From 741268adb34061c28d8236dd67217f0df580c930 Mon Sep 17 00:00:00 2001 From: "tjiang@codeaurora.org" Date: Tue, 16 Nov 2021 12:48:49 +0800 Subject: [PATCH] Bluetooth: btusb: re-definition for board_id in struct qca_version The board ID should be split into two bytes. The 1st byte is chip ID, and the 2nd byte is platform ID. For example, board ID 0x010A, 0x01 is platform ID. 0x0A is chip ID. we have several platforms, and platform IDs are continuously added. We would not distinguish different chips if we get these mixed up. Platform ID: 0x00 is for Mobile 0x01 is for X86 0x02 is for Automotive 0x03 is for Consumer electronic Signed-off-by: Tim Jiang Signed-off-by: Marcel Holtmann --- drivers/bluetooth/btusb.c | 15 +++++++++++++-- 1 file changed, 13 insertions(+), 2 deletions(-) diff --git a/drivers/bluetooth/btusb.c b/drivers/bluetooth/btusb.c index a092c98..d5d5e85 100644 --- a/drivers/bluetooth/btusb.c +++ b/drivers/bluetooth/btusb.c @@ -2886,7 +2886,8 @@ struct qca_version { __le32 rom_version; __le32 patch_version; __le32 ram_version; - __le16 board_id; + __u8 chip_id; + __u8 platform_id; __le16 flag; __u8 reserved[4]; } __packed; @@ -3075,7 +3076,17 @@ static void btusb_generate_qca_nvm_name(char *fwname, size_t max_size, u16 flag = le16_to_cpu(ver->flag); if (((flag >> 8) & 0xff) == QCA_FLAG_MULTI_NVM) { - u16 board_id = le16_to_cpu(ver->board_id); + /* The board_id should be split into two bytes + * The 1st byte is chip ID, and the 2nd byte is platform ID + * For example, board ID 0x010A, 0x01 is platform ID. 0x0A is chip ID + * Currently we have several platforms, and platform IDs are continuously added. + * Platform ID: + * 0x00 is for Mobile + * 0x01 is for X86 + * 0x02 is for Automotive + * 0x03 is for Consumer electronic + */ + u16 board_id = (ver->chip_id << 8) + ver->platform_id; const char *variant; switch (le32_to_cpu(ver->ram_version)) { -- 2.7.4
