Subject: [PATCH 1/3] ARM: dts: imx: ventana: set GW54xx PMIC swbst regulator
|
||||
as always-on
|
||||
|
||||
The GW54xx PMIC swbst regulator is used for LVDS power, CANbus xceiver
|
||||
and HDMI DDC and is enabled by the bootloader. Set the regulator to
|
||||
always-on so that Linux doesn't turn it off thinking its not needed.

Subject: [PATCH 3/3] ARM: dts: imx: ventana: Allow HDMI and LVDS to work
|
||||
simultaneously
|
||||
|
||||
Currently it is not possible to have HDMI and LVDS working simultaneously,
|
||||
because both ports try to use PLL5.
|
||||
|
||||
Move the LVDS clock parent to PLL3_USB_OTG, so that HDMI and LVDS can be
|
||||
driven from independent sources.
|
||||
|
||||
With this change the LDB pixel clock goes to 68.57 MHz, which is still
|
||||
within the valid range for the displays supported by the Ventana boards.
