| * misc: sram: extend usage of reserved partitionsVladimir Zapolskiy2015-10-181-8/+188
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds functionality to operate on reserved SRAM partitions described in device tree file. Two partition properties are added, "pool" and "export", the first one allows to share a specific partition for usage by a kernel consumer in the same manner as it is done for the whole SRAM device, and "export" property provides access to some SRAM area from userspace over sysfs interface. Practically it is possible to specify both properties for an SRAM partition, however simultaneous access from a kernel consumer and from userspace is not serialized, but still the combination may be useful for debugging purpose. The change opens the following scenarios of SRAM usage: * updates in a particular SRAM area specified by offset and size are done by bootloader, then this information is utilized by the kernel, * a particular SRAM area is rw accessed from userspace, the stored data is persistent on soft reboots, * a device driver secures SRAM area for its purposes, * etc. Note, strictly speaking the added optional properties describe policy of SRAM usage, rather than hardware, but here the policy mostly resembles flash partitions in devicetree, which is undoubtedly a very popular option but it does not describe hardware.

Instead, this patch add pdata field to struct gpio_extcon_data. Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>

| | | * extcon: arizona: Don't disable debounce for inverted jacksCharles Keepax2015-09-221-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whilst the jack is connected we disable the jack detection debounce to ensure as quick as possible a detection of jack removal. However, it is only safe to disable the jack debounce whilst the jack is connected if using the micd clamp or the jack is not inverted. Otherwise spurious interrupts might be generated when we re-enable the debounce.

| | | * extcon: arizona: Use the micd_clamp for interrupts if it is availableCharles Keepax2015-09-221-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we only use the microphone clamp IRQ if GPIO5 is being used as a second jack detection pin. But we should be using it on any system where the clamp is available. This patch updates the driver to do so.
