* Input: adp5588-keypad - fix NULL dereference in adp5588_gpio_add()Dmitry Torokhov2010-08-031-29/+37
| | | | | | | | | | | | | | | | | The kpad structure is assigned to i2c client via i2s_set_clientdata() at the end of adp5588_probe(), but in adp5588_gpio_add() we tried to access it (via dev_get_drvdata! which is not nice at all) causing an oops. Let's pass pointer to kpad directly into adp5588_gpio_add() and adp5588_gpio_remove() to avoid accessing driver data before it is set up. Also split out building of gpiomap into a separate function to clear the logic. Reported-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

* Input: i8042 - reset keyboard controller wehen resuming from S2RDmitry Torokhov2010-07-211-24/+41
| | | | | | | | | | | Some laptops, such as Lenovo 3000 N100, require keyboard controller reset in order to have touchpad operable after suspend to RAM. Even if box does not need the reset it should be safe to do so, so instead of chasing after misbehaving boxes and grow DMI tables, let's reset the controller unconditionally.

* Input: synaptics - set min/max for finger widthChris Bagwell2010-07-201-1/+1
| | | | | | | | | | | | | Reporting this will allow GUI config apps to correctly scale width sensitive config values (such as palm detect) to correct range. Current user apps are detecting kernels min/max=0/0 and making an assumption that it means 0/16 or 0/15. Synaptics touchpad interface guides show 4/15 are correct values but driver forces to 0 when no fingers on touchpad.

* Input: synaptics - only report width on hardware that supports itChris Bagwell2010-07-201-2/+6
| | | | | | | | | | | | | | | | | | | Synaptics devices report fixed value of 5 for finger/palm widths on devices that do not support capability and driver further hardcodes to 5. Stop reporting this fixed value when its not supported since its not useful. This will aid applications so they can better auto-enable support for multi-touch emulation and palm detection logic using finger width only for devices that support width detection. I can find no applications that currently require existence on ABS_TOOL_WIDTH. Since only synaptics and bcm input devices currently support this tool, it seems they must handle it gracefully.

* Input: introduce MT event slotsHenrik Rydberg2010-07-163-43/+129
| | | | | | | | | | | | | | | | | | | | | With the rapidly increasing number of intelligent multi-contact and multi-user devices, the need to send digested, filtered information from a set of different sources within the same device is imminent. This patch adds the concept of slots to the MT protocol. The slots enumerate a set of identified sources, such that all MT events can be passed independently and selectively per identified source. The protocol works like this: Instead of sending a SYN_MT_REPORT event immediately after the contact data, one sends an ABS_MT_SLOT event immediately before the contact data. The input core will only emit events for slots with modified MT events. It is assumed that the same slot is used for the duration of an initiated contact.

* Input: xpad - remove mouse buttons and axes for dance padsChristoph Fritz2010-07-131-44/+63
| | | | | | | | | | | | | | | Dance pads don't have any axes/sticks, only buttons for directions. For example buttons like left+right will get triggered at once, an axis can't handle this anyway. So this patch adds a module parameter named "sticks_to_null" for unknown devices. A known dance pad makes use of it by changing to a new mapping-option named DANCEPAD_MAP_CONFIG. Other tested devices may follow by adding this mapping-option too. Some buttons of xpad-devices are addressing mouse-buttons instead of gamepad-buttons. This gets fixed too.

* Input: ads7846 - extend the driver for ads7845 controller supportAnatolij Gustschin2010-07-031-37/+135
| | | | | | | | | | | | | | | | | | ADS7845 is a controller for 5-wire touch screens and somewhat different from 7846. It requires three serial communications to accomplish one complete conversion. Unlike 7846 it doesn't allow Z1-/Z2- position measurement. The patch extends the ads7846 driver to also support ads7845. The packet struct is extended to contain needed command and conversion buffers. ads7846_rx() and ads7846_rx_val() now differentiate between 7845 and 7846 case. ads7846_probe() is modified to setup ads7845 specific command and conversion messages and to switch ads7845 into power-down mode, since this is needed to be prepared to respond to pendown interrupts.

This behavior is different then the non-accelerated path and for pkts over a bonded vlan. For example, vlanx -> bond0 -> ethx will be dropped in the vlan path and not delivered to any packet handlers at all. However, bond0 -> vlanx -> ethx and bond0 -> ethx will be delivered to handlers that match the exact dev, because the VLAN path checks the real_dev which is not a slave and netif_recv_skb() doesn't drop frames but only delivers them to exact matches. This patch adds a sk_buff flag which is used for tagging skbs that would previously been dropped and allows the skb to continue to skb_netif_recv(). Here we add logic to check for the deliver_no_wcard flag and if it is set only deliver to handlers that match exactly. This makes both paths above consistent and gives pkt handlers a way to identify skbs that come from inactive slaves. Without this patch in some configurations skbs will be delivered to handlers with exact matches and in others be dropped out right in the vlan path. I have tested the following 4 configurations in failover modes and load balancing modes. # bond0 -> ethx # vlanx -> bond0 -> ethx # bond0 -> vlanx -> ethx # bond0 -> ethx | vlanx -> -- Signed-off-by: John Fastabend <john.r.fastabend@intel.com> Signed-off-by: David S.

That's how MPC8313 Reference Manual describes RCTRL_TS_ENABLE bit: Timestamp incoming packets as padding bytes. PAL field is set to 8 if the PAL field is programmed to less than 8. Must be set to zero if TMR_CTRL[TE]=0. I see that the commit above sets this bit, but it doesn't handle TMR_CTRL. Manfred probably had this bit set by the firmware for his boards. But obviously this isn't true for all boards in the wild. Also, I recall that Freescale BSPs were explicitly disabling the timestamping because of a performance drop. For now, the best way to deal with this is just disable the timestamping, and later we can discuss proper device tree bindings and implement enabling this feature via some property.
