No. Not available in public. I got the datasheet because Socionext (formerly, Panasonic) bought this IP. > Mine clearly states that the factor is 4. > "The frequency of nand_x_clk is four times the frequency of nand_clk." I checked "Denali NAND Flash Memory Controller User's Guide" released by Denali. I also get access to a newer version "Cadence Design IP - NAND Flash Memory Controller User's Guide" because Cadence acquired Denali. My datasheet says: "clk_x - Cadence NAND Flash Memory Controller bus interface clock. This runs at a configured multiple of clk as is phase aligned. Configured multiple can be between 4-6 times." Various parts of this IP are configurable. Is yours talking about this IP, or about a particular configuration for SOCFPGA? >> To not break the existing platforms, the fallback value, 50 MHz is >> provided.

This commit improves the ->setup_data_interface() hook. The denali_setup_data_interface() needs the frequency of clk_x and the ratio of clk_x / clk. The latter is currently hardcoded in the driver, like this: #define DENALI_CLK_X_MULT 6 The IP datasheet requires that clk_x / clk be 4, 5, or 6. I just chose 6 because it is the most defensive value, but it is not optimal. By getting the clock rate of both "clk" and "clk_x", the driver can compute the timing values more precisely. To not break the existing platforms, the fallback value, 50 MHz is provided. It is true for all upstreamed platforms.
