Subject: [PATCH V2 0/5] mmc: add stm32 sdmmc controller
Date: Wed, 28 Feb 2018 16:47:19 +0100 [thread overview]
Message-ID: <1519832844-28068-1-git-send-email-ludovic.Barre@st.com> (raw)
From: Ludovic Barre <ludovic.barre@st.com>
This patch serie adds support of stm32 SDMMC controller.
stm32h7 is the first SoC to use stm32 SDMMC controller
(previous SoC had pl180 controller).
The SDMMC features include the following:
-Full compliance with MultiMediaCard System Specification Version 4.51.
Card support for three different databus modes:
1-bit (default), 4-bit and 8-bit.
-Full compliance with SD memory card specifications version 4.1.
SDR104 speed limited to maximum allowed I/O speed, SPI mode and
UHS-II mode not supported.
-Full compliance with SDIO card specification version 4.0.
change V2:
-dt-bindings: properties name
st,dir-output-high; st,neg-edge; st,use-ckin
-dt-bindings: node example s/sdmmc@/mmc@/g
-removes return of enable/disable_imask functions
-adds dev_warn if clk divisor is too short.
-replaces overprotection of n_elem by fail of dma_map_sg
-removes shortcut host->base
-Use device_property_present
