phy: broadcom: ns-usb3: Fix Wvoid-pointer-to-enum-cast warning (again)

2026-01-23T10:18:41+00:00

[ Upstream commit fb21116099bbea1fc59efa9207e63c4be390ab72 ] "family" is an enum, thus cast of pointer on 64-bit compile test with clang W=1 causes: phy-bcm-ns-usb3.c:206:17: error: cast to smaller integer type 'enum bcm_ns_family' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast] This was already fixed in commit bd6e74a2f0a0 ("phy: broadcom: ns-usb3: fix Wvoid-pointer-to-enum-cast warning") but then got bad in commit 21bf6fc47a1e ("phy: Use device_get_match_data()"). Note that after various discussions the preferred cast is via "unsigned long", not "uintptr_t".

phy: broadcom: bcm63xx-usbh: fix section mismatches

commit 356d1924b9a6bc2164ce2bf1fad147b0c37ae085 upstream. Platform drivers can be probed after their init sections have been discarded (e.g. on probe deferral or manual rebind through sysfs) so the probe function and match table must not live in init.

phy: usb: Toggle the PHY power during init

2025-01-02T09:34:13+00:00

commit 0a92ea87bdd6f77ca4e17fe19649882cf5209edd upstream. 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: 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: 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.
