From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx> This series converts the only user of the handcoded, mach-specific reset routines in the davinci platform to using the reset framework. Patch 1 modifies the way lookup entries are registered with the reset framework. Patches 2-4 add necessary lookups/DT-properties. Patches 5-7 convert the davinci-rproc driver to the reset framework. Patch 8 removes now dead code. Philipp: it turned out that it's indeed better to use the reset controller's device name for the entry lookup. Tested both in DT and legacy modes by booting the examples from ti-ipc-rtos recipe in meta-ti. This series applies on top of David Lechner's common-clk-v9 branch[1] with Philipp Zabel's reset/next branch[2] pulled in. It can be found in my github tree as well[3].
