Straight off the bat, I'm fixing the ABI that I broke a while back, by reintroducing the ralink,rt2880-pinmux compatible string. If you take a look at the schema for mt7620 and rt305x, some functions got multiple lists for groups. Like refclk on mt7620. Because mt7620 and mt7628/mt7688 SoCs use the same compatible string, it's impossible to differentiate on the binding which SoC a devicetree is actually for. Therefore, the binding will allow all groups listed for that function. For example, if the SoC is mt7620, only the refclk function for the mdio group can be used. If one were to put "spi cs1" as the function there, there wouldn't be a warning. I address this by introducing new compatible strings for these SoCs, then split the schemas. I also separate mt7628/mt7688 from mt7620 pinctrl subdriver in the process. I wanted to split the rt305x driver too but too much code would be reused so I backed down from that. This platform from Ralink was acquired by MediaTek in 2011. Then, MediaTek introduced new SoCs which utilise this platform. We're moving the Ralink pinctrl driver to MediaTek, and rename the schemas for MediaTek SoCs to mediatek. I've renamed the ralink core driver to mtmips. I decided to call the core mtmips as I've seen folks from MediaTek use the same name when they added support for MT7621 pinctrl on U-Boot. Feel free to comment on this. Arınç v3: - Address Rob's indentation report. - Add Rob's reviewed-by. - Rebase to linusw/linux-pinctrl.git devel. v2: - Address Rob and Krzysztof's reviews, add Rob's acked-by. - More more cleanups, hooray! - Don't add new mediatek compatible strings, we don't do that here. RIP Chadwick Boseman. - Don't deprecate ralink,mt7620-pinctrl, we need it now. - More slight changes I can't currently remember to mention. RFC to v1: - Address Rob and Krzysztof's reviews, add Rob's acked-by. - More cleanups, hooray! - Keep ralink,rt2880-pinmux deprecated. - Deprecate ralink,mt7620-pinctrl. Another one bites the dust! - More slight changes I can't currently remember to mention.
