dmaengine: tegra210-adma: add support for Tegra186/Tegra194 Add Tegra186 specific macro defines and chip_data structure for chip specific information. New compatibility is added to select relevant chip details. There is no major change for Tegra194 and hence it can use the same chip data. The bits in the BURST_SIZE field of the ADMA CH_CONFIG register are encoded differently on Tegra186 and Tegra194 compared with Tegra210. On Tegra210 the bits are encoded as follows ... 1 = WORD_1 2 = WORDS_2 3 = WORDS_4 4 = WORDS_8 5 = WORDS_16 Where as on Tegra186 and Tegra194 the bits are encoded as ... 0 = WORD_1 1 = WORDS_2 2 = WORDS_3 3 = WORDS_4 4 = WORDS_5 ... 15 = WORDS_16 Add helper functions for generating the correct burst size.
