[1] This time only a small fix, spotted by Jernej, thanks for that. Also adding the new tags. Changelog below. ============== The first four patches extend the sunxi pinctrl core code to deal with some specialities of the new SoC: it uses every of the 11 possible banks except the first one, which required some register remapping. The first patch here is some cleanup, which we should take regardless, I think, since it fixes some hack we introduced with the D1 support. The main feature is actually patch 5, which introduces a new way to express the required pinmux values for each function/pin pair. Traditionally, we dumped a rather large table of data into the (single image!) kernel for that, but this approach now puts that value into the DT, and builds the table at runtime. This patch was posted twice before [2][3], the last time LinusW seemed to be fine with the idea, just complained about the abuse of the generic pinmux property. I changed that to allwinner,pinmux now. The rest of the patches are the usual suspects: the two files for the two pinctrl instances of the new SoC (now very small), and the DT binding. Based on v6.14-rc1. Please have a look, review and test!
