The clock ID is directly mapped to the 15 corresponding clock gating control bit in HW to ease manual clock lookup in 16 datasheet. 17 18 The following is a list of provided IDs for Armada 370: 19 20 ID Clock Peripheral 21 ----------------------------------- 22 0 Audio AC97 Cntrl 23 1 pex0_en PCIe 0 Clock out 24 2 pex1_en PCIe 1 Clock out 25 3 ge1 Gigabit Ethernet 1 26 4 ge0 Gigabit Ethernet 0 27 5 pex0 PCIe Cntrl 0 28 9 pex1 PCIe Cntrl 1 29 15 sata0 SATA Host 0 30 17 sdio SDHCI Host 31 23 crypto CESA (crypto engine) 32 25 tdm Time Division Mplx 33 28 ddr DDR Cntrl 34 30 sata1 SATA Host 0 35 36 The following is a list of provided IDs for Armada 375: 37 38 ID Clock Peripheral 39 ----------------------------------- 40 2 mu Management Unit 41 3 pp Packet Processor 42 4 ptp PTP 43 5 pex0 PCIe 0 Clock out 44 6 pex1 PCIe 1 Clock out 45 8 audio Audio Cntrl 46 11 nd_clk Nand Flash Cntrl 47 14 sata0_link SATA 0 Link 48 15 sata0_core SATA 0 Core 49 16 usb3 USB3 Host 50 17 sdio SDHCI Host 51 18 usb USB Host 52 19 gop Gigabit Ethernet MAC 53 20 sata1_link SATA 1 Link 54 21 sata1_core SATA 1 Core 55 22 xor0 XOR DMA 0 56 23 xor1 XOR DMA 0 57 24 copro Coprocessor 58 25 tdm Time Division Mplx 59 28 crypto0_enc Cryptographic Unit Port 0 Encryption 60 29 crypto0_core Cryptographic Unit Port 0 Core 61 30 crypto1_enc Cryptographic Unit Port 1 Encryption 62 31 crypto1_core Cryptographic Unit Port 1 Core 63 64 The following is a list of provided IDs for Armada 380/385: 65 66 ID Clock Peripheral 67 ----------------------------------- 68 0 audio Audio 69 2 ge2 Gigabit Ethernet 2 70 3 ge1 Gigabit Ethernet 1 71 4 ge0 Gigabit Ethernet 0 72 5 pex1 PCIe 1 73 6 pex2 PCIe 2 74 7 pex3 PCIe 3 75 8 pex0 PCIe 0 76 9 usb3h0 USB3 Host 0 77 10 usb3h1 USB3 Host 1 78 11 usb3d USB3 Device 79 13 bm Buffer Management 80 14 crypto0z Cryptographic 0 Z 81 15 sata0 SATA 0 82 16 crypto1z Cryptographic 1 Z 83 17 sdio SDIO 84 18 usb2 USB 2 85 21 crypto1 Cryptographic 1 86 22 xor0 XOR 0 87 23 crypto0 Cryptographic 0 88 25 tdm Time Division Multiplexing 89 28 xor1 XOR 1 90 30 sata1 SATA 1 91 92 The following is a list of provided IDs for Armada 39x: 93 94 ID Clock Peripheral 95 ----------------------------------- 96 5 pex1 PCIe 1 97 6 pex2 PCIe 2 98 7 pex3 PCIe 3 99 8 pex0 PCIe 0 100 9 usb3h0 USB3 Host 0 101 10 usb3h1 USB3 Host 1 102 15 sata0 SATA 0 103 17 sdio SDIO 104 22 xor0 XOR 0 105 28 xor1 XOR 1 106 107 The following is a list of provided IDs for Armada XP: 108 109 ID Clock Peripheral 110 ----------------------------------- 111 0 audio Audio Cntrl 112 1 ge3 Gigabit Ethernet 3 113 2 ge2 Gigabit Ethernet 2 114 3 ge1 Gigabit Ethernet 1 115 4 ge0 Gigabit Ethernet 0 116 5 pex0 PCIe Cntrl 0 117 6 pex1 PCIe Cntrl 1 118 7 pex2 PCIe Cntrl 2 119 8 pex3 PCIe Cntrl 3 120 13 bp 121 14 sata0lnk 122 15 sata0 SATA Host 0 123 16 lcd LCD Cntrl 124 17 sdio SDHCI Host 125 18 usb0 USB Host 0 126 19 usb1 USB Host 1 127 20 usb2 USB Host 2 128 22 xor0 XOR DMA 0 129 23 crypto CESA engine 130 25 tdm Time Division Mplx 131 28 xor1 XOR DMA 1 132 29 sata1lnk 133 30 sata1 SATA Host 1 134 135 The following is a list of provided IDs for 98dx3236: 136 137 ID Clock Peripheral 138 ----------------------------------- 139 3 ge1 Gigabit Ethernet 1 140 4 ge0 Gigabit Ethernet 0 141 5 pex0 PCIe Cntrl 0 142 17 sdio SDHCI Host 143 18 usb0 USB Host 0 144 22 xor0 XOR DMA 0 145 146 The following is a list of provided IDs for Dove: 147 148 ID Clock Peripheral 149 ----------------------------------- 150 0 usb0 USB Host 0 151 1 usb1 USB Host 1 152 2 ge Gigabit Ethernet 153 3 sata SATA Host 154 4 pex0 PCIe Cntrl 0 155 5 pex1 PCIe Cntrl 1 156 8 sdio0 SDHCI Host 0 157 9 sdio1 SDHCI Host 1 158 10 nand NAND Cntrl 159 11 camera Camera Cntrl 160 12 i2s0 I2S Cntrl 0 161 13 i2s1 I2S Cntrl 1 162 15 crypto CESA engine 163 21 ac97 AC97 Cntrl 164 22 pdma Peripheral DMA 165 23 xor0 XOR DMA 0 166 24 xor1 XOR DMA 1 167 30 gephy Gigabit Ethernet PHY 168 Note: gephy(30) is implemented as a parent clock of ge(2) 169 170 The following is a list of provided IDs for Kirkwood: 171 172 ID Clock Peripheral 173 ----------------------------------- 174 0 ge0 Gigabit Ethernet 0 175 2 pex0 PCIe Cntrl 0 176 3 usb0 USB Host 0 177 4 sdio SDIO Cntrl 178 5 tsu Transp.
