2014-07-27Revert "ARC: [arcfpga] stdout-path now suffices for earlycon/console"Greg Kroah-Hartman
This reverts commit 9da433c0a0b5f71ac92dc9dca778295649675f08. Vineet writes: Could you please revert this single patch from tty-next for 3.17 as the needed core changes are not yet finalized.

2014-07-10ARC: [arcfpga] stdout-path now suffices for earlycon/consoleVineet Gupta
With recent improvements to serial/of core from Grant and Rob, stdout-path alone suffices for setting up earlycon/console. arc_uart driver is already equipped to handle that, switch the DT now.

2014-06-03ARC: [arcfpga] Early ARC UART to be only activated by cmdlineVineet Gupta
Earlier CONFIG_SERIAL_ARC_CONSOLE would unconditionally enable the legacy ARC UART based early console even if platform lacked that UART (e.g. nSIM OSCI platform). So a multi-platform image containing the 2 UART drivers won't work. Fix that by probing the driver only if "earlyprintk=ttyARC0" is present in cmdline.

2013-11-12ARC: Add perf support for ARC700 coresMischa Jonker
This adds basic perf support for ARC700 cores. Most PERF_COUNT_HW* events are supported now. Signed-off-by: Mischa Jonker <mjonker@synopsys.com> Acked-by: Peter Zijlstra <peterz@infradead.org> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

Per Grant's review comment - driver changes via tty tree Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2013-02-15ARC: [plat-arcfpga]: Enabling DeviceTree for Angel4 boardVineet Gupta
* arc-uart platform device now populated dynamically, using of_platform_populate() - applies to any other device whatsoever. * uart in turn requires incore arc-intc to be also present in DT * A irq-domain needs to be instantiated for IRQ requests by DT probed device (e.g. arc-uart) TODO: switch over to linear irq domain once all devs have been transitioned to DT Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Grant Likely <grant.likely@secretlab.ca> Cc: Arnd Bergmann <arnd@arndb.de>
