Subject: [PATCH v4 0/2] drm/panel: Add support for the FocusLCDs E35GH-I-MW800CB
Date: Tue, 26 May 2026 23:22:58 -0700 [thread overview]
Message-ID: <20260527062300.88928-1-igor@reznichenko.net> (raw)
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.
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
