backlight: l4f00242t03: Use lcd power constants

2024-09-30T15:49:41+00:00

Replace FB_BLANK_ constants with their counterparts from the lcd subsystem. The values are identical, so there's no change in functionality.

backlight: l4f00242t03: Add check for spi_setup

Add check for the return value of spi_setup() and return the error if it fails in order to catch the error. Signed-off-by: Chen Ni Reviewed-by: Daniel Thompson Link: https://lore.kernel.org/r/20240705092800.3221159-1-nichen@iscas.ac.cn Signed-off-by: Lee Jones

backlight: l4f00242t03: Constify lcd_ops

2024-05-03T09:45:13+00:00

'struct lcd_ops' is not modified by core backlight code, so it can be made const for increased code safety. Signed-off-by: Krzysztof Kozlowski Reviewed-by: Daniel Thompson Link: https://lore.kernel.org/r/20240424-video-backlight-lcd-ops-v2-8-1aaa82b07bc6@kernel.org Signed-off-by: Lee Jones

backlight: l4f00242t03: Simplify with dev_err_probe()

2024-03-07T09:03:29+00:00

Common pattern of handling deferred probe can be simplified with dev_err_probe(). Less code and also it prints the error value.

spi: make remove callback a void function

2022-02-09T13:00:45+00:00

The value returned by an spi driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

backlight: l4f00242t03: Convert to GPIO descriptors

2020-04-29T07:52:15+00:00

This converts the l4f00242t03 backlight driver to use GPIO descriptors and switches the two Freescale i.MX boards over to passing descriptors instead of global GPIO numbers. We use the typical names "enable" and "reset" as found in the device tree bindings for panel GPIOs. This saves a lot of code in the driver and makes it possible to get rid of the platform data header altogether.
