From: Thierry Reding <treding@xxxxxxxxxx> Hi Rafael, Kevin, Ulf, This series implement generic power domains for Tegra186. Since the power partitions on Tegra186 have a non-contiguous ID range, the PM domain core is enhanced with a way to allow PM domain providers to override the default ->xlate() implementation. This is used to look up the correct PM domain given the ID read from device tree. The second patch updates the BPMP ABI header to a version that has support for the MRQ_PG request which is used to enumerate available power partitions and control them. An implementation of the generic PM domains using the MRQ_PG request is provided in patch 3. Given the dependency of patch 3 on patch 1 I think it'd be easiest to get an Acked-by on patch 1 and take all of these through the Tegra tree. If that's okay with you, I can provide a stable branch with the first patch that could be pulled into the PM tree to resolve potential conflicts. Thanks, Thierry Changes in v2: - take into account PG_STATE_RUNNING in tegra_bpmp_powergate_is_powered() - check return value of pm_genpd_init() and clean up on failure - simplify error unwinding in tegra_bpmp_init_powergates() Thierry Reding (3): PM / Domains: Allow overriding the ->xlate() callback soc/tegra: bpmp: Update ABI header soc/tegra: bpmp: Implement generic PM domains drivers/base/power/domain.c | 8 +- drivers/firmware/tegra/bpmp.c | 4 + drivers/soc/tegra/Kconfig | 5 + drivers/soc/tegra/Makefile | 1 + drivers/soc/tegra/powergate-bpmp.c | 359 +++++++++++++++++++++++++++++++ include/linux/pm_domain.h | 4 + include/soc/tegra/bpmp-abi.h | 418 ++++++++++++++++++++++++++++++++++++- include/soc/tegra/bpmp.h | 12 ++ 8 files changed, 797 insertions(+), 14 deletions(-) create mode 100644 drivers/soc/tegra/powergate-bpmp.c -- 2.12.0 -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
