Replace with globally

[media] s5p-mfc: Add support for MFC v8 available in Exynos 5433 SoCs

2016-11-30T11:22:07+00:00

Exynos5433 SoC has MFC v8 hardware module, but it has more complex clock hierarchy, so a new compatible is added. Signed-off-by: Marek Szyprowski Signed-off-by: Sylwester Nawrocki Signed-off-by: Mauro Carvalho Chehab

[media] s5p-mfc: Rework clock handling

2016-11-30T11:21:30+00:00

This patch changes the code for handling clocks. Now clocks are defined per each device variant, what is a preparation for adding support for Exynos 5433 MFC V8, which has more clocks than all previous versions. Also use devm_clk_get() to simplify cleanup path. Signed-off-by: Marek Szyprowski Signed-off-by: Sylwester Nawrocki Signed-off-by: Mauro Carvalho Chehab

[media] s5p-mfc: Don't keep clock prepared all the time

2016-11-30T11:20:39+00:00

This patch moves preparation of clocks from s5p_mfc_init_pm() (driver probe) to s5p_mfc_power_on() (start of device operation). This change will allow to use runtime power usage optimization on newer Samsung Exynos platforms (for example Exynos 5433).

[media] s5p-mfc: Kill all IS_ERR_OR_NULL in clocks management code

2016-11-30T11:20:00+00:00

After commit "s5p-mfc: Fix clock management in s5p_mfc_release function" all clocks related functions are called only when MFC device is really available, so there is no additional check needed for NULL gate clocks. This patch simplifies the code and kills IS_ERR_OR_NULL macro usage. Signed-off-by: Marek Szyprowski Signed-off-by: Sylwester Nawrocki Signed-off-by: Mauro Carvalho Chehab

[media] s5p-mfc: Remove dead conditional code

2016-11-30T11:19:17+00:00

CONFIG_PM is always enabled on Exynos platforms, so remove dead code related to early development of MFC driver on platform without PM support. Signed-off-by: Marek Szyprowski Signed-off-by: Sylwester Nawrocki Signed-off-by: Mauro Carvalho Chehab

[media] s5p-mfc: Ensure that clock is disabled before turning power off

2016-11-30T11:17:18+00:00

Move clock disabling before turning power off. This will enable later to add calls to clk_prepare/unprepare in the s5p_mfc_power_off() function to avoid keeping clocks prepared all the time when driver is bound.

[media] s5p-mfc: Remove special clock rate management

2016-11-30T11:16:54+00:00

The maximum rate of special clock depends on SoC variant and should be set in device tree via assigned-clock-rates property, so remove the code which forces special clock to 200MHz. Signed-off-by: Marek Szyprowski Signed-off-by: Sylwester Nawrocki Signed-off-by: Mauro Carvalho Chehab

[media] s5p-mfc: Use printk_ratelimited for reporting ioctl errors

2016-11-30T11:16:23+00:00

Some applications don't check error codes from QBUF/DQBUF ioctls, so don't spam kernel log with errors if they fall into endless loop trying to queue next buffer after a failure. Signed-off-by: Marek Szyprowski Signed-off-by: Sylwester Nawrocki Signed-off-by: Mauro Carvalho Chehab

[media] s5p-mfc: Set DMA_ATTR_ALLOC_SINGLE_PAGES

2016-11-30T11:15:45+00:00

We do video allocation all the time and we need it to be fast. Plus TLB efficiency isn't terribly important for video. That means we want to set DMA_ATTR_ALLOC_SINGLE_PAGES. See also the previous change (commit 14d3ae2efeed "ARM: dma-mapping: Use DMA_ATTR_ALLOC_SINGLE_PAGES hint to optimize allocation"). [m.szyprowski: rebased patch onto v4.9-rc1 and adapted changes to latest videbuf2 changes, this simplifies code changes to only set proper dma attribute flag and comment the reason for it, added commit id of arch/arm/mm patch] Signed-off-by: Douglas Anderson Signed-off-by: Marek Szyprowski Signed-off-by: Sylwester Nawrocki Signed-off-by: Mauro Carvalho Chehab
