2021-12-24phy: uniphier-usb3ss: fix unintended writing zeros to PHY registerRyuta NAKANISHI1-4/+6
Similar to commit 4a90bbb478db ("phy: uniphier-pcie: Fix updating phy parameters"), in function uniphier_u3ssphy_set_param(), unintentionally write zeros to other fields when writing PHY registers.

2021-11-23phy: uniphier-ahci: Add support for Pro4 SoCKunihiko Hayashi2-5/+198
Add support for PHY interface built into ahci controller implemented in UniPhier Pro4 SoC. Pro4 SoC distinguishes it from other SoCs as "legacy" SoC, which has GIO clock line. And Pro4 AHCI-PHY needs to control additional reset lines ("pm", "tx", and "rx").

2021-06-21phy: uniphier-pcie: Fix updating phy parametersKunihiko Hayashi1-4/+7
The current driver uses a value from register TEST_O as the original value for register TEST_I, though, the value is overwritten by "param", so there is a bug that the original value isn't no longer used. The value of TEST_O[7:0] should be masked with "mask", replaced with "param", and placed in the bitfield TESTI_DAT_MASK as new TEST_I value.

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.
