Hi, This series aims to solve power-off failures and occasional SMI hang issues that occur during camera stress tests. The issue arises because, when MTCMOS powers on or off, signal glitches are sometimes produced. This is fairly normal, but the software must address it to avoid mistaking the glitch for a transaction signal. The solutions in these patches can be summarized as follows: 1. Disable the sub-common port after turning off the Larb CG and before turning off the Larb MTCMOS. 2. Use CLAMP to disable/enable the SMI common port. 3. Implement an AXI reset. For previous discussion on the direction of the code modifications, please refer to: https://lore.kernel.org/linux-arm-kernel/c476cc48-17ec-4e14-98d8-35bdffb5d296@xxxxxxxxxxxxx/ Change in v2 - fix commit title to "pmdomain: mediatek:" - add dt-binding definition - remove unused function yu-chang.lee (3): pmdomain: mediatek: add smi_larb_reset function when power on dt-bindings: power: Add mediatek larb definition pmdomain: mediatek: support smi clamp protection .../power/mediatek,power-controller.yaml | 4 + drivers/pmdomain/mediatek/mt8188-pm-domains.h | 69 ++++++- drivers/pmdomain/mediatek/mtk-pm-domains.c | 168 ++++++++++++++---- drivers/pmdomain/mediatek/mtk-pm-domains.h | 13 ++ 4 files changed, 218 insertions(+), 36 deletions(-) -- 2.18.0
