One requires setting an RSEL register, which\nhasn't been seen before in U-Boot, so we add a new pinctrl-mtk-common\nfunction to handle this. Then we can fix the mt8189 driver.\n\nFinally, we add some additional debug functionality to print the bias\nregisters when printing out the current pinmux state. This can help with\ndebugging similar issues in the future.\n\nSigned-off-by: David Lechner <dlechner@baylibre.com>\n---\nChanges in v2:\n- Simplified code in \"pinctrl: mediatek: print bias info along with pinmux\"\n- Link to v1: https://patch.msgid.link/20260313-pinctrl-mtk-fix-mt8189-v1-0-607dd37fde37@baylibre.com\n\n---\nDavid Lechner (4):\n pinctrl: mediatek: add handling for RSEL register\n pinctrl: mediatek: mt8189: fix pinconf bias\n pinctrl: mediatek: print bias info along with pinmux\n pinctrl: mediatek: mtk8189: set get_pinconf functions\n\n drivers/pinctrl/mediatek/pinctrl-mt8189.c | 416 ++++++++++++++------------\n drivers/pinctrl/mediatek/pinctrl-mtk-common.c | 105 ++++++-\n drivers/pinctrl/mediatek/pinctrl-mtk-common.h | 7 +\n 3 files changed, 342 insertions(+), 186 deletions(-)\n---\nbase-commit: d9eee3d17882ec40f8ca5e231046bbf287ab4369\nchange-id: 20260313-pinctrl-mtk-fix-mt8189-1f7cf61af74a\n\nBest regards,\n-- \nDavid Lechner <dlechner@baylibre.com>" }
