   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.
