2024-09-11net: ethernet: oa_tc6: implement software resetParthiban Veerasooran
Reset complete bit is set when the MAC-PHY reset completes and ready for configuration. Additionally reset complete bit in the STS0 register has to be written by one upon reset complete to clear the interrupt.

2024-09-11net: ethernet: oa_tc6: implement register read operationParthiban Veerasooran
Implement register read operation according to the control communication specified in the OPEN Alliance 10BASE-T1x MACPHY Serial Interface document. Control read commands are used by the SPI host to read registers within the MAC-PHY. Each control read commands are composed of a 32 bits control command header. The MAC-PHY ignores all data from the SPI host following the control header for the remainder of the control read command. Control read commands can read either a single register or multiple consecutive registers. When multiple consecutive registers are read, the address is automatically post-incremented by the MAC-PHY. Reading any unimplemented or undefined registers shall return zero.

2024-09-11net: ethernet: oa_tc6: implement register write operationParthiban Veerasooran
Implement register write operation according to the control communication specified in the OPEN Alliance 10BASE-T1x MACPHY Serial Interface document. Control write commands are used by the SPI host to write registers within the MAC-PHY. Each control write commands are composed of a 32 bits control command header followed by register write data. The MAC-PHY ignores the final 32 bits of data from the SPI host at the end of the control write command. The write command and data is also echoed from the MAC-PHY back to the SPI host to enable the SPI host to identify which register write failed in the case of any bus errors. Control write commands can write either a single register or multiple consecutive registers. When multiple consecutive registers are written, the address is automatically post-incremented by the MAC-PHY. Writing to any unimplemented or undefined registers shall be ignored and yield no effect.

Part II does the following: * adds generic libeth Tx completion routines; * converts idpf to use generic libeth Tx comp routines; * fixes Tx queue timeouts and robustifies Tx completion in general; * fixes Tx event/descriptor flushes (writebacks). Most idpf patches again remove more lines than adds. Generic Tx completion helpers and structs are needed as libeth_xdp (Ch. III) makes use of them. WB_ON_ITR is needed since XDPSQs don't want to work without it at all. Tx queue timeouts fixes are needed since without them, it's way easier to catch a Tx timeout event when WB_ON_ITR is enabled. * '200GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: idpf: enable WB_ON_ITR idpf: fix netdev Tx queue stop/wake idpf: refactor Tx completion routines netdevice: add netdev_tx_reset_subqueue() shorthand idpf: convert to libeth Tx buffer completion libeth: add Tx buffer completion helpers ==================== Link: https://patch.msgid.link/20240909205323.3110312-1-anthony.l.nguyen@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2024-09-11iommufd: Avoid duplicated __iommu_group_set_core_domain() callYi Liu
For the fault-capable hwpts, the iommufd_hwpt_detach_device() calls both iommufd_fault_domain_detach_dev() and iommu_detach_group(). This would have duplicated __iommu_group_set_core_domain() call since both functions call it in the end. This looks no harm as the __iommu_group_set_core_domain() returns if the new domain equals to the existing one. But it makes sense to avoid such duplicated calls in caller side.

2024-09-11net: dsa: felix: ignore pending status of TAS module when it's disabledXiaoliang Yang
The TAS module could not be configured when it's running in pending status. We need disable the module and configure it again. However, the pending status is not cleared after the module disabled. TC taprio set will always return busy even it's disabled. For example, a user uses tc-taprio to configure Qbv and a future basetime. The TAS module will run in a pending status. There is no way to reconfigure Qbv, it always returns busy. Actually the TAS module can be reconfigured when it's disabled. So it doesn't need to check the pending status if the TAS module is disabled. After the patch, user can delete the tc taprio configuration to disable Qbv and reconfigure it again.

The V3(s) will detect a valid external low frequency clock and if it is not present will automatically switch to the internal one. This might hide bugs and (hardware) configuration errors. It's even worse because the internal RTC runs significantly slower (32.000Hz vs 32.768Hz). Fortunately for us, the V3(s) has an (undocumented) bypass of this switching and the driver already supports it by setting the .has_auto_swt flag.

2024-09-11i2c: xiic: Try re-initialization on bus busy timeoutRobert Hancock
In the event that the I2C bus was powered down when the I2C controller driver loads, or some spurious pulses occur on the I2C bus, it's possible that the controller detects a spurious I2C "start" condition. In this situation it may continue to report the bus is busy indefinitely and block the controller from working. The "single-master" DT flag can be specified to disable bus busy checks entirely, but this may not be safe to use in situations where other I2C masters may potentially exist. In the event that the controller reports "bus busy" for too long when starting a transaction, we can try reinitializing the controller to see if the busy condition clears.

2024-09-11i2c: xiic: Wait for TX empty to avoid missed TX NAKsRobert Hancock
Frequently an I2C write will be followed by a read, such as a register address write followed by a read of the register value. In this driver, when the TX FIFO half empty interrupt was raised and it was determined that there was enough space in the TX FIFO to send the following read command, it would do so without waiting for the TX FIFO to actually empty. Unfortunately it appears that in some cases this can result in a NAK that was raised by the target device on the write, such as due to an unsupported register address, being ignored and the subsequent read being done anyway. This can potentially put the I2C bus into an invalid state and/or result in invalid read data being processed. To avoid this, once a message has been fully written to the TX FIFO, wait for the TX FIFO empty interrupt before moving on to the next message, to ensure NAKs are handled properly.

2024-09-11minmax: reduce min/max macro expansion in atomisp driverLorenzo Stoakes
Avoid unnecessary nested min()/max() which results in egregious macro expansion. Use clamp_t() as this introduces the least possible expansion, and turn the {s,u}DIGIT_FITTING() macros into inline functions to avoid the nested expansion. This resolves an issue with slackware 15.0 32-bit compilation as reported by Richard Narron. Presumably the min/max fixups would be difficult to backport, this patch should be easier and fix's Richard's problem in 5.15.

2024-09-11fbdev: pxafb: Fix possible use after free in pxafb_task()Kaixin Wang
In the pxafb_probe function, it calls the pxafb_init_fbinfo function, after which &fbi->task is associated with pxafb_task. Moreover, within this pxafb_init_fbinfo function, the pxafb_blank function within the &pxafb_ops struct is capable of scheduling work. If we remove the module which will call pxafb_remove to make cleanup, it will call unregister_framebuffer function which can call do_unregister_framebuffer to free fbi->fb through put_fb_info(fb_info), while the work mentioned above will be used. The sequence of operations that may lead to a UAF bug is as follows: CPU0 CPU1 | pxafb_task pxafb_remove | unregister_framebuffer(info) | do_unregister_framebuffer(fb_info) | put_fb_info(fb_info) | // free fbi->fb | set_ctrlr_state(fbi, state) | __pxafb_lcd_power(fbi, 0) | fbi->lcd_power(on, &fbi->fb.var) | //use fbi->fb Fix it by ensuring that the work is canceled before proceeding with the cleanup in pxafb_remove.

The function name is ambiguous because it returns an intermediate value for calculating maximum frequency rather than the CPPC 'Highest Perf' register. Rename the function to clarify its use and allow the function to return errors. Adjust the consumer in acpi-cpufreq to catch errors. Reviewed-by: Gautham R.

2024-09-11drm/amd/display: Add all planes on CRTC to state for overlay cursorLeo Li
[Why] DC has a special commit path for native cursor, which use the built-in cursor pipe within DCN planes. This update path does not require all enabled planes to be added to the list of surface updates sent to DC. This is not the case for overlay cursor; it uses the same path as MPO commits. This update path requires all enabled planes to be added to the list of surface updates sent to DC. Otherwise, DC will disable planes not inside the list. [How] If overlay cursor is needed, add all planes on the same CRTC as this cursor to the atomic state. This is already done for non-cursor planes (MPO), just before the added lines.

2024-09-11regulator: core: fix the broken behavior of regulator_dev_lookup()Wei Fang
The behavior of regulator_dev_lookup() for non-DT way has been broken since the commit b8c325545714 ("regulator: Move OF-specific regulator lookup code to of_regulator.c"). Before the commit, of_get_regulator() was used to get the regulator, which returns NULL if the regulator is not found. So the regulator will be looked up through regulator_lookup_by_name() if no matching regulator is found in regulator_map_list. However, currently, of_regulator_dev_lookup() is used to instead of of_get_regulator(), but the variable 'r' is set to ERR_PTR(-ENODEV) instead of NULL if the regulator is not found. In this case, if no regulator is found in regulator_map_list, the variable 'r' is still ERR_PTR(-ENODEV), So regulator_dev_lookup() returns the value of 'r' directly instead of continuing to look up the regulator through regulator_lookup_by_name().
