[PATCH v2 34/34] ARM: tegra: apalis_t30: support v1.1 hardware revision

From: Marcel Ziswiler
Date: Fri Aug 31 2018 - 12:39:46 EST

From: Marcel Ziswiler <marcel.ziswiler@xxxxxxxxxxx>

Support the V1.1 hardware revisions with the following change:

Changed power rail for MMC1 interface to a 3.3V/1.8V switchable rail in
order to be able to run UHS SD cards in ultra high speed 1.8V mode.

[ 207.502011] mmc2: host does not support reading read-only switch,
assuming write-enable
[ 207.517011] mmc2: new ultra high speed SDR104 SDHC card at address
aaaa
[ 207.534190] mmcblk2: mmc2:aaaa SE32G 29.7 GiB
[ 207.545096] mmcblk2: p1

root@apalis-t30:~# cat /sys/kernel/debug/mmc2/ios
clock: 208000000 Hz
actual clock: 204000000 Hz
vdd: 21 (3.3 ~ 3.4 V)
bus mode: 2 (push-pull)
chip select: 0 (don't care)
power mode: 2 (on)
bus width: 2 (4 bits)
timing spec: 6 (sd uhs SDR104)
signal voltage: 1 (1.80 V)
driver type: 0 (driver type B)
root@apalis-t30:~# hdparm -t /dev/mmcblk2

/dev/mmcblk2:
Timing buffered disk reads: 256 MB in 3.02 seconds = 84.71 MB/sec

Changes in v2:
- Updated V1.1 device trees with all applicable previous fixes.
