Detailed Description

Backlight driver operations, called with the device lock held.

Field Documentation

get_level

uint8_t(* pbl_backlight_ops::get_level) (const struct pbl_backlight *bl, uint8_t brightness)

Optional.

Map a brightness to a hardware level identifier, for drivers with fewer levels than brightness steps.

init

int(* pbl_backlight_ops::init) (const struct pbl_backlight *bl)

Bring the hardware up.

Returns 0, -ENODEV if the part does not answer, or a negative errno.

refresh

int(* pbl_backlight_ops::refresh) (const struct pbl_backlight *bl)

Optional.

Re-apply the state to the hardware.

set_brightness

int(* pbl_backlight_ops::set_brightness) (const struct pbl_backlight *bl, uint8_t brightness)

Apply brightness; the state still holds the previous one.

set_color

int(* pbl_backlight_ops::set_color) (const struct pbl_backlight *bl, uint32_t rgb_color)

Optional.

Apply rgb_color; the state still holds the previous one.
