-* Samsung Exynos5260 Clock Controller
-
-Exynos5260 has 13 clock controllers which are instantiated
-independently from the device-tree. These clock controllers
-generate and supply clocks to various hardware blocks within
-the SoC.
-
-Each clock is assigned an identifier and client nodes can use
-this identifier to specify the clock which they consume. All
-available clocks are defined as preprocessor macros in
-dt-bindings/clock/exynos5260-clk.h header and can be used in
-device tree sources.
-
-External clocks:
-
-There are several clocks that are generated outside the SoC. It
-is expected that they are defined using standard clock bindings
-with following clock-output-names:
-
- - "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
-
