Exynos MIPI-DSIM Controller
|
|
=========================
|
|
|
|
Required properties:
|
|
SOC specific:
|
|
compatible: should be "samsung,exynos-mipi-dsi"
|
|
reg: Base address of MIPI-DSIM IP.
|
|
|
|
Board specific:
|
|
samsung,dsim-config-e-interface: interface to be used (RGB interface
|
|
for main display or CPU interface for main or sub display).
|
|
samsung,dsim-config-e-virtual-ch: virtual channel number that main
|
|
or sub display uses.
|
|
samsung,dsim-config-e-pixel-format: pixel stream format for main
|
|
or sub display.
|
|
samsung,dsim-config-e-burst-mode: selects Burst mode in Video mode.
|
|
in Non-burst mode, RGB data area is filled with RGB data and
|
|
NULL packets, according to input bandwidth of RGB interface.
|
|
samsung,dsim-config-e-no-data-lane: data lane count used by Master.
|
|
samsung,dsim-config-e-byte-clk: select byte clock source.
|
|
It must be DSIM_PLL_OUT_DIV8.
|
|
DSIM_EXT_CLK_DIV8 and DSIM_EXT_CLK_BYPASSS are not supported.
|
|
samsung,dsim-config-hfp: HFP disable mode.
|
|
If set, DSI master ignores HFP area in VIDEO mode.
|
|
In command mode, this variable is ignored.
|
|
samsung,dsim-config-p: P value for PMS setting.
|
|
samsung,dsim-config-m: M value for PMS setting.
|
|
samsung,dsim-config-s: S value for PMS setting.
|
|
samsung,dsim-config-pll-stable-time: the PLL Timer for stability
|
|
of the ganerated clock.
|
|
samsung,dsim-config-esc-clk: escape clock frequency for getting
|
|
the escape clock prescaler value.
|
|
samsung,dsim-config-stop-holding-cnt: the interval value between
|
|
transmitting read packet (or write "set_tear_on" command)
|
|
and BTA request. After transmitting read packet or write
|
|
"set_tear_on" command, BTA requests to D-PHY automatically.
|
|
This counter value specifies the interval between them.
|
|
samsung,dsim-config-bta-timeout: the timer for BTA. This register
|
|
specifies time out from BTA request to change the direction
|
|
with respect to Tx escape clock.
|
|
samsung,dsim-config-rx-timeout: the timer for LP Rx mode timeout.
|
|
this register specifies time out on how long RxValid deasserts,
|
|
after RxLpdt asserts with respect to Tx escape clock.
|
|
- RxValid specifies Rx data valid indicator.
|
|
- RxLpdt specifies an indicator that D-PHY is under RxLpdt mode
|
|
- RxValid and RxLpdt specifies signal from D-PHY.
|
|
samsung,dsim-device-name: name of the device.
|
|
samsung,dsim-device-id: unique device id.
|
|
samsung,dsim-device-bus_id: bus id for identifing connected bus
|
|
and this bus id should be same as id of mipi_dsim_device.
|
|
|
|
Optional properties:
|
|
samsung,dsim-device-reverse-panel: reverse panel.
|
|
|
|
