In order to support burst mode, vendor drivers set lane_mbps higher than bandwidth through DPI interface. So, calculate horizontal component lane byte clock cycle(lbcc) based on lane_mbps instead of pixel clock rate for burst mode. Fixes: ac87d236 ("drm/bridge: synopsys: dw-mipi-dsi: Use pixel clock rate to calculate lbcc") Reported-by:

Currently drm_client_buffer_addfb() uses the legacy drm_mode_addfb(), which uses bpp and depth to guess the wanted buffer format. However, drm_client_buffer_addfb() already knows the exact buffer format, so there is no need to convert back and forth between buffer format and bpp/depth, and the function can just call drm_mode_addfb2() directly instead.

DRM_PANEL_ILITEK_ILI9882T is being split out from DRM_PANEL_BOE_TV101WUM_NL6. Since the arm64 defconfig had the BOE panel driver enabled, let's also enable the Ilitek driver. Reviewed-by:

At present, we have found that there may be a problem of blurred screen during fast sleep/resume. The direct cause of the blurred screen is that the IC does not receive 0x28/0x10. Because of the particularity of the IC, before the panel enters sleep hid must stop scanning, as i2c_hid_core_suspend before ili9882t_disable. If move the ili9882t_enter_sleep_mode function to ili9882t_unprepare, touch reset will pull low before panel entersleep, which does not meet the timing requirements.. So in order to solve this problem, the IC can handle it through the exception mechanism when it cannot receive 0x28/0x10 command. Handling exceptions requires a reset 50ms delay. Refer to vendor detailed analysis [1]. Ilitek vendor also suggested switching the page before entering sleep to avoid panel IC not receiving 0x28/0x10 command. Note: 0x28 is display off, 0x10 is sleep in. [1]: https://github.com/ILITEK-LoganLin/Document/tree/main/ILITEK_Power_SequenceSigned-off-by:

The Starry ILI9882t-based panel should never have been part of the boe tv101wum driver, it is clearly based on the Ilitek ILI9882t display controller and if you look at the custom command sequences for the panel these clearly contain the signature Ilitek page switch (0xff) commands. The hardware has nothing in common with the other panels supported by this driver. Break this out into a separate driver and config symbol instead. If the placement here is out of convenience for using similar code, we should consider creating a helper library instead. Co-developed-by:

Initialize the instance of struct fb_ops with fbdev initializer macros for framebuffers in I/O address space. Set the read/write, draw and mmap callbacks to the correct implementation and avoid implicit defaults. Also select the necessary I/O helpers in Kconfig. Fbdev drivers sometimes rely on the callbacks being NULL for a default implementation to be invoked; hence requiring the I/O helpers to be built in any case. Setting all callbacks in all drivers explicitly will allow to make the I/O helpers optional. This benefits systems that do not use these functions. No functional changes. Signed-off-by:
