2023-05-17can: kvaser_pciefd: Do not send EFLUSH command on TFD interruptJimmy Assarsson
Under certain circumstances we send two EFLUSH commands, resulting in two EFLUSH ack packets, while only expecting a single EFLUSH ack. This can cause the driver Tx flush completion to get out of sync. To avoid this problem, don't enable the "Transmit buffer flush done" (TFD) interrupt and remove the code handling it. Now we only send EFLUSH command after receiving status packet with "Init detected" (IDET) bit set.

stp_set_state() should actually allow receiving BPDU while in LEARNING mode which is not the case. Additionally, the BLOCKEN bit does not actually forbid sending forwarded frames from that port. To fix this, add a5psw_port_tx_enable() function which allows to disable TX. However, while its name suggest that TX is totally disabled, it is not and can still allow to send BPDUs even if disabled. This can be done by using forced forwarding with the switch tagging mechanism but keeping "filtering" disabled (which is already the case in the rzn1-a5sw tag driver).

In the (unlikely) event that pm_runtime_get() (disguised as pm_runtime_resume_and_get()) fails, the remove callback returned an error early. The problem with this is that the driver core ignores the error value and continues removing the device. This results in a resource leak. Worse the devm allocated resources are freed and so if a callback of the driver is called later the register mapping is already gone which probably results in a crash.

2023-05-09net: stmmac: Initialize MAC_ONEUS_TIC_COUNTER registerMarek Vasut
Initialize MAC_ONEUS_TIC_COUNTER register with correct value derived from CSR clock, otherwise EEE is unstable on at least NXP i.MX8M Plus and Micrel KSZ9131RNX PHY, to the point where not even ARP request can be sent out. i.MX 8M Plus Applications Processor Reference Manual, Rev. 1, 06/2021 11.7.6.1.34 One-microsecond Reference Timer (MAC_ONEUS_TIC_COUNTER) defines this register as: " This register controls the generation of the Reference time (1 microsecond tic) for all the LPI timers. This timer has to be programmed by the software initially. ... The application must program this counter so that the number of clock cycles of CSR clock is 1us. (Subtract 1 from the value before programming). For example if the CSR clock is 100MHz then this field needs to be programmed to value 100 - 1 = 99 (which is 0x63). This is required to generate the 1US events that are used to update some of the EEE related counters. " The reset value is 0x63 on i.MX8M Plus, which means expected CSR clock are 100 MHz. However, the i.MX8M Plus "enet_qos_root_clk" are 266 MHz instead, which means the LPI timers reach their count much sooner on this platform. This is visible using a scope by monitoring e.g. exit from LPI mode on TX_CTL line from MAC to PHY. This should take 30us per STMMAC_DEFAULT_TWT_LS setting, during which the TX_CTL line transitions from tristate to low, and 30 us later from low to high. On i.MX8M Plus, this transition takes 11 us, which matches the 30us * 100/266 formula for misconfigured MAC_ONEUS_TIC_COUNTER register. Configure MAC_ONEUS_TIC_COUNTER based on CSR clock, so that the LPI timers have correct 1us reference. This then fixes EEE on i.MX8M Plus with Micrel KSZ9131RNX PHY.

Currently when the uncore_write() returns error, it is silently ignored. Return error to user space when uncore_write() fails.

2023-05-08media: nxp: imx8-isi: fix buiding on 32-bitArnd Bergmann
The #if check is wrong, leading to a build failure: drivers/media/platform/nxp/imx8-isi/imx8-isi-hw.c: In function 'mxc_isi_channel_set_inbuf': drivers/media/platform/nxp/imx8-isi/imx8-isi-hw.c:33:5: error: "CONFIG_ARCH_DMA_ADDR_T_64BIT" is not defined, evaluates to 0 [-Werror=undef] 33 | #if CONFIG_ARCH_DMA_ADDR_T_64BIT | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ This could just be an #ifdef, but it seems nicer to just remove the check entirely. Apparently the only reason for the #ifdef is to avoid another warning: drivers/media/platform/nxp/imx8-isi/imx8-isi-hw.c:55:24: error: right shift count >= width of type [-Werror=shift-count-overflow] But this is best avoided by using the lower_32_bits()/upper_32_bits() helpers.

2023-05-08platform/x86: intel_scu_pcidrv: Add back PCI ID for MedfieldJulian Winkler
This id was removed in commit b47018a778c1 ("platform/x86: intel_scu_ipc: Remove Lincroft support"), saying it is only used on Moorestown, but apparently the same id is also used on Medfield. Tested on the Medfield based Motorola RAZR i smartphone.

2023-05-08media: platform: mtk-mdp3: work around unused-variable warningArnd Bergmann
When CONFIG_OF is disabled, the 'data' variable is not used at all because of_match_node() turns into a dummy macro: drivers/media/platform/mediatek/mdp3/mtk-mdp3-comp.c: In function 'mdp_comp_sub_create': drivers/media/platform/mediatek/mdp3/mtk-mdp3-comp.c:1038:36: error: unused variable 'data' [-Werror=unused-variable] 1038 | const struct mtk_mdp_driver_data *data = mdp->mdp_data; | ^~~~ Remove the variable again by moving the pointer dereference into the of_match_node call.

gcc warns about some functions being unused when CONFIG_PM_SLEEP is disabled: drivers/media/platform/nxp/imx8-isi/imx8-isi-core.c:328:12: error: 'mxc_isi_pm_resume' defined but not used [-Werror=unused-function] 328 | static int mxc_isi_pm_resume(struct device *dev) | ^~~~~~~~~~~~~~~~~ drivers/media/platform/nxp/imx8-isi/imx8-isi-core.c:314:12: error: 'mxc_isi_pm_suspend' defined but not used [-Werror=unused-function] 314 | static int mxc_isi_pm_suspend(struct device *dev) | ^~~~~~~~~~~~~~~~~~ Use the modern SYSTEM_SLEEP_PM_OPS()/RUNTIME_PM_OPS() helpers in place of the old SET_SYSTEM_SLEEP_PM_OPS()/SET_RUNTIME_PM_OPS() ones. By convention, use pm_ptr() to guard the reference to the operations. This makes no difference as long as the driver requires CONFIG_PM, but is what users of SET_RUNTIME_PM_OPS() are supposed to do.
