The connector child node of the TUSB320 device might be linked with a dual-role capable USB controller. Add driver support for detecting a usb_role_switch and setting its state in the typec interrupt handler. This follows similar practice in other drivers in the typec subsystem, which this extcon driver can opt-in to.

2023-05-29extcon: usbc-tusb320: add accessory detection supportAlvin Šipraga
The TUSB320 can detect the following types of accessory: - Audio Accessory - Audio Accessory with charge-thru - Debug Accessory (DFP) - Debug Accessory (UFP) Moreover, the typec subsystem can be informed of this through the typec_set_mode() function. The information will be propagated to any linked typec muxes. Add the necessary support to the driver. Note that for the Debug Accessory modes, an educated guess was made that for the USB data role, DFP implies HOST and UFP implies DEVICE. But this might want to be made configurable at a later date.

2023-05-29extcon: qcom-spmi: Switch to platform_get_irq_byname_optionalBryan O'Donoghue
Valid configurations for the extcon interrupt declarations are - usb_id - usb_vbus - (usb_id | usb_vbus) In the case of a standalone usb_id or usb_vbus failure to find one of the interrupts shouldn't generate a warning message. A warning is already in place if both IRQs are missing. Switch to using platform_get_irq_byname_optional() in order to facilitate this behaviour.

2023-05-29dt-bindings: pm8941-misc: Fix usb_id and usb_vbus definitionsBryan O'Donoghue
dts validation is throwing an error for me on 8916 and 8939 with extcon@1300. In that case we have usb_vbus but not usb_id. It wasn't immediately obvious if there was a valid use-case for the existing code for usb_id in isolation, however discussing further, we concluded that usb_id, usb_vbus or (usb_id | usb_vbus) are valid combinations as an external IC may be responsible for usb_id or usb_vbus. Expand the definition with anyOf to capture the three different valid modes.

2023-05-29extcon: usbc-tusb320: Unregister typec port on driver removalAlvin Šipraga
The driver can register a typec port if suitable firmware properties are present. But if the driver is removed through sysfs unbind, rmmod or similar, then it does not clean up after itself and the typec port device remains registered. This can be seen in sysfs, where stale typec ports get left over in /sys/class/typec. In order to fix this we have to add an i2c_driver remove function and call typec_unregister_port(), which is a no-op in the case where no typec port is created and the pointer remains NULL. In the process we should also put the fwnode_handle when the typec port isn't registered anymore, including if an error occurs during probe. The typec subsystem does not increase or decrease the reference counter for us, so we track it in the driver's private data. Note that the conditional check on TYPEC_PWR_MODE_PD was removed in the probe path because a call to tusb320_set_adv_pwr_mode() will perform an even more robust validation immediately after, hence there is no functional change here.

When media is not ready do not assume that the capacity information from the identify command is valid, i.e. ->total_bytes ->partition_align_bytes ->{volatile,persistent}_only_bytes. Explicitly zero out the capacity resources and exit early.

2023-05-26x86: re-introduce support for ERMS copies for user space accessesLinus Torvalds
I tried to streamline our user memory copy code fairly aggressively in commit adfcf4231b8c ("x86: don't use REP_GOOD or ERMS for user memory copies"), in order to then be able to clean up the code and inline the modern FSRM case in commit 577e6a7fd50d ("x86: inline the 'rep movs' in user copies for the FSRM case"). We had reports [1] of that causing regressions earlier with blogbench, but that turned out to be a horrible benchmark for that case, and not a sufficient reason for re-instating "rep movsb" on older machines. However, now Eric Dumazet reported [2] a regression in performance that seems to be a rather more real benchmark, where due to the removal of "rep movs" a TCP stream over a 100Gbps network no longer reaches line speed. And it turns out that with the simplified the calling convention for the non-FSRM case in commit 427fda2c8a49 ("x86: improve on the non-rep 'copy_user' function"), re-introducing the ERMS case is actually fairly simple. Of course, that "fairly simple" is glossing over several missteps due to having to fight our assembler alternative code. This code really wanted to rewrite a conditional branch to have two different targets, but that made objtool sufficiently unhappy that this instead just ended up doing a choice between "jump to the unrolled loop, or use 'rep movsb' directly". Let's see if somebody finds a case where the kernel memory copies also care (see commit 68674f94ffc9: "x86: don't use REP_GOOD or ERMS for small memory copies"). But Eric does argue that the user copies are special because networking tries to copy up to 32KB at a time, if order-3 pages allocations are possible. In-kernel memory copies are typically small, unless they are the special "copy pages at a time" kind that still use "rep movs".

FF-A core probe failure on systems with v1.0 firmware as the new partition info get count flag is used unconditionally 3. Failure to register more than one logical partition or service within the same physical partition as the device name contains only VM ID which will be same for all but each will have unique UUID. 4.
