2023-08-23nvmem: Explicitly include correct DT includesRob Herring1-1/+0
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-04-05nvmem: bcm-ocotp: Use devm_platform_ioremap_resource()Yang Li1-3/+1
According to commit 7945f929f1a7 ("drivers: provide devm_platform_ioremap_resource()"), convert platform_get_resource(), devm_ioremap_resource() to a single call to use devm_platform_ioremap_resource(), as this is exactly what this function does.

2017-11-08nvmem: set nvmem->owner to nvmem->dev->driver->owner if unsetMasahiro Yamada1-1/+0
All nvmem drivers are supposed to set the owner field of struct nvmem_config, but this matches nvmem->dev->driver->owner. As far as I see in drivers/nvmem/ directory, all the drivers are the case. So, make nvmem_register() set the nvmem's owner to the associated driver's owner unless nvmem_config sets otherwise. Remove .owner settings in the drivers that are now redundant.
