由 Wolfgang Grandegger 提交于
This patch makes the I2C bus speed configurable by using the I2C node property "clock-frequency". If the property is not defined, the old fixed clock settings will be used for backward comptibility. The generic I2C clock properties, especially the CPU-specific source clock pre-scaler are defined via the OF match table: static const struct of_device_id mpc_i2c_of_match[] = { ... {.compatible = "fsl,mpc8543-i2c", .data = &(struct fsl_i2c_match_data) { .setclock = mpc_i2c_setclock_8xxx, .prescaler = 2, }, }, The "data" field defines the relevant I2C setclock function and the relevant pre-scaler for the I2C source clock frequency. It uses arch-specific tables and functions to determine resonable Freqency Divider Register (fdr) values for MPC83xx, MPC85xx, MPC86xx, MPC5200 and MPC5200B. The i2c->flags field and the corresponding FSL_I2C_DEV_* definitions have been removed as they are obsolete.

The platform data for the i2c-s3c2410 driver used to allow a min, max and desired frequency for the I2C bus. This patch reduces it to simply a desired frequency ceiling and corrects all the uses of the platform data appropriately. This means, for example, that on a system with a 66MHz fclk, a request for 100KHz will achieve 65KHz which is safe and acceptable, rather than 378KHz which it would have achieved without this change.

There are various bits of code here that are unfinished and instead of being harmless either confuse or spew stuff into the logs at higher than debug level. They can and should go away. Also remove the bogus use of tty->lowlatency. We fixed the need for this hack long ago (with the flip buffer rewrite) but people keep copying it into drivers.

mxser_check_modem_status is called with tty parameter, so the reference should be increased by callers already -- for ioctl syscall it is held whole time gap since open to close, for interrupt, the reference count is increased in the irq handler. There is no tty_kref_put in that function, so this also fixes a refcounting bug.
