2016-05-09ARC: use fixed frequencies in arc_set_early_base_baud()Alexey Brodkin
UARTs usually have fixed clock so we're switching to use of constant values instead of something derived from core clock frequency. Among other things this will allow us to get rid of arc_{get|set}_core_freq() and switch to generic clock framework later on.

2016-05-09ARC: [intc-*] switch to linear domainVineet Gupta
Now that we have Timers probed from DT, don't need legacy domain This however requires mapping to be called explicitly for the IRQ which still can't (and probably never) be probed from DT such as IPI and SOFTIRQ Acked-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2016-05-09ARC: [intc-*] Do a domain lookup in primary handler for hwirq -> linux virqVineet Gupta
The primary interrupt handler arch_do_IRQ() was passing hwirq as linux virq to core code. This was fragile and worked so far as we only had legacy/linear domains. This came out of a rant by Marc Zyngier. http://lists.infradead.org/pipermail/linux-snps-arc/2015-December/000298.html Cc: Marc Zyngier <marc.zyngier@arm.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Noam Camus <noamc@ezchip.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2016-05-09ARC: irq: export some IRQs againVineet Gupta
This will be needed for switching to linear irq domain as irq_create_mapping() called by intr code needs the IRQ numbers in addition to existing usage in mcip.c for requesting the irq Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2016-05-09ARC: clocksource: DT based probeVineet Gupta
- Remove explicit clocksource setup and let it be done by OF framework by defining CLOCKSOURCE_OF_DECLARE() for various timers - This allows multiple clocksources to be potentially registered simultaneouly: previously we could only do one - as all of them had same arc_counter_setup() routine for registration - Setup routines also ensure that the underlying timer actually exists. - Remove some of the panic() calls if underlying timer is NOT detected as fallback clocksource might still be available 1. If GRFC doesn't exist, jiffies clocksource gets registered anyways 2. if RTC doesn't exist, TIMER1 can take over (as it is always present) Cc: Daniel Lezcano <daniel.lezcano@linaro.org> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
2016-05-09ARC: clockevent: DT based probeVineet Gupta
- timer frequency is derived from DT (no longer rely on top level DT "clock-frequency" probed early and exported by asm/clk.h) - TIMER0_IRQ need not be exported across arch code, confined to intc as it is property of same - Any failures in clockevent setup are considered pedantic and system panic()'s as there is no generic fallback (unlike clocksource where a jiffies based soft clocksource always exists) Acked-by: Daniel Lezcano <daniel.lezcano@linaro.org> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

2016-05-09ARC: clockevent: switch to cpu notifier for clockevent setupNoam Camus
ARC Timers so far have been handled as "legacy" w/o explicit description in DT. This poses challenge for newer platforms wanting to use them. This series will eventually help move timers over to DT. This patch does a small change of using a CPU notifier to set clockevent on non-boot CPUs. So explicit setup is done only on boot CPU (which will later be done by DT) Signed-off-by: Noam Camus <noamc@ezchip.com> [vgupta: broken off from a bigger patch] Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

2016-05-09ARC: opencode arc_request_percpu_irqVineet Gupta
- The idea is to remove the API usage since it has a subltle design flaw - relies on being called on cpu0 first. This is true for some early per cpu irqs such as TIMER/IPI, but not for late probed per cpu peripherals such a perf. And it's usage in perf has already bitten us once: see c6317bc7c5ab ("ARCv2: perf: Ensure perf intr gets enabled on all cores") where we ended up open coding it anyways - The seeming duplication will go away once we start using cpu notifier for timer setup Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

2016-05-08fq_codel: add memory limitation per queueEric Dumazet
On small embedded routers, one wants to control maximal amount of memory used by fq_codel, instead of controlling number of packets or bytes, since GRO/TSO make these not practical. Assuming skb->truesize is accurate, we have to keep track of skb->truesize sum for skbs in queue. This patch adds a new TCA_FQ_CODEL_MEMORY_LIMIT attribute. I chose a default value of 32 MBytes, which looks reasonable even for heavy duty usages. (Prior fq_codel users should not be hurt when they upgrade their kernels) Two fields are added to tc_fq_codel_qd_stats to report : - Current memory usage - Number of drops caused by memory limits # tc qd replace dev eth1 root est 1sec 4sec fq_codel memory_limit 4M .. # tc -s -d qd sh dev eth1 qdisc fq_codel 8008: root refcnt 257 limit 10240p flows 1024 quantum 1514 target 5.0ms interval 100.0ms memory_limit 4Mb ecn Sent 2083566791363 bytes 1376214889 pkt (dropped 4994406, overlimits 0 requeues 21705223) rate 9841Mbit 812549pps backlog 3906120b 376p requeues 21705223 maxpacket 68130 drop_overlimit 4994406 new_flow_count 28855414 ecn_mark 0 memory_used 4190048 drop_overmemory 4994406 new_flows_len 1 old_flows_len 177 Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Jesper Dangaard Brouer <brouer@redhat.com> Cc: Dave Täht <dave.taht@gmail.com> Cc: Sebastian Möller <moeller0@gmx.de> Signed-off-by: David S.

2016-05-08drm/msm: Drop load/unload drm_driver opsArchit Taneja
The load/unload drm_driver ops are deprecated. They should be removed as they result in creation of devices visible to userspace even before the drm_device is registered. Drop these ops and use drm_dev_alloc/register and drm_dev_unregister/unref to explicitly create and destroy the drm device in the msm platform driver's bind and unbind ops. With this in use, the drm connectors are only registered once the drm_device is registered. It also fixes the issue of stray debugfs files after the msm module is removed. With this, all the debugfs files are removed, and allows successive module insertions/removals. Signed-off-by: Archit Taneja <architt@codeaurora.org>
2016-05-08drm/msm: Centralize connector registration/unregistrationArchit Taneja
Move the drm_connector registration from the encoder(HDMI/DSI etc) drivers to the msm platform driver. This will simplify the task of ensuring that the connectors are registered only after the drm_device itself is registered. The connectors' destroy ops are made to use kzalloc instead of devm_kzalloc to ensure that that the connectors can be successfully unregistered when the msm driver module is removed. The memory for the connectors is unallocated when drm_mode_config_cleanup() is called during either during an error or during driver remove.

2016-05-08drm/msm/mdp4: Don't manage DSI PLL regulators in MDP driverArchit Taneja
The MDP4 driver tries to request and set voltages for regulators required by the DSI PLLs. Firstly, the MDP4 driver shouldn't manage the DSI regulators, this should be handled in the DSI driver. Secondly, it shouldn't try to set a fixed voltage for regulators. Voltage constraints should be specified on the regulator via DT and managed by the regulator core.

2016-05-08drm/msm/dsi: Fix regulator API abuseArchit Taneja
The voltage changing code in this driver is broken and should be removed. The driver sets a single, exact voltage on probe. Unless there is a very good reason for this (which should be documented in comments) constraints like this need to be set via the machine constraints, voltage setting in a driver is expected to be used in cases where the voltage varies at runtime. In addition client drivers should almost never be calling regulator_can_set_voltage(), if the device needs to set a voltage it needs to set the voltage and the regulator core will handle the case where the regulator is fixed voltage. If the driver simply skips setting the voltage if it doesn't have permission then it should just not bother in the first place. Originally authored by Mark Brown <broonie@kernel.org> Remove the min/max voltage data entries per SoC managed by the driver. These aren't needed as we don't try to set voltages any more.
