reset: Move reset-simple header out of drivers/reset

2020-06-16T12:19:56+00:00

The reset-simple code can be useful for drivers outside of drivers/reset that have a few reset controls as part of their features. Let's move it to include/linux/reset. Reviewed-by: Philipp Zabel Signed-off-by: Maxime Ripard Signed-off-by: Philipp Zabel

reset: sunxi: declare sun6i_reset_init in a header file

2019-01-28T10:16:04+00:00

Avoid declaring extern functions in c files. To make sure function definition and usage don't get out of sync, declare sun6i_reset_init in a common header. Suggested-by: Stephen Rothwell Signed-off-by: Philipp Zabel

reset: sunxi: use reset-simple driver

2017-10-17T13:35:24+00:00

Use the newly created copies in the reset-simple driver to replace the sunxi platform driver code and reset operations. The separate sunxi driver still remains to register the early reset controllers, but it reuses the reset operations in reset-simple.

reset: sunxi: fix number of reset lines

The Allwinner reset controller has 32-bit registers, but resource_size is measured in bytes, not number of registers. Signed-off-by: Philipp Zabel Acked-by: Chen-Yu Tsai

reset: sunxi: fix for 64-bit compilation

2017-03-15T11:19:12+00:00

The Allwinner reset controller has 32-bit registers, so translating the reset cell number into a register and bit offset should not use any architecture dependent data size. Otherwise this breaks for 64-bit architectures like arm64. Fix this by making it clear that it's the hardware register width which matters here in the calculation.

reset: sunxi: make it explicitly non-modular

2016-10-24T08:45:31+00:00

The Kconfig currently controlling compilation of this code is: drivers/reset/Kconfig:config RESET_SUNXI drivers/reset/Kconfig: bool "Allwinner SoCs Reset Driver" if COMPILE_TEST && !ARCH_SUNXI drivers/reset/Kconfig: default ARCH_SUNXI or arch/arm/mach-sunxi/Kconfig:menuconfig ARCH_SUNXI arch/arm/mach-sunxi/Kconfig: bool "Allwinner SoCs" if ARCH_MULTI_V7 ...meaning that it currently is not being built as a module by anyone. Lets remove the few remaining traces of modular macro usage, so that when reading the driver there is no doubt it is builtin-only. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

reset: check return value of reset_controller_register()
