The i2c new register set have new clock divider option for more flexiable generation. And also have separate i2c master and slave register set for control. v4: -fix i2c-ast2600.c driver buffer mode use single buffer conflit in master slave mode both enable. -fix kmemleak issue when use dma mode. -fix typo aspeed,i2c-ast2600.yaml compatible is "aspeed,ast2600-i2c" -fix typo aspeed,i2c-ast2600.ymal to aspeed,i2c-ast2600.yaml v3: -fix i2c global clock divide default value. -remove i2c slave no used dev_dbg info. v2: -add i2c global ymal file commit. -rename file name from new to ast2600. aspeed-i2c-new-global.c -> i2c-ast2600-global.c aspeed-i2c-new-global.h -> i2c-ast2600-global.h i2c-new-aspeed.c -> i2c-ast2600.c -rename all driver function name to ast2600.
