Enable UART-attached Bluetooth on 2015+ MacBook (Pro), v4.
I forgot to include a changelog in each individual patch in v3,
I'm making up for it now by listing the changes since both, v3 and v2.
Changes since v3:
- In patch [07/13] ("Document struct bcm_device"):
s/enable flow control/disable flow control/ to account for inverse
semantics of hci_uart_set_flow_control().
- In patch [05/13] and [09/13] ("Handle errors properly"):
Fix corner case where an unbalanced pm_runtime_disable() could occur.
- In patch [10/13] ("Support Apple GPIO handling"):
Style fix: Unroll bcm_apple_get_resources() inline stub. (Andy)
Changes since v2:
- In patch [01/13] ("Mandate presence of shutdown and device wake GPIO"):
Keep netdev indentation style. (Marcel)
- New patch [04/13] to fix an IRQ race on ->close.
- New patch [05/13] to fix an unbalanced pm_runtime_disable(). (Andy)
- New patch [06/13] to invalidate the IRQ if requesting it failed.
- New patch [08/13] to add callbacks to toggle GPIOs.
This makes the subsequent addition of Mac support less intrusive.
Replaces patch "Add helper to toggle device wake GPIO" in v2. (Andy)
- In patch [09/13] ("Handle errors properly"):
Drop redundant assignment. (Andy)
- In patch [10/13] ("Support Apple GPIO handling"):
Don't enable runtime PM on Macs for lack of usable host wake IRQ (Hans),
s/BlueTooth/Bluetooth/ in kerneldoc. (Marcel)
- Move patch "Silence IRQ printk" to end of series as it's merely
a cleanup and no longer necessary for Mac support.
- New patch [12/13] to use msleep() instead of mdelay()
after toggling device wake pin. (Andy)
- New patch [13/13] to fix sleep mode struct ordering.
- Drop incorrect patch "Enable runtime PM despite absence of IRQ". (Hans)
