misc: panel: Abstract temporary backlight handling

2017-02-10T14:34:02+00:00

Currently the periodic scan timer is used for three purposes, entangling keypad and display handling, which are both optional: 1. Scanning the keypad, 2. Flashing the backlight when a key is pressed, 3. Disabling temporary backlighting after a fixed period of time. Abstract the second purpose using a new lcd_poke() function. Make the non-periodic temporary backlight handling independent from keypad handling by converting it to a delayed workqueue. Signed-off-by: Geert Uytterhoeven Signed-off-by: Greg Kroah-Hartman

misc: panel: Add lcd_home() helper

2017-02-10T14:32:53+00:00

Add a helper function to move the cursor to the home position, so callers no longer need access to internal state. Signed-off-by: Geert Uytterhoeven Signed-off-by: Greg Kroah-Hartman

misc: panel: Remove always-true check from panel_detach()

misc: panel: Fix LCD_FLAG_F/LCD_FLAG_N exchange

2017-02-10T14:32:53+00:00

LCD_FLAG_F is the font flag, LCD_FLAG_N is the two-lines flag. Signed-off-by: Geert Uytterhoeven Signed-off-by: Greg Kroah-Hartman

misc: panel, convert struct to bitmap

2016-02-12T03:24:23+00:00

There is an anonymous struct which is actually used as a bitmap. So convert the struct to a bitmap and change code accordingly where needed. This also allows for a cleanup of set_data_bits and set_ctrl_bits as they can use a common helper now. The helper can also be converted to a for loop instead of doing bit OR. And given it is a for loop now, bit masking (using BIT_MSK) is moved from the callers there too.
