For the existing PHYs for new binding we are going to drop ref_clk_src clock and always use ref clock. Rather than introducing additional code to handle legacy vs current bindings (and clock names), use devm_clk_bulk_get_optional() when new bindings are used and devm_clk_bulk_get_all() when legacy bindings are in place.

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes. Signed-off-by:

This adds a bunch of new pixel clock- and tmds rates to the pre-pll table which are required to get more VESA and some DMT rates working. It has been completely re-calculated to match the min- and max-vco of (750 MHz - 3.2 GHz) requirements. If more than one configuration would have been possible the lowest fbdiv and refdiv (and therefore lowest vco rate) has been preferred. It's important to note, that RK3228 version of the phy does not support fractional dividers. To support the most possible rates for this version also in both 8-bit and 10-bit variant, some rates are not exact. The maximum deviation of the pixel clock is 0.26, which perfectly fits into VESA DMT recommendation of 0.5%. I tested all possible rates on several screens from different manufacturers with both RK3228 and RK3328. Both pre- and post-PLL locking are slighlty faster now. Signed-off-by:

Regular 8-bit and Deep Color video formats mainly differ in TMDS rate and not in pixel clock rate. When the hdmiphy clock is configured with the same pixel clock rate using clk_set_rate() the clock framework do not signal the hdmi phy driver to set_rate when switching between 8-bit and Deep Color. This result in pre/post pll not being re-configured when switching between regular 8-bit and Deep Color video formats. Fix this by calling set_rate in power_on to force pre pll re-configuration.

inno_hdmi_phy_rk3328_clk_recalc_rate() is returning a rate not found in the pre pll config table when the fractal divider is used. This can prevent proper power_on because a tmdsclock for the new rate is not found in the pre pll config table. Fix this by saving and returning a rounded pixel rate that exist in the pre pll config table. Fixes: 53706a11 ("phy: add Rockchip Innosilicon hdmi phy") Signed-off-by:

It seems the commit a2e927b0 ("phy: qcom-qmp-combo: Add sc8280xp USB/DP combo phys") contained a typo for selecting bias0_en values. First, bias0_en and bias1_en are expected to be symmetrical, and then the vendor driver also uses `flipped : 0x3E : 0x15` statement for bias0_en. Correct bias0_en programming to follow this.

Enabling clock for all the lanes consumes power even PHY is active or inactive. To resolve this, enable/disable clocks in phy_init/phy_exit. By default clock is disabled for all the lanes. Whenever phy_init called from USB, SATA, or display driver, etc. It enabled the required clock for requested lane. On phy_exit cycle, it disabled clock for the active PHYs. During the suspend/resume cycle, each USB/ SATA/ display driver called phy_exit/phy_init individually. It disabled clock on exit, and enabled on initialization for the active PHYs. Signed-off-by:
