Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

Device-Tree bindings for tilcdc DRM driver
|
|
|
|
Required properties:
|
|
- compatible: value should be one of the following:
|
|
- "ti,am33xx-tilcdc" for AM335x based boards
|
|
- "ti,da850-tilcdc" for DA850/AM18x/OMAP-L138 based boards
|
|
- interrupts: the interrupt number
|
|
- reg: base address and size of the LCDC device
|
|
|
|
Recommended properties:
|
|
- ti,hwmods: Name of the hwmod associated to the LCDC
|
|
|
|
Optional properties:
|
|
- max-bandwidth: The maximum pixels per second that the memory
|
|
interface / lcd controller combination can sustain
|
|
- max-width: The maximum horizontal pixel width supported by
|
|
the lcd controller.
|
|
- max-pixelclock: The maximum pixel clock that can be supported
|
|
by the lcd controller in KHz.
|
|
- blue-and-red-wiring: Recognized values "straight" or "crossed".
|
|
This property deals with the LCDC revision 2 (found on AM335x)
|
|
color errata [1].
|
|
- "straight" indicates normal wiring that supports RGB565,
|
|
BGR888, and XBGR8888 color formats.
|
|
- "crossed" indicates wiring that has blue and red wires
|
|
crossed. This setup supports BGR565, RGB888 and XRGB8888
|
|
formats.
|
|
- If the property is not present or its value is not recognized
|
|
the legacy mode is assumed. This configuration supports RGB565,
|
|
RGB888 and XRGB8888 formats. However, depending on wiring, the red
|
|
and blue colors are swapped in either 16 or 24-bit color modes.
|
|
|
|
Optional nodes:
|
|
|
|
- port/ports: to describe a connection to an external encoder. The
|
|
binding follows Documentation/devicetree/bindings/graph.txt and
|
|
supports a single port with a single endpoint.
|
|
|
|
- See also Documentation/devicetree/bindings/display/tilcdc/panel.txt and
|
|
Documentation/devicetree/bindings/display/bridge/ti,tfp410.txt for connecting
|
|
tfp410 DVI encoder or lcd panel to lcdc
|
|
|
|
[1] There is an errata about AM335x color wiring. For 16-bit color mode
|
|
the wires work as they should (LCD_DATA[0:4] is for Blue[3:7]),
|
|
but for 24 bit color modes the wiring of blue and red components is
|
|
crossed and LCD_DATA[0:4] is for Red[3:7] and LCD_DATA[11:15] is
|
|
for Blue[3-7]. For more details see section 3.1.1 in AM335x
