reset: berlin: fix OF node leak in probe() error path

2024-09-02T09:51:19+00:00

Driver is leaking OF node reference on memory allocation failure. Acquire the OF node reference after memory allocation to fix this and keep it simple.

reset: berlin: support module build

2021-06-07T10:45:59+00:00

Make reset-berlin driver to be tristate module, support to build as a module, this is useful for GKI.

reset: berlin: make it explicitly non-modular

2016-10-24T08:43:40+00:00

The Kconfig currently controlling compilation of this code is: drivers/reset/Kconfig:config RESET_BERLIN drivers/reset/Kconfig: bool "Berlin Reset Driver" if COMPILE_TEST drivers/reset/Kconfig: default ARCH_BERLIN or arch/arm/mach-berlin/Kconfig:menuconfig ARCH_BERLIN arch/arm/mach-berlin/Kconfig: bool "Marvell Berlin SoCs" if ARCH_MULTI_V7 or arch/arm64/Kconfig.platforms:config ARCH_BERLIN arch/arm64/Kconfig.platforms: bool "Marvell Berlin SoC Family" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, 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 was (or is now) contained at the top of the file in the comments.

reset: berlin: drop DT cell size check

reset: check return value of reset_controller_register()

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

With proper platform driver probing for berlin reset driver, drop the arch_initcall workaround. Signed-off-by: Antoine Tenart Acked-by: Philipp Zabel Signed-off-by: Sebastian Hesselbarth

reset: berlin: convert to a platform driver

2015-05-18T15:52:36+00:00

The Berlin reset controller was introduced without being a platform driver because of a needed DT rework: the node describing the reset controller also describes the pinctrl and clk controllers... Prepare conversion by adding a platform driver probe to a new compatible "marvell,berlin2-reset" with syscon regmap.
