When we enumerate second device when PMIC has been successfully detected to AXP, we got into troubles dereferencing NULL pointer. It seems we have to detect PMIC only once because pmic_id is a global variable and code doesn't expect the change of it: Two PMICs on one platform? It's impossible. Crash excerpt: [ 34.335237] BUG: kernel NULL pointer dereference, address: 0000000000000002 ... [ 35.652036] RIP: 0010:gmin_subdev_add.cold+0x32f/0x33e [atomisp_gmin_platform] So, as a quick fix make power a global variable. In next patches we move PMIC detection to be more independent from subdevices. Signed-off-by:

Instead of parsing GPIO for two exceptions inside the logic which would be trying to use the GPIO, move the init code to the routine which adds a new gmin device. Move the notes to it too, as this helps to identify where those two GPIO settings are used, explaining why they're defaulting to -1 when not found. Tested-by:

There's only one place where a subdev can be added: when the sensor driver registers it. Trying to do it elsewhere will cause problems, as the detection code needs to access the I2C bus in order to probe some things. Tested-by:

The media core has now a check if fi->pad is bigger than zero or bigger than sd->entity.num_pads, if the media controller is defined. This causes a call to g_frame_interval to return -EINVAL. Fix it by first cleaning up the struct. Tested-by:

Newer devices don't place the PMIC CLK line inside an EFI var. Instead, those are found at the _PR0 table. Add a parser for it, using info stored via the DSDT table. Tested-by:

Add support code for this driver to use ACPI power management. Yet, at least with known devices, this won't work without further changes. The rationale is that the ACPI handling code checks for the _PR? tables in order to know what is required to switch the device from power state D0 (_PR0) up to D3COLD (_PR3). The adev->flags.power_manageable is set to true if the device has a _PR0 table, which can be checked by calling acpi_device_power_manageable(adev). However, this only says that the device can be set to power off mode. At least on the DSDT tables we've seen so far, there's no _PR3 nor _PS3 (which would have a somewhat similar effect). So, using ACPI for power management won't work, except if adding an ACPI override logic somewhere. Tested-by:

The gmin_subdev_add() currently doesn't use ACPI device power management. In order to prepare for adding support for it, let's shift some things, placing the PM-related stuff at the end of the probing logic. Let's also store the current gs on a temporary var, in order to simplify the source code. Tested-by:

Right now, the driver is not doing the right thing to detect the clock like used by the sensor, at least on devices without the gmin's EFI vars. Add some notes at the code to explain why and skip the wrong value provided by the _DSM table. Signed-off-by:

The Rockchip Video Decoder driver is expecting that the values in a scaling list are in zig-zag order and applies the inverse scanning process to get the values in matrix order. Commit 0b0393d5 ("media: uapi: h264: clarify expected scaling_list_4x4/8x8 order") clarified that the values in the scaling list should already be in matrix order. Fix this by removing the reordering and change to use two memcpy. Fixes: cd33c830 ("media: rkvdec: Add the rkvdec driver") Signed-off-by:

Commit 9495b7e9 ("driver core: platform: Initialize dma_parms for platform devices") in v5.7-rc5 causes vb2_dma_contig_clear_max_seg_size() to kfree memory that was not allocated by vb2_dma_contig_set_max_seg_size(). The assumption in vb2_dma_contig_set_max_seg_size() seems to be that dev->dma_parms is always NULL when the driver is probed, and the case where dev->dma_parms has bee initialized by someone else than the driver (by calling vb2_dma_contig_set_max_seg_size) will cause a failure. All the current users of these functions are platform devices, which now always have dma_parms set by the driver core. To fix the issue for v5.7, make vb2_dma_contig_set_max_seg_size() return an error if dma_parms is NULL to be on the safe side, and remove the kfree code from vb2_dma_contig_clear_max_seg_size(). For v5.8 we should remove the two functions and move the dma_set_max_seg_size() calls into the drivers. Signed-off-by:

Commit 9495b7e9 ("driver core: platform: Initialize dma_parms for platform devices") in v5.7-rc5 added allocation of dma_parms structure to all platform devices. Then vb2_dma_contig_set_max_seg_size() have been changed not to allocate dma_parms structure and rely on the one allocated by the device core. Lets allocate the needed structure also for the devices created for the 2 MFC device memory ports. Reported-by:

Recently, MEDIA_CEC_SUPPORT became indepedent of MEDIA_SUPPORT. However, if MEDIA_SUPPORT is not enabled, MEDIA_SUPPORT_FILTER is not defined, and MEDIA_CEC_SUPPORT is thus enabled by default, which is not desirable. Fix this by adding a dependency on MEDIA_CEC_SUPPORT to the default configuration. Fixes: 46d2a3b9 ("media: place CEC menu before MEDIA_SUPPORT") Signed-off-by:

Previously, the output format was programmed as part of the ioctl() handler. However, this has two problems: 1) If there are multiple active streams with different output formats, the hardware will use whichever format was set last for both streams. Similarly, an ioctl() done in an inactive context will wrongly affect other active contexts. 2) The registers are written while the device is not actively streaming. To enable runtime PM tied to the streaming state, all hardware access needs to be moved inside cedrus_device_run(). The call to cedrus_dst_format_set() is now placed just before the codec-specific callback that programs the hardware.

Instead of keep hardcoding device-specific tables, read them directly from the ACPI BIOS, if available. This method is know to work with Asus T101HA device. the same table is also visible on EzPad devices. So, it seems that at least some BIOSes use this method to pass data about ISP2401-connected sensors. Signed-off-by: -

The hive_isp_css_custom_host_hrt.h code, together with atomisp_helper.h, provides an abstraction layer for some functions inside atomisp_compat_css20.c and atomisp_cmd.c. There's no good reason for that. In a matter of fact, after removing the abstraction, the code looked a lot cleaner and easier to understand. So, get rid of them. While here, get rid also of the udelay(1) abstraction code. Signed-off-by: -
