* [PATCH] RTC subsystem: I2C cleanupAlessandro Zummo2006-03-27
| | | | | | | | | | | | | This patch, completely optional, removes from drivers/i2c/chips all the drivers that are implemented in the new RTC subsystem. It should be noted that none of the current driver is actually integrated, i.e. usable without further patches.

* [ARM] 3237/1: PXA I2C driver updatesRichard Purdie2006-01-12
| | | | | | | | | | | | | | | | Patch from Richard Purdie This patch adds a check to see if the pxa i2c interface is enabled before allowing it to be used and resets it if found to be disabled. This automatically restores the interface if the device has been suspended and resumed without causing any suspend/resume call ordering issues. The patch also fixes a build warning and adds an appropriate module licence (the module is gpl according to the header).

| * [PATCH] 2/5 powerpc: Rework PowerMac i2c part 2Benjamin Herrenschmidt2006-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the continuation of the previous patch. This one removes the old PowerMac i2c drivers (i2c-keywest and i2c-pmac-smu) and replaces them both with a single stub driver that uses the new PowerMac low i2c layer. Now that i2c-keywest is gone, the low-i2c code is extended to support interrupt driver transfers. All i2c busses now appear as platform devices. Compatibility with existing drivers should be maintained as the i2c bus names have been kept identical, except for the SMU bus but in that later case, all users has been fixed. With that patch added, matching a device node to an i2c_adapter becomes trivial. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * [PATCH] 1/5 powerpc: Rework PowerMac i2c part 1Benjamin Herrenschmidt2006-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the first part of a rework of the PowerMac i2c code. It completely reworks the "low_i2c" layer. It is now more flexible, supports KeyWest, SMU and PMU i2c busses, and provides functions to match device nodes to i2c busses and adapters. This patch also extends & fix some bugs in the SMU driver related to i2c support and removes the clock spreading hacks from the pmac feature code rather than adapting them to the new API since they'll be replaced by the platform function code completely in patch 3/5 Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * [PATCH] powerpc: Unify udbg (#2)Benjamin Herrenschmidt2006-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch unifies udbg for both ppc32 and ppc64 when building the merged achitecture. xmon now has a single "back end". The powermac udbg stuff gets enriched with some ADB capabilities and btext output. In addition, the early_init callback is now called on ppc32 as well, approx. in the same order as ppc64 regarding device-tree manipulations. The init sequences of ppc32 and ppc64 are getting closer, I'll unify them in a later patch. For now, you can force udbg to the scc using "sccdbg" or to btext using "btextdbg" on powermacs. I'll implement a cleaner way of forcing udbg output to something else than the autodetected OF output device in a later patch.

* | [PATCH] IRQ type flagsRussell King2006-01-08
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some ARM platforms have the ability to program the interrupt controller to detect various interrupt edges and/or levels. For some platforms, this is critical to setup correctly, particularly those which the setting is dependent on the device. Currently, ARM drivers do (eg) the following: err = request_irq(irq, ...); set_irq_type(irq, IRQT_RISING); However, if the interrupt has previously been programmed to be level sensitive (for whatever reason) then this will cause an interrupt storm. Hence, if we combine set_irq_type() with request_irq(), we can then safely set the type prior to unmasking the interrupt. The unfortunate problem is that in order to support this, these flags need to be visible outside of the ARM architecture - drivers such as smc91x need these flags and they're cross-architecture. Finally, the SA_TRIGGER_* flag passed to request_irq() should reflect the property that the device would like. The IRQ controller code should do its best to select the most appropriate supported mode.

| * [PATCH] i2c: i2c-mv64xxx fix transaction abortionMark A. Greer2006-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | When the i2c-mv64xxx i2c driver is signalled to abort a transaction, it aborts it immediately by issuing a stop condition on the bus. This violates the i2c protocol and can cause what appears to be an i2c bus hang. This patch delays issuing the stop condition until the i2c device can reasonably expect a stop condition. Also includes a minor fixup. Signed-off-by: Mark A. Greer <mgreer@mvista.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>

In other words, change the client usage count behavior from the old I2C_CLIENT_ALLOW_USE to the old I2C_CLIENT_ALLOW_MULTIPLE_USE.
