Currently the uarts and timer only work because they are turned on by reset default. Make them secondary clocks of their corresponding peripheral clocks to make sure they are turned on when necessary. Also, register some clocks to get rid of compiler warnings Signed-off-by:

The driver recently learned to handle platform ids. Make use of this new feature. The up side is that the driver needs less knowledge about the spi interfaces used on different SoCs. Acked-by:

i.MX51 comes with two eCSPI interfaces (that are quite different from what was known before---the tried and tested Freescale way) and a CSPI interface that is identical to the devices found on i.MX25 and i.MX35. This patch is a merge of two very similar patches (by Jason Wang and Sascha Hauer resp.) plus a (now hopefully correct) reimplementation of the clock calculation. Acked-by:

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:

Further remove FIXED_PHY as it breaks the ethernet. VGA_CONSOLE isn't selectable anymore since fb78b51c. EXT3_DEFAULTS_TO_ORDERED defaults to y since aa32a796. INOTIFY is gone since 2dfc1cae. CONFIG_DETECT_SOFTLOCKUP is gone since e16bb1d7. Enable TMPFS for udev. KEYS is selected by NFS_USE_KERNEL_DNS Signed-off-by:
