Some spi panel initial sequence include several cmd arrays and delay is needed between arrays. So an ops is more proper for LCD driver to hook, instead of feeding commands. Standard SPI bus implementation is decent than current implementation. > + > +static struct mmp_mode mmp_modes_tpohvga[] = { > + [0] = { > + .pixclock_freq = 10394400, > + .refresh = 60, > + .xres = 320, > + .yres = 480, > + .hsync_len = 10, > + .left_margin = 15, > + .right_margin = 10, > + .vsync_len = 2, > + .upper_margin = 4, > + .lower_margin = 2, > + .invert_pixclock = 1, > + .pix_fmt_out = PIXFMT_RGB565, > + }, > +}; > + > +static int tpohvga_get_modelist(struct mmp_panel *panel, > + struct mmp_mode **modelist) > +{ > + *modelist = mmp_modes_tpohvga; > + return 1; > +} > + > +static struct mmp_panel panel_tpohvga = { > + .name = "tpohvga", > + .panel_type = PANELTYPE_Active, > + .get_modelist = tpohvga_get_modelist, > + .cmd_set = &tpohvga_spi_cmds, > +}; > + > +static int __devinit tpohvga_probe(struct platform_device *pdev) > +{ > + struct mmp_mach_panel_info *mi; > + /* get configs from platform data */ > + mi = pdev->dev.platform_data; > + if (mi == NULL) { > + dev_err(&pdev->dev, "%s: no platform data defined\n", __func__); > + return -EINVAL; > + } > + > + panel_tpohvga.plat_set_onoff = mi->plat_set_onoff; > + panel_tpohvga.plat_path_name = mi->plat_path_name; > + panel_tpohvga.dev = &pdev->dev; > + > + if (!mmp_register_panel(&panel_tpohvga)) { > + dev_err(&pdev->dev, "%s: register failed\n", __func__); > + return -EINVAL; > + } > + return 0; > +} > + > +static struct platform_driver panel_tpohvga_driver = { > + .driver = { > + .name = "tpo-hvga", > + .owner = THIS_MODULE, > + }, > + .probe = tpohvga_probe, > +}; > + > +static int __devinit panel_tpohvga_init(void) > +{ > + return platform_driver_register(&panel_tpohvga_driver); > +} > +module_init(panel_tpohvga_init); > + > +MODULE_AUTHOR("Lisa Du<cldu@xxxxxxxxxxx>"); > +MODULE_DESCRIPTION("Panel driver for tpohvga"); > +MODULE_LICENSE("GPL"); > -- > 1.7.0.4 > > -- > To unsubscribe from this list: send the line "unsubscribe linux-fbdev" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-fbdev" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
