drivers: slimbus: Directly use ida_alloc()/free()

2022-07-08T13:43:42+00:00

Use ida_alloc()/ida_free() instead of deprecated ida_simple_get()/ida_simple_remove() . Signed-off-by: keliu Signed-off-by: Srinivas Kandagatla Link: https://lore.kernel.org/r/20220706101131.6934-2-srinivas.kandagatla@linaro.org Signed-off-by: Greg Kroah-Hartman

bus: Make remove callback return void

2021-07-21T09:53:42+00:00

The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

slimbus: core: do not enter to clock pause mode in core

2020-09-25T12:41:50+00:00

Let the controller logic decide when to enter into clock pause mode! Entering in to pause mode during unregistration does not really make sense as the controller is totally going down at that point in time.

slimbus: core: check get_addr before removing laddr ida

2020-09-25T12:41:50+00:00

logical address can be either assigned by the SLIMBus controller or the core. Core uses IDA in cases where get_addr callback is not provided by the controller. Core already has this check while allocating IDR, however during absence reporting this is not checked. This patch fixes this issue.

slimbus: core: Set fwnode for a device when setting of_node

2020-05-15T14:21:07+00:00

When setting the of_node for a newly created device, also set the fwnode. This allows fw_devlink feature to work for slimbus devices. Also, remove some unnecessary NULL checks. The functions in question already do NULL checks.

slimbus: core: generate uevent for non-dt only

2019-06-20T08:45:22+00:00

Rely on MODULE_ALIAS() for automatic kernel module loading, rather than basing it on the OF compatible. This ensures that drivers without of_device_id table, such as wcd9335, will be automatically loaded.
