reset: sunxi: use reset-simple driver

2017-10-17T13:35:24Z

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

2017-08-11T15:48:56Z

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

2017-03-15T11:19:12Z

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

2016-10-24T08:45:31Z

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: sunxi: use devm_reset_controller_register()

Use devm_reset_controller_register() for the reset controller registration and drop the .remove callback. Signed-off-by: Masahiro Yamada Signed-off-by: Philipp Zabel

reset: sunxi: Make reset_control_ops const

The sunxi_reset_ops structure is never modified. Make it const. Signed-off-by: Philipp Zabel Acked-by: Maxime Ripard

reset: check return value of reset_controller_register()

2015-11-16T08:23:47Z

Currently, reset_controller_register() always return 0, but it would be better to check its return code. Signed-off-by: Masahiro Yamada Acked-by: Sören Brinkmann Signed-off-by: Philipp Zabel

reset: sunxi: mark the of_device_id array as __initconst

2015-11-16T08:23:47Z

Since this array is static const, it should be marked as __initconst. Signed-off-by: Philipp Zabel Acked-by: Maxime Ripard

reset: sunxi: fix spinlock initialization

2015-01-17T03:11:31Z

Call spin_lock_init() before the spinlocks are used, both in early init and probe functions preventing a lockdep splat. I have been observing lockdep complaining [1] during boot on my a80 optimus [2] when CONFIG_PROVE_LOCKING has been enabled. This patch resolves the splat, and has been tested on a few other sunxi platforms without issue.

reset: drop owner assignment from platform_drivers

2014-10-20T14:21:30Z

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang
