Hi,
Here are 2 important fixes and a code improvement to the T-Head TH1520
pinctrl driver that was either introduced or missed when Drew took over
upstreaming it.
It is based on Linus' pinctrl/for-next:
6dbd1577b7dc ("Merge branch 'devel' into for-next")
Emil Renner Berthing (3):
pinctrl: th1520: Fix pinconf return values
pinctrl: th1520: Update pinmux tables
pinctrl: th1520: Factor out casts

* [PATCH v1 2/3] pinctrl: th1520: Update pinmux tables @ 2024-10-11 14:48 ` Emil Renner Berthing 0 siblings, 0 replies; 23+ messages in thread From: Emil Renner Berthing @ 2024-10-11 14:48 UTC (permalink / raw) To: linux-kernel, linux-gpio, devicetree, linux-riscv Cc: Linus Walleij, Jisheng Zhang, Guo Ren, Fu Wei, Paul Walmsley, Palmer Dabbelt, Thomas Bonnefille When Drew took over the pinctrl driver it seems like he didn't use the git tree I pointed him at and thus missed some important fixes to the tables describing valid pinmux settings. The documentation has a nice overview table of these settings but unfortunately it doesn't fully match the register descriptions, which seem to be the correct version.
