2011-10-30i2c-algo-bit: Be verbose on bus testing failureJean Delvare1-1/+3
If bus testing fails due to the bus being seen as busy, it might be helpful for developers to know which line is unexpectedly low. Signed-off-by: Jean Delvare <jdelvare@suse.de> Reviewed-by: Alex Deucher <alexdeucher@gmail.com>
2011-10-30i2c-algo-bit: Let user test buses without failingJean Delvare1-3/+3
Always failing to register I2C buses when the line testing fails is a little harsh. While such a failure is definitely a bug in the driver that exposes the affected I2C bus, things may still work fine if the missing initialization steps are done later, before the I2C bus is used. So it seems a better debugging tool to just report the test failure by default. I introduce bit_test=2 if anyone really misses the original behavior of bit_test=1.

2011-10-29i2c-au1550: increase timeout waiting for master doneManuel Lauss1-1/+1
Double the timeout in the loop which busy-waits for the "master-done" bit to be set. This bit indicates whether an i2c transaction has completed; on the DB1300 and DB1550 boards this timeout is slightly too short and causes transactions to the WM8731 codec to be falsely flagged as failed. The timeout itself is necessary since transactions to non-existant slaves never set this bit in the first place (and cause i2cdetect to hang). With this change the WM8731 codec on the DB1300/DB1550 boards is correctly detected and initialized.

2011-10-29I2C: OMAP2+: address confused probed version namingAndy Green1-9/+12
The driver reflects the confusion that probed I2C revision from the hardware of 0x40 means it is on an OMAP4430. However, you will probe the same 0x40 ID on an OMAP3530. So this patch changes the name to reflect that. It also clarifies that the original name OMAP_I2C_REV_2 is referring to some ancient OMAP1 revision number, not to be confused with the IP revisions this patch series introduces. Similarly the term "rev" is used in the ancient OMAP1 ISR, the term is changed to use omap1 instead.

2011-10-29I2C: OMAP2+: Solve array bounds overflow error on i2c idleAndy Green1-1/+1
This solves the main problem the patch series is about. Prior to this patch on OMAP3530 the driver wrongly interprets the I2C peripheral unit's own reported revision as meaning it is running on an IP V2 device and must use the extended registers. In fact OMAP3530 is IP V1 with the smaller register set, the reason for the confusion is that the hardware does in fact report having the same IP revision index as is found on an OMAP4430, which really is IP V2 and has the extended registers. This corrects the test for which registers to use so that it decides using hwmod knowledge found in the platform_data.

2011-10-29I2C: OMAP2+: Name registers in I2C IP V2 only accordinglyAndy Green1-11/+12
The OMAP I2C driver dynamically chooses between two register sets of differing sizes depending on the cpu type it finds itself on. It has been observed that the existing code references non-existing registers on OMAP3530, because while it correctly chose the smaller register layout based on cpu type, the code uses the probed register ID to decide if to execute code referencing an extra register, and both register layout devices on OMAP3530 and OMAP4430 report the same probed ID of 0x40. This patch changes the extended register names only found on IP V2 of the I2C peripheral unit accordingly to help show up errors in usage.

Now that no driver any longer depends on the CONFIG_SOC_AU1??? symbols, it's time to get rid of them: Move some of the platform devices to the boards which can use them, Rename a few (unused) constants in the header, Replace them with MIPS_ALCHEMY in the various Kconfig files. Finally delete them altogether from the Alchemy Kconfig file.

2011-10-24mfd: remove CONFIG_MFD_SUPPORTArnd Bergmann1-1/+0
We currently have two symbols to control compilation the MFD subsystem, MFD_SUPPORT and MFD_CORE. The MFD_SUPPORT is actually not required at all, it only hides the submenu when not set, with the effect that Kconfig warns about missing dependencies when another driver selects an MFD driver while MFD_SUPPORT is disabled. Turning the MFD submenu back from menuconfig into a plain menu simplifies the Kconfig syntax for those kinds of users and avoids the surprise when the menu suddenly appears because another driver was enabled that selects this symbol.
