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 is basically a resend from February 2020 which went without feedback. 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 Guido Günther (1): phy: fsl-imx8-mipi-dphy: Hook into runtime pm .../phy/freescale/phy-fsl-imx8-mipi-dphy.c | 22 ++++++++++++++++++- 1 file changed, 21 insertions(+), 1 deletion(-) -- 2.29.2
