kernel/20220718210302.674897-1-martin.kepplinger@puri.sm/ v2: (thank you Krzysztof) * rewrite: find possible regulators' interrupts property in parents instead of inventing a new property. https://lore.kernel.org/linux-arm-kernel/20220712121832.3659769-1-martin.kepplinger@puri.sm/ v1: (initial idea) https://lore.kernel.org/linux-arm-kernel/20220711094549.3445566-1-martin.kepplinger@puri.sm/T/#t Martin Kepplinger (3): PM: domain: fix indentation and use BIT macro for flags power: domain: handle genpd correctly when needing interrupts soc: imx: gpcv2: fix suspend/resume by setting GENPD_FLAG_IRQ_ON drivers/base/power/domain.c | 13 +++++++++++++ drivers/soc/imx/gpcv2.c | 3 +++ include/linux/pm_domain.h | 20 +++++++++++++------- 3 files changed, 29 insertions(+), 7 deletions(-)
