The VIN_DATA_PIN_GROUP() macro and vin_data{12,16,} unions are used to define multiple VIN data groups with different numbers of lanes, while referring to a single array of data pins, thus saving memory. However, the same feature would be useful for other resizable buses, like MMC, SDHI, QSPI, LCD, BSC, ... Rework the mechanism for generic use: - Use the new SH_PFC_PIN_GROUP_SUBSET() helper to remove the need for bus-specific unions, - Rename VIN_DATA_PIN_GROUP() to BUS_DATA_PIN_GROUP(), - Rename the macro parameters to better reflect their purposes, - Move the macro up, where it belongs. Update all individual pin control drivers for the above changes. Signed-off-by: -

It is fairly common for the pins in a pin group to be a subset of the pins in another pin group. Add a macro for defining a pin group that refers to a subset of an array of pins. This allows pin groups to share pin data, and thus save memory. Signed-off-by:

Reformat all macros that define structure initializers, to visually resemble structure definitions: - Move the opening curly brace to the previous line, - Move the closing curly brace to the first position, - Reduce indentation of the block to a single TAB, decreasing the need for line breaks, - Align backslashes for line continuation to the last TAB block where possible, Signed-off-by: -

Some instances of struct sh_pfc_soc_operations are called "<soc>_pfc_ops", others are called "<soc>_pinmux_ops" or just "pinmux_ops". Settle on the first variant, to avoid confusion with "struct pinmux_ops" in the pinctrl core, and to increase consistency. Signed-off-by:

The second video-in channel on RZ/G1C has only 12 data lanes, but the pin control driver uses the vin_data union, which is meant for 24 data lanes, thus wasting space. Fix this by using the vin_data12 union instead. This reduces kernel size by 96 bytes. Fixes: 50f3f2d7 ("pinctrl: sh-pfc: Reduce kernel size for narrow VIN channels") Signed-off-by:

Pull ftrace fix from Steven Rostedt: "Fix s390 breakage from sorting mcount tables. The latest merge of the tracing tree sorts the mcount table at build time. But s390 appears to do things differently (like always) and replaces the sorted table back to the original unsorted one. As the ftrace algorithm depends on it being sorted, bad things happen when it is not, and s390 experienced those bad things. Add a new config to tell the boot if the mcount table is sorted or not, and allow s390 to opt out of it" * tag 'trace-v5.17-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace: Fix assuming build time sort works for s390

To speed up the boot process, as mcount_loc needs to be sorted for ftrace to work properly, sorting it at build time is more efficient than boot up and can save milliseconds of time. Unfortunately, this change broke s390 as it will modify the mcount_loc location after the sorting takes place and will put back the unsorted locations. Since the sorting is skipped at boot up if it is believed that it was sorted at run time, ftrace can crash as its algorithms are dependent on the list being sorted. Add a new config BUILDTIME_MCOUNT_SORT that is set when BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine if sorting should take place at boot up.

Event aliasing for events whose name in the form foo-bar-baz is not supported, while foo-bar, foo_bar_baz, and other combinations are, i.e. two hyphens are not supported.

A previous patch preventing "attr->sample_period" values from being overridden in pfm events changed a related behaviour in arm-spe. Before said patch: perf record -c 10000 -e arm_spe_0// -- sleep 1 Would yield an SPE event with period=10000. After the patch, the period in "-c 10000" was being ignored because the arm-spe code initializes sample_period to a non-zero value. This patch restores the previous behaviour for non-libpfm4 events.
