[PATCH] tools: docker: Drop the git user name and email configuration

[PATCH] pinctrl: mediatek: Bind gpio while binding pinctrl
by Chris Webb 08 Oct '24

08 Oct '24

Mediatek pinctrl drivers call mtk_gpiochip_register() to bind the child gpio controller as part of mtk_pinctrl_common_probe(). This breaks gpiohog support because the gpio controller is bound too late for DM_FLAG_PROBE_AFTER_BIND (set while binding hogs) to work. Move the mtk_gpiochip_register() to mtk_pinctrl_common_bind() and call this as the .bind method of each of the mediatek pinctrl drivers.

[PATCH v2 0/4] dm: core: fix several debug messages and migrate debug() to dm_warn
by Quentin Schulz 03 Oct '24

03 Oct '24

Fix a few misleading or incorrect debug messages and prompt text for a Kconfig symbol. Migrate debug() messages to use dm_warn() instead so that we can print them without selecting DM_DEBUG which does too much (e.g. makes assert() reset U-boot if it fails). Tested on top of next branch but it applies without complaints on top of master as well, so up to you to which branch to merge it.
