Faiz Abbas fb59ee37cf ARM: dts: am57xx: Disable voltage switching for SD card ... If UHS speed modes are enabled, a compatible SD card switches down to 1.8V during enumeration. If after this a software reboot/crash takes place and on-chip ROM tries to enumerate the SD card, the difference in IO voltages (host @ 3.3V and card @ 1.8V) may end up damaging the card. The fix for this is to have support for power cycling the card in hardware (with a PORz/soft-reset line causing a power cycle of the card). Because the beaglebone X15 (rev A,B and C), am57xx-idks and am57xx-evms don't have this capability, disable voltage switching for these boards. The major effect of this is that the maximum supported speed mode is now high speed(50 MHz) down from SDR104(200 MHz). commit 88a748419b ("ARM: dts: am57xx-idk: Remove support for voltage switching for SD card") did this only for idk boards. Do it for all affected boards. Signed-off-by: Faiz Abbas <faiz_abbas@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>		2019-06-27 04:38:32 -07:00
