libertas: move to uniform lbs_/LBS_ namespace This patch unifies the namespace of variables, functions defines and structures. It does: - rename libertas_XXX to lbs_XXX - rename LIBERTAS_XXX to lbs_XXX - rename wlan_XXX to lbs_XXX - rename WLAN_XXX to LBS_XXX (but only those that were defined in libertas-local *.h files, e.g. not defines from net/ieee80211.h) While passing, I fixed some checkpatch.pl errors too.

libertas: read SD8688 firmware status from new register The scratch pad register is used to store firmware status after firmware is downloaded and initialized. After firmware status is verified OK, the same register is used to store RX packet length. Hence the firmware status code is no longer valid afterwards. SD8688 firmware introduces a new register for firmware status which will never be overwritten. Also add scratch_reg variable to if_sdio_card structure and initialize it based on the model of the card during probe.

libertas: get SD8688 rx length with one CMD52 Usually, the 16-bit rx length is read from scratch pad registers with two CMD52 transactions: SD8385: IF_SDIO_SCRATCH_OLD (0x80fe/0x80ff) SD8686/SD8688: IF_SDIO_SCRATCH (0x34/0x35) Alternatively, SD8688 firmware offers an enhanced method for driver to read an 8-bit rx length (in units) with a single CMD52: IF_SDIO_RX_UNIT 0x43 is read one time after firmware is ready. IF_SDIO_RX_LEN 0x42 is read every time when rx interrupt is received. Signed-off-by: Bing Zhao <bzhao@marvell.com> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

libertas: add support for Marvell SD8688 chip libertas: add support for Marvell SD8688 chip Use RxPD->pkt_ptr to locate eth803 header in the packet received since SD8688/v10 firmware allows a gap between RxPD and eth803 header. Set SDIO block size to 256 for CMD53. The maximum block size for SD8688 WLAN function is set to 512 in TPLFE_MAX_BLK_SIZE. But using 512 as block size results upto 2K bytes data (4 blocks) being transferred and causes buffer overflow in firmware. Both changes above are backward compatible with earlier firmware versions for SD8385/SD8686. The SDIO_DEVICE_IDs for SD8688 chip are added in include/linux/mmc/sdio_ids.h Signed-off-by: Kiran Divekar <dkiran@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.
