With LCD and keypad support SC6531E barebox port will be a nice demo for barebox presentation and can be added to mainline repo. There are some ready-to-use SC6531E drivers in the https://github.com/strongtz/linux-sprd repo. LCD display is connected via SPI so drivers/spi/spi-sprd.c can be used, also we need backlight driver. Keypad is supported by drivers/input/keyboard/sprd_keypad.c. > Sascha > > On Sat, Jun 10, 2023 at 01:32:16PM +0300, Antony Pavlov wrote: > > This patch series adds initial support for SC6531E chip. > > > > SC6431E chip is specially designed solution for creating > > feature phones.

Re: [RFC 0/4] Run barebox on sc6531e-based feature phone
Hi Antony, This has stayed unanswered for some time. I am not sure what I should do with it. In the current form I think it's a bit too basic to be useful. Maybe we can add it once the LCD and Keypad driver is ready?

[RFC 0/4] Run barebox on sc6531e-based feature phone
This patch series adds initial support for SC6531E chip. SC6431E chip is specially designed solution for creating feature phones. It contains * ARM926EJ-S core (up to 208 MHz) * embedded PSRAM * peripherals: USB, SPI, UART, IIS, PCM, I2C, keypad, LCD * SIM card and GSM/GPRS/FM/BT stuff This work is based on FPDoom, see [1], [2], [3] for details. At the moment only timer and debug_ll output via USB are supported. After adding lcd and keypad driver running bareDOOM [4] on SC6531E will be possible.
