nvmem: imx-iim: Use of_device_get_match_data()

2021-02-04T16:04:18+00:00

The retrieval of driver data via of_device_get_match_data() can make
the code simpler.

Use of_device_get_match_data() to simplify the code.

nvmem: imx-iim: use devm_platform_ioremap_resource() to simplify code

2019-04-25T17:43:13+00:00

Use the new helper devm_platform_ioremap_resource() which wraps the
platform_get_resource() and devm_ioremap_resource() together, to
simplify the code.

nvmem: imx-iim: Do not use "&pdev->dev" explicitly

2018-03-14T18:28:14+00:00

There's already "dev" variable for that. Use it.

nvmem: imx-iim: Convert to use devm_nvmem_register()

2018-03-14T18:28:14+00:00

Drop all of the code related to .remove hook and make use of
devm_nvmem_register() instead.

nvmem: set nvmem->owner to nvmem->dev->driver->owner if unset

2017-11-08T12:54:17+00:00

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.

nvmem: imx-iim: use stack for nvmem_config instead of malloc'ing it

2017-11-08T12:54:16+00:00

nvmem_register() copies all the members of nvmem_config to
nvmem_device.  So, nvmem_config is one-time use data during
probing.  There is no point to keep it until the driver detach.
Using stack should be no problem because nvmem_config is pretty
small.

nvmem: Add driver for the i.MX IIM

2017-04-08T15:51:48+00:00

This adds a readonly nvmem driver for the i.MX IC Identification Module
(IIM). The IIM is found on the older i.MX SoCs like the i.MX25, i.MX27,
i.MX31, i.MX35, i.MX51 and the i.MX53.

The IIM can control up to 8 fuse banks with 256 bit each. Not all of the
banks are equipped on the different SoCs. The actual number of fuses
differ from 512 on the i.MX27 and 1152 on the i.MX53.

The fuses are one time writable, but writing is currently not supported
in the driver.
