2017-09-04mtd: lantiq-flash: drop check of boot selectHauke Mehrtens1-6/+0
Do not check which flash type the SoC was booted from before using this driver. Assume that the device tree is correct and use this driver when it was added to device tree. This also removes a build dependency to the SoC code.

2015-11-11mtd: drop unnecessary partition parser dataBrian Norris1-3/+2
We should assign the MTD dev.of_node instead of the parser data field. This gets us the equivalent partition parser behavior with fewer special fields and parameter passing. Also convert several of these to mtd_device_register(), since we don't need the 2nd and 3rd parameters anymore.

2014-03-10mtd: delete non-required instances of include <linux/init.h>Paul Gortmaker1-1/+0
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

Convert all uses of devm_request_and_ioremap() to the newly introduced devm_ioremap_resource() which provides more consistent error handling. devm_ioremap_resource() provides its own error messages so all explicit error messages can be removed from the failure code paths.

The first 3 arguments of 'mtd_device_parse_register()' are pointers, but many callers pass '0' instead of 'NULL'. Fix this globally.
