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.

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.

Make the driver report an ENXIO error immediately upon NAK instead of waiting for another interrupt and getting a timeout. When reading from a device that is not present or declines to respond to, e.g., a non-existent register address, CPM immediately reports a NAK condition in the TxBD, but the driver kept waiting until a timeout, which takes 1 second and causes an ugly console error message.

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. Boot-tested on 2430SDP and 3430SDP. Signed-off-by: NPaul Walmsley <paul@pwsan.com> Cc: Richard Woodruff <r-woodruff2@ti.com> Signed-off-by: NTony Lindgren <tony@atomide.com>

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.

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.

omap_i2c_idle() sets an internal flag, "dev->idle", instructing its ISR to decline interrupts. It sets this flag before it actually masks the interrupts on the I2C controller. This is problematic, since an I2C interrupt could arrive after dev->idle is set, but before the interrupt source is masked. When this happens, Linux disables the I2C controller's IRQ, causing all future transactions on the bus to fail. Symptoms, happening on about 7% of boots: irq 56: nobody cared (try booting with the "irqpoll" option) <warning traceback here> Disabling IRQ #56 i2c_omap i2c_omap.1: controller timed out In omap_i2c_idle(), this patch sets dev->idle only after the interrupt mask write to the I2C controller has left the ARM write buffer. That's probably the major offender. For additional prophylaxis, in omap_i2c_unidle(), the patch clears the dev->idle flag before interrupts are enabled, rather than afterwards. The patch has survived twenty-two reboots on the 3430SDP here without wedging I2C1. Not absolutely dispositive, but promising!

If there is a signal pending and wait_for_completion_interruptible_timeout terminates with -ERESTARTSYS, we return and disable the i2c clocks in omap_i2c_xfer. If we terminate before sending last i2c message with a stop condition, the bus remains busy and we are not able to send new messages into bus with successive omap_i2c_xfer calls. Therefore a pending signal is not caught here and we return only because of timeout or i2c error.

In commit e6bafba5, a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. In particular, the result of !readl(i2c->regs + S3C2410_IICCON) & S3C2410_IICCON_IRQEN is always 0. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E; constant C; @@ ( !E & !C | - !E & C + !(E & C) ) // </smpl> Signed-off-by: NJulia Lawall <julia@diku.dk> Cc: Ben Dooks <ben-linux@fluff.org> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NJean Delvare <khali@linux-fr.org>
