This increment of rmi_smbus in rmi_smb_read/write_block() causes garbage to be read/written. The first read of SMB_MAX_COUNT bytes is fine, but after that it is nonsense. Trial-and-error showed that by dropping the increment of rmiaddr everything is fine and the F54 function properly works. I tried a hack with rmi_smb_write_block() as well (writing to the same F54 touchpad data area, then reading it back), and that suggests that there too the rmiaddr increment has to be dropped. It makes sense that if it has to be dropped for read, then it has to be dropped for write as well. It looks like the initial work with F54 was done using i2c, not smbus, and it seems nobody ever tested F54 with smbus. The other functions all read/write less than SMB_MAX_COUNT as far as I can tell, so this issue was never noticed with non-F54 functions. With this change I can read out the touchpad data correctly on my Lenovo X1 Carbon 6th Gen laptop. Signed-off-by:

F34 is a bit special as it reinitializes the device and related driver structs during the firmware update. This clears the fn_irq_mask which will then prevent F34 from receiving further interrupts, leading to timeouts during the firmware update. Make sure to reinitialize the IRQ enables at the appropriate times. The issue is in F34 code, but the commit in the fixes tag exposed the issue, as before this commit things would work by accident.

The first generation i.MX6 processors does not send an interrupt when the power key is pressed. It sends a power down request interrupt if the key is released before a hard shutdown (5 second press). This should allow software to bring down the SoC safely. For this driver to work as a regular power key with the older SoCs, we need to send a keypress AND release when we get the power down request irq. Signed-off-by:

The driver's method to retrieve the firmware version on ili2117/ ili2118 chip flavours is incorrect. The firmware version register address and layout are wrong. The firmware version is not actually used anywhere inside or outside this driver. There is a dev_dbg() print, but that is only visible when the developer explicitly compiles in debug support. Don't make the code more complicated to preserve a feature that no-one is using. Remove all code associated with chip firmware version. Signed-off-by:

When I2C client is instantiated with I2C_CLIENT_WAKE flag (either via "wakeup-source" device property, or via board info flag), it will mark the main IRQ line as wakeup IRQ, which will ensure that it will be enabled for wakeup when system transitions to suspend state. Since our suspend/resume handlers were only managing IRQ wakeup state, they are no longer needed, and can be removed.

Add support for ILI2117 touch controller. This controller is similar to the ILI210x and ILI251x, except for the following differences: - Reading out of touch data must happen at most 300 mS after the interrupt line was asserted. No command must be sent, the data are returned upon pure I2C read of 43 bytes long. - Supports 10 simultaneous touch inputs. - Touch data format is slightly different. Signed-off-by:

The body of the for loop is only ever run once as the second standard_report element is never changed from its initial zero init, so the loop condition is never satisfies after the first run. Equally the start member of the first element is never changed from 0, so the index offset is always a constant 0. Remove this needless obfuscation of the code and write it in a straight forward manner. Signed-off-by:

We have added polled mode to the normal input devices with the intent of retiring input_polled_dev. This converts kxtj9 driver to use the polling mode of standard input devices and removes dependency on INPUT_POLLDEV. note that with regular input devices handling polling, there is no longer a benefit in having separate INPUT_KXTJ9_POLLED_MODE config option.
