This patch series includes Tegra210 deepsleep support with RTC alarm wake event. This series also includes save and restore of PLLs, clocks, OSC contexts for deepsleep exit to normal operation. This patch series doesn't support 100% suspend/resume to allow fully functional state upon resume and we are working on some more drivers suspend and resume implementations. [V4]: Changes between V3 & V4 are - V3 feedback fixes - Removed park bits clear for EMMC pads in pinctrl-tegra driver function tegra_pinctrl_clear_parked_bits as based on V3 feedback parked_bit is updated to parked_bitmask to use with DRV_PINGROUP as well and thierry posted patch series for this. - Implemented all peripheral clocks save and restore through their corresponding clk_ops save_context and restore_context and removed all direct registers store and restore in clk-tegra210 driver. - Created separate patch for fence_delay update during PLLU init based on V3 feedback. - Added more comments in tegra210_clk_resume regarding dfll restore sequence and its dependency on peripheral clocks restore. [V3]: Changes between V2 & V3 are - V2 feedback fixes - GPIO restore should happen prior to Pinctrl restore to prevent glitch on GPIO lines. So using resume_noirq for gpio tegra to allow gpio resume prior to pinctrl resume. - Implemented save_context and restore_context callbacks for clock plls, pll outs and dividers in corresponding drivers. Note: Peripheral clocks and clock enable and reset need to be in Tegra210 clock suspend/resume as they need to be in proper sequence w.r.t DFLL resume for restoring CPU clock. - Removed gpio-tegra changes for hierarchical support to have PMC as parent to GPIOs for GPIO wake event support. Thierry is working on gpiolib for some cleanup before adding hierarchical support. So holding on to GPIO wake support for now. [V2] : V1 feedback fixes Patch 0002: This version still using syscore. Thierry suggest not to use syscore and waiting on suggestion from Linux Walleij for any better way of storing current state of pins before suspend entry and restoring them on resume at very early stage. So left this the same way as V1 and will address once I get more feedback on this. Also need to findout and implement proper way of forcing resume order between pinctrl and gpio driver. [V1]: Tegra210 SC7 entry and exit thru RTC wake and Power button GPIO wake using hierarchical IRQ with PMC as parent to GPIO.
