| 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. |
