2018-05-14media: rc: decoders do not need to check for transitionsSean Young3-19/+0
Drivers should never produce consecutive pulse or space raw events. Should that occur, we would have bigger problems than this code is trying to guard against. Note that we already log an error should a driver misbehave. Signed-off-by: Sean Young <sean@mess.org> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc ti-sysc driver related changes for omap variants This series improves the ti-sysc interconnect target module driver to the point where a most of SoC can be booted with interconnect target module data configured in device tree instead of legacy platform data. The related device tree changes need some more work though, and can wait for v4.19. Also some drivers using nested interconnects like DSS need more work. We can now remove the unused pm-noop code that is not doing anything any longer. And we can now initialize things for PM and display pdata later to prepare things for using ti-sysc driver. We also need to add some more quirk handling so we can boot both with platform data and dts data. * tag 'omap-for-v4.18/ti-sysc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: bus: ti-sysc: Show module information for suspend if DEBUG is enabled bus: ti-sysc: Tag sdio and wdt with legacy mode for suspend bus: ti-sysc: Detect UARTs for SYSC_QUIRK_LEGACY_IDLE quirk on omap4 bus: ti-sysc: Detect omap4 type timers for quirk bus: ti-sysc: Add initial support for external resets bus: ti-sysc: Improve suspend and resume handling bus: ti-sysc: Tag some modules resource providers for noirq suspend bus: ti-sysc: Add handling for clkctrl opt clocks bus: ti-sysc: Make child clock alias handling more generic bus: ti-sysc: Handle simple-bus for nested children ARM: OMAP2+: Make display related init into device_initcall ARM: OMAP2+: Initialize SoC PM later ARM: OMAP2+: Only probe SDMA via ti-sysc if configured in dts ARM: OMAP2+: Use signed value for sysc register offsets ARM: OMAP2+: Allow using ti-sysc for system timers ARM: OMAP2+: Drop unused pm-noop Signed-off-by: Olof Johansson <olof@lixom.net>

2018-04-20media: rc: mce_kbd decoder: fix race conditionSean Young2-7/+18
The MCE keyboard sends both key down and key up events. We have a timeout handler mce_kbd_rx_timeout() in case the keyup event is never received; however, this may race with new key down events from occurring. The race is that key down scancode arrives and key down events are generated. The timeout handler races this and generates key up events straight afterwards. Since the keyboard generates scancodes every 100ms, most likely the keys will be repeated 100ms later, and now we have new key down events and the user sees duplicate key presses.

2018-04-20media: rc: mce_kbd decoder: fix stuck keysSean Young1-0/+2
The MCE Remote sends a 0 scancode when keys are released. If this is not received or decoded, then keys can get "stuck"; the keyup event is not sent since the input_sync() is missing from the timeout handler.

2018-04-20media: rc: mce_kbd decoder: low timeout values cause double keydownsSean Young1-5/+7
The mce keyboard repeats pressed keys every 100ms. If the IR timeout is set to less than that, we send key up events before the repeat arrives, so we have key up/key down for each IR repeat. The keyboard ends any sequence with a 0 scancode, in which case all keys are cleared so there is no need to run the timeout timer: it only exists for the case that the final 0 was not received.

2018-04-20media: rc: per-protocol repeat period and minimum keyup timerSean Young2-28/+30
Each IR protocol has its own repeat period. We can minimise the keyup timer to be the protocol period + IR timeout. This makes keys less "sticky" and makes IR more reactive and nicer to use. This feature was previously attempted in commit d57ea877af38 ("media: rc: per-protocol repeat period"), but that did not take the IR timeout into account, and had to be reverted.

2018-04-20media: rc: set timeout to smallest value required by enabled protocolsSean Young13-7/+47
The longer the IR timeout, the longer the rc device waits until delivering the trailing space. So, by reducing this timeout, we reduce the delay for the last scancode to be delivered. Note that the lirc daemon disables all protocols, in which case we revert back to the default value.

As warned by smatch: drivers/media/rc/st_rc.c:110 st_rc_rx_interrupt() warn: this loop depends on readl() succeeding If something goes wrong at readl(), the logic will stay there inside an IRQ code forever.

2018-04-16ARM: OMAP2+: Drop unused pm-noopTony Lindgren1-14/+3
Looks like these functions don't do anything in the mainline kernel so we can just drop it. Note that we must now also remove ir-rx51 pdata as it relies on the dummy platform data that does not do anything. And ir-rx51 is calling a pdata callback that doesn't do anything without checking if it exists first. For configuring device specific minimal latencies, the interface to use is pm_qos_add_request(). For an example, see what was done in commit 9834ffd1ecc3 ("ASoC: omap-mcbsp: Add PM QoS support for McBSP to prevent glitches"). I've added some comments to ir-rx51 so people using it can add pm_qos support and test it.
