From: Stephen Warren <swarren@xxxxxxxxxx> ((( This is V2 of a small subset of a much larger series. All the driver code in the series has been ack'd, so I'm just missing acks for the DT bindings changes, which is all I'm reposting here. The changes in V2 are minor typo-oriented changes. V1 was at: http://lists.infradead.org/pipermail/linux-arm-kernel/2013-November/211699.html ))) This series implements a common reset framework driver for Tegra, and updates all relevant Tegra drivers to use it. It also removes the custom DMA bindings and replaced them with the standard DMA DT bindings. Historically, the Tegra clock driver has exported a custom API for module reset. This series removes that API, and transitions DT and drivers to the new reset framework. The custom API used a "struct clk" to identify which module to reset, and consequently some DT bindings and drivers required clocks to be provided where they really needed just a reset identifier instead. Due to this known deficiency, I have always considered most Tegra bindings to be unstable. This series removes this excuse for instability, although I still consider some Tegra bindings unstable due to the need to convert to the common DMA bindings. Historically, Tegra DMA channels have been represented in DT using a custom nvidia,dma-request-selector property. Now that standard DMA DT bindings exist, convert all Tegra bindings, DTs, and drivers to use the standard instead. This series makes a DT-ABI-incompatible change to: - Require reset specifiers in DT where relevant. - Require standard DMA specifiers. - Remove clock specifiers from DT where they were only needed for reset. - Remove legacy DMA specifier properties. I anticipate merging this whole series into the Tegra and arm-soc trees as its own branch, due to internal dependencies. This branch will be stable and can then be merged into any other subsystem trees should any conflicts arise.
