AM3358: Is support available for DS90CF383BMTX (LCD) and TPS65910A31A1RSLR (PMIC) in kernel 6.1

Prafull Barpute

Part Number: AM3358

Tool/software:

We are upgrading kernel from 3.2 version to 6.1 version. Board has some old components like DS90CF383BMTX for LCD display and TPS65910A31A1RSLR as PMIC.

While configuring dts file for new kernel 6.1 version, we found that there is no supporting driver for these devices. So we cannot bring-up LCD display.

am33xx.dsti ( from kernel 3.1 )

It is removed in am33xx.dtsi from kernel 6.1

So, Is there any generic driver support added which support DS90CF383BMTX device or do we need to move old driver to this new kernel.

Exactly same query for another component (PMIC) TPS65910A31A1RSLR present on our custom board.

Thanks.

Hello,

We will keep this thread to discuss the LCD support. Please make a seperate thread for the PMIC discussion. This thread will be re-assigned to the display expert.

Thanks,

Anshu

Hi,

I was doing quick search under Kernel/drivers and I don't see anything for DS90CF383BMTX and there is a possibility you need to migrate the driver. Also, the lcdc is the display driver for AM335x and the display driver will communicate with the bridge driver.
