Hi, This is a continuation of [1], where Ulf Hansson suggested to factor out GENPD patches into a separate series. This series is a prerequisite of the power domain driver for NVIDIA Tegra SoCs. [1] https://patchwork.ozlabs.org/project/linux-tegra/list/?series=221130 Changelog: v3: - Added r-b from Ulf Hansson. - Added new patch "Make of_genpd_add_subdomain() to return -EPROBE_DEFER", which was suggested by Ulf Hansson. - Improved "Add "performance" column to debug summary" patch by correcting the formatting of debug output, which had a superfluous whitespace.
