0016 Expected external clocks, defined in DTS as fixed-rate clocks with a matching
0017 name::
0018 - "fin_pll" - PLL input clock from XXTI
0019 - "xrtcxti" - input clock from XRTCXTI
0020 - "ioclk_pcm_extclk" - pcm external operation clock
0021 - "ioclk_spdif_extclk" - spdif external operation clock
0022 - "ioclk_i2s_cdclk" - i2s0 codec clock
0023
0024 Phy clocks::
0025 There are several clocks which are generated by specific PHYs. These clocks
0026 are fed into the clock controller and then routed to the hardware blocks.
0027 These clocks are defined as fixed clocks in the driver with following names::
0028 - "phyclk_dptx_phy_ch3_txd_clk" - dp phy clock for channel 3
0029 - "phyclk_dptx_phy_ch2_txd_clk" - dp phy clock for channel 2
0030 - "phyclk_dptx_phy_ch1_txd_clk" - dp phy clock for channel 1
0031 - "phyclk_dptx_phy_ch0_txd_clk" - dp phy clock for channel 0
0032 - "phyclk_hdmi_phy_tmds_clko" - hdmi phy tmds clock
0033 - "phyclk_hdmi_phy_pixel_clko" - hdmi phy pixel clock
0034 - "phyclk_hdmi_link_o_tmds_clkhi" - hdmi phy for hdmi link
0035 - "phyclk_dptx_phy_o_ref_clk_24m" - dp phy reference clock
0036 - "phyclk_dptx_phy_clk_div2"
0037 - "phyclk_mipi_dphy_4l_m_rxclkesc0"
0038 - "phyclk_usbhost20_phy_phyclock" - usb 2.0 phy clock
0039 - "phyclk_usbhost20_phy_freeclk"
0040 - "phyclk_usbhost20_phy_clk48mohci"
0041 - "phyclk_usbdrd30_udrd30_pipe_pclk"
0042 - "phyclk_usbdrd30_udrd30_phyclock" - usb 3.0 phy clock
0043
0044 All available clocks are defined as preprocessor macros in
0045 include/dt-bindings/clock/exynos5260-clk.h header.
