Subject: [PATCHv4 0/4] Lost key-up interrupt handling for omap4-keypad

Hi,

This series updates omap4-keypad to disable unused long interrupts, and
implements the missing parts for the lost key-up interrupt quirk as
described in the silicon errata pdf. It also simplifies the probe to
use devm.

Regards,

Tony


Changes since v3:

- Use PM runtime to check the last pressed key is not stuck

- Simplify probe with devm

Changes since v2:

- Drop bogus level change, that already comes from device tree

- Scan keyboard in two phases and simplify using a bitmask

- Use mod_delayed_work and cancel_delayed_work_sync for the quirk

Tony Lindgren (4):
  Input: omap4-keypad - disable unused long interrupts
  Input: omap4-keypad - scan keys in two phases and simplify with
    bitmask
  Input: omap4-keypad - use PM runtime to check keys for errata
  Input: omap4-keypad - simplify probe with devm
