media: atomisp: register first the preview devnode
The atomisp currenyl registers 5 pairs of devices each one
for one different run_mode, plus one for "ACC". The only
one that behaves like a normal V4L2 device is the preview
one. The others are doing weird things, and perhaps are
using some proprietary extensions to the API.
Change the device order to start with the preview one,
e. g:
/dev/video0: ATOMISP ISP PREVIEW output
/dev/video1: ATOMISP ISP CAPTURE output
/dev/video2: ATOMISP ISP VIEWFINDER output
/dev/video3: ATOMISP ISP VIDEO output
/dev/video4: ATOMISP ACC

media: atomisp: set per-device's default mode
The atomisp driver originally used the s_parm command to
initialize the run_mode type to the driver. So, before start
setting up the streaming, s_parm should be called.
So, even having 5 "normal" video devices, one meant to be used
for each type, the run_mode was actually selected when
s_parm is called.
Without setting the run mode, applications that don't call
VIDIOC_SET_PARM with a custom atomisp parameters won't work, as
the pipeline won't be set:
atomisp-isp2 0000:00:03.0: can't create streams
atomisp-isp2 0000:00:03.0: __get_frame_info 1600x1200 (padded to 0) returned -22
However, commit
8a7c5594c020 ("media: v4l2-ioctl: clear fields in s_parm")
broke support for it, with a good reason, as drivers shoudn't be
extending the API for their own purposes.
So, as an step to allow generic apps to use this driver, put
the device's run_mode in preview after open.
After this patch, using v4l2grab starts to work on preview
mode (/dev/video2):
$ v4l2grab -f YUYV -x 1600 -y 1200 -d /dev/video2 -n 1 -u
$ feh out000.pnm
So, let's just setup the default run_mode that each video devnode
should assume, setting it at open() time.

media: atomisp: report colorspace information
While different sensors could have different colorspaces, the
colorspace V4L2 support didn't exist by the time atomisp driver
was written. So, the sensors won't have any data about that.
So, let's report what Asus T101HA uses (ov2680 sensor).
It may require further changes, if other sensors used on this
driver have different colorspaces.

media: atomisp: properly implement g_fmt
The current logic only initializes pipe->pix after setting up a
pipeline - e. g. after start streaming.
While it makes sense to get the format of the pipeline, when
it is set, this breaks support for generic applications, as they
rely on getting the current sensor format (which is usually the
highest resolution format).
So, implement a call to the sensor's get_fmt, when this is called
before setting up a pipeline.

Changeset
374d62e7aa50 ("media: v4l2-subdev: Verify v4l2_subdev_call() pad config argument")
added an extra verification for a pads parameter for enum mbus

Such change broke atomisp, because now the V4L2 core

Microsoft Surface 3 does not describe CsiPort/CsiLanes in DSDT [1] or
EFI, or at least not desctibed in the forms the current atomisp driver
expects. This results in the default values (port: 0 lanes: 1) to be
used, which does not work.
So, define them ourselves in the driver.
The user-facing camera is AR0330 (2-lane) and the world-facing camera
is OV8835 (4-lane).
According to the portconfigs definition in atomisp_csi_lane_config()
[atomisp_v4l2.c]:
} portconfigs[] = {
/* Tangier/Merrifield available lane configurations */
{ 0x00, { 4, 1, 0 } }, /* 00000 */
{ 0x01, { 3, 1, 0 } }, /* 00001 */
{ 0x02, { 2, 1, 0 } }, /* 00010 */
{ 0x03, { 1, 1, 0 } }, /* 00011 */
{ 0x04, { 2, 1, 2 } }, /* 00100 */

};
4-lane camera is always connected to the PRIMARY (port1) port [2]. In
this case, 2-lane camera can be connected to the only SECONDARY (port0)
port.

The intel-aero atomisp has `#if defined(IS_ISP_2400_SYSTEM)` [1]. It is
to be defined in the following two places [2]:
- css/hive_isp_css_common/system_global.h
- css/css_2401_csi2p_system/system_global.h
and the former file is to be included on ISP2400 devices, too. So, it
is to be defined for both ISP2400 and ISP2401 devices.
Because the upstreamed atomisp driver now supports only ISP2400 and
ISP2401, just remove the ISP version test again. This matches the other
upstream commits like
3c0538fbad9f ("media: atomisp: get rid of most

While here, moved the comment for define GP_ISEL_TPG_MODE to the

## `isys_stream_descr->polling_mode` case
This does not exist on the intel-aero atomisp. This is because it is
based on css version irci_stable_candrpv_0415_20150521_0458.
On the other hand, the upstreamed atomisp is based on the following css
version depending on the ISP version using ifdefs:
- ISP2400: irci_stable_candrpv_0415_20150521_0458
- ISP2401: irci_master_20150911_0724
The `isys_stream_descr->polling_mode` usage was added on updating css
version to irci_master_20150701_0213 [3].
So, it is not a ISP version specific thing, but css version specific
thing. Because the upstreamed atomisp driver uses irci_master_20150911_0724
for ISP2401, re-add the ISP version check for now.
I say "for now" because ISP2401 should eventually use the same css
version with ISP2400 (i.e., irci_stable_candrpv_0415_20150521_0458)

media: atomisp: use IA_CSS_ERROR() for error messages in sh_css_mipi.c
Some debug messages for error cases (messages contain "error: ") use
IA_CSS_DEBUG_TRACE_PRIVATE debug level. This causes these error messages
not to appear unless users raise debug output level to 7 or higher (using
module parameter, dbg_level=7).
So, use IA_CSS_DEBUG_ERROR debug level (dbg_level=1) instead considering
that these are error messages. There is already a macro IA_CSS_ERROR()
for this use case. Let's use it. It automatically appends "error: " at
the beginning and a newline to a message. Therefore, we can remove them
from these messages.
While here, remove the unnecessary newline from one IA_CSS_ERROR()
occurrence in the same file.

media: atomisp: fix inverted error check for ia_css_mipi_is_source_port_valid()
The function ia_css_mipi_is_source_port_valid() returns true if the port
is valid. So, we can't use the existing err variable as is.
To fix this issue while reusing that variable, invert the return value
when assigning it to the variable.

media: atomisp: do not use err var when checking port validity for ISP2400
Currently, the `port >= N_CSI_PORTS || err` checks for ISP2400 are always
evaluated as true because the err variable is set to `-EINVAL` on
declaration but the variable is never used until the evaluation.
Looking at the diff of commit
3c0538fbad9f ("media: atomisp: get rid of
most checks for ISP2401 version"), the `port >= N_CSI_PORTS` check is
for ISP2400 and the err variable check is for ISP2401. Fix this issue
by adding ISP version test there accordingly.

media: atomisp: fix punit_ddr_dvfs_enable() argument for mrfld_power up case
When comparing with intel-aero atomisp [1], it looks like
punit_ddr_dvfs_enable() should take `false` as an argument on mrfld_power
up case.
Code from the intel-aero kernel [1]:
int atomisp_mrfld_power_down(struct atomisp_device *isp)
{
[...]
/*WA:Enable DVFS*/
if (IS_CHT)
punit_ddr_dvfs_enable(true);
int atomisp_mrfld_power_up(struct atomisp_device *isp)
{
[...]
/*WA for PUNIT, if DVFS enabled, ISP timeout observed*/
if (IS_CHT)
punit_ddr_dvfs_enable(false);
This patch fixes the inverted argument as per the intel-aero code, as
well as its comment. While here, fix space issues for comments in
atomisp_mrfld_power().
Note that it does not seem to be possible to unify the up/down cases for
punit_ddr_dvfs_enable(), i.e., we can't do something like the following:
if (IS_CHT)
punit_ddr_dvfs_enable(!enable);
because according to the intel-aero code [1], the DVFS is disabled
before "writing 0x0 to ISPSSPM0 bit[1:0]" and the DVFS is enabled after
"writing 0x3 to ISPSSPM0 bit[1:0]".
