2007-10-13i2c-nforce2: Declare PEC as supportedJean Delvare1-0/+1
The i2c-nforce2 driver has SMBus PEC support, so it should say so. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-10-13i2c-nforce2: Abort the transaction on errorOleg Ryjkov1-1/+32
This patch is to add an abort function that will bring back the MCP51/55 controller if it was blocked by a block-read operation, in particular. (When a slave sends a wrong byte count on a byte read, the host gets locked up). I've only tested it on an MCP51 and MCP55. However, I'm almost certain it will also work on MCP65, I just did not have the board to test it on. Thus for now the abort function will only be called if an MCP51/55 was detected.

2007-10-13i2c-nforce2: Move status checking to a separate functionOleg Ryjkov1-16/+33
This is the first part of the patch that adds a function to reset the nvidia MCP51/55 i2c controller, if something bad happens to it (e.g. a slave sends a wrong byte count during a block transaction). This patch just adds nforce2_check_status function. It was originally written by Hans-Frieder Vogt. The reason that I'm the one sending it is: - I relied on it for the second part of the patch, - It makes the driver code cleaner/better.

2007-10-13i2c-au1550: Fix a misused register problemChris David1-7/+4
Fix a "mis-used register" problem on the AMD MIPS Alchemy au1550 I2C interface. In summary, the programmable serial controller seems to hang the kernel when I send a single 'address' byte on the I2C bus. The patch essentially uses the PSC_SMBSTAT register's TE (transmit FIFO empty) bit to check when the transmit FIFO is empty, instead of using the PSC_SMBEVNT register's TU (transmit underflow) bit. Using the TE bit fixed the hang problem. Signed-off-by: Chris David <cd@chrisdavid.com> Acked-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-10-13i2c: Rename the PEC functionality bitDavid Brownell2-2/+2
Rename I2C_FUNC_SMBUS_HWPEC_CALC as I2C_FUNC_SMBUS_PEC, and list that functionality as always available through the software implementation. Update documentation accordingly (and list similar requirements). The way it's currently packaged doesn't present the capability in a useful way.

2007-10-13i2c: Remove i2c_algorithm.algo_control()David Brownell2-24/+12
This removes: - An effectively unused hook: i2c_algorithm.algo_control. - The i2c_control() call, used only by i2c-dev to call that unused hook or set two barely supported adapter params. (That param setting moves into i2c-dev.c ... still iffy due to lack of locking, but no other changes.) As shown by diffstat, this is a net code shrink. It also reduces the complexity of the I2C adapter and /dev interfaces. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-10-13i2c: Remove NOP i2c_algorithm.algo_control() methodsDavid Brownell1-8/+0
This removes NOP implementations of i2c_algorithm.algo_control. With this change, there are no implementations of this hook in the kernel.org tree ... that hook seems about ripe to remove.

2007-10-13i2c-dev: Reject I2C_M_RECV_LENDavid Brownell1-2/+4
The I2C_M_RECV_LEN calling convention for i2c_mesg.flags involves playing games with reported buffer lengths. (They start out less than their actual size, and the length is then modified to reflect how many bytes were delivered ... which one hopes is less than the presumed actual size.) Refuse to play such error prone games across the boundary between userspace and kernel.

2007-10-13i2c-stub: Support multiple chipsJean Delvare1-22/+57

2007-10-13i2c/tps65010: New-style driver updates, part 2David Brownell1-146/+38
Switch the tps65010 driver into a "new-style" I2C driver, and convert all of its in-tree users (board support for OSK, H2, H3) accordingly. That accounts for most of the board-specific code in this driver; the rest of that code is now moved into board-specific initcalls. Also remove some of the many now-superfluous #includes.

2007-10-13i2c: New-style devices can support driver model wakeup flagsDavid Brownell1-1/+3
We need to be able to flag I2C devices, such as RTCs, which can issue wake events (usually through IRQ lines). This adds an i2c_board_info.flags bit, and uses it to initialize the i2c device node. (And shrinks a few lines that were overly long.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-10-12Driver core: change add_uevent_var to use a structKay Sievers1-6/+2
This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

2007-09-09i2c-algo-bit: Read block data bugfixDavid Brownell1-20/+32
This fixes a bug in the way i2c-algo-bit handles I2C_M_RECV_LEN, used to implement i2c_smbus_read_block_data(). Previously, in the absence of PEC (rarely used!) it would NAK the "length" byte: S addr Rd [A] [length] NA That prevents the subsequent data bytes from being read: S addr Rd [A] [length] { A [data] }* NA The primary fix just reorders two code blocks, so the length used in the "should I NAK now?" check incorporates the data which it just read from the slave device. However, that move also highlighted other fault handling glitches. This fixes those by abstracting the RX path ack/nak logic, so it can be used in more than one location. Also, a few CodingStyle issues were also resolved. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>

Also, some whitespace fixes to bring this more into sync with the version of this found in the Linux-OMAP tree. (That version has updates for the OTG controller on the OMAP 1710 which break that functionality on OMAP 161x boards like the H2, so merging all of it is not currently an option.)

2007-07-17OMAP: add TI TWL92330/Menelaus Power Management chip driverTony Lindgren3-0/+1292
Add Texas Instruments TWL92330/Menelaus Power Management chip driver. This includes voltage regulators, Dual slot memory card tranceivers and real-time clock(RTC). The support for RTC is integrated with this driver only; it is not separate module. Passes 'rtctest' on OMAP H4 EVM, other than lack of "periodic" (1/N second) IRQs. System wakeup alarms (from suspend-to-RAM) work too. The battery keeps the RTC active over power off, so once you set clock (rdate/ntpdate/etc, then "hwclock -w") then RTC_HCTOSYS at boot time will behave as expected.
