The $obj-m/$obj-y vars should be adding new modules to build, not overriding it. So, it should never use $obj-y := foo.o instead, it should use: $obj-y += foo.o Failing to do that is very bad, as it will suppress needed modules. Signed-off-by:Mauro Carvalho Chehab <mchehab@redhat.com>

The ISP clock register content is not preserved over the ISP power domain off/on cycle. Instead of setting the clock frequencies once at probe time the clock rates set up is moved to the runtime_resume handler, which is invoked after the related power domain is already enabled, ensuring the clocks are properly configured when the device is actively used. This fixes the FIMC-IS malfunctions and STREAM ON timeout errors accuring on some boards: [ 59.860000] fimc_is_general_irq_handler:583 ISR_NDONE: 5: 0x800003e8, IS_ERROR_UNKNOWN [ 59.860000] fimc_is_general_irq_handler:586 IS_ERROR_TIME_OUT Signed-off-by:

in soc_camera_close(), if ici->ops->remove() removes device firstly, and then call __soc_camera_power_off(), it has logic error. Since if remove device, it should disable subdev clk. but in __soc_camera_ power_off(), it will callback v4l2 s_power function which will read/write subdev registers to control power by i2c. and then i2c read/write will fail because of clk disable. So suggest to re-sequence two functions call. Change-Id: Iee7a6d4fc7c7c1addb5d342621eb8dcd00fa2745 Signed-off-by:

This fixes a NULL pointer deference when loading the cx88_dvb module for a Hauppauge HVR4000. The bugzilla bug report is here: https://bugzilla.kernel.org/show_bug.cgi?id=56271 The cause is that the wm8775 is optional, so even though the board info says there is one, it doesn't have to be there. Checking whether the module was actually loaded is much safer. Note that this driver is quite buggy when it comes to unloading and reloading modules. Unloading cx8800 and reloading it again will still cause a crash, most likely because either the i2c bus isn't unloaded at the right time and/or the v4l2_device_unregister isn't called at the right time.

The "sysreg" clock is required by multiple subsystems and none of the other drivers handles this clock explicitly. It is currently assumed that this clock is always on, left in its default state after system reset. Remove handling of this clock from the FIMC-IS driver to avoid breaking other subsystems.

Use clk_prepare_enable/clk_unprepare_disable instead of preparing the clocks during the driver initalization and then using just clk_disable/ clk_enable. The clock framework doesn't guarantee a clock will not get enabled during e.g. clk_set_parent if clk_prepare has been called on it. So we ensure clk_prepare() is called only when it is safe to enable the clocks, i.e. the parent clocks and the clocks' frequencies are set. It must be ensured the FIMC-IS clocks have proper frequencies before they are enabled, otherwise the whole system will hang. Signed-off-by:

MFC uses two clocks - MFC gate clock and special clock which is named as "sclk_mfc" in exynos4 and "aclk_333" in exynos5 SoC. The driver was doing just a clk_prepare on this special clock without a clk_enable call. As this sclk is the parent of gate clock, it gets prepared and enabled along with the gate clock. So there is no need for the driver to use this sclk. This patch removes the sclk usage from driver. Signed-off-by:

MFC v6 needs minimum number of output buffers to be queued for encoder depending on the stream type and profile. The patch modifies the driver so that encoding cannot be started with lesser number of OUTPUT buffers than required. This also fixes the crash happeninig during multi instance encoder-decoder simultaneous run due to memory allocation happening from interrupt context. Signed-off-by:
