[PATCH v3 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.

Patches 1-3 add necessary lookups/DT-properties.

Patches 4-6 fix issues found in the remoteproc davinci driver.

Patch 7 converts 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

v2 -> v3:
- reworded the commit messages (s/remoteproc: da8xx/remoteproc\/davinci/)
- call clk_disable_unprepare() if reset_control_deassert() fails in
  da8xx_rproc_start()
- added a patch fixing the S_IRUGO checkpatch warning, since we're
  already modifying this driver anyway
- added a temp variable for code brevity in da8xx_rproc_stop()
- removed patch 1/8 (already applied to reset/next)

Bartosz Golaszewski (8):
  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/davinci: add the missing retval check for clk_enable()
  remoteproc/davinci: prepare and unprepare the clock where needed
  remoteproc/davinci: use octal permissions for module_param()
  remoteproc/davinci: use the reset framework
  clk: davinci: kill davinci_clk_reset_assert/deassert()
