Subject: [RFC PATCH v1 0/1] Add TH1520 eMMC/SD controller support
Date: Sat, 30 Mar 2024 20:59:45 +0300	[thread overview]
Message-ID: <20240330175948.80931-1-bigunclemax@gmail.com> (raw)

Hi list,

I want to introduce support for DesignWare SDHCI host controller
on Alibaba TH1520 SoC. The driver based on mainline Linux and Revyos
U-boot drivers. Work with eMMC and SD was tested on a LicheePi 4A board.

I would like to point out that the TH1520's SDHCI controller is very
similar to Rockchip's IPs those already have U-boot driver -
rockchip_sdhci.c
Also on Linux, T-head and Rockchip SDHCI controllers use a common driver -
sdhci-of-dwcmshc.c

At my glance we have two options:
 - leave TH1520 in a separate driver
 - stretch this driver on rockchip_sdhc

I chose the first option for now. And would be glad to hear your thoughts.

Best regards,
Maksim
