* ARM: zynq: Fix W=1 dtc 1.4 warningsMichal Simek2016-11-161-1/+1
| | | | | | | | | | | | | | The patch removes these warnings reported by dtc 1.4: Warning (unit_address_vs_reg): Node /pmu has a reg or ranges property, but no unit name Warning (unit_address_vs_reg): Node /fixedregulator@0 has a unit name, but no reg property Warning (unit_address_vs_reg): Node /memory has a reg or ranges property, but no unit name Signed-off-by: Michal Simek <michal.simek@xilinx.com> Reviewed-by: Julia Cartwright <julia@ni.com> Series-to: arm-soc
* ARM: zynq: Use earlycon instead of earlyprintkMichal Simek2016-02-251-1/+1

* ARM: dts: zynq: replace gpio-key,wakeup with wakeup-source propertySudeep Holla2015-12-141-2/+2
| | | | | | | | | | | | | | | | Though the keyboard driver for GPIO buttons(gpio-keys) will continue to check for/support the legacy "gpio-key,wakeup" boolean property to enable gpio buttons as wakeup source, "wakeup-source" is the new standard binding. This patch replaces the legacy "gpio-key,wakeup" with the unified "wakeup-source" property in order to avoid any futher copy-paste duplication.

* arm: dts: zynq: Move crystal freq. to board levelPeter Crosthwaite2014-12-011-0/+4
| | | | | | | | | | | | | | The fact that all supported boards use the same 33MHz crystal is a co-incidence. The Zynq PS support a range of crystal freqs so the hardcoded setting should be removed from the dtsi. Re-implement it on the board level. This prepares support for Zynq boards with different crystal frequencies (e.g. the Digilent ZYBO).

The purpose of the created zynq-7000.dtsi file is to describe the hardware common to all Zynq 7000-based boards. Also, get rid of the zynq-ep107 device tree, since it is not hardware anyone can purchase. Add a zc702 dts file based on the zynq-7000.dtsi.
