2024-11-01regulator: rk808: Add apply_bit for BUCK3 on RK809Mikhail Rudenko
Currently, RK809's BUCK3 regulator is modelled in the driver as a configurable regulator with 0.5-2.4V voltage range. But the voltage setting is not actually applied, because when bit 6 of PMIC_POWER_CONFIG register is set to 0 (default), BUCK3 output voltage is determined by the external feedback resistor. Fix this, by setting bit 6 when voltage selection is set. Existing users which do not specify voltage constraints in their device trees will not be affected by this change, since no voltage setting is applied in those cases, and bit 6 is not enabled.

2024-10-31net: enetc: set MAC address to the VF net_deviceWei Fang
The MAC address of VF can be configured through the mailbox mechanism of ENETC, but the previous implementation forgot to set the MAC address in net_device, resulting in the SMAC of the sent frames still being the old MAC address. Since the MAC address in the hardware has been changed, Rx cannot receive frames with the DMAC address as the new MAC address. The most obvious phenomenon is that after changing the MAC address, we can see that the MAC address of eno0vf0 has not changed through the "ifconfig eno0vf0" command and the IP address cannot be obtained . root@ls1028ardb:~# ifconfig eno0vf0 down root@ls1028ardb:~# ifconfig eno0vf0 hw ether 00:04:9f:3a:4d:56 up root@ls1028ardb:~# ifconfig eno0vf0 eno0vf0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 ether 66:36:2c:3b:87:76 txqueuelen 1000 (Ethernet) RX packets 794 bytes 69239 (69.2 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 11 bytes 2226 (2.2 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 Fixes: beb74ac878c8 ("enetc: Add vf to pf messaging support") Signed-off-by: Wei Fang <wei.fang@nxp.com> Reviewed-by: Vladimir Oltean <vladimir.oltean@nxp.com> Reviewed-by: Claudiu Manoil <claudiu.manoil@nxp.com> Link: https://patch.msgid.link/20241029090406.841836-1-wei.fang@nxp.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

git://git.kernel.org/pub/scm/linux/kernel/git/ath/ath ath.git patches for v6.13 This development cycle featured phase 1 of patches to ath12k to support the new 802.11be MLO feature, along with other ath12k feature patches. In older drivers, support for some additional devices were added. And there was the usual set of bug fixes and cleanups across most drivers. Per-driver highlights: ath12k * Switch to using wiphy_lock() and remove ar->conf_mutex * Convert struct ath12k_sta::update_wk to use struct wiphy_work * Add phase 1 of 802.11be MLO support * Add firmware coredump collection support * Add debugfs support for a multitude of statistics * Fix host representation of multiple hal_rx structs * Fix use-after-free in ath12k_dp_cc_cleanup() * Skip Rx TID cleanup for self peer * Fix warning and crash when unloading in a VM * Convert CE interrupt handling from tasklet to BH workqueue * Fix A-MSDU indication in monitor mode ath11k * Fix double free issue during SRNG deinit * Enable firmware diagnostic events for WCN6750 * Fix CE offset address calculation for WCN6750 during SSR * Fix stack frame size warning in ath11k_vif_wow_set_wakeups() * Document the inputs for ath11k on WCN6855 ath10k * Fix multiple stack frame size warnings * Fix invalid VHT parameters in supported_vht_mcs_rate_nss* structs * Avoid NULL pointer error during SDIO remove ath5k * Add support for Arcadyan ARV45XX AR2417 & Gigaset SX76[23] AR241[34]A
2024-10-31drm/xe: Don't short circuit TDR on jobs not startedMatthew Brost
Short circuiting TDR on jobs not started is an optimization which is not required. On LNL we are facing an issue where jobs do not get scheduled by the GuC if it misses a GGTT page update. When this occurs let the TDR fire, toggle the scheduling which may get the job unstuck, and print a warning message. If the TDR fires twice on job that hasn't started, timeout the job. v2: - Add warning message (Paulo) - Add fixes tag (Paulo) - Timeout job which hasn't started after TDR firing twice v3: - Include local change v4: - Short circuit check_timeout on job not started - use warn level rather than notice (Paulo) Fixes: 7ddb9403dd74 ("drm/xe: Sample ctx timestamp to determine if jobs have timed out") Cc: stable@vger.kernel.org Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241025214330.2010521-2-matthew.brost@intel.com Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> (cherry picked from commit 35d25a4a0012e690ef0cc4c5440231176db595cc) Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>
2024-10-31drm/xe: Add mmio read before GGTT invalidateMatthew Brost
On LNL without a mmio read before a GGTT invalidate the GuC can incorrectly read the GGTT scratch page upon next access leading to jobs not getting scheduled. A mmio read before a GGTT invalidate seems to fix this. Since a GGTT invalidate is not a hot code path, blindly do a mmio read before each GGTT invalidate.

Fix an issue detected by the Smatch tool: drivers/gpio/gpiolib-swnode.c:78 swnode_find_gpio() error: uninitialized symbol 'ret'. The issue occurs because the 'ret' variable may be used without initialization if the for_each_gpio_property_name loop does not run. This could lead to returning an undefined value, causing unpredictable behavior. Initialize 'ret' to 0 before the loop to ensure the function returns an error code if no properties are parsed, maintaining proper error handling.

Note that dev_err_probe() has advantages even if the error code is not EPROBE_DEFER, such as the symbolic output of the error code. Therefore, it should generally be preferred over dev_err().

This patch modifies the implementation of debugfs: When the user process stops unexpectedly, not all data of the file system is read. In this case, the save_buf pointer is not released. When the user process is called next time, save_buf is used to copy the cached data to the user space. As a result, the queried data is inconsistent. To solve this problem, determine whether the function is invoked for the first time based on the value of *ppos. If *ppos is 0, obtain the actual data.
