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.
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].

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)
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()
