From: Jasmin Jessich <jasmin@xxxxxx> This is now the V2 version of the patch series with preserved author and little checkpatch fixes. I also combined some patches which needs to be applied at once to. Changes from v1 to v2: - Preserved authorship of original author. - All patches tested with checkpatch.pl (no errors). - Patch "Set maximum cxd2099 block size to 512" is now part of patch "Fixed buffer mode", because this needs to be applied together. - Patch "Removed useless printing in cxd2099 driver" is now split into a part which is already upstream and an additional one. - Rebased to media_tree/master. These patch series implement a block read/write interface to the en50221 CAM control functions. The origin of this patches can be found in the Digital Devices Git on https://github.com/DigitalDevices/dddvb maintained by Ralph Metzler <rjkm@xxxxxxxxxxxxxx> . The relevant changes concerning dvb-core/dvb_ca_en50221.c/.h and cxd2099/cxd2099.c/.h have been extracted from the mentioned repository by Daniel Scheller <d.scheller@xxxxxxx> and committed to his branch on https://github.com/herrnst/dddvb-linux-kernel/tree/mediatree/master-cxd2099 I split the patch set in smaller pieces for easier review, fixed code style issues in cxd2099/cxd2099.c/.h and dvb_ca_en50221.c (checkpatch.pl) and tested the resulting driver on my hardware with the DD DuoFlex CI (single) card. I tested if the CAM communication is working with VDR: vdr: [2414] CAM 1: module ready vdr: [2414] CAM 1: AlphaCrypt, 01, 4A20, 4A20 vdr: [2414] CAM 1: system ids: 0D95 0648 1702 1722 1762 4A20 0500 0B00 0100 1833 1834 0D05 0D22 vdr: [2414] CAM 1: replies to QUERY - multi channel decryption (MCD) possible vdr: [2414] CAM 1: supports multi transponder decryption (MTD) vdr: [2414] CAM 1: activating MTD support vdr: [2405] CAM 1: ready, master (AlphaCrypt) Please note, that the block read/write functionality is already implemented in the currently existing cxd2099/cxd2099.c/.h driver, but deactivated. The existing code in this driver is also not functional and has been updated by the working implementation from the Digital Devices Git. Additionally to the block read/write functions, I merged also two patches in the en50221 CAM control state machine, which were existing in the Digital Devices Git. This are the first two patches of this series. There is another patch series coming "Fix coding style in en50221 CAM functions" which fixes some of the style issues in dvb-core/dvb_ca_en50221.c/.h, based on this patch series. I will send this after this series has been accepted.
