This prepares adding support for imx51's eCSPI. This IP has seperate control and config bits for all four supported chip selects, so the config routine needs to know which chip select is being used even if the chipselect is realized by a gpio. Acked-by:

Nearly everything that is needed is provided by the version of the SPI IP. Now the only checks left using cpu_is_... are clk divider tuning on mx21/mx27 and autodetection (which will die soon). Acked-by:

This has the advantage not to need to much cpu_is_... macros. Still more when imx51 support is added which has two different spi interfaces which would introduce additional checks on the device id. With this setup it's not possible for the compiler anymore to detect the unused functions, so four additional kconfig symbols are introduced to ifdef out the unneeded functions in the callback array and all these functions are marked with __maybe_unused to suppress the corresponding gcc warnings. Comparing the driver footprint with and without the patch for a mx27 kernel yields: add/remove: 2/0 grow/shrink: 2/0 up/down: 280/0 (280) function old new delta spi_imx_devtype - 192 +192 spi_imx_probe 980 1032 +52 spi_imx_devtype_data - 32 +32 spi_imx_setupxfer 276 280 +4 Later when the platform code is updated to use the platform ids, the autodetection can be removed which will make the driver a bit smaller again. (~60 Bytes in my test.) Acked-by:

Group soc specific data in a global struct instead of repeating it for each call to imxXX_add_spi_imxX. The structs holding the actual data are placed in .init.constdata and so don't do much harm. Compared to the previous approach this reduces code size to call imx_add_spi_imx. Acked-by:

When you don't use !E or !I but only !F, then it's very easy to miss including some functions, structs etc. in documentation. To help finding which ones were missed, allow printing out the unused ones as warnings. For example, using this on mac80211 yields a lot of warnings like this: Warning: didn't use docs for DOC: mac80211 workqueue Warning: didn't use docs for ieee80211_max_queues Warning: didn't use docs for ieee80211_bss_change Warning: didn't use docs for ieee80211_bss_conf when generating the documentation for it.

There is a problem in hibernate_preallocate_memory() that it calls preallocate_image_memory() with an argument that may be greater than the total number of available non-highmem memory pages. If that's the case, the OOM condition is guaranteed to trigger, which in turn can cause significant slowdown to occur during hibernation. To avoid that, make preallocate_image_memory() adjust its argument before calling preallocate_image_pages(), so that the total number of saveable non-highem pages left is not less than the minimum size of a hibernation image. Change hibernate_preallocate_memory() to try to allocate from highmem if the number of pages allocated by preallocate_image_memory() is too low. Modify free_unnecessary_pages() to take all possible memory allocation patterns into account. Reported-by:
