[PATCH V3 0/8] PCI: imx6: Integrate pwrctrl API and update device trees

[PATCH V3 0/8] PCI: imx6: Integrate pwrctrl API and update device trees

[Sherry Sun (OSS)]

From: Sherry Sun <sherry.sun@nxp.com>

This series integrates the PCI pwrctrl framework into the pci-imx6
driver and updates i.MX EVK board device trees to support it.

Patches 2-8 update device trees for i.MX EVK boards which maintained
by NXP to move power supply properties from the PCIe controller node
to the Root Port child node, which is required for pwrctrl framework.
Affected boards:
- i.MX6Q/DL SABRESD
- i.MX6SX SDB
- i.MX8MM EVK
- i.MX8MP EVK
- i.MX8MQ EVK
- i.MX8DXL/QM/QXP EVK
- i.MX95 15x15/19x19 EVK

The driver maintains legacy regulator handling for device trees that
haven't been updated yet. Both old and new device tree structures are
supported.

Changes in V3:
1. Rebased on top of latest 7.1.0-rc4

Changes in V2:
1. After commit 2d8c5098b847 ("PCI/pwrctrl: Do not power off on pwrctrl
   device removal"), the pwrctrl drivers no longer power off devices
   during removal. Update pci-imx6 driver's shutdown callback in patch#1
   to explicitly call pci_pwrctrl_power_off_devices() before 
   pci_pwrctrl_destroy_devices() to ensure devices are properly powered
   off.

[PATCH V3 1/8] PCI: imx6: Integrate new pwrctrl API for pci-imx6

[Sherry Sun (OSS)]

From: Sherry Sun <sherry.sun@nxp.com>

Integrate the PCI pwrctrl framework into the pci-imx6 driver to provide
standardized power management for PCIe devices.

Legacy regulator handling (vpcie-supply at controller level) is
maintained for backward compatibility with existing device trees.
New device trees should specify power supplies at the Root Port
level to utilize the pwrctrl framework.

Hi Sherry:
Since the vpcie3v3aux is used to power up the WAKE#, it is always on in this
pwrctrl framework whatever the system is in suspend or not, right?

Hi Richard,
Currently the new pwrctrl framework doesn't support vpcie3v3aux, it handles all
regulators with of_regulator_bulk_get_all() and regulator_bulk_enable/disable().
The vpcie3v3aux now only works with pci-imx6 driver.

PWRCTRL_GENERIC driver can handle both vpcie3v3 and vpcie3v3aux, but not
POWER_SEQUENCING_PCIE_M2 driver, as there is no 3.3Vaux defined in M.2 spec.
