16 Expected external clocks, defined in DTS as fixed-rate clocks with a matching
17 name::
18 - "fin_pll" - PLL input clock from XXTI
19 - "xrtcxti" - input clock from XRTCXTI
20 - "ioclk_pcm_extclk" - pcm external operation clock
21 - "ioclk_spdif_extclk" - spdif external operation clock
22 - "ioclk_i2s_cdclk" - i2s0 codec clock
23
24 Phy clocks::
25 There are several clocks which are generated by specific PHYs. These clocks
26 are fed into the clock controller and then routed to the hardware blocks.
27 These clocks are defined as fixed clocks in the driver with following names::
28 - "phyclk_dptx_phy_ch3_txd_clk" - dp phy clock for channel 3
29 - "phyclk_dptx_phy_ch2_txd_clk" - dp phy clock for channel 2
30 - "phyclk_dptx_phy_ch1_txd_clk" - dp phy clock for channel 1
31 - "phyclk_dptx_phy_ch0_txd_clk" - dp phy clock for channel 0
32 - "phyclk_hdmi_phy_tmds_clko" - hdmi phy tmds clock
33 - "phyclk_hdmi_phy_pixel_clko" - hdmi phy pixel clock
34 - "phyclk_hdmi_link_o_tmds_clkhi" - hdmi phy for hdmi link
35 - "phyclk_dptx_phy_o_ref_clk_24m" - dp phy reference clock
36 - "phyclk_dptx_phy_clk_div2"
37 - "phyclk_mipi_dphy_4l_m_rxclkesc0"
38 - "phyclk_usbhost20_phy_phyclock" - usb 2.0 phy clock
39 - "phyclk_usbhost20_phy_freeclk"
40 - "phyclk_usbhost20_phy_clk48mohci"
41 - "phyclk_usbdrd30_udrd30_pipe_pclk"
42 - "phyclk_usbdrd30_udrd30_phyclock" - usb 3.0 phy clock
43
44 All available clocks are defined as preprocessor macros in
45 include/dt-bindings/clock/exynos5260-clk.h header.
