Subject: [PATCH v4 0/8] ARM: davinci: complete the conversion to using the reset framework
Date: Fri, 23 Mar 2018 14:04:47 +0100 [thread overview]
Message-ID: <20180323130455.11470-1-brgl@bgdev.pl> (raw)
From: Bartosz Golaszewski <bgolaszewski@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
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)
