Subsystems (5)
v6 cover ARM: imx: Add Freescale LS1021A SoC and board support
This series contain the support for Freescale LS1021A CPU and LS1021A-QDS and LS1021A-TWR board.
The LS1021A SoC combines two ARM Cortex-A7 cores that have been optimized for high reliability and pack the highest level of integration available for sub-3W embedded communications processors and with a comprehensive enablement model focused on ease of programmability.
The LS1021A SoC shares IPs with i.MX family, Vybrid family and Freescale PowerPC platform.
For the detail information about LS1021A SoC, please refer to the RM doc.
---
changes in v6:
add dts patch description.
remove '-' from QDS and TWR board dts name for consistence with u-boot.
changes in v5:
remove unideal dts nodes for later add.
add X11 license to dts files.
changes in v4:
add "syscon" compatible to scfg and dcfg dts node. remove mxc_restart in the platform machine desc. remove dma_zone_size defination.
changes in v3:
rewrite scfg and dcfg binding doc description. remove sai related node leaving to the driver support.
changes in v2:
remove unused nodes.
wakeup the secondary core by IPI call to u-boot standby procedure. add dt-bindings for LS1021A SoC and platform gerenal configuration nodes.

v6 cover ARM: imx: Add Freescale LS1021A SoC and board support
In reply to Jingchang LuQuoted 11 lines · Jingchang Lu
This series contain the support for Freescale LS1021A CPU and LS1021A-QDS and LS1021A-TWR board.
The LS1021A SoC combines two ARM Cortex-A7 cores that have been optimized for high reliability and pack the highest level of integration available for sub-3W embedded communications processors and with a comprehensive enablement model focused on ease of programmability.
The LS1021A SoC shares IPs with i.MX family, Vybrid family and Freescale PowerPC platform.
Quoted 6 lines
For the detail information about LS1021A SoC, please refer to the RM doc.

changes in v6:
add dts patch description.
remove '-' from QDS and TWR board dts name for consistence with u-boot.
I'm not sure it's a good idea. The most idiomatic DTS naming schema is just <socname>-<boardname>.dts.

Many our PowerPC platforms doesn't have '-' between SoCs and board names. This becomes a project requirement when integrating in our SDK release, and I have renamed these board names internally, so I also rename them on upstream for consistence. Thanks.

Especially since this SoC has a letter in the end, its quite hard to tell what is the SoC name and what is the board name. Hence I vote for the hyphen too.
