However these bits are still connected -internally meaning the mmc block recieves signals on all data lines -and seems the internal HW CRC checks get corrupted by this erroneous -data. - -We cannot control what data is sent on these lines because they go -to external ports. 1 bit mode does not exhibit the issue hence the -safe default is to use this. If a user knows that in their use case -they will not use the upper bits then they can set to 4 bit mode in -order to improve performance. - -Also make sure that the upper 4 bits don't get allocated to the mmc -driver (the default is to assign all 8 pins) so they can be allocated -to other drivers. Allocating all 4 despite setting 1 bit mode as this -matches what is there in hardware. - -Signed-off-by: Ian Pozella ---- - arch/mips/boot/dts/img/pistachio_marduk.dts | 3 ++- - 1 file changed, 2 insertions(+), 1 deletion(-) - ---- a/arch/mips/boot/dts/img/pistachio_marduk.dts -+++ b/arch/mips/boot/dts/img/pistachio_marduk.dts -@@ -120,7 +120,7 @@ - - &sdhost { - status = "okay"; -- bus-width = <4>; -+ bus-width = <1>; - disable-wp; - }; - -@@ -130,6 +130,7 @@ - - &pin_sdhost_data { - drive-strength = <2>; -+ pins = "mfio17", "mfio18", "mfio19", "mfio20"; - }; - - &pwm { -- cgit v1.2.3
