Because of OMAP off-mode, powerdomain can go off when I2C is idle. Save enough state, and do a re-init for each transfer. Additional save/restore state added by Jagadeesh Bhaskar Pakaravoor (SYSC_REG) and Aaro Koskinen (wakeup sources.) Also, The OMAP3430 TRM states: "During active mode (I2Ci.I2C_CON[15] I2C_EN bit is set to 1), make no changes to the I2Ci.I2C_SCLL and I2Ci.I2C_SCLH registers. Changes may result in unpredictable behavior." Hence, the I2C_EN bit should be clearer when modifying these registers. Please note that clearing the entire I2C_CON register to disable the I2C module is safe, because the I2C_CON register is re-configured for each transfer. Signed-off-by:

In the case of no-ACKs, we don't want to see dev_err() messages in the console, because some utilities like i2c-tools are capable of printing decorated console output. This patch will ease such situations. Signed-off-by:

Suppose TX_ABRT occurs in the middle of processing i2c_msg msgs[], and a STOP condition has already been generated on the bus. In this case, subsequent i2c_dw_xfer_msg() might initiate a new and unnecessary I2C transaction, which we'd have to avoid. Furthermore, anytime TX_ABRT is set, the contents of tx/rx buffers are flushed, so we don't have to process RX_FULL and TX_EMPTY. Disable interrupts, and skip them. Signed-off-by:

Current error handling procedures are not good in two respects: * Forgot to mark dev->cmd_complete as "completed" on errors Once an I2C transaction is initiated, wait_for_completion_ interruptible_timeout() waits for dev->cmd_complete to be completed. We have to take care of it whenever an error is detected, otherwise we will have a needless HZ timeout. * Forgot to disable interrupts In the previous patch, interrupt mask operations have been changed. We don't disable interrupts at the end of the interrupt handler any more, and try to keep RX_FULL (and TX_EMPTY if required) enabled during the transaction so that we can send longer data than the size of Tx/Rx FIFO. If an error is detected, we need to disable interrupts before quitting current transaction. We can work around above points using dev->msg_err effectively. Signed-off-by:

Currently we disable TX_EMPTY interrupt when buf_len is zero, but this is wrong. (buf_len == 0) means that all transmit data in the current i2c_msg message has been sent out, but that doesn't necessarily mean all i2c_msg messages have been processed. TX_EMPTY interrupt is used as the driving force of DW I2C transactions, so we need to keep it enabled as long as i2c_msg messages are available. Signed-off-by:

Currently we process the first i2c_dw_xfer_msg() in i2c_dw_xfer(), but in this case there is a possibility to be interrupted by certain interrupts. As described before in this patchset, we need to keep providing new transmit data within a given time period, otherwise Tx FIFO underrun takes place and STOP condition will be generated on the bus, even if we have more bytes to be written. In order to exclude all such possibilities, change TX_EMPTY interrupt usage as below: * DW_IC_INTR_DEFAULT_MASK: Define a default interrupt mask set, and put TX_EMPTY there. * i2c_dw_xfer_init: Enable DW_IC_INTR_DEFAULT_MASK prior to initiating a new I2C transaction. The first TX_EMPTY will be triggered shortly. With the help of it, we can make the first call to i2c_dw_xfer_msg() in the interrupt handler. * i2c_dw_xfer_msg: Fixup intr_mask operation accordingly. Make sure that TX_EMPTY operations need to be reversed. * request_irq: Set IRQF_DISABLED so that we could load transmit data into Tx FIFO without being distracted by other interrupts. * Remove i2c_dw_xfer_msg() in i2c_dw_xfer().

I2c_dw_xfer_msg() also has the same target address inconsistency check, and furthermore it checks across all i2c_msg messages, while i2c_dw_read() walks through i2c_msg messages only with_ I2C_M_RD flag. That is, target address check in i2c_dw_read() is redundant and useless. Signed-off-by:

While we have a local variable "buf_len" for dev->tx_buf_len, we don't have such local variable for dev->tx_buf pointer. While "buf_len" is restored at first then updated when we start processing a new i2c_msg (determined by STATUS_WRITE_IN_PROGRESS flag), ->tx_buf is different. Such inconsistency makes the code slightly hard to follow. Signed-off-by:

We have some steps at the top of i2c_dw_xfer_msg() to set up a slave address and enable DW I2C core. And it's executed only when we don't have STATUS_WRITE_IN_PROGRESS. But we need to make sure that STATUS_WRITE_IN_PROGRESS only indicates that we have a pending i2c_msg to process. In other words, even if STATUS_WRITE_IN_PROGRESS is not set, that doesn't mean we're at initial state in the I2C transaction. Since i2c_dw_xfer_msg() will be invoked again and again during a transaction, those init steps have a possibility to be re-processed needlessly. For example, this issue easily takes place when processing a combined transaction with a certain condition (the number of tx bytes in the first i2c_msg, equals to the Tx FIFO depth). Consequently we should not use STATUS_WRITE_IN_PROGRESS to determine where we're at in an I2C transaction. It would be better to separate those initialization steps from i2c_dw_xfer_msg().

As a hardware feature, DW I2C core generates a STOP condition whenever the Tx FIFO becomes empty (strictly speaking, whenever the last byte in the Tx FIFO is sent out), even if we have more bytes to be written. In other words, we must never make "Tx FIFO underrun" happen during a transaction, except for the last byte. For the safety's sake, we'd make TX_EMPTY interrupt get triggered every time one byte is processed. The Rx FIFO threshold needs to be set as well. Signed-off-by:

Symptom: -------- When we're going to send/receive the longer size of data than the Tx FIFO length, the I2C transaction will be divided into several separated transactions, limited by the Tx FIFO length. Details: -------- As a hardware feature, DW I2C core generates a STOP condition whenever the Tx FIFO becomes empty (strictly speaking, whenever the last byte in the Tx FIFO is sent out), even if we have more bytes to be written. Then, once a new transmit data is written to the Tx FIFO, DW I2C core will initiate a new transaction, which leads to another START condition. This explains how the transaction in question goes, and implies that current tasklet-based dw_i2c_pump_msg() strategy couldn't meet the timing constraint required for avoiding Tx FIFO underrun. To avoid this scenario, we must keep providing new transmit data within a given time period. In case of Fast-mode + 32-byte Tx FIFO, for instance, it takes about 22.5[us] to process single byte, and 720[us] in total. This patch removes the existing tasklet-based "pump" system, and move its jobs into the interrupt handler. Signed-off-by:

In case a work-in-progress i2c_msg has more bytes to be written, we need to set STATUS_WRITE_IN_PROGRESS and exit from the msg_write_idx- searching loop. Otherwise, we will overtake the current msg_write_idx without waiting for its transmission to be processed. Signed-off-by:

* Calculate with accurate conditional expressions from DW manuals. * Round ic_clk by adding 0.5 as it's important at high ic_clk rate. * Take into account "tHD;STA" issue for _HCNT calculation. * Take into account "tf" for _LCNT calculation. * Add "cond" and "offset" fot further correction requirements. For _HCNT calculation, there's one issue needs to be carefully considered; DesignWare I2C core doesn't seem to have solid strategy to meet the tHD;STA timing spec. If you configure _HCNT based on the tHIGH timing spec, it easily results in violation of the tHD;STA spec. After many trials, we came to the conclusion that the tHD;STA period is proportional to (_HCNT + 3). For the safety's sake, this should be selected by default. As for _LCNT calculation, DW I2C core has one characteristic behavior; he starts counting the SCL CNTs for the LOW period of the SCL clock (tLOW) as soon as it pulls the SCL line. At that time, he doesn't take into account the fall time of SCL signal (tf), IOW, he starts counting CNTs without confirming the SCL input voltage has dropped to below VIL. This characteristics becomes a problem on some platforms where tf is considerably long, and results in violation of the tLOW timing spec. To make the driver configurable as much as possible for various cases, we'd have separated arguments "tf" and "offset", and for safety default values should be 0.3 us and 0, respectively.
