[PATCH net-next v6 0/4] can: cc770: add support for the Bosch CC770 and Intel AN82527

[Wolfgang Grandegger <wg@grandegger.com>]

Already since a while we have support for the Bosch CC770 and Intel
AN82527 CAN controllers in our out-of-tree Socket-CAN repository.

In the meantime I found a TQM855L board with two AN82527 on it,
which allowed me to provide and test a generic platform driver
as well.

Changes since v1:

- remove version.h includes
- some minor corrections in the ISA bus driver
- add platform header file to the driver core
- add generic platform driver
- add and update device tree nodes for tqm8xx and tqm8548

Changes since v2:

- correct license text as suggest by Oliver Hartkopp
- use the new module_platform_driver function
- provide get_berr_counter callback for cc770
- improve CAN error state change handling
- more comprehensive cc770_isa driver description

Changes since v3:

- pre-define pr_fmt()
- use KBUILD_MODNAME instead of DRV_NAME
- use ARRAY_SIZE() whenever appropriate
- use variable name "o" for message objects consistantly
- use proper error code for cc770_probe_chip
- remove unneeded member priv->open_time
- remove unnecessary masking of u8 variables (with 0xff)
- use "!skb" instead of "skb == NULL"
- CC770_MSG_MAX now limits the number of messages read in the ISR
- use "|" instead of "+" to combine bit masks
- remove return code check of platform_get_resource() in remove function
- remove postal address from GPL copyright text
- fix WARNING: __packed is preferred over __attribute__((packed))
- some more minor fixes (casts, white space, etc.)

Changes since v4:

- cc770_isa: add missing cc770 platform include

Changes since v5:

- cc770_platform: fix build issues on ARM and x86 by replacing
  in_8/out8 with ioread8/iowrite8 amd including some missing
  header files
- cc770_platform: remove trailing lines

It would be nice if somebody else could test the driver, especially
the ISA driver (I don't have hardware at hand).

Wolfgang.
