This patch series cleans up the Broadcom Cygnus device tree files and makes it more consistent with the rest of Broadcom iProc device tree files. This patch series also enables various peripherals on Cygnus boards.

This patch enables touchscreen support on bcm958300k and bcm958305k.
Touchscreen is connected to these boards through the bcm9hmidc daughter
card

| Message-ID | <q9RfQ-2nh-19@gated-at.bofh.it> |
| In reply to | #1227490 |
This patch cleans up Cygnus DT files and makes the format consistent
with the rest of Broadcom iProc based SoCs.
Changes include:
- Put core components into "core" node of type "simple-bus"
- Put all other peripherals into "soc" node of type "simple-bus"
- Move aliases into bcm-cygnus.dtsi to avoid duplications in all dts
files
- Ordered all device nodes under buses based on their base register
addresses
- Remove unused PCI I/O resource
- Use label instead of full path to reference device nodes in dts
files

Sorry for not > picking that up earlier. Sure! I'll break them up into individual patches as follows: - Put core components into "core" node of type "simple-bus" - Put all other peripherals into "soc" node of type "simple-bus" - Move aliases into bcm-cygnus.dtsi to avoid duplications in all dts files - Ordered all device nodes under buses based on their base register addresses - Remove unused PCI I/O resources - Use label instead of full path to reference device nodes in dts files Thanks!
