[PATCH v2 0/8] ARM: davinci: complete the conversion to using the reset framework

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bgolaszewski at baylibre.com>

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].

v1 -> v2:
- fixed the device tree patches the descriptions of which were mixed up
- return -EPROBE_DEFER from davinci-rproc's probe() if we can't get the
  reset provider, since it's possible that the lookup table was not yet
  registered
- made the local variable naming consistent in the davinci-rproc driver
- fixed a typo in PATCH 5/8

Bartosz Golaszewski (8):
  reset: modify the way reset lookup works for board files
  ARM: davinci: dts: make psc0 a reset provider
  ARM: davinci: dts: add a reset control to the dsp node
  clk: davinci: add a reset lookup table for psc0
  remoteproc: da8xx: add the missing retval check for clk_enable()
  remoteproc: da8xx: prepare and unprepare the clock where needed
  remoteproc: da8xx: use the reset framework
  clk: davinci: kill davinci_clk_reset_assert/deassert()
