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 any power-supply's parent DT node has "interrupts" described. For i.MX8M* platforms, this should be ok. For other platforms this might be useful too but needs to be tested. revision history ---------------- 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" 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 | 9 +++++++++ include/linux/pm_domain.h | 20 +++++++++++++------- 3 files changed, 35 insertions(+), 7 deletions(-)
