To meet this requirement, this device is added to genpd\nto control ISP power using runtime PM. The pm_runtime_get_sync() called\nbefore i2c_dw_probe() triggers PM resume, which powers on ISP and also\ninvokes the amdisp i2c runtime resume before the probe completes resulting\nin this race condition and a NULL dereferencing issue in v7.0\n\nFix this race condition by using the genpd APIs directly during probe:\n  - Call dev_pm_genpd_resume() to Power ON ISP before probe\n  - Call dev_pm_genpd_suspend() to Power OFF ISP after probe\n  - Set the device to suspended state with pm_runtime_set_suspended()\n  - Enable runtime PM only after the device is fully initialized"
