v6: Add the judgment condition, clear the handshake signal between dma and i2c when multiple msgs are transmitted. v5: 1. Replace the previous variable name "default_timing_adjust" with "use-default-timing" 2. Added waiting for dma reset mechanism 3. Remove received patch(dt-bindings: i2c: update bindings for MT8195 SOC) v4: 1. Remove the repeated assignment of the inter_clk_div parameter 2. Modify the wrong assignment of OFFSET_MULTI_DMA 3. Unify the log print format of the i2c_dump_register() and drop the extra outer parentheses 4. Place the fixes at the very least 5. Add fixed tags 25708278f810 ("i2c: mediatek: Add i2c support for MediaTek MT8183") 6. Add "i2c: mediatek: modify bus speed calculation formula" 7. Fix single line characters exceeding 80 characters 8. Combine two different series of patches. v3: 1. Fix code errors caused by v2 modification v2: 1. Add "dt-bindings: i2c: add attribute default-timing-adjust" 2. Split the fix into sepatate patch.
