If panel has too small hfp or hbp, horizontal_frontporch_byte or
horizontal_backporch_byte may become very small value or negative
value. This patch adjusts their values so that they are greater
than minimum value and keep total of them unchanged.

nges since v2:
- update dt-bindings document for mt8183 dpi.
- separate dual edge modfication as independent patch.
Jitao Shi (1):
dt-bindings: display: mediatek: convert the dpi bindings to yaml

Convert display/mediatek/mediatek,dpi.txt to display/mediatek/mediatek,dpi.yaml
and remove the old text bindings.

DSI panel driver need attach function which is inculde in
mipi_dsi_host_ops.
If mipi_dsi_host_register is not in probe, dsi panel will
probe fail or more delay.
So move the mipi_dsi_host_register to probe from bind.

MT8183 dsi has two changes with mt8173.
1. Add the register double buffer control, but we no need it, So make
it default off.
2. Add picture size control.

Use the mtk_pwm_data struction to define different registers
and add MT8183 specific register operations, such as MT8183
have commit register, needs to enable double buffer
before writing register, and needs to select commit mode
and use PWM_PERIOD/PWM_HIGH_WIDTH.

MT8183 samples on rising and falling edge. It can reduce half data
io.
MT8173 also has those registers. But the hw function is removed.
So MT8173 doesn't support DPI dual edge sample and can't use the
same setting to mt8183.

MT8183 has different setting to MT8173(exist chip). We add mt8183 mipi_tx
driver.
1) Separate mipi_tx to common part and chip relate part.
2) Add mt8183 mipi_tx driver
Changes since v0:
- Separate two independent patches.
