由 Ionut Nicu 提交于
The i2c-mux driver requires that the chan_id parameter passed to the i2c_add_mux_adapter() function is equal to the reg value for that adapter: for_each_child_of_node(mux_dev->of_node, child) { ret = of_property_read_u32(child, "reg", ®); if (ret) continue; if (chan_id == reg) { priv->adap.dev.of_node = child; break; } } The i2c-mux-gpio driver uses an internal logical index for chan_id when calling i2c_add_mux_adapter() instead of using the reg value. Because of this, there will problems in selecting the right adapter when the i2c-mux-gpio's index into mux->data.values doesn't match the reg value. An example of such a case: mux->data.values = { 1, 0 } For chan_id = 0, i2c-mux will bind the adapter to the of_node with reg = <0>, but when it will call the select() callback with chan_id set to 0, the i2c-mux-gpio will use it as an index into mux->data.values and it will actually select the bus with reg = <1>.

The i.MX23 I2C controller is also capable of PIO, but needs a little harder push to behave. The controller needs to be reset after every PIO/DMA operation for some reason, otherwise in rare cases, the controller can hang or emit bytes onto the bus.

Analyze and rework the PIO mode operation. The PIO mode operation was unreliable on MX28, by analyzing the bus with LA, the checks for when data were available or were to be sent were wrong. The PIO WRITE has to be completely reworked as it multiple problems. The MX23 datasheet helped here, see comments in the code for details. The problems boil down to: - RUN bit in CTRL0 must be set after DATA register was written - The PIO transfer must be 4 bytes long tops, otherwise use clock stretching. Both of these fixes are implemented. The PIO READ operation can only be done for up to four bytes as we are unable to read out the data from the DATA register fast enough. This patch also tries to document the investigation within the code. Signed-off-by: NMarek Vasut <marex@denx.de> Signed-off-by: NWolfram Sang <wsa@the-dreams.de>

由 Lars-Peter Clausen 提交于
The 'driver' field of the i2c_client struct is redundant. The same data can be accessed through to_i2c_driver(client->dev.driver). The generated code for both approaches in more or less the same. E.g. on ARM the expression client->driver->command(...) generates ... ldr r3, [r0, #28] ldr r3, [r3, #32] blx r3 ... and the expression to_i2c_driver(client->dev.driver)->command(...) generates ... ldr r3, [r0, #160] ldr r3, [r3, #-4] blx r3 ... Other architectures will generate similar code. All users of the 'driver' field outside of the I2C core have already been converted. So this only leaves the core itself. This patch converts the remaining few users in the I2C core and then removes the 'driver' field from the i2c_client struct.

Using the same clock for all device instances is non-portable and obtaining clock references by an ID without using a device pointer is discouraged. This is also not needed, because on platforms, where this driver is used, suitable clocks are available for the I2C controllers, that are children of the peripheral clock and just pass its rate 1-to-1 to controllers.
