The patch titled drivers/video/backlight/l4f00242t03.c: fix reset sequence has been removed from the -mm tree. Its filename was drivers-video-backlight-l4f00242t03c-fix-reset-sequence.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: drivers/video/backlight/l4f00242t03.c: fix reset sequence From: Alberto Panizzo <maramaopercheseimorto@xxxxxxxxx> The reset command is part of the init sequence and it take effect only if the lcd is powered. The effect of the bug was that the sequence: set lcd power_state to FB_BLANK_POWERDOWN set lcd power_state to FB_BLANK_UNBLANK Did not produced a complete reboot of the LCD which was showing fuzzy colours. This was not experienced before implementing correctly all the LCD power states with the patch [1]. Since before the patch [1] the regulators were not touched and the LCD shutdown was reached with a register write. After the patch [1] a complete boot sequence with an initial reset is needed for the display every time the LCD is powered up. drivers-video-backlight-l4f00242t03c-full-implement-fb-power-states-for-this-lcd.patch Signed-off-by: Alberto Panizzo <maramaopercheseimorto@xxxxxxxxx> Cc: Richard Purdie <rpurdie@xxxxxxxxx> Cc: Marek Vasut <marek.vasut@xxxxxxxxx> Cc: Tejun Heo <tj@xxxxxxxxxx> Cc: Axel Lin <axel.lin@xxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- drivers/video/backlight/l4f00242t03.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff -puN drivers/video/backlight/l4f00242t03.c~drivers-video-backlight-l4f00242t03c-fix-reset-sequence drivers/video/backlight/l4f00242t03.c --- a/drivers/video/backlight/l4f00242t03.c~drivers-video-backlight-l4f00242t03c-fix-reset-sequence +++ a/drivers/video/backlight/l4f00242t03.c @@ -62,6 +62,8 @@ static void l4f00242t03_lcd_init(struct regulator_enable(priv->core_reg); } + l4f00242t03_reset(pdata->reset_gpio); + gpio_set_value(pdata->data_enable_gpio, 1); msleep(60); spi_write(spi, (const u8 *)cmd, ARRAY_SIZE(cmd) * sizeof(u16)); @@ -227,7 +229,6 @@ static int __devinit l4f00242t03_probe(s } /* Init the LCD */ - l4f00242t03_reset(pdata->reset_gpio); l4f00242t03_lcd_init(spi); priv->lcd_state = FB_BLANK_VSYNC_SUSPEND; l4f00242t03_lcd_power_set(priv->ld, FB_BLANK_UNBLANK); _ Patches currently in -mm which might be from maramaopercheseimorto@xxxxxxxxx are origin.patch linux-next.patch -- To unsubscribe from this list: send the line "unsubscribe mm-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
