[PATCH v3 3/5] phy: renesas: rcar-gen3-usb2: Lock around hardware registers and driver data

by Claudiu

From: Claudiu Beznea <claudiu.beznea.uj(a)bp.renesas.com> The phy-rcar-gen3-usb2 driver exposes four individual PHYs that are requested and configured by PHY users. The struct phy_ops APIs access the same set of registers to configure all PHYs. Additionally, PHY settings can be modified through sysfs or an IRQ handler. While some struct phy_ops APIs are protected by a driver-wide mutex, others rely on individual PHY-specific mutexes. This approach can lead to various issues, including: 1/ the IRQ handler may interrupt PHY settings in progress, racing with hardware configuration protected by a mutex lock 2/ due to msleep(20) in rcar_gen3_init_otg(), while a configuration thread suspends to wait for the delay, another thread may try to configure another PHY (with phy_init() + phy_power_on()); re-running the phy_init() goes to the exact same configuration code, re-running the same hardware configuration on the same set of registers (and bits) which might impact the result of the msleep for the 1st configuring thread 3/ sysfs can configure the hardware (though role_store()) and it can still race with the phy_init()/phy_power_on() APIs calling into the drivers struct phy_ops To address these issues, add a spinlock to protect hardware register access and driver private data structures (e.g., calls to rcar_gen3_is_any_rphy_initialized()). Checking driver-specific data remains necessary as all PHY instances share common settings. With this change, the existing mutex protection is removed and the cleanup.h helpers are used. While at it, to keep the code simpler, do not skip regulator_enable()/regulator_disable() APIs in rcar_gen3_phy_usb2_power_on()/rcar_gen3_phy_usb2_power_off() as the regulators enable/disable operations are reference counted anyway.

[PATCH v3 1/5] phy: renesas: rcar-gen3-usb2: Fix role detection on unbind/bind

by Claudiu

From: Claudiu Beznea <claudiu.beznea.uj(a)bp.renesas.com> It has been observed on the Renesas RZ/G3S SoC that unbinding and binding the PHY driver leads to role autodetection failures. This issue occurs when PHY 3 is the first initialized PHY. PHY 3 does not have an interrupt associated with the USB2_INT_ENABLE register (as rcar_gen3_int_enable[3] = 0). As a result, rcar_gen3_init_otg() is called to initialize OTG without enabling PHY interrupts. To resolve this, add rcar_gen3_is_any_otg_rphy_initialized() and call it in role_store(), role_show(), and rcar_gen3_init_otg(). At the same time, rcar_gen3_init_otg() is only called when initialization for a PHY with interrupt bits is in progress. As a result, the struct rcar_gen3_phy::otg_initialized is no longer needed.

[PATCH v2 6/7] media: mt9m114: Fix deadlock in get_frame_interval/set_frame_interval

by Mathis Foerst

Getting / Setting the frame interval using the V4L2 subdev pad ops get_frame_interval/set_frame_interval causes a deadlock, as the subdev state is locked in the [1] but also in the driver itself. In [2] it's described that the caller is responsible to acquire and release the lock in this case. Therefore, acquiring the lock in the driver is wrong. Remove the lock acquisitions/releases from mt9m114_ifp_get_frame_interval() and mt9m114_ifp_set_frame_interval().

[tip: x86/urgent] x86/cacheinfo: Validate CPUID leaf 0x2 EDX output

by tip-bot2 for Ahmed S. Darwish

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: 8177c6bedb7013cf736137da586cf783922309dd Gitweb: https://git.kernel.org/tip/8177c6bedb7013cf736137da586cf783922309dd Author: Ahmed S. Darwish <darwi(a)linutronix.de> AuthorDate: Tue, 04 Mar 2025 09:51:12 +01:00 Committer: Ingo Molnar <mingo(a)kernel.org> CommitterDate: Tue, 04 Mar 2025 09:59:14 +01:00 x86/cacheinfo: Validate CPUID leaf 0x2 EDX output CPUID leaf 0x2 emits one-byte descriptors in its four output registers EAX, EBX, ECX, and EDX. For these descriptors to be valid, the most significant bit (MSB) of each register must be clear. The historical Git commit: 019361a20f016 ("- pre6: Intel: start to add Pentium IV specific stuff (128-byte cacheline etc)...") introduced leaf 0x2 output parsing. It only validated the MSBs of EAX, EBX, and ECX, but left EDX unchecked. Validate EDX's most-significant bit. Signed-off-by: Ahmed S.

[PATCH V2 2/2] USB: serial: option: fix Telit Cinterion FE990A name

by Fabio Porcedda

The correct name for FE990 is FE990A so use it in order to avoid confusion with FE990B.
