[PATCH V6 0/4] Add PCIe M.2 Key E connector support for NXP i.MX boards

[PATCH V6 0/4] Add PCIe M.2 Key E connector support for NXP i.MX boards

[Sherry Sun (OSS)]

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

This series adds support for NXP Wi-Fi/BT combo chips (88W9098, AW693)
inserted into PCIe M.2 Key E connectors on i.MX95-19x19-EVK boards.

For M.2 cards that rely on PCIe L2 link state and wake-up mechanisms, the
card must remain powered during suspend. Patch #2 uses the existing
dw_pcie_rp::skip_pwrctrl_off flag to skip power-off during suspend and skip
power-on during the init path.

Also the btnxpuart driver is extended to obtain a pwrseq descriptor via the
OF graph on the UART controller device in patch #3.

---
Changes in V6:
1. Fix the power sequencer reference leak issue during BT driver unbound
   and re-bound in patch #3 issue that reported by sashiko.
2. Collected the Reviewed-by tags.

Changes in V5:
1. Improve the patch #1-3 commit message.
2. Remove the skip_pwrctrl_off flag check in imx_pcie_shutdown() in
   patch #2.
3. Add an explicit pwrseq_power_off() call in probe error path and
   nxp_serdev_remove() in patch #3.
4. Remove the imx8mq/imx8qm/imx8qxp/imx8dxl old platforms dts changes to
   avoid pcie functional break in some cases. For example, Uboot without
   M.2 driver support but use the new kernel dts file directly. 

Changes in V4:
1. Add a seperate patch to move pci_pwrctrl_create_devices() to
   imx_pcie_probe() as suggested by Frank.
2. Rebase the dts patches based on [2] patchset.
3. Drop pwrseq-pcie-m2 ID patch as it got applied.

Changes in V3:
1. Move pci_pwrctrl_create_devices() to imx_pcie_probe() in parch #1,
   similar to other regulator_get calls as suggested by Frank.
2. Collected the tags.

Changes in V2:
1. Rebased on top of 7.1.0.
2. Removed the power_off error handling in patch #3 because pwrseq_put()
   would call pwrseq_power_off() to automatically clean.
3. Collected the tags.

[PATCH V6 1/4] PCI: imx6: Move pci_pwrctrl_create_devices() to imx_pcie_probe()

[Sherry Sun (OSS)]

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

Previously, pci_pwrctrl_create_devices() was placed in
imx_pcie_host_init(), which is the .init callback of dw_pcie_host_ops.
This callback is invoked not only during probe, but also during resume.

This caused pci_pwrctrl_create_devices() to be called multiple
times across suspend/resume cycles, which is unnecessary since the
pwrctrl devices only need to be created once.

Move pci_pwrctrl_create_devices() to imx_pcie_probe() so that it is only
called once during probe, similar to other regulator_get calls.

[PATCH V6 2/4] PCI: imx6: Add skip_pwrctrl_off flag support

[Sherry Sun (OSS)]

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

Use dw_pcie_rp::skip_pwrctrl_off to avoid powering off devices during
suspend to preserve wakeup capability of the devices and also not to
power on the devices in the init path.

This allows controller power-off to be skipped when some devices (e.g.
M.2 Key E cards without auxiliary power) need to support PCIe L2 link
state and wake-up mechanisms.

[PATCH V6 3/4] Bluetooth: btnxpuart: Add M.2 Bluetooth device support using pwrseq

[Sherry Sun (OSS)]

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

Power supply to the M.2 Bluetooth device attached to the host using M.2
connector is controlled using the 'uart' pwrseq device. So add support
for getting the pwrseq device if the OF graph link is present.

Once obtained, pwrseq_power_on() is called to power up the M.2 Bluetooth
card. The power sequencer descriptor is obtained via pwrseq_get() with
the UART controller device (serdev->ctrl->dev), since the OF graph
link is defined on the UART controller node.

Also add the explicit pwrseq_put() call in all exit paths, pwrseq_put()
already calls pwrseq_power_off() internally, so no separate
pwrseq_power_off() call is needed.

fix the power sequencer reference leak issue during BT driver unload and
reload as reported by sashiko. I'm keeping your Reviewed-by tag. I can
