2021-02-11spi: spi-mem: add spi_mem_dtr_supports_op()Pratyush Yadav
spi_mem_default_supports_op() rejects DTR ops by default to ensure that the controller drivers that haven't been updated with DTR support continue to reject them. It also makes sure that controllers that don't support DTR mode at all (which is most of them at the moment) also reject them. This means that controller drivers that want to support DTR mode can't use spi_mem_default_supports_op(). Driver authors have to roll their own supports_op() function and mimic the buswidth checks. See spi-cadence-quadspi.c for example. Or even worse, driver authors might skip it completely or get it wrong. Add spi_mem_dtr_supports_op(). It provides a basic sanity check for DTR ops and performs the buswidth requirement check. Move the logic for checking buswidth in spi_mem_default_supports_op() to a separate function so the logic is not repeated twice.

2021-02-11platform/x86: intel_scu_ipc: Increase virtual timeout from 3 to 5 secondsCasey Bowman
Increasing the virtual timeout time to account for scenarios that may require more time, like DisplayPort Multi-Stream Transport (DP MST), where the disconnect time can be extended longer than usual. The recommended timeout range is 5-10 seconds, of which we will take the lower bound.

Note that payload.len already contains the correct length after parsing via sshp_parse_frame(), so we can simply use that instead.

2021-02-11Merge series "Use clocks property in a device node" from Sameer Pujar ↵Mark Brown
<spujar@nvidia.com>: It is recommended to not specifiy clocks property in an endpoint subnode. This series moves clocks to device node. However after moving the clocks to device node, the audio playback or capture fails. The specified clock is not actually getting enabled and hence the failure is seen. There seems to be a bug in simple-card-utils.c where clock handle is not assigned when parsing clocks from device node. Fix the same and revert original change which actually added clocks property in endpoint subnode. Also update Jetson AGX Xavier DT where the usage is found.

2021-02-11selftests/bpf: Convert test_xdp_redirect.sh to bashBjörn Töpel
The test_xdp_redirect.sh script uses a bash feature, '&>'. On systems, e.g. Debian, where '/bin/sh' is dash, this will not work as expected. Use bash in the shebang to get the expected behavior. Further, using 'set -e' means that the error of a command cannot be captured without the command being executed with '&&' or '||'. Let us restructure the ping-commands, and use them as an if-expression, so that we can capture the return value. v4: Added missing Fixes:, and removed local variables. (Andrii) v3: Reintroduced /bin/bash, and kept 'set -e'. (Andrii) v2: Kept /bin/sh and removed bashisms.

Since sleepable programs are now executing under migrate_disable the per-cpu maps are safe to use. The map-in-map were ok to use in sleepable from the time sleepable progs were introduced. Note that non-preallocated maps are still not safe, since there is no rcu_read_lock yet in sleepable programs and dynamically allocated map elements are relying on rcu protection. The sleepable programs have rcu_read_lock_trace instead. That limitation will be addresses in the future.

By default the PCA9450 doesn't handle the assertion of the WDOG_B signal, but this is required to guarantee that things like software resets triggered by the watchdog work reliably. As we don't want to rely on the bootloader to enable this, we tell the PMIC to issue a cold reset in case the WDOG_B signal is asserted (WDOG_B_CFG = 10), just as the NXP U-Boot code does.

2021-02-11regulator: pca9450: Add SD_VSEL GPIO for LDO5Frieder Schrempf
LDO5 has two separate control registers. LDO5CTRL_L is used if the input signal SD_VSEL is low and LDO5CTRL_H if it is high. The current driver implementation only uses LDO5CTRL_H. To make this work on boards that have SD_VSEL connected to a GPIO, we add support for specifying an optional GPIO and setting it to high at probe time. In the future we might also want to add support for boards that have SD_VSEL set to a fixed low level. In this case we need to change the driver to be able to use the LDO5CTRL_L register.

2021-02-11locking/arch: Move qrwlock.h include after qspinlock.hWaiman Long
include/asm-generic/qrwlock.h was trying to get arch_spin_is_locked via asm-generic/qspinlock.h. However, this does not work because architectures might be using queued rwlocks but not queued spinlocks (csky), or because they might be defining their own queued_* macros before including asm/qspinlock.h. To fix this, ensure that asm/spinlock.h always includes qrwlock.h after defining arch_spin_is_locked (either directly for csky, or via asm/qspinlock.h for other architectures). The only inclusion elsewhere is in kernel/locking/qrwlock.c. That one is really unnecessary because the file is only compiled in SMP configurations (config QUEUED_RWLOCKS depends on SMP) and in that case linux/spinlock.h already includes asm/qrwlock.h if needed, via asm/spinlock.h.

2021-02-11staging: wfx: avoid defining array of flexible structMuhammad Usama Anjum
In this particular case, the struct element is already flexible struct. Thus struct element ie[] is ambiguous inside another struct. The members of struct element ie aren't being accessed in code anywhere. The data of u8 type is copied in it. So it has been changed to u8 ie[] to make the sparse happy and code simple. Warning from sparse: drivers/stagingwfx/hif_tx.c: note: in included file (through drivers/stagingwfx/data_tx.h, drivers/staging//wfx/wfx.h): drivers/staging//wfx/hif_api_cmd.h:103:26: warning: array of flexible structures Reviewed-by: Jérôme Pouiller <jerome.pouiller@silabs.com> Signed-off-by: Muhammad Usama Anjum <musamaanjum@gmail.com> Link: https://lore.kernel.org/r/20210211105026.GA45458@LEGION Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
