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).
