From: Sean Wang <sean.wang@xxxxxxxxxxxx> v8 and changes since v7: - add updates per these suggestions mentioned in [1][2] - remove the hack atomic_inc(&hdev->cmd_cnt) mentioned in [2] because it should be better to be considered in the core [1] http://lists.infradead.org/pipermail/linux-mediatek/2018-August/014516.html [2] http://lists.infradead.org/pipermail/linux-mediatek/2018-August/014518.html v7 and changes since v6: - drop already applied patches - move clk_* and pm_* operation to ->open and ->close - label this driver as BT_MTKUART - make code style aligned with the other drivers and code better to read as these suggestions and fixes are mentioned in [1] [1] http://lists.infradead.org/pipermail/linux-mediatek/2018-July/014458.html v6 and changes since v5: - make btmtkuart become a separate driver. - drop already applied patches and the patch for btuart driver - refine comments in driver allowing people know that mtk extra header + length doesn't indicate a full H:4 frame, things can fragment. - enhance dt-binding document with removing mistaken added " and improve English sentence. - remove unnecessary '\n' with bt_dev_err. - refine code style. - set hdev->manufacturer as mtk id. v5 and changes since v4: - add Reviewed-by Tag from Ulf Hansson for patch 2 - remove default y in Kconfig for btmtkuart selection to avoid overkill for users which would like to have less an amount on stuff in kernel. - list header declarations in alphabetical order and add a proper blank line within. - remove unused macro. - use sizeof to calculate structure size instead of an aextra macro to hardcode. - use struct hci_dev * as input paraments for mtk_hci_wmt_sync and mtk_setup_fw for that can be reused in mtk bluetooth with other interfaces. - remove unused local variabled in mtk_btuart_recv. - remove superfluous :8 for dlen2 in struct mtk_stp_hdr definition. - give a reasonable naming for these labels and add a pm_runtime_put_noidle() in the path undoing failing pm_runtime_get_sync(). - Turn __u8 into u8 in struct mtk_stp_hdr. Really thanks for these reviews by Johan Hovold and Andy Shevchenko v4 and changes since v3: - refine patch 2 based on commit 919b7308fcc4 to allow that dev_pm_domain_attach() will return better error codes. v3 and changes since v2 * all changes happen on patch 6 - fix up SPDX license style for btmtkuart.h. - change firmware download from in ACL data to in HCI commands and then remove unused mtk_acl_wmt_sync and related code. - add a workaround replacing bad vendor event id 0xe4 with 0xff every vendor should use. - add a sanity check for mtk_hci_wmt_sync to verifying if input parameters are valid. - add an atomic_inc(&bdev->hdev->cmd_cnt) for __hci_cmd_sync_ev. - be changed to use firmware with a header called mt7622pr2h.bin. v2 and changes since v1 - Dropped patches already being applied - Rewirte the whole driver using btuart [1], and add slight extension of btuart to fit into btmtkuart driver. Beware that [1] is also pulled into one part of the series for avoiding any breakage when the patchset is being compiled. [1] btuart https://www.spinics.net/lists/linux-bluetooth/msg74918.html v1: Hi, This patchset introduces built-in Bluetooth support on MT7622 SoC. And, it should be simple to make an extension to support other MediaTek SoCs with adjusting a few of changes on the initialization sequence of the device. Before the main driver is being introduced, a few of things about power-domain management should be re-worked for serdev core and MediaTek SCPSYS to allow the Bluetooth to properly power up. Patch 2: add a generic way attaching power domain to serdev Patch 3 and 4: add cleanups with reuse APIs from Linux core Patch 5: fix a limitation about power enablement Bluetooth depends on Patch 1, 6 and 7: the major part of adding Bluetooth support to MT7622 Sean Sean Wang (3): dt-bindings: net: bluetooth: Add mediatek-bluetooth Bluetooth: mediatek: Add protocol support for MediaTek serial devices MAINTAINERS: add an entry for MediaTek Bluetooth driver .../devicetree/bindings/net/mediatek-bluetooth.txt | 35 ++ MAINTAINERS | 8 + drivers/bluetooth/Kconfig | 11 + drivers/bluetooth/Makefile | 2 + drivers/bluetooth/btmtkuart.c | 588 +++++++++++++++++++++ 5 files changed, 644 insertions(+) create mode 100644 Documentation/devicetree/bindings/net/mediatek-bluetooth.txt create mode 100644 drivers/bluetooth/btmtkuart.c -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
