phy: usb: add support for bcm74110

2025-04-11T07:21:13+00:00

bcm74110 adds a freerun utmi/ref clock that saves further power during
suspend states. A tune is also necessary to pass USB compliance test.

phy: usb: Toggle the PHY power during init

2024-12-04T14:15:35+00:00

When bringing up the PHY, it might be in a bad state if left powered.
One case is we lose the PLL lock if the PLL is gated while the PHY
is powered. Toggle the PHY power so we can start from a known state.

phy: bcm-ns-usb2: drop support for old binding variant

2024-10-21T18:26:16+00:00

The old binding was incorrectly designed and ended up being deprecated 3
years ago. Finally it has been dropped so relevant code it not needed
anymore.

phy: Switch back to struct platform_driver::remove()

2024-10-17T15:03:03+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/phy/ to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

While touching these files, make indention of the struct initializer
consistent in several files.

phy: usb: disable COMMONONN for dual mode

2024-10-11T08:26:25+00:00

The COMMONONN bit suspends the phy when the port is put into a suspend
state. However when the phy is shared between host and device in dual
mode, this no longer works cleanly as there is no synchronization between
the two.

phy: usb: update Broadcom driver table to use designated initializers

2024-10-07T06:15:34+00:00

The Broadcom USB PHY driver contains a lookup table
(`reg_bits_map_tables`) to resolve register bitmaps unique to certain
versions of the USB PHY as found in various Broadcom chip families.
Historically, this table was just kept carefully in sync with the
"selector" enum every time the latter changed to ensure consistency.
However, a recent commit [1] introduced two new enumerators but did not
adjust the array for BCM4908, thus breaking the xHCI controller (and
boot process) on this platform and revealing the fragility of this
approach.

Since these arrays are a little sparse (many elements are zero) and the
position of the array elements is significant only insofar as they agree
with the enumerators, designated initializers are a better fit than
positional initializers here. Convert this table accordingly.

phy: usb: Fix missing elements in BCM4908 USB init array

2024-10-07T06:13:46+00:00

The Broadcom USB PHY driver contains a lookup table
(`reg_bits_map_tables`) to resolve register bitmaps unique to certain
versions of the USB PHY as found in various Broadcom chip families. A
recent commit (see 'fixes' tag) introduced two new elements to each chip
family in this table -- except for one: BCM4908. This resulted in the
xHCI controller not being initialized correctly, causing a panic on
boot.

The next patch will update this table to use designated initializers in
order to prevent this from happening again. For now, just add back the
missing array elements to resolve the regression.
