* mfd: syscon: Don't call request_iomem_region()Andrey Smirnov2016-07-191-6/+0
| | | | | | | | | | | | | | On platforms that mix dedicated IP block register space with miscellaneous registers it is necessary to share register window between syscon and dedicated IP block driver. Calling request_iomem_region() implies exclusive ownership of the region, which, in the case above could not happen. This change also makes this driver's behaviour to that of its Linux kernel counterpart. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | This reverts commit 8a6896971d093b9d8d1c36eb0d7af891b6ca5369. With this patch it's no longer possible to call detect on the physical device which is necessary for example to make environment on MMC work. Unlike the commit message for 8a6896971d claims mci_detect_card() is not called from mci_register(). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When moving a PEB the leb_write_trylock() function is called. As the function never returns 0 UBI will end up in an endless loop. Noticed the issue when fastmap has been enabled and data is beeing copied several times to a UBI volume. When UBI tries to move the anchor PEB, the issue comes up. The leb_write_trylock() is now equal to the leb_write_lock(). But kept it for easier maintaince in future when syncing with kernel.

Unfortunately the architecture and abstractions disappeared during this period. This patch refactors the framework to recreate the abstractions. The main focus was the backend with its storage. The main use-case was to offer better NAND support with less erase cycles and interchangeable data formats (dtb,raw). The general architecture now has a backend which consists of a data format and storage. The storage consists of multiple storage buckets each holding exactly one copy of the state data. A data format describes a data serialization for the state framework. This can be either dtb or raw. A storage bucket is a storage location which is used to store any data. There is a (new) circular type which writes changes behind the last written data and therefore reduces the number of erases. The other type is a direct bucket which writes directly to a storage offset for all non-erase storage. Furthermore this patch splits up all classes into different files in a subdirectory. This is currently all in one patch as I can't see a good way to split the changes up without having a non-working state framework in between. The following diagram shows the new architecture roughly: .----------. | state | '----------' | | v .----------------------------. | state_backend | |----------------------------| | + state_load(*state); | | + state_save(*state); | | + state_backend_init(...); | | | | | '----------------------------' | | The format describes | | how the state data | '-------------> is serialized | .--------------------------------------------. | | state_backend_format <INTERFACE> | | |--------------------------------------------| | | + verify(*format, magic, *buf, len); | | | + pack(*format, *state, **buf, len); | | | + unpack(*format, *state, *buf, len); | | | + get_packed_len(*format, *state); | | | + free(*format); | | '--------------------------------------------' | ^ ^ | * * | * * | .--------------------. .--------------------. | | backend_format_dtb | | backend_format_raw | | '--------------------' '--------------------' | | | v .----------------------------------------------------------. | state_backend_storage | |----------------------------------------------------------| | + init(...); | | + free(*storage); | | + read(*storage, *format, magic, **buf, *len, len_hint); | | + write(*storage, *buf, len); | | + restore_consistency(*storage, *buf, len); | '----------------------------------------------------------' | The backend storage is responsible to manage multiple data copies and distribute them onto several buckets.
