2013-04-04arm: zynq: Move timer to generic locationMichal Simek
Move zynq timer out of mach folder to generic location and enable it. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2013-04-04arm: zynq: Do not use xilinx specific function namesMichal Simek
Remove all xilinx specific names from the driver because this is generic driver for cadence ttc. xttc->ttc ttcps->ttc ... No functional changes in this driver. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2013-04-04arm: zynq: Move timer to clocksource interfaceMichal Simek
Use clocksource timer initialization. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2013-04-04arm: zynq: Use standard timer bindingMichal Simek
Use cdns,ttc because this driver is Cadence Rev06 Triple Timer Counter and everybody can use it without xilinx specific function name or probing. Also use standard dt description for timer and also prepare for moving to clocksource initialization. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
2013-01-28arm: zynq: timer: Set clock_event cpumaskSoren Brinkmann
The timers are common to both A9 cores, so let's set the clock event struct's cpumask accordingly, to all possible CPUs. Signed-off-by: Soren Brinkmann <soren.brinkmann@xilinx.com> Tested-by: Josh Cartwright <josh.cartwright@ni.com>
2013-01-28arm: zynq: timer: Fix comment styleSoren Brinkmann
Fixing multi line comment style at two locations. Signed-off-by: Soren Brinkmann <soren.brinkmann@xilinx.com> Tested-by: Josh Cartwright <josh.cartwright@ni.com>
2013-01-28arm: zynq: timer: Remove redundant #includesSoren Brinkmann
Some #includes are implicitly included through others, some are just not needed. Signed-off-by: Soren Brinkmann <soren.brinkmann@xilinx.com> Tested-by: Josh Cartwright <josh.cartwright@ni.com>
2013-01-28arm: zynq: timer: Align columnsSoren Brinkmann
Aligning the columns in a block of #defines, so that the values are starting in the same colum on every line. Signed-off-by: Soren Brinkmann <soren.brinkmann@xilinx.com> Tested-by: Josh Cartwright <josh.cartwright@ni.com>

2013-01-28arm: zynq: timer: Remove unnecessary register writeSoren Brinkmann
Acknowedging an interrupt requires to read the interrupt register only. The write was only required to work around a bug in the QEMU implementation of the TTC, which is fixed.

2013-01-28arm: zynq: timer: Replace PSS through PSSoren Brinkmann
The acronym PSS is deprecated by Xilinx. The correct term, which is also used in Xilinx documentation is PS (processing system). This is just a search and replace: - s/PSS/PS/g - s/pss/ps/g Signed-off-by: Soren Brinkmann <soren.brinkmann@xilinx.com> Tested-by: Josh Cartwright <josh.cartwright@ni.com>
2012-11-21ARM: zynq: remove TTC early mappingJosh Cartwright
Now that the TTC driver has proper support for DT bindings, it is not necessary for the registers to be mapped early. They will be mapped during clock initialization using of_iomap(). Remove the early mapping. In addition, remove the extraneous zynq_soc.h include from the timer driver. Signed-off-by: Josh Cartwright <josh.cartwright@ni.com> Tested-by: Michal Simek <michal.simek@xilinx.com>
2012-11-14ARM: zynq: add clk binding support to the ttcJosh Cartwright
Add support for retrieving TTC configuration from device tree. This includes the ability to pull information about the driving clocks from the of_clk bindings. Signed-off-by: Josh Cartwright <josh.cartwright@ni.com> Acked-by: Michal Simek <michal.simek@xilinx.com>
2012-11-05ARM: zynq: move arm-specific sys_timer out of ttcJosh Cartwright
Move the sys_timer definition out of ttc driver and make it part of the common zynq code. This is preparation for renaming and COMMON_CLK support. Signed-off-by: Josh Cartwright <josh.cartwright@ni.com> Tested-by: Michal Simek <michal.simek@xilinx.com>
2011-06-20ARM: Xilinx: Adding Xilinx board supportJohn Linn
The 1st board support is minimal to get a system up and running on the Xilinx platform. This platform reuses the clock implementation from plat-versatile, and it depends entirely on CONFIG_OF support. There is only one board support file which obtains all device information from a device tree dtb file which is passed to the kernel at boot time. Signed-off-by: John Linn <john.linn@xilinx.com>
