2021-10-20sh: Use of_get_cpu_hwid()Rob Herring
Replace open coded parsing of CPU nodes' 'reg' property with of_get_cpu_hwid().

2020-12-07sh: boards: Replace <linux/clk-provider.h> by <linux/of_clk.h>Geert Uytterhoeven
The SuperH/J2 DT platform code is not a clock provider, and just needs to call of_clk_init(). Hence it can include <linux/of_clk.h> instead of <linux/clk-provider.h>.

2020-10-25treewide: Convert macro and uses of __section(foo) to __section("foo")Joe Perches
Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms. Conversion done using the script at: https://lore.kernel.org/lkml/75393e5ddc272dc7403de74d645e6c6e0f4e70eb.camel@perches.com/2-convert_section.pl Signed-off-by: Joe Perches <joe@perches.com> Reviewed-by: Nick Desaulniers <ndesaulniers@gooogle.com> Reviewed-by: Miguel Ojeda <ojeda@kernel.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2019-04-05sh: fix multiple function definition build errorsRandy Dunlap
Many of the sh CPU-types have their own plat_irq_setup() and arch_init_clk_ops() functions, so these same (empty) functions in arch/sh/boards/of-generic.c are not needed and cause build errors. If there is some case where these empty functions are needed, they can be retained by marking them as "__weak" while at the same time making builds that do not need them succeed. Fixes these build errors: arch/sh/boards/of-generic.o: In function `plat_irq_setup': (.init.text+0x134): multiple definition of `plat_irq_setup' arch/sh/kernel/cpu/sh2/setup-sh7619.o:(.init.text+0x30): first defined here arch/sh/boards/of-generic.o: In function `arch_init_clk_ops': (.init.text+0x118): multiple definition of `arch_init_clk_ops' arch/sh/kernel/cpu/sh2/clock-sh7619.o:(.init.text+0x0): first defined here Link: http://lkml.kernel.org/r/9ee4e0c5-f100-86a2-bd4d-1d3287ceab31@infradead.org Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Reported-by: kbuild test robot <lkp@intel.com> Cc: Takashi Iwai <tiwai@suse.de> Cc: Yoshinori Sato <ysato@users.sourceforge.jp> Cc: Rich Felker <dalias@libc.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2018-12-18sh: remove board_time_init() callbackArnd Bergmann
The only remaining user of board_time_init() is the of-generic machine, and that just calls the global timer_init() function. Calling that one has no effect on non-DT platforms, so we can simply call it unconditionally in place of board_time_init(). Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2018-09-28SH: use for_each_of_cpu_node iteratorRob Herring
Use the for_each_of_cpu_node iterator to iterate over cpu nodes. This has the side effect of defaulting to iterating using "cpu" node names in preference to the deprecated (for FDT) device_type == "cpu".

2018-04-12sh: fix memory corruption of unflattened device treeRich Felker
unflatten_device_tree() makes use of memblock allocation, and therefore must be called before paging_init() migrates the memblock allocation data to the bootmem framework. Otherwise the record of the allocation for the expanded device tree will be lost, and will eventually be clobbered when allocated for another use. Signed-off-by: Rich Felker <dalias@libc.org>

2016-06-23of: iommu: make of_iommu_init() postcore_initcall_syncKefeng Wang
The of_iommu_init() is called multiple times by arch code, make it postcore_initcall_sync, then we can drop relevant calls fully. Note, the IOMMUs should have a chance to perform some basic initialisation before we start adding masters to them. So postcore_initcall_sync is good choice, it ensures of_iommu_init() called before of_platform_populate.

2016-03-17sh: add SMP method selection to device tree pseudo-boardRich Felker

2016-03-17sh: add device tree support and generic board using device treeRich Felker
Add a new pseudo-board, within the existing SH boards/machine-vectors framework, which does not represent any actual hardware but instead requires all hardware to be described by the device tree blob provided by the boot loader. Changes made are thus non-invasive and do not risk breaking support for legacy boards. New hardware, including the open-hardware J2 and associated SoC devices, will use device free from the outset. Legacy SH boards can transition to device tree once all their hardware has device tree bindings, driver support for device tree, and a dts file for the board. It is intented that, once all boards are supported in the new framework, the existing machine-vectors framework should be removed and the new device tree setup code integrated directly.
