Currently we wait only until the PGC inverts the isolation setting before disabling the peripheral clocks. This doesn't ensure that the reset is properly propagated through the peripheral devices in the power domain. Wait until the PGC signals that the power up request is done and wait a bit for resets to propagate before disabling the clocks. Signed-off-by:

The soc-imx8.c driver is actually for i.MX8M family, so rename it to soc-imx8m.c. Use CONFIG_SOC_IMX8M as build gate, not CONFIG_ARCH_MXC, to control whether build this driver, also make it possible for compile test. Default set it to y for ARCH_MXC && ARM64 Signed-off-by:

Use PDR helper functions to track the protection domains that the apr services are dependent upon on SDM845 SoC, specifically the "avs/audio" service running on ADSP Q6. Reviewed-by:

Qualcomm SoCs (starting with MSM8998) allow for multiple protection domains (PDs) to run on the same Q6 sub-system. This allows for services like AVS AUDIO to have their own separate address space and crash/recover without disrupting the other PDs running on the same Q6 ADSP. Add "qcom,protection-domain" bindings to capture the dependencies between the APR service and the PD on which the apr service runs. Reviewed-by:

Qualcomm SoCs (starting with MSM8998) allow for multiple protection domains to run on the same Q6 sub-system. This allows for services like ATH10K WLAN FW to have their own separate address space and crash/recover without disrupting the modem and other PDs running on the same sub-system. The PDR helpers introduces an abstraction that allows for tracking/controlling the life cycle of protection domains running on various Q6 sub-systems. Signed-off-by:

Commit adb72394 ("ARM: OMAP2+: Drop legacy platform data for am3 lcdc") dropped legacy platform data but we never added the quirks for SWSUP_SIDLE and SWSUP_MSTANDBY for lcdc for ti-sysc driver. This breaks suspend/resume. Let's fix the issue by enabling the same quirks for ti-sysc driver as we had earlier with platform data.

The PRU-ICSS present on AM33xx/AM43xx/AM57xx has a very unique SYSCFG register. The register follows the OMAP4-style SYSC_TYPE3 for Master Standby and Slave Idle, but also has two additional unique fields - STANDBY_INIT and SUB_MWAIT. The STANDBY_INIT is a control bit that is used to initiate a Standby sequence (when set) and trigger a MStandby request to the SoC's PRCM module. This same bit is also used to enable the OCP master ports (when cleared) to allow the PRU cores to access any peripherals or memory beyond the PRU subsystem. The SUB_MWAIT is a ready status field for the external access. Add support for this SYSC type. The STANDBY_INIT has to be set during suspend, without which it results in a hang in the resume sequence on AM33xx/AM43xx boards and requires a board reset to come out of the hang. Any PRU applications requiring external access are supposed to clear the STANDBY_INIT bit. Note that the PRUSS context is lost during a suspend sequence because the PRUSS module is reset and/or disabled. Signed-off-by:

In order to probe EDMA with ti-sysc interconnect target module and with device tree data, we need to properly detect EDMA and set the flags for SYSC_QUIRK_SWSUP_SIDLE | SYSC_QUIRK_SWSUP_MSTANDBY for tptc. We have these flags currently set for am4 and dra7, but not for am335x. Let's set them for all the SoCs as the tptc module should behave the same for all of them. It's likely that am335x was never tested to idle EDMA tptc. Cc: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: -
