2012-07-24i2c-i801: Rename some SMBHSTCNT bit constantsDaniel Kurtz
Rename the SMBHSTCNT register bit access constants to match the style of other register bits. Signed-off-by: Daniel Kurtz <djkurtz@chromium.org> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2012-07-24i2c-i801: Check and return errors during byte-by-byte transfersDaniel Kurtz
If an error is detected in the polling loop, abort the transaction and return an error code. * DEV_ERR is set if the device does not respond with an acknowledge, and the SMBus controller times out (minimum 25ms). * BUS_ERR is set if a bus arbitration collision is detected. In other words, when the SMBus controller tries to generate a START condition, but detects that the SMBDATA is being held low, usually by another SMBus/I2C master. * FAILED is only set if a transaction is stopped by software (using the SMBHSTCNT KILL bit).

2012-07-24i2c-i801: Clear only status bits in HST_STSDaniel Kurtz
Writing back the whole status register could clear unwanted bits. In particular, it could clear the "INUSE_STS" bit, which is a 'hardware semaphore', that might be useful to use some day. To prepare for this, let's ban writing back the whole status to register HST_STS, of which this is the only instance.

2012-07-24i2c-i801: Refactor use of LAST_BYTE in i801_block_transaction_byte_by_byteDaniel Kurtz
As a slight optimization, pull some logic out of the polling loop during byte-by-byte transactions by just setting the I801_LAST_BYTE bit, as defined in the i801 (PCH) datasheet, when reading the last byte of a byte-by-byte I2C_SMBUS_READ.

2012-07-24i2c-piix4: Support AMD auxiliary SMBus controllerAndrew Armenia
Some AMD chipsets, such as the SP5100, have an auxiliary SMBus controller with a second set of registers. This patch adds support for this auxiliary controller. Tested on ASUS KCMA-D8 motherboard.

2012-07-24i2c-piix4: Separate registration and probing codeAndrew Armenia
Some chipsets have multiple sets of SMBus registers each controlling a separate SMBus. Supporting these chipsets properly will require registering multiple I2C adapters for one piix4. The code to initialize and register the i2c_adapter structure has been separated from piix4_probe and allows registration of a piix4 adapter given its base address. Note that the i2c_adapter and i2c_piix4_adapdata structures are now dynamically allocated. Signed-off-by: Andrew Armenia <andrew@asquaredlabs.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2012-07-24i2c-piix4: Eliminate piix4_smba global variableAndrew Armenia
Some chipsets have multiple sets of piix4-compatible SMBus registers. Eliminating the global variable will allow these chipsets to be fully supported. Return value from piix4_setup and piix4_sb800_setup now returns the smba value detected. This is stored in a struct i2c_piix4_adapdata. Thus the global variable is eliminated.
