On OMAP4 OMAP_I2C_STAT_NACK is causing a timeout on the next access. The isr cleans all flags in OMAP_I2C_CON_REG by setting OMAP_I2C_CON_STP OMAP_I2C_CON_STP is also set in omap_i2c_xfer_msg on the last message. According to the TI TSR the sequence for OMAP_I2C_STAT_NACK and OMAP_I2C_STAT_AL are nearly the same. Removing the OMAP_I2C_CON_STP part in the isr fix the problem. Tested on OMAP4430 and OMAP3530 (here NACK was not a problem) Fixes also booting on 2430sdp.

The i2c-ali1535 driver doesn't work on SPARC, because it assumes that ioport address are 16-bit wide (address stored in an unsigned short). But on SPARC arch, ioports are mapped in memory and so must be stored in an unsigned long. Use pci_resource_start for getting IOMEM base address, then read the SMBBA of the i2c bus and use these together for I/O access. I would like to thank Jean DELVARE for reviewing my patch.

由 Stephen Warren 提交于
One of the Tegra I2C blocks is inside the DVC (Digital Voltage Controller) block. This block is identical to the rest of the I2C blocks, except that it only supports master mode, it has registers moved around, and it needs some extra init to get it into I2C mode. The register moves are handled by i2c_readl and i2c_writel This patch adds a new compatible value for controllers of this "DVC" type; I figured that this approach was reasonable, as opposed to adding an is-dvc property under the existing compatible value, since the HW truly is different. v2: Call of_device_is_compatible() to determine is_dvc, instead of storing the flag in tegra_i2c_of_match[]'s .data field.

Before registering an adapter to i2c subsystem, we need make sure driver is ready for incoming i2c xfer, becasue the i2c_add_adapter() may trigger a i2c device driver's proble function which may start some real i2c xfer.

s3c24xx_i2c_parse_dt_gpio is called when cfg_gpio is not defined in the platform data of the i2c device. When DT is not enabled, the above function always returns -EINVAL.

Double the timeout in the loop which busy-waits for the "master-done" bit to be set. This bit indicates whether an i2c transaction has completed; on the DB1300 and DB1550 boards this timeout is slightly too short and causes transactions to the WM8731 codec to be falsely flagged as failed. The timeout itself is necessary since transactions to non-existant slaves never set this bit in the first place (and cause i2cdetect to hang). With this change the WM8731 codec on the DB1300/DB1550 boards is correctly detected and initialized.
