description: |
Expected external clocks, defined in DTS as fixed-rate clocks with a matching
name::
- "fin_pll" - PLL input clock from XXTI
- "xrtcxti" - input clock from XRTCXTI
- "ioclk_pcm_extclk" - pcm external operation clock
- "ioclk_spdif_extclk" - spdif external operation clock
- "ioclk_i2s_cdclk" - i2s0 codec clock
Phy clocks::
There are several clocks which are generated by specific PHYs. These clocks
are fed into the clock controller and then routed to the hardware blocks.
These clocks are defined as fixed clocks in the driver with following names::
- "phyclk_dptx_phy_ch3_txd_clk" - dp phy clock for channel 3
- "phyclk_dptx_phy_ch2_txd_clk" - dp phy clock for channel 2
- "phyclk_dptx_phy_ch1_txd_clk" - dp phy clock for channel 1
- "phyclk_dptx_phy_ch0_txd_clk" - dp phy clock for channel 0
- "phyclk_hdmi_phy_tmds_clko" - hdmi phy tmds clock
- "phyclk_hdmi_phy_pixel_clko" - hdmi phy pixel clock
- "phyclk_hdmi_link_o_tmds_clkhi" - hdmi phy for hdmi link
- "phyclk_dptx_phy_o_ref_clk_24m" - dp phy reference clock
- "phyclk_dptx_phy_clk_div2"
- "phyclk_mipi_dphy_4l_m_rxclkesc0"
- "phyclk_usbhost20_phy_phyclock" - usb 2.0 phy clock
- "phyclk_usbhost20_phy_freeclk"
- "phyclk_usbhost20_phy_clk48mohci"
- "phyclk_usbdrd30_udrd30_pipe_pclk"
- "phyclk_usbdrd30_udrd30_phyclock" - usb 3.0 phy clock
All available clocks are defined as preprocessor macros in
include/dt-bindings/clock/exynos5260-clk.h header.
