2019-05-15ARM: Add workaround for I-Cache line size mismatch between CPU coresMarek Szyprowski6-0/+47
Some big.LITTLE systems have mismatch of I-Cache line size between LITTLE and big cores. This patch adds workaround for proper I-Cache support on such systems. Without it, some code (typically self-modifying) might suffer from random SIGILL failures. Similar workaround exists for ARM64 architecture, added by commit 116c81f427ff ("arm64: Work around systems with mismatched cache line sizes").

This fixes build error with tizen_odroid_defconfig related to missing MTD symbols required by exynos5433-asv.c driver. The Exynos5433 ASV driver has dependency on MTD, to avoid inheriting this dependency by the Exynos5422 ASV driver split Exynos ASV drivers into ARM and ARM64 parts, similarly as it is done for the PMU. This also has an advantage that we don't need to include ARM ASV drivers on ARM64 SoCs and we can build only ARM ASV drivers for ARM SoCs.

2019-03-19drm/exynos/mixer: fix MIXER shadow registry synchronisation codeAndrzej Hajda1-44/+66
MIXER on Exynos5 SoCs uses different synchronisation method than Exynos4 to update internal state (shadow registers). Apparently the driver implements it incorrectly. The rule should be as follows: - do not request updating registers until previous request was finished, ie. MXR_CFG_LAYER_UPDATE_COUNT must be 0. - before setting registers synchronisation on VSYNC should be turned off, ie. MXR_STATUS_SYNC_ENABLE should be reset, - after finishing MXR_STATUS_SYNC_ENABLE should be set again. The patch hopefully implements it correctly.

2019-03-19ARM: dts: exynos: Increase minimal ACLK400_DISP1 frequency on Exynos542xMarek Szyprowski1-1/+1
ACLK400_DISP1 bus feeds some internal buses of the display subsystem, some of which are also related to TV/Mixer hardware modules. When that bus is set to 120MHz, Exynos Mixer is not able to properly handle two XRGB display planes at FullHD-60MHz. DMA underrun happens, which in turn might result in reading data out of the configured buffer, what causes IOMMU page fault and kernel panic. This change fixes the following IOMMU fault, observed, when 2 Mixer planes were enabled: exynos-sysmmu 14650000.sysmmu: 14450000.mixer: PAGE FAULT occurred at 0x20fe9000 ------------[ cut here ]------------ kernel BUG at ../drivers/iommu/exynos-iommu.c:450!

2019-03-08ASoS: samsung: odroid: Fix clock configuration for 44100 sample rateSylwester Nawrocki1-2/+2
After commit fbeec965b8d1c ("ASoC: samsung: odroid: Fix 32000 sample rate handling") due to clock rounding error CODEC master clock frequency is being set to 20070401 Hz instead of 22579000 Hz. This results in too fast actual sample rate for fs=44100, e.g. 2 kHz tone has really 3555 Hz frequency (2000 Hz * 20070401/22579000 * 2). Fix this by increasing correction passed to clk_set_rate() to take into account inaccuracy of EPLL frequency properly.

To fix this we derive the secondary platform device name from the primary device name. The secondary device name will now be <primary_dev_name>-sec instead of fixed "samsung-i2s-sec". The fixed platform_device_id table entry is removed as the secondary device name is now dynamic and device/driver matching is done through driver_override.

The audio root clock will be configured appropriately only for the first stream. As the hardware is limited to same sample rate on both interfaces we need to disallow streams with different sample rates. It is done by this patch by returning error in FE hw_params if there is already active stream running with different sample rate.

2019-03-04ASoC: samsung: i2s: Prevent potential NULL platform data dereferenceSylwester Nawrocki1-12/+15
When np is NULL i2s_pdata could also be NULL but i2s_pdata is now being dereferenced without proper check. Fix this and shorten the error message so we don't exceed 80 characters limit.

2019-03-04ASoC: samsung: i2s: Simplify pri_dai, sec_dai pointers usageSylwester Nawrocki1-4/+3
If the probe call is on the primary DAI we can use 'other' in place of i2s->sec_dai, if the probe call is on the secondary DAI we can use 'i2s' in place of other->sec_dai. While at it fix one whitespace issue.

2019-03-04ASoC: samsung: Specify DMA channel names through custom DMA configSylwester Nawrocki4-11/+7
This is a part of conversion of Samsung platforms to use the custom DMA config for specifying DMA channel names, in addition to passing custom DMA device for the secondary CPU DAI's "PCM" component for some variants of the I2S controller. We also don't set the SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME any more as setting it wouldn't allow to specify DMA channels through the custom DMA config.

2019-03-04ASoC: samsung: i2s: Get rid of a static spinlockSylwester Nawrocki1-7/+9
This patch makes the spinlock serializing access to the primary/secondary PCM a per I2S controller lock, rather than a global one. There is no need to have a global lock across multiple I2S controllers in the SoC.

2019-03-04ASoC: samsung: odroid: Add support for secondary CPU DAISylwester Nawrocki1-36/+95
This patch adds DPCM links in order to support the secondary I2S interface. For the secondary PCM interface to be actually available one more entry should be added to the sound-dai property in sound/cpu node in DT. The changes in driver are done in a way so we are backwards compatible with existing DTS/DTB, i.e. if the cpu sound-dai property contains only one entry only one PCM will be registered.
