One way to express 12 * these combinations is via the 'ratios' which the clocks operate with 13 * respect to each other. These ratio sets are for a given voltage/DPLL 14 * setting. All configurations can be described by a DPLL setting and a ratio. 15 * 16 * 2430 differs from 2420 in that there are no more phase synchronizers used. 17 * They both have a slightly different clock domain setup. 2420(iva1,dsp) vs 18 * 2430 (iva2.1, NOdsp, mdm) 19 * 20 * XXX Missing voltage data. 21 * XXX Missing 19.2MHz sys_clk rate sets. 22 * 23 * THe format described in this file is deprecated. Once a reasonable 24 * OPP API exists, the data in this file should be converted to use it. 25 * 26 * This is technically part of the OMAP2xxx clock code. 27 */ 28 29 #include <linux/kernel.h> 30 31 #include "opp2xxx.h" 32 #include "sdrc.h" 33 #include "clock.h" 34 35 /* 36 * Key dividers which make up a PRCM set.

There are 42 * quite a few more rate combinations which could be defined. 43 * 44 * When multiple values are defined the start up will try and choose 45 * the fastest one. If a 'fast' value is defined, then automatically, 46 * the /2 one should be included as it can be used. Generally having 47 * more than one fast set does not make sense, as static timings need 48 * to be changed to change the set. The exception is the bypass 49 * setting which is available for low power bypass. 50 * 51 * Note: This table needs to be sorted, fastest to slowest. 52 */ 53 const struct prcm_config omap2430_rate_table[] = { 54 /* PRCM #4 - ratio2 (ES2.1) - FAST */ 55 {S13M, S798M, S399M, R2_CM_CLKSEL_MPU_VAL, /* 399MHz ARM */ 56 R2_CM_CLKSEL_DSP_VAL, R2_CM_CLKSEL_GFX_VAL, 57 R2_CM_CLKSEL1_CORE_VAL, M4_CM_CLKSEL1_PLL_13_VAL, 58 MX_CLKSEL2_PLL_2x_VAL, R2_CM_CLKSEL_MDM_VAL, 59 SDRC_RFR_CTRL_133MHz, 60 RATE_IN_243X}, 61 62 /* PRCM #2 - ratio1 (ES2) - FAST */ 63 {S13M, S658M, S329M, R1_CM_CLKSEL_MPU_VAL, /* 330MHz ARM */ 64 R1_CM_CLKSEL_DSP_VAL, R1_CM_CLKSEL_GFX_VAL, 65 R1_CM_CLKSEL1_CORE_VAL, M2_CM_CLKSEL1_PLL_13_VAL, 66 MX_CLKSEL2_PLL_2x_VAL, R1_CM_CLKSEL_MDM_VAL, 67 SDRC_RFR_CTRL_165MHz, 68 RATE_IN_243X}, 69 70 /* PRCM #5a - ratio1 - FAST */ 71 {S13M, S532M, S266M, R1_CM_CLKSEL_MPU_VAL, /* 266MHz ARM */ 72 R1_CM_CLKSEL_DSP_VAL, R1_CM_CLKSEL_GFX_VAL, 73 R1_CM_CLKSEL1_CORE_VAL, M5A_CM_CLKSEL1_PLL_13_VAL, 74 MX_CLKSEL2_PLL_2x_VAL, R1_CM_CLKSEL_MDM_VAL, 75 SDRC_RFR_CTRL_133MHz, 76 RATE_IN_243X}, 77 78 /* PRCM #5b - ratio1 - FAST */ 79 {S13M, S400M, S200M, R1_CM_CLKSEL_MPU_VAL, /* 200MHz ARM */ 80 R1_CM_CLKSEL_DSP_VAL, R1_CM_CLKSEL_GFX_VAL, 81 R1_CM_CLKSEL1_CORE_VAL, M5B_CM_CLKSEL1_PLL_13_VAL, 82 MX_CLKSEL2_PLL_2x_VAL, R1_CM_CLKSEL_MDM_VAL, 83 SDRC_RFR_CTRL_100MHz, 84 RATE_IN_243X}, 85 86 /* PRCM #4 - ratio1 (ES2.1) - SLOW */ 87 {S13M, S399M, S199M, R2_CM_CLKSEL_MPU_VAL, /* 200MHz ARM */ 88 R2_CM_CLKSEL_DSP_VAL, R2_CM_CLKSEL_GFX_VAL, 89 R2_CM_CLKSEL1_CORE_VAL, M4_CM_CLKSEL1_PLL_13_VAL, 90 MX_CLKSEL2_PLL_1x_VAL, R2_CM_CLKSEL_MDM_VAL, 91 SDRC_RFR_CTRL_133MHz, 92 RATE_IN_243X}, 93 94 /* PRCM #2 - ratio1 (ES2) - SLOW */ 95 {S13M, S329M, S164M, R1_CM_CLKSEL_MPU_VAL, /* 165MHz ARM */ 96 R1_CM_CLKSEL_DSP_VAL, R1_CM_CLKSEL_GFX_VAL, 97 R1_CM_CLKSEL1_CORE_VAL, M2_CM_CLKSEL1_PLL_13_VAL, 98 MX_CLKSEL2_PLL_1x_VAL, R1_CM_CLKSEL_MDM_VAL, 99 SDRC_RFR_CTRL_165MHz, 100 RATE_IN_243X}, 101 102 /* PRCM #5a - ratio1 - SLOW */ 103 {S13M, S266M, S133M, R1_CM_CLKSEL_MPU_VAL, /* 133MHz ARM */ 104 R1_CM_CLKSEL_DSP_VAL, R1_CM_CLKSEL_GFX_VAL, 105 R1_CM_CLKSEL1_CORE_VAL, M5A_CM_CLKSEL1_PLL_13_VAL, 106 MX_CLKSEL2_PLL_1x_VAL, R1_CM_CLKSEL_MDM_VAL, 107 SDRC_RFR_CTRL_133MHz, 108 RATE_IN_243X}, 109 110 /* PRCM #5b - ratio1 - SLOW*/ 111 {S13M, S200M, S100M, R1_CM_CLKSEL_MPU_VAL, /* 100MHz ARM */ 112 R1_CM_CLKSEL_DSP_VAL, R1_CM_CLKSEL_GFX_VAL, 113 R1_CM_CLKSEL1_CORE_VAL, M5B_CM_CLKSEL1_PLL_13_VAL, 114 MX_CLKSEL2_PLL_1x_VAL, R1_CM_CLKSEL_MDM_VAL, 115 SDRC_RFR_CTRL_100MHz, 116 RATE_IN_243X}, 117 118 /* PRCM-boot/bypass */ 119 {S13M, S13M, S13M, RB_CM_CLKSEL_MPU_VAL, /* 13Mhz */ 120 RB_CM_CLKSEL_DSP_VAL, RB_CM_CLKSEL_GFX_VAL, 121 RB_CM_CLKSEL1_CORE_VAL, MB_CM_CLKSEL1_PLL_13_VAL, 122 MX_CLKSEL2_PLL_2x_VAL, RB_CM_CLKSEL_MDM_VAL, 123 SDRC_RFR_CTRL_BYPASS, 124 RATE_IN_243X}, 125 126 /* PRCM-boot/bypass */ 127 {S12M, S12M, S12M, RB_CM_CLKSEL_MPU_VAL, /* 12Mhz */ 128 RB_CM_CLKSEL_DSP_VAL, RB_CM_CLKSEL_GFX_VAL, 129 RB_CM_CLKSEL1_CORE_VAL, MB_CM_CLKSEL1_PLL_12_VAL, 130 MX_CLKSEL2_PLL_2x_VAL, RB_CM_CLKSEL_MDM_VAL, 131 SDRC_RFR_CTRL_BYPASS, 132 RATE_IN_243X}, 133 134 { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, 135 }; 136
