[PATCH v5 0/2] drm/panel: Add support for the FocusLCDs E35GH-I-MW800CB

From: Igor Reznichenko

Date: Fri May 29 2026 - 02:32:07 EST


Add support for E35GH-I-MW800CB 320x480 MIPI DSI panel by FocusLCDs.
The panel uses Ilitek ILI9488 driver IC in DSI mode specifically.
ILI9488 also appears in DBI/SPI panels, but those require different bus drivers.

This is a resend of v3. Since v3, this panel driver has been tested on
STM32MP157D-DK1 in addition to TI AM62P EVK. The panel works in video mode on
both platforms. Additional panels using ILI9488 DSI can be added later
with their own timings.

v5: Switched to devm_drm_panel_add() and devm_mipi_dsi_attach()
Dropped not required anymore .remove callback
Added display_info.bpc=6 initialization
Changed 0x21 DCS command to send 0 arguments as per spec

v4: Rebased
Tested 7.1-rc5 on STM32MP157D-DK1
Adjusted E35GH-I-MW800CB mode timing to a 14.4 MHz pixel clock with
slightly increased blanking to make it more synthesizable across DSI hosts

v3: Fixed missing Reviewed-by tag

v2: Added comment explaining the "focuslcds" vendor prefix
