[PATCH] i2c-i801: Fix resume when PEC is used

2006-04-24T16:56:04+00:00

Fix for bug #6395:
Fail to resume on Tecra M2 with ADM1032 and Intel 82801DBM

The BIOS of the Tecra M2 doesn't like it when it has to reboot or
resume after the i2c-i801 driver has left the SMBus in PEC mode.
I have a more complete fix for 2.6.17 but the simple approach of
leaving the SMBus in non-PEC mode after every transaction should do
for -stable. That's what the i2c-i801 driver was doing up to 2.6.15
(inclusive).

[PATCH] i2c: Drop outdated probe/remove code in i2c-isa

2006-02-14T06:30:10+00:00

Probe and remove methods are now defined at bus level. No more need to
redefine them at driver level in i2c-isa.

This lets us get rid of these annoying messages:
Driver 'it87-isa' needs updating - please use bus_type methods

Thanks to Nicolas Mailhot for reporting the problem and testing the fix.

[PATCH] i2c: Use ARRAY_SIZE macro

2006-02-06T20:02:15+00:00

Use ARRAY_SIZE macro instead of sizeof(x)/sizeof(x[0]). Some trailing
whitespaces are also removed.

[ARM] 3237/1: PXA I2C driver updates

2006-01-12T16:30:23+00:00

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 2

2006-01-09T04:47:17+00:00

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.

[PATCH] 1/5 powerpc: Rework PowerMac i2c part 1

2006-01-09T04:47:16+00:00

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

[PATCH] powerpc: Unify udbg (#2)

2006-01-09T03:49:54+00:00

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.
