- * omap2_sdrc_get_params - return SDRC register values for a given clock rate
- * @r: SDRC clock rate (in Hz)
- * @sdrc_cs0: chip select 0 ram timings **
- * @sdrc_cs1: chip select 1 ram timings **
- *
- * Return pre-calculated values for the SDRC_ACTIM_CTRLA,
- * SDRC_ACTIM_CTRLB, SDRC_RFR_CTRL and SDRC_MR registers in sdrc_cs[01]
- * structs,for a given SDRC clock rate 'r'.
- * These parameters control various timing delays in the SDRAM controller
- * that are expressed in terms of the number of SDRC clock cycles to
- * wait; hence the clock rate dependency.
- *
- * Supports 2 different timing parameters for both chip selects.
- *
- * Note 1: the sdrc_init_params_cs[01] must be sorted rate descending.
- * Note 2: If sdrc_init_params_cs_1 is not NULL it must be of same size
- * as sdrc_init_params_cs_0.
- *
- * Fills in the struct omap_sdrc_params * for each chip select.
- * Returns 0 upon success or -1 upon failure.
