* i2c-i801: Enable IRQ for SMBus transactionsDaniel Kurtz2012-07-241-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new 'feature' to i2c-i801 to enable using PCI interrupts. When the feature is enabled, then an isr is installed for the device's PCI IRQ. An I2C/SMBus transaction is always terminated by one of the following interrupt sources: FAILED, BUS_ERR, DEV_ERR, or on success: INTR. When the isr fires for one of these cases, it sets the ->status variable and wakes up the waitq. The waitq then saves off the status code, and clears ->status (in preparation for some future transaction). The SMBus controller generates an INTR irq at the end of each transaction where INTREN was set in the HST_CNT register. No locking is needed around accesses to priv->status since all writes to it are serialized: it is only ever set once in the isr at the end of a transaction, and cleared while no interrupts can occur. In addition, the I2C adapter lock guarantees that entire I2C transactions for a single adapter are always serialized. For this patch, the INTREN bit is set only for SMBus block, byte and word transactions, but not for I2C reads or writes. The use of the DS (BYTE_DONE) interrupt with byte-by-byte I2C transactions is implemented in a subsequent patch. The interrupt feature has only been enabled for COUGARPOINT hardware. In addition, it is disabled if SMBus is using the SMI# interrupt. Signed-off-by: Daniel Kurtz <djkurtz@chromium.org> Signed-off-by: Jean Delvare <khali@linux-fr.org>

* i2c-ocores: Can add I2C devices to the busRichard Röjfors2009-06-131-0/+17
| | | | | | | | | | | | | | | | | | There is sometimes a need for the ocores driver to add devices to the bus when installed. i2c_register_board_info can not always be used, because the I2C devices are not known at an early state, they could for instance be connected on a I2C bus on a PCI device which has the Open Cores IP. i2c_new_device can not be used in all cases either since the resulting bus nummer might be unknown. The solution is the pass a list of I2C devices in the platform data to the Open Cores driver. This is useful for MFD drivers.
