2020-08-31phy: socionext: Add UniPhier AHCI PHY driver supportKunihiko Hayashi3-0/+332
Add a driver for PHY interface built into ahci controller implemented in UniPhier SoCs. This supports PXs2 and PXs3 SoCs.

2020-03-20phy: uniphier-pcie: Add SoC-dependent phy-mode function supportKunihiko Hayashi1-7/+10
Since this phy is shared by multiple devices including USB and PCIe, it is necessary to determine which device use this phy. This patch adds SoC-dependent functions to determine a device using this phy. When there is 'socionext,syscon' property in the pcie-phy node, the driver calls SoC-dependt function instead of checking .has_syscon in SoC-dependent data. The function configures the system controller to use phy for PCIe. Signed-off-by: Kunihiko Hayashi <hayashi.kunihiko@socionext.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
2020-03-20phy: uniphier-pcie: Add legacy SoC support for Pro5Kunihiko Hayashi1-11/+72
Add legacy SoC support that needs to manage gio clock and reset and to skip setting unimplemented phy parameters. This supports Pro5. This specifies only 1 port use because Pro5 doesn't set it in the power-on sequence.

2020-03-20phy: uniphier-usb3hs: Change Rx sync mode to avoid communication failureKunihiko Hayashi1-4/+16
In case of using default parameters, communication failure might occur in rare cases. This sets Rx sync mode parameter to avoid the issue. Signed-off-by: Kunihiko Hayashi <hayashi.kunihiko@socionext.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

Add legacy SoC support that needs to manage gio clock and reset. This supports Pro5. Signed-off-by: Kunihiko Hayashi <hayashi.kunihiko@socionext.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
2020-03-20phy: uniphier-usb3ss: Add Pro5 supportKunihiko Hayashi1-0/+4
Pro5 SoC has same scheme of USB3 ss-phy as Pro4, so the data for Pro5 is equivalent to Pro4. Signed-off-by: Kunihiko Hayashi <hayashi.kunihiko@socionext.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

2018-11-12phy: uniphier-pcie: Depend on HAS_IOMEMKunihiko Hayashi1-1/+2
The driver uses devm_ioremap_resource() which is only available when CONFIG_HAS_IOMEM is set, so the driver depends on this option. Signed-off-by: Kunihiko Hayashi <hayashi.kunihiko@socionext.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
