It's also\nhere if any of the spacemit-ters want to look at what I did to their\ndriver:\nhttps://git.kernel.org/pub/scm/linux/kernel/git/conor/linux.git/log/?h=spacemit-pinctrl\n\nNone of the patches have real commit messages due to this being RFC :)\n\nCheers,\nConor.\n\n* pinmux/pins + functions/groups + functions I think are the only\n really valid combinations here, so it wouldn't be too difficult to\n arrange that logic.\n\nCC: Linus Walleij \nCC: Yixun Lan \nCC: Conor Dooley \nCC: Troy Mitchell \nCC: linux-gpio@vger.kernel.org\nCC: linux-kernel@vger.kernel.org\nCC: linux-riscv@lists.infradead.org\nCC: spacemit@lists.linux.dev\n\nConor Dooley (4):\n pinctrl: generic: change signature of pinctrl_generic_to_map() to pass\n void data\n pinctrl: add new generic groups/function creation function for pinmux\n pinctrl: spacemit: delete check_power()\n pinctrl: spacemit: move over to generic pinmux dt_node_to_map\n implementation\n\n drivers/pinctrl/pinconf.h | 20 +++-\n drivers/pinctrl/pinctrl-generic.c | 139 +++++++++++++++++++++++++-\n drivers/pinctrl/spacemit/pinctrl-k1.c | 70 +++----------\n 3 files changed, 164 insertions(+), 65 deletions(-)"}
