From: Tomasz Unger <[email protected]> fsleep() is the preferred modern API for flexible sleeping as it automatically selects the best sleep mechanism based on the duration. Replace udelay() with fsleep() to improve power efficiency.
init_display() is a driver initialization callback which runs in sleeping context, so fsleep() is safe to use here. Signed-off-by: Tomasz Unger <[email protected]> --- Changes in v2: - Added sleeping context justification to commit message - Replaced usleep_range() with fsleep() as suggested by Andy Shevchenko drivers/staging/fbtft/fb_tinylcd.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/staging/fbtft/fb_tinylcd.c b/drivers/staging/fbtft/fb_tinylcd.c index 9469248f2c50..3fb15df31592 100644 --- a/drivers/staging/fbtft/fb_tinylcd.c +++ b/drivers/staging/fbtft/fb_tinylcd.c @@ -41,7 +41,7 @@ static int init_display(struct fbtft_par *par) 0x00, 0x35, 0x33, 0x00, 0x00, 0x00); write_reg(par, MIPI_DCS_SET_PIXEL_FORMAT, 0x55); write_reg(par, MIPI_DCS_EXIT_SLEEP_MODE); - udelay(250); + fsleep(250); write_reg(par, MIPI_DCS_SET_DISPLAY_ON); return 0; -- 2.53.0
