2007-10-13i2c-stub: Support multiple chipsJean Delvare
Add support for multiple chips to i2c-stub. I've changed the memory allocation scheme from static to dynamic, so that we don't waste too much memory. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Mark M. Hoffman <mhoffman@lightlink.com>
2007-10-13i2c-bfin-twi: Remove useless twi_lock mutexFrancis Moreau
Remove this unneeded mutex. Indeed it was used to serialize access to the hardware, but this is already done by the i2c-core layer, see 'bus_lock' mutex used by i2c_transfer(). Signed-off-by: Francis Moreau <francis.moro@gmail.com> Acked-by: Bryan Wu <bryan.wu@analog.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-10-13i2c-i801: Add support for the Intel Tolapai SMBusJason Gaston
Add the Intel Tolapai SMBus Controller DID. Signed-off-by: Jason Gaston <jason.d.gaston@intel.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-10-13i2c: Document struct i2c_msgDavid Brownell
Clarify use of the I2C_M_* flags by highlighting the fact that most of them depend on I2C_FUNC_PROTOCOL_MANGLING. Also provide kerneldoc for i2c_smbus_read_block_data() and also for "struct i2c_msg".

2007-10-13i2c/pcf8574: No arbitrary initializationJean Delvare
Do not initialize the PCF8574 with an arbitrary value. Users will have to write the initial value to sysfs themselves. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Aurelien Jarno <aurelien@aurel32.net>

2007-10-13i2c-ibm_iic: Add support for new-style clientsStefan Roese
Use i2c_bit_add_numbered_adapter() if device id specified, so that the i2c-ibm_iic adapter works well with new-style pre-declared devices. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-10-13i2c/tps65010: New-style driver updates, part 2David Brownell
Switch the tps65010 driver into a "new-style" I2C driver, and convert all of its in-tree users (board support for OSK, H2, H3) accordingly. That accounts for most of the board-specific code in this driver; the rest of that code is now moved into board-specific initcalls. Also remove some of the many now-superfluous #includes. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-10-13i2c/tps65010: New-style driver updates, part 1David Brownell
Prepare to convert tps65010 driver to "new style" driver by changing how it references the i2c_client. This lets the eventual patch with driver and platform updates be smaller. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-10-13i2c-core: Make some code staticAdrian Bunk
After the i2c-isa removal some code can become static. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-10-13i2c: New-style devices can support driver model wakeup flagsDavid Brownell
We need to be able to flag I2C devices, such as RTCs, which can issue wake events (usually through IRQ lines). This adds an i2c_board_info.flags bit, and uses it to initialize the i2c device node. (And shrinks a few lines that were overly long.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-10-13i2c: Kill struct i2c_device_idJean Delvare
I2C devices do not have any form of ID as PCI or USB devices have. No driver uses "MODULE_DEVICE_TABLE(i2c, ...)" because it doesn't make sense. So we can get rid of struct i2c_device_id and the associated support code. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Greg KH <greg@kroah.com>

2007-10-13Delete filenames in comments.Dave Jones
Since the x86 merge, lots of files that referenced their own filenames are no longer correct. Rather than keep them up to date, just delete them, as they add no real value. Additionally: - fix up comment formatting in scx200_32.c - Remove a credit from myself in setup_64.c from a time when we had no SCM - remove longwinded history from tsc_32.c which can be figured out from git.

In commit 4665079cbb2a3e17de82f2ab2940b9f97f37d65e ("[NETNS]: Move some code into __init section when CONFIG_NET_NS=n") we got a new section - .exit.text.refok (more of 'let's tell modpost that some bogus calls are not bogus', a-la text.init.refok).

2007-10-13minimal build fixes for uml (fallout from x86 merge)Al Viro
a) include/asm-um/arch can't just point to include/asm-$(SUBARCH) now b) arch/{i386,x86_64}/crypto are merged now c) subarch-obj needed changes d) cpufeature_64.h should pull "cpufeature_32.h", not <asm/cpufeature_32.h> since it can be included from asm-um/cpufeature.h e) in case of uml-i386 we need CONFIG_X86_32 for make and gcc, but not for Kconfig f) sysctl.c shouldn't do vdso_enabled for uml-i386 (actually, that one should be registered from corresponding arch/*/kernel/*, with ifdef going away; that's a separate patch, though). With that and with Stephen's patch ("[PATCH net-2.6] uml: hard_header fix") we have uml allmodconfig building both on i386 and amd64.

* Convert {ide_hwif_t,ide_pci_device_t}->host_flag to be u16. * Add IDE_HFLAG_POST_SET_MODE host flag to indicate the need to program the host for the transfer mode after programming the device. Set it in au1xxx-ide, amd74xx, cs5530, cs5535, pdc202xx_new, sc1200, pmac and via82cxxx host drivers. * Add IDE_HFLAG_NO_SET_MODE host flag to indicate the need to completely skip programming of host/device for the transfer mode ("smart" hosts). Set it in it821x host driver and check it in ide_tune_dma(). * Add ide_set_pio_mode()/ide_set_dma_mode() helpers and convert all direct ->set_pio_mode/->speedproc users to use these helpers. * Move ide_config_drive_speed() calls from ->set_pio_mode/->speedproc methods to callers. * Rename ->speedproc method to ->set_dma_mode, make it void and update all implementations accordingly. * Update ide_set_xfer_rate() comments. * Unexport ide_config_drive_speed(). v2: * Fix issues noticed by Sergei: - export ide_set_dma_mode() instead of moving ->set_pio_mode abuse wrt to setting DMA modes from sc1200_set_pio_mode() to do_special() - check IDE_HFLAG_NO_SET_MODE in ide_tune_dma() - check for (hwif->set_pio_mode) == NULL in ide_set_pio_mode() - check for (hwif->set_dma_mode) == NULL in ide_set_dma_mode() - return -1 from ide_set_{pio,dma}_mode() if ->set_{pio,dma}_mode == NULL - don't set ->set_{pio,dma}_mode on it821x in "smart" mode - fix build problem in pmac.c - minor fixes in au1xxx-ide.c/cs5530.c/siimage.c - improve patch description Changes in behavior caused by this patch: - HDIO_SET_PIO_MODE ioctl would now return -ENOSYS for attempts to change PIO mode if it821x controller is in "smart" mode - removal of two debugging printk-s (from cs5530.c and sc1200.c) - transfer modes 0x00-0x07 passed from user space may be programmed twice on the device (not really an issue since 0x00 is not supported correctly by any host driver ATM, 0x01 is not supported at all and 0x02-0x07 are invalid) Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* Check ide_config_drive_speed() return value. * While at also call ide_config_drive_speed() if the transfer mode is XFER_PIO_SLOW (this case happens iff the transfer mode has already been set on the device by ide-proc.c::set_xfer_rate()) and remove redundant setting of ->{init,current}_speed. * Bump driver version.
