Input: bcm5974 - add support for the 2013 MacBook Air

2013-07-22T01:21:29+00:00

commit 148c1c8ad3c4170186ebe6ea5900adde27d2a0e7 upstream.

The June 2013 Macbook Air (13'') has a new trackpad protocol; four new
values are inserted in the header, and the mode switch is no longer
needed. This patch adds support for the new devices.

HID: Add support for the MacBook Pro 10,2 keyboard / touchpad

2012-10-31T09:42:33+00:00

This enables the existing drivers for keyboard and touchpad with the new
USB IDs found on the MBP 13" Reasonable Resolution (also known as the
Retina Display).

Added entries to both keyboard and mouse ignore lists.

Input: bcm5974 - Convert to MT-B

2012-09-19T17:50:22+00:00

Use of the in-kernel tracking code to convert the driver to MT-B.

With ten fingers on the pad, the in-kernel tracking adds approximately
25 us to the maximum irqsoff latency. Under normal workloads, however,
the tracking has no measurable effect.

Input: bcm5974 - Drop the logical dimensions

2012-09-19T17:50:22+00:00

The logical scale is used to produce special finger width values to
userspace, but has become an unnecessary restriction for everything
else.  Also, the bcm5974 trackpads are very accurate and work well
without hysteresis.

This patch simplifies the driver and device data by removing the
logical scale, and by moving the special synaptics code out of the
main path.  Also add the orientation range, needed in a subsequent
patch, to the device configuration.

Input: bcm5974 - Preparatory renames

2012-09-19T17:50:21+00:00

Rename touch properties to match established nomenclature, and define
the maximum number of fingers.

Input: bcm5974 - only setup button urb for TYPE1 devices

2012-09-19T17:50:21+00:00

The early generations with this trackpad used the separate mouse
interface to produce button events. With the introduction of the
button pads, this information was moved to the trackpad interface,
leaving the mouse interface unused. The driver is still setting up
both interfaces, which has not caused any problems - until now.

It turns out that without the CONFIG_USB_EHCI_TT_NEWSCHED option, the
driver may return an ENOSPC upon bt_urb submission, resulting in a
failure to open the device. This happens everytime on the MacBookPro
Retina (and likely on other mid-2012 models), but earlier MacBook
models seem to work fine.

This patch skips the bt_urb setup for TYPE2 devices, which arguably
should have been done in the first place.

USB: input: bcm5974.c: fix up dev_* messages

2012-05-04T22:33:02+00:00

Previously I had made the struct device point to the input device, but
after talking with Dmitry, he said that the USB device would make more
sense for this driver to point to.  So converted it to use that instead.

USB: bcm5974.c: remove dbg() usage

2012-05-02T04:33:05+00:00

dbg() was a very old USB-specific macro that should no longer
be used. This patch removes it from being used in the driver
and uses dev_dbg() instead.
