* ENGR00142995 MX50: Enable uSDHC instead of eSDHC for SDR modeAnish Trivedi2011-05-10-1/+3
| | | | | | | | | | | | | | | | | | On SD3 on MX50, there is an option to choose eSDHC or uSDHC controller. By default eSDHC is selected. However, eSDHC shows some borderline timing in SDR mode at 50 MHz, whereas uSDHC shows borderline timing in DDR mode at 50 MHz. Therefore, add a compile time option to uboot for MX50 to select uSDHC in SDR mode or eSDHC in DDR mode on SD3 port. By default the compile time option, CONFIG_MX50_ENABLE_USDHC_SDR, is commented out in the include/configs/mx50_<board>.h file to select eSDHC with DDR mode enabled. Uncomment the define to select uSDHC with only SDR mode enabled. Also increased max frequency supported by ESDHC to 52 MHz instead of 50 MHz. Signed-off-by: Anish Trivedi <anish@freescale.com>
* ENGR00133579 Uboot ESDHCv3 Remove workaround for DLLAnish Trivedi2010-12-01-0/+4
| | | | | | | | | | On MX50 TO 1.0, DLL did not work in slave mode, so slave override mode was used instead. Removed this workaround, except for TO 1.0. Starting with TO 1.1, the DLL in slave mode is working as expected. Signed-off-by: Anish Trivedi <anish@freescale.com> Signed-off-by: Terry Lv <r65388@freescale.com>

* fsl_esdhc: Add device tree fixupsAnton Vorontsov2009-07-16-0/+8
| | | | | | | | | | | This patch implements fdt_fixup_esdhc() function that is used to fixup the device tree. The function adds status = "disabled" propery if esdhc pins muxed away, otherwise it fixups clock-frequency for esdhc nodes.
