Linus Torvalds 706eacadd5 Devicetree updates for v6.1: 
DT core:
 
 - Fix node refcounting in of_find_last_cache_level()
 
 - Constify device_node in of_device_compatible_match()
 
 - Fix 'dma-ranges' handling in bus controller nodes
 
 - Fix handling of initrd start > end
 
 - Improve error reporting in of_irq_init()
 
 - Taint kernel on DT unittest running
 
 - Use strscpy instead of strlcpy
 
 - Add a build target, dt_compatible_check, to check for
   compatible strings used in kernel sources against compatible strings
   in DT schemas.
 
 - Handle DT_SCHEMA_FILES changes when rebuilding
 
 DT bindings:
 
 - LED bindings for MT6370 PMIC
 
 - Convert Mediatek mtk-gce mailbox, MIPS CPU interrupt controller,
   mt7621 I2C, virtio,pci-iommu, nxp,tda998x, QCom fastrpc, qcom,pdc,
   and arm,versatile-sysreg to DT schema format
 
 - Add nvmem cells to u-boot,env schema
 
 - Add more LED_COLOR_ID definitions
 
 - Require 'opp-table' uses to be a node
 
 - Various schema fixes to match QEMU 'virt' DT usage
 
 - Tree wide dropping of redundant 'Device Tree Binding' in schema titles
 
 - More (unevaluated|additional)Properties fixes in schema child nodes
 
 - Drop various redundant minItems equal to maxItems

TCON can have 1 or 2 channels, usually with the

(RGB, LVDS, etc.), and the second being used for the
outputs that require another controller (TV Encoder,

If that property is present, specifies the TCON
channel the endpoint is associated to. If that
property is not present, the endpoint number will be
used as the channel number.
