Subject[PATCH v5 0/8] ARM: davinci: complete the conversion to using the reset framework
From: Bartosz Golaszewski <>

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.

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].

[1] git:// common-clk-v9
[2] git:// reset/next
[3] topic/davinci-reset

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
- made the local variable naming consistent in the davinci-rproc driver
- fixed a typo in PATCH 5/8

v2 -> v3:
- modify PATCH 1/8: drop the provider argument from the function adding
lookup entries and instead pass the provider name to the RESET_LOOKUP
macro, return -EPROBE_DEFER if we locate a correct lookup entry but
cannot get the corresponding reset controller
- modify the reset lookup entry in psc-da850
- don't manually return -EPROBE_DEFER from davinci-rproc, instead don't
emit an error message if devm_reset_control_get_exclusive() returns
this error code

v3 -> v4:
- make index the second parameter in RESET_LOOKUP() (right after the
provider name)

v4 -> v5:
- fix a bug where the dsp_reset object correctly stored in drproc struct

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()
