Gerard Marull-Paretas 071b80290c drivers: kscan: ft5336: simplify device definition 
Use the IF_ENABLED macro helper to conditionally initialize the int_gpio
field. This avoids duplication of initialization code.

Tomasz Bursztyka e18fcbba5a device: Const-ify all device driver instance pointers 
Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

A coccinelle rule is used for this:

@r_const_dev_1
  disable optional_qualifier
@
@@
-struct device *
+const struct device *

@r_const_dev_2
 disable optional_qualifier
@
@@
-struct device * const
+const struct device *

Fixes #27399

Gerard Marull-Paretas ca9dce0d7d drivers: kscan: generalize and improve FT5336 driver 
The FT5336 driver has been improved and generalized so that multiple
Focaltech touch controllers can be supported using the same single
driver. According to specifications the following list of controller
variants should be supported: FT5x06, FT5606, FT5x16, FT6x06, Ft6x36,
FT5x06i, FT5336, FT3316, FT5436i, FT5336i and FT5x46.

Tested using ER-TFTM028-4 display module (FT6X06).

Maureen Helm 6382f06aa0 drivers: kscan: Introduce ft5336 touch panel driver 
Introduces a new ft5336 touch panel driver for the keyboard scan (kscan)
interface. The driver currently uses a timer to periodically poll touch
data in the system work queue, but later it can be enhanced to use a
gpio interrupt instead of a timer.
