Subject: [PATCH v1 0/2] Add StarFive JHB100 DWCMSHC controller support
Date: Sat, 19 Sep 2026 02:29:48 -0700 [thread overview]
Message-ID: <20260919092950.178617-1-changhuang.liang@starfivetech.com> (raw)
Add DWCMSHC controller driver for StarFive JHB100 SoC.
This series has been tested on the JHB100 EVB1 board.
Due to syscon limitations, it is necessary to use dma-ranges
to restrict the DMA address space of the eMMC controller to:
[0x400000000 - 0x4ffffffff]
bus_nioc_4g: bus_nioc_4g {
compatible = "simple-bus";
#address-cells = <2>;
#size-cells = <2>;
dma-noncoherent;
ranges;
dma-ranges = <0x4 0x00000000 0x0 0x40000000 0x1 0x0>,
<0x4 0x00000000 0x4 0x00000000 0x1 0x0>;
emmc0: mmc@11b00000 {
compatible = "starfive,jhb100-dwcmshc";
reg = <0x0 0x11b00000 0x0 0x10000>;
};
};
