A SerDes PHY is optional, so if devm_phy_get() doesn't find one at all, that's fine. But if devm_phy_get() finds a PHY that doesn't have a driver yet, it returns -EPROBE_DEFER. In that case, defer probing the Keystone driver. We may be able to load it later after a PHY driver is loaded. [bhelgaas: changelog, check for -EPROBE_DEFER first] Signed-off-by: NShawn Lin <shawn.lin@rock-chips.com> Signed-off-by: NBjorn Helgaas <bhelgaas@google.com>

Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it. Thanks to Julia for her help!

Chained irq handlers usually set up handler data as well. We now have a function to set both under irq_desc->lock. Replace the two calls with one. Search and conversion was done with coccinelle.

Fix a race where a pending interrupt could be received and the handler called before the handler's data has been setup, by converting to irq_set_chained_handler_and_data().

All the DesignWare-based host drivers loop waiting for the link to come up, but they do it several ways that are needlessly different. Wait for the link to come up in a consistent style across all the DesignWare drivers. No functional change.

Replace a misspelled function name by %s and then __func__. The function name contains pcie, not pci as in the string. This was done using Coccinelle, including the use of Levenshtein distance, as proposed by Rasmus Villemoes.

K2E SoC has two PCI ports. The SATA controller is connected to second PCI port (port 1). To support multiple port handling in Keystone PCI driver, read the PCI device ID dynamically by iomap/read/unmap during probe and save it in driver's private data and update it in host init code. The PCI device ID field in the RC's config space is not filled by default by the hardware and has to be updated by the PCI driver by reading the same from the SoC register indicated by reg index #2 in DT bindings.

Keystone PCI hardware supports both RC and EP modes and devcfg register has bits to boot strap the device to either of these modes. It seems proper to add this functionality to the boot loader rather than in the driver as device will be operating in either mode, not both any time. Currently the driver supports only RC mode and hence register configuration in the driver is not needed and the driver can assume the hardware is in RC mode. Also update the DT documentation accordingly. Signed-off-by: NMurali Karicheri <m-karicheri2@ti.com> Signed-off-by: NBjorn Helgaas <bhelgaas@google.com> Acked-by: NArnd Bergmann <arnd@arndb.de>

The Keystone PCIe controller is based on v3.65 version of the Designware h/w. Main differences are: 1. No ATU support 2. Legacy and MSI IRQ functions are implemented in application register space 3. MSI interrupts are multiplexed over 8 IRQ lines to the Host side. All of the application register space handing code is organized into pci-keystone-dw.c and the functions are called from pci-keystone.c to implement PCI controller driver. Also add necessary DT documentation and update the MAINTAINERS file for the driver.
