* | | i2c: move i2c_omap's probe function to .devinit.textUwe Kleine-König2010-03-07
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A pointer to omap_i2c_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

| | |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current i2c-omap driver is set up for 32-bit registers, which corresponds to most OMAP devices. However, OMAP730/850 based devices use a 16-bit register size. This change modifies the driver to perform a runtime CPU type check to determine the register sizes, and uses a bit shift of either 1 or 2 bits to compute the proper register sizes for all registers.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The start/stop condtions are set in different places repetedly in the i2c-pnx driver. Beside in i2c_pnx_start and i2c_pnx_stop the start/stop bit are also set during the transfer of a i2c message in the master_xmit/rcv calls. This is wrong since we can't set the start/stop condition during the transaction of a single message any way. As a matter of fact, the driver will sometimes set both the start and the stop bits at one time. This can be easily reproduced by sending a simple read request like e.g struct i2c_msg msgs[] = { { addr, 0, 1, buf }, { addr, I2C_M_RD, offset, buf } }; While processing the first message the i2c_pnx_master_xmit will set both the start_bit and the stop_bit, which will eventually confuse the slave. Fixed by remove setting start/stop condition from the transmit routines. Signed-off-by: Luotao Fu <l.fu@pengutronix.de> Signed-off-by: Ben Dooks <ben-linux@fluff.org>

* | i2c: Add SMBus alert supportJean Delvare2010-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SMBus alert support. The SMBus alert protocol allows several SMBus slave devices to share a single interrupt pin on the SMBus master, while still allowing the master to know which slave triggered the interrupt. This is based on preliminary work by David Brownell. The key difference between David's implementation and mine is that his was part of i2c-core, while mine is split into a separate, standalone module named i2c-smbus. The i2c-smbus module is meant to include support for all SMBus extensions to the I2C protocol in the future. The benefit of this approach is a zero cost for I2C bus segments which do not need SMBus alert support. Where David's implementation increased the size of struct i2c_adapter by 7% (40 bytes on i386), mine doesn't touch it. Where David's implementation added over 150 lines of code to i2c-core (+10%), mine doesn't touch it. The only change that touches all the users of the i2c subsystem is a new callback in struct i2c_driver (common to both implementations.) I seem to remember Trent was worried about the footprint of David'd implementation, hopefully mine addresses the issue.

* | | i2c-tiny-usb: Fix on big-endian systemsJean Delvare2010-02-05
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The functionality bit vector is always returned as a little-endian 32-bit number by the device, so it must be byte-swapped to the host endianness. On the other hand, the delay value is handled by the USB stack, so no byte swapping is needed on our side.
