misc: rtsx: Add short delay after exit from ASPM

2020-05-22T11:27:38Z

DMA transfers to and from the SD card stall for 10 seconds and run into timeout on RTS5260 card readers after ASPM was enabled. Adding a short msleep after disabling ASPM fixes the issue on several Dell Precision 7530/7540 systems I tested. This function is only called when waking up after the chip went into power-save after not transferring data for a few seconds. The added msleep does therefore not change anything in data transfer speed or induce any excessive waiting while data transfers are running, or the chip is sleeping. Only the transition from sleep to active is affected.

misc: rtsx: Remove unnecessary rts5249_set_aspm(), rts5260_set_aspm()

2020-05-22T07:38:14Z

rts5249_set_aspm() and rts5260_set_aspm() do nothing more than the default rtsx_comm_set_aspm() does, so remove them and use the default. No functional change intended.

misc: rtsx: Simplify rtsx_comm_set_aspm()

2020-05-22T07:38:13Z

Simplify rtsx_comm_set_aspm() and remove the now-unused rtsx_pci_enable_aspm(). rtsx_pci_disable_aspm() is still used by rtsx_pci_init_hw(). Signed-off-by: Bjorn Helgaas Link: https://lore.kernel.org/r/20200521180545.1159896-6-helgaas@kernel.org Signed-off-by: Greg Kroah-Hartman

misc: rtsx: Use pcie_capability_clear_and_set_word() for PCI_EXP_LNKCTL

2020-05-22T07:38:13Z

Instead of using the driver-specific rtsx_pci_update_cfg_byte() to update the PCIe Link Control Register, use pcie_capability_clear_and_set_word() like the rest of the kernel does. This makes it easier to maintain ASPM across the PCI core and drivers. Remove the now-unused rtsx_pci_update_cfg_byte() and ASPM_MASK_NEG definitions. No functional change intended.

misc: rtsx: Use ASPM_MASK_NEG instead of hard-coded value

2020-05-22T07:38:12Z
