PCI: j721e: Add suspend and resume support

2024-09-04T14:09:33Z

Add suspend and resume support. Only the Root Complex mode is supported. During the suspend stage PERST# is asserted, then deasserted during the resume stage.

PCI: j721e: Use T_PERST_CLK_US macro

2024-09-04T14:09:33Z

Use the T_PERST_CLK_US macro, and the fsleep() function instead of usleep_range(). Link: https://lore.kernel.org/linux-pci/20240102-j7200-pcie-s2r-v7-6-a2f9156da6c3@bootlin.com Signed-off-by: Thomas Richard Signed-off-by: Krzysztof Wilczyński

PCI: cadence: Drop excess cdns_pcie_rc.dev kerneldoc description

2024-09-03T21:16:23Z

Struct cdns_pcie_rc once had a .dev member, but it was removed by bd22885aa188 ("PCI: cadence: Refactor driver to use as a core library"). Drop the extra kerneldoc for it. Signed-off-by: Bjorn Helgaas

PCI: j721e: Add reset GPIO to struct j721e_pcie

Add reset GPIO to struct j721e_pcie, so it can be used at suspend and resume stages. Link: https://lore.kernel.org/linux-pci/20240102-j7200-pcie-s2r-v7-4-a2f9156da6c3@bootlin.com Signed-off-by: Théo Lebrun Signed-off-by: Thomas Richard Signed-off-by: Krzysztof Wilczyński

PCI: j721e: Use dev_err_probe() in the probe() function

2024-09-03T18:27:15Z

Use dev_err_probe() instead of dev_err() in the probe() function to simplify the code and standardize the error output.

PCI: cadence: Set cdns_pcie_host_init() global

2024-09-03T18:27:14Z

During the resume sequence of the host, cdns_pcie_host_init() needs to be called, so set it global. The dev function parameter is removed, as it isn't used.

PCI: cadence: Extract link setup sequence from cdns_pcie_host_setup()

2024-09-03T18:27:12Z

The function cdns_pcie_host_setup() mixes probe structure and link setup. The link setup must be done during the resume sequence. So extract it from cdns_pcie_host_setup() and create a dedicated function.
