phy: uniphier-usb3ss: fix unintended writing zeros to PHY register

2022-01-27T08:19:39+00:00

[ Upstream commit 898c7a9ec81620125f2463714a0f4dea18ad6e54 ]

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.

phy: uniphier-pcie: Fix updating phy parameters

2021-07-14T14:53:46+00:00

[ Upstream commit 4a90bbb478dbf18ecdec9dcf8eb708e319d24264 ]

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.

phy: uniphier-usb3ss: Add Pro5 support

2020-04-23T08:36:33+00:00

[ Upstream commit 9376fa634afc207a3ce99e0957e04948c34d6510 ]

Pro5 SoC has same scheme of USB3 ss-phy as Pro4, so the data for Pro5 is
equivalent to Pro4.

phy: uniphier-pcie: Depend on HAS_IOMEM

2018-11-12T10:49:06+00:00

The driver uses devm_ioremap_resource() which is only available when
CONFIG_HAS_IOMEM is set, so the driver depends on this option.
