MediaTek clock reset driver is used to provide reset control of modules controlled in clk, like infra_ao. Changes for V5: 1. Add all infra reset bits for MT8192 and MT8195. 2. Fix reviewers' comments. Changes for V4: 1. Abandon the implementation of reset-cell = 2, and use reset index to determine which reset bit is used. 2. Add documentation for enum/structure/function in reset.h. 3. Combine binding/drvier support patch for MT8192 and MT8195. 4. The MT8195 DTS is accepted by Matthias, and I add new DTS patch to support infracfg_ao reset for MT8195. The DTS of MT8195 is still not merged into mainline. Please refer to [1].

Modify drivers for reviewers' comments. 2. Add dt-binding patch for MT8192/MT8195 infra. 3. Add reset property of infra node for MT8192. 4. Use original function for simple operation. Changes for V2: 1. Modify drivers for reviewers' comments. 2. Use simple reset to replace v1. 3. Recover v2 to set_clr. 4. Separate error handling to another patch. 5. Add support for input offset and bit from DT. 6. Add support for MT8192 and MT8195.
