2022-10-31dt-bindings: cros-ec: Reorganize and enforce property availabilityStephen Boyd8-13/+30
Various properties in the cros-ec binding only apply to different compatible strings. For example, the interrupts and reg property are required for all cros-ec devices except for the rpmsg version. Add some conditions to update the availability of properties so that they can't be used with compatibles that don't support them. This reveals that many of the examples in bindings that use cros-ec were missing the interrupts property. Add the property to make those bindings whole again.

2022-10-28memory tier, sysfs: rename attribute "nodes" to "nodelist"Huang Ying1-2/+2
In sysfs, we use attribute name "cpumap" or "cpus" for cpu mask and "cpulist" or "cpus_list" for cpu list. For example, in my system, $ cat /sys/devices/system/node/node0/cpumap f,ffffffff $ cat /sys/devices/system/cpu/cpu2/topology/core_cpus 0,00100004 $ cat cat /sys/devices/system/node/node0/cpulist 0-35 $ cat /sys/devices/system/cpu/cpu2/topology/core_cpus_list 2,20 It looks reasonable to use "nodemap" for node mask and "nodelist" for node list. So, rename the attribute to follow the naming convention.

2022-10-28dt-bindings: memory-controllers: arm,pl353-smc: Extend to support ↵Rob Herring1-27/+53
'arm,pl354' SMC Add support for the Arm PL354 static memory controller to the existing Arm PL353 binding. Both are different configurations of the same IP with support for different types of memory interfaces. The 'arm,pl354' binding has already been in use upstream for a long time in Arm development boards. The existing users have only the controller without any child devices, so drop the required address properties (ranges, #address-cells, #size-cells). The schema for 'ranges' is too constrained as the order is not important and the PL354 has 8 chipselects (And the PL353 actually has up to 8 too). The clocks aren't really correct in either case. There's 1 bus clock and then a clock for each of the 2 memory interfaces.

sound-dai is a standard property whose type is already set to phandle-array by sound-dai.yaml, so there's no need to set it (and wrongly so for headset-codec) in this binding. What should be set however is the maximum number of items, which for headset-codec should be 1. Signed-off-by: Nícolas F. R. A.

2022-10-26s390/con3215: Drop console data printout when buffer fullThomas Richter1-0/+11
Using z/VM the 3270 terminal emulator also emulates an IBM 3215 console which outputs line by line. When the screen is full, the console enters the MORE... state and waits for the operator to confirm the data on the screen by pressing a clear key. If this does not happen in the default time frame (currently 50 seconds) the console enters the HOLDING state. It then waits another time frame (currently 10 seconds) before the output continues on the next screen. When the operator presses the clear key during these wait times, the output continues immediately. This may lead to a very long boot time when the console has to print many messages, also the system may hang because of the console's limited buffer space and the system waits for the console output to drain and finally to finish. This problem can only occur when a terminal emulator is actually connected to the 3215 console driver. If not z/VM simply drops console output. Remedy this rare situation and add a kernel boot command line parameter con3215_drop. It can be set to 0 (do not drop) or 1 (do drop) which is the default. This instructs the kernel drop console data when the console buffer is full. This speeds up the boot time considerable and also does not hang the system anymore. Add a sysfs attribute file for console IBM 3215 named con_drop. This allows for changing the behavior after the boot, for example when during interactive debugging a panic/crash is expected. Here is a test of the new behavior using the following test program: #/bin/bash declare -i cnt=4 mode=$(cat /sys/bus/ccw/drivers/3215/con_drop) [ $mode = yes ] && cnt=25 echo "cons_drop $(cat /sys/bus/ccw/drivers/3215/con_drop)" echo "vmcp term more 5 2" vmcp term more 5 2 echo "Run $cnt iterations of "'echo t > /proc/sysrq-trigger' for i in $(seq $cnt) do echo "$i. command 'echo t > /proc/sysrq-trigger' at $(date +%F,%T)" echo t > /proc/sysrq-trigger sleep 1 done echo "droptest done" > /dev/kmsg # Output with sysfs attribute con_drop set to 1: # ./droptest.sh cons_drop yes vmcp term more 5 2 Run 25 iterations of echo t > /proc/sysrq-trigger 1. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:09 2. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:10 3. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:11 4. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:12 5. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:13 6. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:14 7. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:15 8. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:16 9. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:17 10. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:18 11. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:19 12. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:20 13. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:21 14. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:22 15. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:23 16. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:24 17. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:25 18. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:26 19. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:27 20. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:28 21. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:29 22. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:30 23. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:31 24. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:32 25. command 'echo t > /proc/sysrq-trigger' at 2022-09-02,10:15:33 # There are no hangs anymore.

Function raw3125_putchar() just forwards its character for output to raw3215_write(). This moves tab to blank conversion to one function raw3215_write() which also does call raw3215_make_room() to wait for enough free buffer space. Function handle_write() loops over all its input and segments input into chunks of console buffer size (should the input be larger). Rework tab expansion handling logic to avoid code duplication.
