2009-02-24i2c: Make sure i2c_algo_bit_data.timeout is HZ-independentJean Delvare
i2c_algo_bit_data.timeout is supposed to be in jiffies, so drivers should use set this value in terms of HZ. Ultimately I think this field should be discarded in favor of i2c_adapter.timeout, but that's left for a future patch.

2009-02-24i2c-dev: Clarify the unit of ioctl I2C_TIMEOUTJean Delvare
The unit in which user-space can set the bus timeout value is jiffies for historical reasons (back when HZ was always 100.) This is however not good because user-space doesn't know how long a jiffy lasts. The timeout value should instead be set in a fixed time unit. Given the original value of HZ, this unit should be 10 ms, for compatibility. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Wolfram Sang <w.sang@pengutronix.de>
2009-02-24i2c: Timeouts reach -1Roel Kluin
With a postfix decrement these timeouts reach -1 rather than 0, but after the loop it is tested whether they have become 0. As pointed out by Jean Delvare, the condition we are waiting for should also be tested before the timeout. With the current order, you could exit with a timeout error while the job is actually done.

2009-01-07USB: move isp1301_omap to drivers/usb/otgDavid Brownell
This moves the isp1301-omap driver from the drivers/i2c/chips directory (which will be shrinking) into a new drivers/usb/otg directory (which will grow, with more drivers and utilities). Note that OTG infrastructure needs to be initialized before either host or peripheral side USB support, and may be needed before for pure host or pure peripheral configurations.

2009-01-07Input: apanel - convert to new i2c bindingJean Delvare
Convert the apanel driver to the new i2c device driver binding model, as the legacy model is going away soon. In the new model, the apanel driver is no longer scanning all the i2c adapters, instead the relevant bus driver (i2c-i801) is instantiating the device as needed. One side benefit is that the apanel driver will now load automatically on all systems where it is needed.

2009-01-07i2c: Drop I2C_CLASS_ALLJean Delvare
I2C_CLASS_ALL is almost never what bus driver authors really want. These i2c classes are really only about which devices must be probed, not what devices can be present. As device drivers get converted to the new i2c device driver model, only a few device types will keep relying on probing.

2009-01-07i2c: Replace bus_id with dev_name(), dev_set_name()Kay Sievers
This patch is part of a larger patch series which will remove the "char bus_id[20]" name string from struct device. The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id. We want to submit a patch to -next, which will remove bus_id from "struct device", to find the remaining pieces to convert, and finally switch over to the new api, which will remove the 20 bytes array and does no longer have a size limitation.

The I2C controller clears its OCP_SYSCONFIG register after an OCP soft reset. Reprogram OCP_SYSCONFIG for maximum power savings on rev3.6 controllers and beyond. On 2430, this involves setting the module AUTOIDLE bit. On 3430, this includes module AUTOIDLE, wakeup enable, slave smart-idle, and considers only the module functional clock state for idle-ack.

i2c-omap discriminates only between "revision 1" or "greater than revision 1." A following patch introduces code that must also discriminate between rev2.x, rev3.6, and rev3.12 controllers. Support this by storing the full revision data from the I2C_REV register, rather than just a single bit. The revision definitions may need to be extended for other ES levels that aren't currently available here. rev3.6 is what's present on the 2430SDP here (unknown ES revision); rev3.12 is used on the 3430ES2 here.

2008-11-21i2c-omap: fix I2C timeouts due to recursive omap_i2c_{un,}idle()Paul Walmsley
omap_i2c_unidle() and omap_i2c_idle() are called recursively during omap_i2c_probe(). This is evidently unexpected and will wipe out the I2C interrupt enable register the second time that omap_i2c_idle() is called consecutively. Any I2C transactions following a probe of a bus with at least one device on it will then time out. Fix by moving omap_i2c_idle() further up in omap_i2c_probe(). Ensure the I2C controller is marked as idle before the probe starts. Also attempt to catch future reappearances of this bug early in development by warning in omap_i2c_{un,}idle() when they are called recursively. Problem reported by David Brownell <david-b@pacbell.net>. Tested on 3430SDP and 2430SDP.
