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. |
||||
|
||||
Example: |
||||
mipidsi@11c80000 { |
||||
compatible = "samsung,exynos-mipi-dsi"; |
