2025-02-18ARM: imx: Switch to use hrtimer_setup()Nam Cao
hrtimer_setup() takes the callback function pointer as argument and initializes the timer completely. Replace hrtimer_init() and the open coded initialization of hrtimer::function with the new setup mechanism.

According to atmel,maxtouch.yaml, the correct property that describes the GPIO connected to the touchscreen reset line is 'reset-gpios'.

The btt3 device' HW revisions from 0 to 2 use imx287 SoC and are to some extend similar to already upstreamed XEA devices, hence are using common imx28-lwe.dtsi file. New, imx28-btt3.dtsi has been added to embrace common DTS properties for different HW revisions for this device. As a result - changes introduced in imx28-btt3-[012].dts are minimal.

2025-02-03ARM: shmobile: rcar-gen2: Remove CMA reservation codeGeert Uytterhoeven
If CONFIG_HIGHMEM=y, two reserved blocks are allocated on R-Car Gen2: cma: Reserved 256 MiB at 0x70000000 on node -1 cma: Reserved 64 MiB at 0x6c000000 on node -1 The first block is reserved by the family-specific rcar_gen2_reserve(), the second by the common arm_memblock_init() (shmobile_defconfig sets CONFIG_CMA_SIZE_MBYTES=64). As both blocks are reserved (eventually) using dma_contiguous_reserve_area(), they both have the same name ("reserved"). Hence if CONFIG_CMA_SYSFS=y: sysfs: cannot create duplicate filename '/kernel/mm/cma/reserved' ... cma_sysfs_init from do_one_initcall+0x84/0x178 ... kobject: kobject_add_internal failed for reserved with -EEXIST, don't try to register things with the same name in the same directory. This causes cma_sysfs_init() to fail completely, and not to create /sys/kernel/mm/cma/ at all. Fix this by dropping the R-Car Gen2-specific reservation. Compared to when it was introduced, now there exist more flexible mechanisms to control the size of memory reserved for CMA. Users can reserve more memory by increasing CONFIG_CMA_SIZE_MBYTES, passing the cma=<N> kernel command line parameter, or adding a reserved-memory/linux,cma node to DT.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core and debugfs updates from Greg KH: "Here is the big set of driver core and debugfs updates for 6.14-rc1. Included in here is a bunch of driver core, PCI, OF, and platform rust bindings (all acked by the different subsystem maintainers), hence the merge conflict with the rust tree, and some driver core api updates to mark things as const, which will also require some fixups due to new stuff coming in through other trees in this merge window. There are also a bunch of debugfs updates from Al, and there is at least one user that does have a regression with these, but Al is working on tracking down the fix for it. In my use (and everyone else's linux-next use), it does not seem like a big issue at the moment. Here's a short list of the things in here: - driver core rust bindings for PCI, platform, OF, and some i/o functions. We are almost at the "write a real driver in rust" stage now, depending on what you want to do. - misc device rust bindings and a sample driver to show how to use them - debugfs cleanups in the fs as well as the users of the fs api for places where drivers got it wrong or were unnecessarily doing things in complex ways. - driver core const work, making more of the api take const * for different parameters to make the rust bindings easier overall. - other small fixes and updates All of these have been in linux-next with all of the aforementioned merge conflicts, and the one debugfs issue, which looks to be resolved "soon"" * tag 'driver-core-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (95 commits) rust: device: Use as_char_ptr() to avoid explicit cast rust: device: Replace CString with CStr in property_present() devcoredump: Constify 'struct bin_attribute' devcoredump: Define 'struct bin_attribute' through macro rust: device: Add property_present() saner replacement for debugfs_rename() orangefs-debugfs: don't mess with ->d_name octeontx2: don't mess with ->d_parent or ->d_parent->d_name arm_scmi: don't mess with ->d_parent->d_name slub: don't mess with ->d_name sof-client-ipc-flood-test: don't mess with ->d_name qat: don't mess with ->d_name xhci: don't mess with ->d_iname mtu3: don't mess wiht ->d_iname greybus/camera - stop messing with ->d_iname mediatek: stop messing with ->d_iname netdevsim: don't embed file_operations into your structs b43legacy: make use of debugfs_get_aux() b43: stop embedding struct file_operations into their objects carl9170: stop embedding file_operations into their objects ...
2025-01-28treewide: const qualify ctl_tables where applicableJoel Granados
Add the const qualifier to all the ctl_tables in the tree except for watchdog_hardlockup_sysctl, memory_allocation_profiling_sysctls, loadpin_sysctl_table and the ones calling register_net_sysctl (./net, drivers/inifiniband dirs). These are special cases as they use a registration function with a non-const qualified ctl_table argument or modify the arrays before passing them on to the registration function. Constifying ctl_table structs will prevent the modification of proc_handler function pointers as the arrays would reside in .rodata. This is made possible after commit 78eb4ea25cd5 ("sysctl: treewide: constify the ctl_table argument of proc_handlers") constified all the proc_handlers. Created this by running an spatch followed by a sed command: Spatch: virtual patch @ depends on !(file in "net") disable optional_qualifier @ identifier table_name != { watchdog_hardlockup_sysctl, iwcm_ctl_table, ucma_ctl_table, memory_allocation_profiling_sysctls, loadpin_sysctl_table }; @@ + const struct ctl_table table_name [] = { ... }; sed: sed --in-place \ -e "s/struct ctl_table .table = &uts_kern/const struct ctl_table *table = \&uts_kern/" \ kernel/utsname_sysctl.c Reviewed-by: Song Liu <song@kernel.org> Acked-by: Steven Rostedt (Google) <rostedt@goodmis.org> # for kernel/trace/ Reviewed-by: Martin K.
