[PATCH v2 0/6] TQMa91/TQMa93: display support on MBa91xxCA

[PATCH v2 0/6] TQMa91/TQMa93: display support on MBa91xxCA

[Alexander Stein]

Hi,

this series adds support for parallel and LVDS displays on MBa91xxCA, both for
TQMa91 and TQMa93. The parallel display is attached directly, while the LVDS
uses an LVDS-Encoder. To actually work it needs the pdfc driver from [1].

The first two patches add required (Video) PLL configurations to achieve the
necessary pixel clocks for both displays.
The last 4 patches add the overlays for TQMa91 and TQMa93, although the
overlays for TQMa91 use the same overlay for TQMa93.

Best regards,
Alexander

[PATCH v2 1/6] clk: imx: fracn-gppll: Add 333.333333 MHz support

[Alexander Stein]

Some parallel panels have a pixelclk of 33.30 MHz. Add support for
333.333333 MHz so a by 10 divider can be used to derive the exact pixelclk.

[PATCH v2 2/6] clk: imx: fracn-gppll: Add 477.4MHz support

[Alexander Stein]

Add the 477.4MHz frequency support that can be used for display with
pixelclk of 68.2 MHz. The divider of 7 is important for LVDS output on
imx93. It is also usable for parallel output.
