treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59+00:00

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

sh: pci: Modernize printing of kernel messages

2020-08-15T02:05:10+00:00

- Convert from printk() to pr_*(), - Add missing continuations, - Join broken messages. Note that printk(KERN_DEBUG ...) is retained, to preserve behavior (pr_debug() is a dummy if DEBUG is not defined). Signed-off-by: Geert Uytterhoeven Tested-by: Guenter Roeck Signed-off-by: Rich Felker

sh: Remove SH5-based Cayman platform

2020-08-15T02:05:06+00:00

Since the removal of core support for SH5, Cayman support can no longer be selected. Fixes: 37744feebc086908 ("sh: remove sh5 support") Signed-off-by: Geert Uytterhoeven Signed-off-by: Rich Felker

sh: remove sh5 support

2020-06-01T18:48:52+00:00

sh5 never became a product and has probably never really worked. Remove it by recursively deleting all associated Kconfig options and all corresponding files. Reviewed-by: Geert Uytterhoeven Signed-off-by: Arnd Bergmann Signed-off-by: Rich Felker

sh: Replace setup_irq() by request_irq()

2020-03-29T19:03:43+00:00

request_irq() is preferred over setup_irq(). Invocations of setup_irq() occur after memory allocators are ready. setup_irq() was required in older kernels as the memory allocator was not available during early boot. Hence replace setup_irq() by request_irq().

remove ioremap_nocache and devm_ioremap_nocache

2020-01-06T08:45:59+00:00

ioremap has provided non-cached semantics by default since the Linux 2.6 days, so remove the additional ioremap_nocache interface. Signed-off-by: Christoph Hellwig Acked-by: Arnd Bergmann

drivers: Fix boot problem on SuperH

2019-12-10T14:51:20+00:00

SuperH images crash too eearly to display any console output. Bisect points to commit 507fd01d5333 ("drivers: move the early platform device support to arch/sh"). An analysis of that patch suggests that early_platform_cleanup() is now called at the wrong time. Restoring its call point fixes the problem.

Merge tag 'driver-core-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2019-11-27T19:06:20+00:00

Pull driver core updates from Greg KH: "Here is the "big" set of driver core patches for 5.5-rc1 There's a few minor cleanups and fixes in here, but the majority of the patches in here fall into two buckets: - debugfs api cleanups and fixes - driver core device link support for boot dependancy issues The debugfs api cleanups are working to slowly refactor the debugfs apis so that it is even harder to use incorrectly. That work has been happening for the past few kernel releases and will continue over time, it's a long-term project/goal The driver core device link support missed 5.4 by just a bit, so it's been sitting and baking for many months now. It's from Saravana Kannan to help resolve the problems that DT-based systems have at boot time with dependancy graphs and kernel modules. Turns out that no one has actually tried to build a generic arm64 kernel with loads of modules and have it "just work" for a variety of platforms (like a distro kernel). The big problem turned out to be a lack of dependency information between different areas of DT entries, and the work here resolves that problem and now allows devices to boot properly, and quicker than a monolith kernel. All of these patches have been in linux-next for a long time with no reported issues" * tag 'driver-core-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (68 commits) tracing: Remove unnecessary DEBUG_FS dependency of: property: Add device link support for interrupt-parent, dmas and -gpio(s) debugfs: Fix !DEBUG_FS debugfs_create_automount of: property: Add device link support for "iommu-map" of: property: Fix the semantics of of_is_ancestor_of() i2c: of: Populate fwnode in of_i2c_get_board_info() drivers: base: Fix Kconfig indentation firmware_loader: Fix labels with comma for builtin firmware driver core: Allow device link operations inside sync_state() driver core: platform: Declare ret variable only once cpu-topology: declare parse_acpi_topology in crypto: hisilicon: no need to check return value of debugfs_create functions driver core: platform: use the correct callback type for bus_find_device firmware_class: make firmware caching configurable driver core: Clarify documentation for fwnode_operations.add_links() mailbox: tegra: Fix superfluous IRQ error message net: caif: Fix debugfs on 64-bit platforms mac80211: Use debugfs_create_xul() helper media: c8sectpfe: no need to check return value of debugfs_create functions of: property: Add device link support for iommus, mboxes and io-channels ...

sh: Use pr_warn instead of pr_warning

2019-10-18T11:52:05+00:00

As said in commit f2c2cbcc35d4 ("powerpc: Use pr_warn instead of pr_warning"), removing pr_warning so all logging messages use a consistent _warn style. Let's do it.

sh: add the sh_ prefix to early platform symbols

2019-10-07T11:50:48+00:00

Old early platform device support is now sh-specific. Before moving on to implementing new early platform framework based on real platform devices, prefix all early platform symbols with 'sh_'.
