Way of storing current state of pins before suspend entry and restoring Use syscore and waiting on suggestion from Linux Walleij for any better Patch 0002: This version still using syscore. Gpiolib for some cleanup before adding hierarchical support. Parent to GPIOs for GPIO wake event support. Removed gpio-tegra changes for hierarchical support to have PMC as W.r.t DFLL resume for restoring CPU clock. Tegra210 clock suspend/resume as they need to be in proper sequence Note: Peripheral clocks and clock enable and reset need to be in Plls, pll outs and dividers in corresponding drivers. Implemented save_context and restore_context callbacks for clock So using resume_noirq for gpio tegra to allow GPIO restore should happen prior to Pinctrl restore to prevent Sequence and its dependency on peripheral clocks restore.
Added more comments in tegra210_clk_resume regarding dfll restore
ENBSERIES 279 UPDATE
Created separate patch for fence_delay update during PLLU init based Implemented all peripheral clocks save and restore through theirĬorresponding clk_ops save_context and restore_context and removedĪll direct registers store and restore in clk-tegra210 driver. Parked_bit is updated to parked_bitmask to use with DRV_PINGROUPĪs well and thierry posted patch series for this. Removed park bits clear for EMMC pads in pinctrl-tegra driverįunction tegra_pinctrl_clear_parked_bits as based on V3 feedback Added save and restore support for super clock driver.
ENBSERIES 279 DRIVER
Fix to super clock driver to enable PLLP branch to CPU before Switch source to safe source of PLLP and disable DFLL clock. Add suspend and resume support for CPUFreq driver to explicitly DFLL suspend and resume moved to DFLL clock driver
