Subject: [PATCH 44/82] ARM: dts: sun8i-a83t-tbs-a711: Add PN544 NFC support
|
|
|
|
Regulators on the schematic are named incorrectly. Both cameras are
|
|
is in fact connected to the dvdd-csi-f regulator and dvdd-csi-r is
|
|
in reality used for digital pad supply for NFC chip.
|
|
|
|
At the same time vcc-mipi regulator is not used for MIPI, but for NFC
|
|
VBAT power.
|
|
|
|
Interpreting schematics is an art form! :D
