The following set of patches were tested on an i.MX6 multi-core platform.

Patches 1 to 4 were tested using a Bluetooth BCSP UART connection at 115.2kbps and 4Mbps. The fixes were needed because the i.MX6 UART driver caused spinlock deadlocks with the HCI TTY layer.

Patch 5 improves the i.MX6 UART driver for use with kdb.

Patch 1: serial: imx: remove unneeded imx_transmit_buffer() from imx_start_tx() Patch 2: serial: imx: remove uart_write_wakeup() from imx_transmit_buffer() Patch 3: serial: imx: avoid spinlock recursion deadlock
Patch 4: serial: imx: move imx_transmit_buffer() into imx_txint() Patch 5: serial: imx: clean up imx_poll_get_char()

The patches are based off 3.15-rc4.

Given the rather confusing threads based on these patches, I don't know what to apply.

Dean, can you respin what patches you want applied

Well, we think patches #1-#4 are correct and should be applied, but Huang has the opinion that this is fixed already in the BT stack. If Huang doesn't change his mind, then let's drop #1-#4.

Patch #5 addresses an other topic and therefore should be resent, then.

Best regards

Dirk
