* i2c: pca-platform: Fix GPIO lookup codeLinus Walleij2019-06-121-2/+1Star
| | | | | | | | | | | | | | | | | The devm_gpiod_request_gpiod() call will add "-gpios" to any passed connection ID before looking it up. I do not think the reset GPIO on this platform is named "reset-gpios-gpios" but rather "reset-gpios" in the device tree, so fix this up so that we get a proper reset GPIO handle. Also drop the inclusion of the legacy GPIO header.

* i2c: acorn: fix i2c warningRussell King2019-06-121-0/+1
| | | | | | | | | | | The Acorn i2c driver (for RiscPC) triggers the "i2c adapter has no name" warning in the I2C core driver, resulting in the RTC being inaccessible. Fix this.

* | i2c: xiic: Add max_read_len quirkRobert Hancock2019-06-081-0/+5
|/ | | | | | | | | | | | | | | | | | This driver does not support reading more than 255 bytes at once because the register for storing the number of bytes to read is only 8 bits. Add a max_read_len quirk to enforce this. This was found when using this driver with the SFP driver, which was previously reading all 256 bytes in the SFP EEPROM in one transaction. This caused a bunch of hard-to-debug errors in the xiic driver since the driver/logic was treating the number of bytes to read as zero. Rejecting transactions that aren't supported at least allows the problem to be diagnosed more easily.

| | | | | | | | | | | | | | | | | | | i2c_new_dummy is typically called from the probe function of the driver for the primary i2c client. It requires calls to i2c_unregister_device in the error path of the probe function and in the remove function. This can be simplified by introducing a device-managed version. Note the changed error case return value type: i2c_new_dummy returns NULL whilst devm_i2c_new_dummy_device returns an ERR_PTR.

Therefore, provide the ability to set the idle state behaviour using a new sysfs file, idle_state as a complement to the method of instantiating the device via sysfs. The possible behaviours are disconnect, i.e. to deselect all channels from the mux, as-is (the default), i.e. leave the last channel selected, and set a predetermined channel. The current behaviour of leaving the channel as-is after each transaction is preserved. Signed-off-by: Robert Shearman <robert.shearman@att.com> Signed-off-by: Peter Rosin <peda@axentia.se>

It can still happen, however if STOP command is not issued on time at the end of the transmission. If wait_for_completion in axxia_i2c_xfer_msg() would not return after 25ms of getting an interrupt, TSS will be generated and idev->err_msg will be set to -ETIMEDOUT which will be returned from the axxia_i2c_xfer_msg(), even though the transfer did actually succeed (STOP is automatically issued when TSS triggers). Fortunately, apart from already used manual and sequence commands, the controller also has so called auto command. It works just like manual mode but it but an automatic STOP is issued when either transfer length is met or NAK is received from slave device. This patch changes the axxia_i2c_xfer_msg() function so that auto command is used for last message in transaction letting hardware manage issuing STOP. TSS is disabled just after command transferring last message finishes. Auto command, just like sequence, ends with SS interrupt instead of SNS so handling of both had to be unified. The axxia_i2c_stop() is no longer needed as the transfer can only end with following conditions: - fully successful - then last message was send by AUTO command and STOP was issued automatically - NAK received - STOP is issued automatically by controller - arbitration lost - STOP should not be issued as we don't control the bus - IP interrupt received - this is sent when transfer length is set to 0 for auto/sequence command. The check for that is done before START is send so no STOP is required - TSS received between commands - STOP is issued by the controller Signed-off-by: Krzysztof Adamski <krzysztof.adamski@nokia.com> Reviewed-by: Alexander Sverdlin <alexander.sverdlin@nokia.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
