* I2C: OMAP: detect more devices when probing an i2c busNick Thompson2011-04-14-31/+11
| | | | | | | | | | | | | | | | | | | | The omap24xx driver only seems to support devices that have a single subaddress byte. With these types of devices, the first access in a bus transaction is usually a write (writes the subaddress) followed by either a read or write to access the devices registers. Many such devices will respond to a read as the first access, but there are at least some that will NACK such a read. (e.g. ADV7180.) The probe function attempts to detect a devices ACK to a read access only and fails to find devices that NACK a read. This commit modifies the probe function to start a write instead. This detects devices that respond to reads (since they must also respond to writes) as well as those that only respond to writes. The bus is immediately set to idle after a (N)ACK avoiding actually writing anything to the device. Signed-off-by: Nick Thompson <nick.thompson@ge.com>

| * sf: add struct spi_flash.sector_size parameterRichard Retanubun2011-04-12-64/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new member to struct spi_flash (u16 sector_size) and updates the spi flash drivers to start populating it. This parameter can be used by spi flash commands that need to round up units of operation to the flash's sector_size. Having this number in one place also allows duplicated code to be further collapsed into one common location (such as erase parameter and the detected message).
