2010-10-01ARM: imx/pca100: only specify i2c device type onceUwe Kleine-König
The first argument to I2C_BOARD_INFO is used to assign .type, so it should not be specified a second time. For the rtc-pcf8563/pcf8563 entry gcc preferred pcf8563, so did I. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

2010-10-01ARM: imx: use platform ids for spi_imx devicesUwe Kleine-König

2010-10-01spi/imx: add support for imx51's eCSPI and CSPIUwe Kleine-König
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.

2010-10-01spi/imx: get rid of more ifs depending on the used cpuUwe Kleine-König
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).

2010-10-01spi/imx: convert driver to use platform idsUwe Kleine-König
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.)

2010-10-01hfsplus: fix rename over directoriesChristoph Hellwig
When renaming over a directory we need to use hfsplus_rmdir instead of hfsplus_unlink to evict the victim. This makes sure we properly error out on non-empty directory as required by Posix (BZ #16571), and it also makes sure we do the right thing in case i_nlink will every be set correctly for directories on hfsplus.

2010-10-01hfsplus: add missing extent locking in hfsplus_write_inodeChristoph Hellwig
Most of the extent handling code already does proper SMP locking, but hfsplus_write_inode was calling into hfsplus_ext_write_extent without taking the extents_lock. Fix this by splitting hfsplus_ext_write_extent into an internal helper that expects the lock, and a public interface that first acquires it. Also add a few locking asserts and document the locking rules in hfsplus_fs.h. Signed-off-by: Christoph Hellwig <hch@tuxera.com>
