2021-10-04ARM: at91: pm: preload base address of controllers in tlbClaudiu Beznea
In suspend/resume procedure for AT91 architecture different controllers (PMC, SHDWC, RAM, RAM PHY, SFRBU) are accessed to do the proper settings for power saving. Commit f0bbf17958e8 ("ARM: at91: pm: add self-refresh support for sama7g5") introduced the access to RAMC PHY controller for SAMA7G5. The access to this controller is done after RAMC ports are closed, thus any TLB walk necessary for RAMC PHY virtual address will fail. In the development branch this was not encountered. However, on current kernel the issue is reproducible. To solve the issue the previous mechanism of pre-loading the TLB with the RAMC PHY virtual address has been used. However, only the addition of this new pre-load breaks the functionality for ARMv5 based devices (SAM9X60). This behavior has been encountered previously while debugging this code and using the same mechanism for pre-loading address for different controllers (e.g. pin controller, the assumption being that other requested translations are replaced from TLB). To solve this new issue the TLB flush + the extension of pre-loading the rest of controllers to TLB (e.g. PMC, RAMC) has been added. The rest of the controllers should have been pre-loaded previously, anyway.

2021-09-14ARM: at91: pm: switch backup area to vbat in backup modeClaudiu Beznea
Backup area is now switched to VDDIN33 at boot (with the help of bootloader). When switching to backup mode we need to switch backup area to VBAT as all the other power sources are cut off. The resuming from backup mode is done with the help of bootloader, so there is no need to do something particular in Linux to restore backup area power source.

2021-07-19ARM: at91: pm: save ddr phy calibration data to securamClaudiu Beznea
The resuming from backup mode is done with the help of bootloader. The bootloader reconfigure the DDR controller and DDR PHY controller. To speed-up the resuming process save the PHY calibration data into SECURAM before suspending (securam is powered on backup mode). This data will be later used by bootloader in DDR PHY reconfiguration process. Also, in the process or recalibration the first 8 words of the memory may get corrupted. To solve this, these 8 words are saved in the securam and restored by bootloader in the process of PHY configuration.

2020-07-18ARM: at91: pm: add missing put_device() call in at91_pm_sram_init()yu kuai
if of_find_device_by_node() succeed, at91_pm_sram_init() doesn't have a corresponding put_device(). Thus add a jump target to fix the exception handling for this function implementation.

This reverts commit 2725d70aa5138284ba2cebf0ef51dd23e0c9ea21 ("ARM: at91: pm: do not disable/enable PLLA for ULP modes"). This is because PLLA is the clock source for CPU, PLLA should be disabled/enabled in the final/first phase of suspend/resume so that the power consumption in suspend/resume to be minimal and suspend/resume time to be minimized.

2020-02-18ARM: at91: pm: use proper master clock register offsetClaudiu Beznea
SAM9X60's PMC has different master clock register offset than the other SoCs' PMC. Due to this, specify master clock register offset based on PMC compatible and pass it to pm_suspend.S since it is also needed in there. When PM part for SAM9X60 was published the SAM9X60's PMC (commit f6deae46039c ("clk: at91: add sam9x60 pmc driver")) wasn't integrated.
