2018-12-22watchdog: Add pm8916 watchdog driverLoic Poulain
The PM816 module is a versatile PMIC with many diverse functions integrated, including, a watchdog. This watchdog is subcomponent of the PON (Power On) peripheral, in the same way as pwrkey/resin buttons. It works with two timers (2-stages), the first one generates an IRQ to the main SoC (APQ8016/MSM8916), the second one performs the reset. This driver expects the following device hierarchy: [pm8916]->[pm8916-pon]->[pm8916-wdt] It uses the pm8916 regmap to access PM8916 registers.

2018-12-22macintosh: Use of_node_name_{eq, prefix} for node name comparisonsRob Herring
Convert string compares of DT node names to use of_node_name_{eq,prefix} helpers instead. This removes direct access to the node name pointer. This changes a single case insensitive node name comparison to case sensitive for "ata4". This is the only instance of a case insensitive comparison for all the open coded node name comparisons on powerpc. Searching the commit history, there doesn't appear to be any reason for it to be case insensitive. A couple of open coded iterating thru the child node names are converted to use for_each_child_of_node() instead.

Use devm_kstrdup_const() in the tegra-hsp driver. This mostly serves as an example of how to use this new routine to shrink driver code. Also use devm_kzalloc() instead of regular kzalloc() to shrink the driver even more.

2018-12-21mailbox: tegra-hsp: Add support for shared mailboxesThierry Reding
The Tegra HSP block supports 'shared mailboxes' that are simple 32-bit registers consisting of a FULL bit in MSB position and 31 bits of data. The hardware can be configured to trigger interrupts when a mailbox is empty or full. Add support for these shared mailboxes to the HSP driver. The initial use for the mailboxes is the Tegra Combined UART. For this purpose, we use interrupts to receive data, and spinning to wait for the transmit mailbox to be emptied to minimize unnecessary overhead.

2018-12-21mailbox: Allow multiple controllers per deviceMikko Perttunen
Look through the whole controller list when mapping device tree phandles to controllers instead of stopping at the first one. Each controller is intended to only contain one kind of mailbox, but some devices (like Tegra HSP) implement multiple kinds and use the same device tree node for all of them. As such, we need to allow multiple mbox_controllers per device tree node. Signed-off-by: Mikko Perttunen <mperttunen@nvidia.com> Signed-off-by: Jassi Brar <jaswinder.singh@linaro.org>
2018-12-21mailbox: Support blocking transfers in atomic contextThierry Reding
The mailbox framework supports blocking transfers via completions for clients that can sleep. In order to support blocking transfers in cases where the transmission is not permitted to sleep, add a new ->flush() callback that controller drivers can implement to busy loop until the transmission has been completed. A new mbox_flush() function can be called by mailbox consumers in atomic context to make sure a transfer has completed.
