Revert "media: atomisp: keep the ISP powered on when setting it" · 0d6db851

Mauro Carvalho Chehab authored Jul 19, 2020

changeset d0213061a501 ("media: atomisp: fix mask and shift operation on ISPSSPM0")
solved the existing issue with the IUNIT power on code.

So, the driver can now use the right code again.

This reverts commit 95d1f398.

media: atomisp: fix mask and shift operation on ISPSSPM0 · 23988c97

Colin Ian King authored Jul 16, 2020

Currently the check on bits 25:24 on ISPSSPM0 is always 0 because
the mask and shift operations are incorrect. Fix this by shifting
by MRFLD_ISPSSPM0_ISPSSS_OFFSET (24 bits right) and then masking
with RFLD_ISPSSPM0_ISPSSC_MASK (0x03) to get the appropriate 2 bits
to check.

Addresses-Coverity: ("Operands don't affect result")

media: atomisp: move system_local consts into a C file · 85ebb8eb

Mauro Carvalho Chehab authored Jul 19, 2020

Instead of declaring all those consts everywhere when the
headers are included, just place them on a single place.

This change shuts up lots of warnings when built with W=1:

Right now, there are two versions of system_global.h headers.

Both share a lot of common code. There are some ISP2401 specific
types on one of the headers, but it doesn't conflict with the
ISP2400 ones.

Also, the common code is identical.

So, remove code duplication by moving such code into a
common header.

Mauro Carvalho Chehab authored Jul 18, 2020

There is an abstraction at the code in order to support
32 or 64 bits address/data length. However, for all
Atom chipsets supported by this version, the size is fixed.

So, cleanup the mess, removing the uused code and placing
the data sizes on a single place.

The end goal is to completely remove those local/global
headers, replacing them by some ISP-version dependent struct,
in order for the driver to decide what version it would need
in runtime.

media: atomisp: Make pointer to PMIC client global · 2e31e6f8

Andy Shevchenko authored Jun 26, 2020

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]

PMIC detection to be more independent from subdevices.

media: atomisp: move CCK endpoint address to generic header · 5f55dd54

Andy Shevchenko authored Jun 26, 2020

IOSF MBI header contains a lot of definitions, such as
end point addresses of IPs. Move CCK address from AtomISP driver
to generic header.

While here, drop unused one.

media: atomisp: place all gpio parsing together · 79317baa

Mauro Carvalho Chehab authored Jun 21, 2020

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.

media: atomisp: split add from find subdev · 2b5b3221

Mauro Carvalho Chehab authored Jun 21, 2020

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.

media: atomisp: fix call to g_frame_interval · d6ad1c9b

Mauro Carvalho Chehab authored Jun 21, 2020

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.

Newer devices don't place the PMIC CLK line inside an EFI

Add a parser for it, using info stored via the DSDT table.

media: atomisp: Prepare sensor support for ACPI PM · d6697288

Mauro Carvalho Chehab authored Jun 14, 2020

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.

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.

media: rkvdec: Fix H264 scaling list order · 2630e1bb

Jonas Karlman authored May 22, 2020

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.
