* video: backlight: add slew time parameterLucas Stach2018-06-212-2/+13
| | | | | | | | | | | | Currently the backlight implementation stretches a brightness change over a period of 100ms. While this is a fine default for PWM backlights, a user might wish to change this slew time to meet other constraints or even completely disable it for some backlight devices. Add a parameter and provide the default value from the backlight device. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* nand-bb: mtd_del_bb: fix missing pointer resetHeinrich Toews2018-06-201-0/+2
| | | | | | | | | | | | | If an attached bb device was removed before the actual mtd device the code would try due to a missing pointer reset to access the no more present bb device handle which leads to a page fault. This bug was made visible by commit "7649473 mtd: nand: remove automatically created bb devices" which relys on a correct mtd->cdev_bb handling.

| * | mtd: nand: nand_omap_gpmc: Fix ecc stepsTeresa Remmet2018-05-241-60/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The eccsteps where set wrong for OMAP_ECC_BCH8_CODE_HW_ROMCODE. So the ECC was only corrected for the first 512 bytes chunk of a 2k page. Moved out the ecc step iteration out of the correcting loop to make it more alike the generic nand functions. And made sure that the ECC is caclulated for all chunks. This patch is based on work of Sascha Hauer. Fixes commit dec7b4d2bf9c ("mtd: nand_omap_gpmc: fix BCH error correction").

This causes higher 32 bits of addr to be discarded on a 64 bit system, since flash_info.portwidth is 32 bits long (unsigned int) and addr is 64 bits long (unsigned long).

Barebox does not threat clock providers (such as fixed-clock or gpio-gate-clock) as conventional devices, thus setting default pinctrl configuration in driver binding code does not happen for clock providers. This patch adds setting default pinctrl configuration to of_clk_init(), just before calling clock provider's probe routine.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Depending on specifics, some 'serdev' devices might need prevent parent console device from being removed and corresponding memory deallocated to properly function until the very end of Barebox's execution. An example of such a use-case would be a reset handler relying on a serdev device for transport. To avoid having to develop complicatione reference counting/ownership scheme drop all of the code that calls console_unregister() and frees the memory effectively making the problem above impossible to arise. All of the de-initialization that serial drivers were doing in their .remove functions was somewhat superflous anyway, so this change should be pretty harmless.
