The alternative would be to drop the dphy from the mipi power domain in the SOCs device tree and only have the DSI host controller visible there but since the PD is mostly about the PHY that would defeat it's purpose. This allows to shut off the power domain hen blanking the LCD panel: pm_genpd_summary before: domain status slaves /device runtime status ---------------------------------------------------------------------- mipi on /devices/platform/soc@0/soc@0:bus@30800000/30a00300.dphy unsupported /devices/platform/soc@0/soc@0:bus@30800000/30a00000.mipi_dsi suspended after: mipi off-0 /devices/platform/soc@0/soc@0:bus@30800000/30a00300.dphy suspended /devices/platform/soc@0/soc@0:bus@30800000/30a00000.mipi_dsi suspended Changes from v1: - Tweak commit message slightly Changes from v2: - As per review comment by Lucas Stach https://lore.kernel.org/linux-arm-kernel/ee22b072e0abe07559a3e6a63ccf6ece064a46cb.camel@pengutronix.de/ Check for pm_runtime_get_sync failure Changes from v3: - As per review comment by Liu Ying https://lore.kernel.org/linux-arm-kernel/424af315b677934fe6a91cee5a0a7aee058245a9.camel@nxp.com/ https://lore.kernel.org/linux-arm-kernel/a98f7531b9d0293d3c89174446f742d4199cb27c.camel@nxp.com/ - Use phy layers runtime pm - simplify mixel_dphy_remove Guido Günther (1): phy: fsl-imx8-mipi-dphy: Hook into runtime pm drivers/phy/freescale/phy-fsl-imx8-mipi-dphy.c | 10 ++++++++++ 1 file changed, 10 insertions(+) -- 2.30.0
