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.

Gratuitous NULL initializers rarely help and often prevent compiler from warning about using uninitialized variable. Let's remove them.

Add keycode for toggling electronic privacy screen to the keycodes definition. Some new laptops have a privacy screen which can be toggled with a key on the keyboard.

The touchscreen on the Teclast X89 is mounted upside down in relation to the display orientation (the touchscreen itself is mounted upright, but the display is mounted upside-down). Add a quirk for this so that we send coordinates which match the display orientation.

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.

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.
