"Bindings:
- Convert smsc,lan91c111, qcom,spi-qup, qcom,msm-uartdm,
qcom,i2c-qup, qcom,gsbi, i2c-mt65xx, TI wkup_m3_ipc (and new
props), qcom,smp2p, TI timer, Mediatek gnss, Mediatek topckgen,
Mediatek apmixedsys, Mediatek infracfg, fsl,ls-extirq,
fsl,layerscape-dcfg, QCom PMIC SPMI, rda,8810pl-timer, Xilinx
zynqmp_ipi, uniphier-pcie, and Ilitek touchscreen controllers
- Convert various Arm Ltd peripheral IP bindings to schemas
- New bindings for Menlo board CPLD, DH electronics board CPLD,
Qualcomm Geni based QUP I2C, Renesas RZ/G2UL OSTM, Broafcom BCM4751
GNSS, MT6360 PMIC, ASIX USB Ethernet controllers, and
Microchip/SMSC LAN95xx USB Ethernet controllers
- Add vendor prefix for Enclustra
- Add various compatible string additions
- Various example fixes and cleanups
- Remove unused hisilicon,hi6220-reset binding
- Treewide fix properties missing type definition
- Drop some empty and unreferenced .txt bindings
- Documentation improvements for writing schemas
DT driver core:
- Drop static IRQ resources for DT platform devices as IRQ setup is
dynamic and drivers have all been converted to use
platform_get_irq() and friends
- Rework memory allocations and frees for overlays
- Continue overlay notifier callbacks on successful calls and add
unittests
- Handle 'interrupts-extended' in early DT IRQ setup
- Fix of_property_read_string() errors to match documentation
- Ignore disabled nodes in FDT API calls"

The order of the GPIOs should be the following:: <SDA, SCL>. The GPIO

specifier depends on the gpio controller. Required in all cases except

for "samsung,s3c2440-hdmiphy-i2c" whose input/output lines are
|
|
permanently wired to the respective client.
