Subject: [PATCH 00/11] media: exynos4-is: Improve support for s5pv210 and parallel ports

This patchset improves support in the exynos4-is driver for s5pv210
platforms as well as for sensors connected to the parallel ports
and not using the CSIS device.

Fixes range from nullptr exceptions to probe fixes to JPEG fixes.

Notably, it also changes the fwnode probing of parallel port sensors
to match the binding doc.  The binding doc said port A = reg 0 and
port B = reg 1 but the driver implemented A=1 and B=2.  The only in-tree
user of parallel ports is currently Goni, which notes that it uses port
A but has reg = 1.  Also note that the sensor driver is not mainlined
despite being present.  I have left the DTS as-is.

Some patches cleaning up non-DT support are also included.

The patches have been tested on a first-gen Galaxy S GT-i900M device based
on S5PV210.  Two sensors (CE147 and S5KA3DFX, both with non-mainline
drivers), both attached to port A, were succesfully used.

Jonathan Bakker (10):
  media: exynos4-is: Remove static driver data for S5PV210 FIMC variants
  media: exynos4-is: Fix nullptr when no CSIS device present
  media: exynos4-is: Correct missing entity function initialization
  media: exynos4-is: Improve support for sensors with multiple pads
  media: exynos4-is: Properly set JPEG options when not using CSIS
  media: exynos4-is: Add support for multiple sensors on one port
