Ok, so LCD7 is working now.
What I did:
in pinmux file:
bbcape_lcd7_pins: bbcape_lcd7_pins {
pinctrl-single,pins = <
*0x150 (PIN_OUTPUT_PULLUP | MUX_MODE7) /* spi0_sclk.gpio0_2, OUTPUT | MODE7
- AVDD_EN */*
0xa0 (PIN_OUTPUT | MUX_MODE0) /* lcd_data0.lcd_data0 */
*0xa3 (PIN_OUTPUT | MUX_MODE0) /* lcd_data1.lcd_data1 */*
0xa8 (PIN_OUTPUT | MUX_MODE0) /* lcd_data2.lcd_data2 */
0xac (PIN_OUTPUT | MUX_MODE0) /* lcd_data3.lcd_data3 */
0xb0 (PIN_OUTPUT | MUX_MODE0) /* lcd_data4.lcd_data4 */
0xb4 (PIN_OUTPUT | MUX_MODE0) /* lcd_data5.lcd_data5 */
0xb8 (PIN_OUTPUT | MUX_MODE0) /* lcd_data6.lcd_data6 */
0xbc (PIN_OUTPUT | MUX_MODE0) /* lcd_data7.lcd_data7 */
0xc0 (PIN_OUTPUT | MUX_MODE0) /* lcd_data8.lcd_data8 */
0xc4 (PIN_OUTPUT | MUX_MODE0) /* lcd_data9.lcd_data9 */
0xc8 (PIN_OUTPUT | MUX_MODE0) /* lcd_data10.lcd_data10 */
0xcc (PIN_OUTPUT | MUX_MODE0) /* lcd_data11.lcd_data11 */
0xd0 (PIN_OUTPUT | MUX_MODE0) /* lcd_data12.lcd_data12 */
0xd4 (PIN_OUTPUT | MUX_MODE0) /* lcd_data13.lcd_data13 */
0xd8 (PIN_OUTPUT | MUX_MODE0) /* lcd_data14.lcd_data14 */
0xdc (PIN_OUTPUT | MUX_MODE0) /* lcd_data15.lcd_data15 */
0xe0 (PIN_OUTPUT | MUX_MODE0) /* lcd_vsync.lcd_vsync */
0xe4 (PIN_OUTPUT | MUX_MODE0) /* lcd_hsync.lcd_hsync */
0xe8 (PIN_OUTPUT | MUX_MODE0) /* lcd_pclk.lcd_pclk */
0xec (PIN_OUTPUT | MUX_MODE0) /* lcd_ac_bias_en.lcd_ac_bias_en (lcd_en) */

};
in bone-panel-800x480
panel {
status = "okay";
compatible = "ti,tilcdc,panel";
pinctrl-names = "default";
pinctrl-0 = <*&bbcape_lcd7_pins*>;
panel-info {
ac-bias = <255>;
ac-bias-intrpt = <0>;
dma-burst-sz = <16>;
bpp = <16>;
fdd = <0x80>;
sync-edge = <0>;
sync-ctrl = <1>;
raster-order = <0>;
fifo-th = <0>;
* tft-alt-mode = <0>;*
* stn-565-mode = <0>;*
};
display-timings {
native-mode = <&timing0>;
/* Settings for ThreeFive S9700RTWV35TR / LCD7 cape: */
timing0: 800x480 {
clock-frequency = <30000000>;
hactive = <800>;
vactive = <480>;
hfront-porch = <40>;
hback-porch = <40>;
hsync-len = <48>;
vback-porch = <29>;
vfront-porch = <13>;
vsync-len = <3>;
hsync-active = <0>;
vsync-active = <0>;
};
};
};
Looks like the lcd.data1 which is used on 7" screens is not the same as on
4" ones.
As for Pruss, in 3.15 bone 6 I patched uio_pruss.c driver, and enabled it
in dts / Kernel config.
Will check for your remoteproc driver.
Thanks
