Subject: [PATCH 0/8] mmc: sdhci-esdhc-imx: add SD3.0 support
Date: Wed, 4 Sep 2013 20:54:09 +0800 [thread overview]
Message-ID: <1378299257-2980-1-git-send-email-b29396@freescale.com> (raw)
This patch series add SD3.0 support for i.MX6Q/DL.
Since freescale i.MX6Q/DL uSDHC clock tuning progress is a little different from
the standard tuning process defined in host controller spec v3.0.
So we add a hook to allow execute platform specific tuning instead of
standard host controller tuning.
The main difference are:
1) not only generate Buffer Read Ready interrupt when tuning is performing.
It generates all other DATA interrupts like the normal data command.
2) SDHCI_CTRL_EXEC_TUNING is not automatically cleared by HW,
instead it's controlled by SW.
3) SDHCI_CTRL_TUNED_CLK is not automatically set by HW,
it's controlled by SW.
4) the clock delay for every tuning is set by SW.
Tested on i.MX6Q Sabreauto board.
The series is based on latest Linus tree.
