2019-06-21media: mtk-vcodec: remove unneeded proxy functionsAlexandre Courbot9-52/+17
We were getting the codec interface through a proxy function that does not bring anything compared to just accessing the interface definition directly, so just do that. Also make the decoder interfaces const.

2019-06-21media: mtk-vcodec: avoid unneeded pointer-to-long conversionsAlexandre Courbot10-46/+46
The interface used to communicate with the firmware casts pointers into unsigned longs and back again in order to store private references, all of this for pointers that remain purely in the kernel. Replace these unsigned longs with void pointers to make the code a bit sturdier and easier to follow. Also simplify some interfaces by removing arguments that could be infered from others.

2019-06-21media: vimc: Makefile: file cleanupAndré Almeida3-17/+3
Remove redundant Makefile rules (vimc_capture-objs, ...). Stop exposing vimc-{common, streamer} as modules, since there's no use case where they would be individually added/removed from Vimc. As consequence, remove MODULE_ macros from vimc-{common, streamer}. `-objs` is fitted for building host programs, change to `-y`, more straightforward for device drivers.

2019-06-21media: s5p-mfc: Make additional clocks optionalMarek Szyprowski1-0/+5
Since the beginning the second clock ('special', 'sclk') was optional and it is not available on some variants of Exynos SoCs (i.e. Exynos5420 with v7 of MFC hardware). However commit 1bce6fb3edf1 ("[media] s5p-mfc: Rework clock handling") made handling of all specified clocks mandatory. This patch restores original behavior of the driver and fixes its operation on Exynos5420 SoCs.

2019-06-05media: aspeed: refine interrupt handling logicJae Hyun Yoo1-3/+4
There are cases that interrupt bits are cleared by a 500ms delayed work which causes unnecessary irq calls. Also, the current interrupt handler returns IRQ_HANDLED always but it should return IRQ_NONE if there is any unhandled interrupt. So this commit refines the interrupt handling logic to fix these issues.

2019-06-05media: aspeed: remove checking of VE_INTERRUPT_CAPTURE_COMPLETEJae Hyun Yoo1-8/+4
VE_INTERRUPT_CAPTURE_COMPLETE and VE_INTERRUPT_COMP_COMPLETE are not set at the same time but the current interrupt handling mechanism of this driver doesn't clear the interrupt flag until both two are set, and this behavior causes unnecessary interrupt handler calls. In fact, this driver provides JPEG format only so taking care of the VE_INTERRUPT_COMP_COMPLETE is enough for getting compressed image frame so this commit gets rid of the VE_INTERRUPT_CAPTURE_COMPLETE checking logic to simplify the logic. Handling of VE_INTERRUPT_CAPTURE_COMPLETE could be added back later when it's actually needed.

2019-06-05media: aspeed: reduce noisy log printing outsJae Hyun Yoo1-5/+5
Currently, this driver prints out too much log messages when a mode change happens, video turned off by screen saver and etc. Actually, all cases are reported to user space properly. Also, these are not critical errors but recoverable things, so this commit changes the log level of some noisy printing outs.

Video Engine has a dedicated interrupt line so this driver doesn't need to use IRQF_SHARED flag so remove it. Also, it'd be good for following what Thomas recommended in the IRQF_ONESHOT support patch like below: "Note that for now IRQF_ONESHOT cannot be used with IRQF_SHARED to avoid complex accounting mechanisms."

2019-06-05media: aspeed: change irq to threaded irqJae Hyun Yoo1-2/+3
Differently from other Aspeed drivers, this driver calls clock control APIs in interrupt context. Since ECLK is coupled with a reset bit in clk-aspeed module, aspeed_clk_enable will make 10ms of busy waiting delay for triggering the reset and it will eventually disturb other drivers' interrupt handling. To fix this issue, this commit changes this driver's irq to threaded irq so that the delay can be happened in a thread context.

Currently, this driver calls clk_prepare and clk_unprepare from interrupt context too but these should be called from sleepable context only. To fix this issue, this commit splits out clk_enable/disable and clk_prepare/unprepare, and it places clk_prepare/unprepare calls into the module probe/remove function.
