This series adds support for dev_pm_genpd_set_hwmode() and dev_pm_genpd_get_hwmode() APIs and support in gdsc provider drivers to register respective callbacks and venus consumer driver example using above API to switch the power domain(GDSC) to HW/SW modes dynamically at runtime. This is resend of V5 series, added R-By tags received in V5 for 1st & 2nd patches. Link to V5: https://lore.kernel.org/all/20240315111046.22136-1-quic_jkona@xxxxxxxxxxx/ Changes in V5: - Updated 1st patch as per V4 review comments to synchronize the initial HW mode state by invoking ->get_hwmode_dev()callback in genpd_add_device() - With above change, SW cached hwmode will contain correct value initially, and it will be updated everytime mode is changed in set_hwmode, hence updated dev_pm_genpd_get_hwmode() to just return SW cached hwmode in 1st patch - Updated commit text for 1st, 3rd, 4th and 5th patches - Updated 3rd and 5th patches as per review comments received on V4 series - Added R-By tags received in older series to 1st and 2nd patches Previous series: V4: https://lore.kernel.org/all/20240122-gdsc-hwctrl-v4-0-9061e8a7aa07@xxxxxxxxxx/ V3: https://lore.kernel.org/lkml/20230823114528.3677667-1-abel.vesa@xxxxxxxxxx/ V2: https://lore.kernel.org/lkml/20230816145741.1472721-1-abel.vesa@xxxxxxxxxx/ V1: https://lore.kernel.org/all/20230628105652.1670316-1-abel.vesa@xxxxxxxxxx/ Abel Vesa (1): PM: domains: Add the domain HW-managed mode to the summary Jagadeesh Kona (3): clk: qcom: gdsc: Add set and get hwmode callbacks to switch GDSC mode clk: qcom: Use HW_CTRL_TRIGGER flag to switch video GDSC to HW mode venus: pm_helpers: Use dev_pm_genpd_set_hwmode to switch GDSC mode on V6 Ulf Hansson (1): PM: domains: Allow devices attached to genpd to be managed by HW drivers/clk/qcom/gdsc.c | 37 +++++++++ drivers/clk/qcom/gdsc.h | 1 + drivers/clk/qcom/videocc-sc7280.c | 2 +- drivers/clk/qcom/videocc-sm8250.c | 4 +- .../media/platform/qcom/venus/pm_helpers.c | 39 ++++++---- drivers/pmdomain/core.c | 78 ++++++++++++++++++- include/linux/pm_domain.h | 17 ++++ 7 files changed, 157 insertions(+), 21 deletions(-) -- 2.43.0
