Subject: [PATCH 00/14] Remove legacy sdma code for dt booting omaps
Date: Mon, 16 Dec 2019 16:19:11 -0800 [thread overview]
Message-ID: <20191217001925.44558-1-tony@atomide.com> (raw)
Hi all,
This series finally removes the legacy sdma code for omaps booting with
devicetree. The legacy sdma code is still left for omap1, but makes
further work a bit easier.
We do the removal of legacy sdma code with the following steps:
- Prepare for platform data removal by probing sdma with device tree
data for the interconnect target module
- Drop unused code and legacy interrupt code for omap2 and later
- Update dmaengine driver to use device tree match data and add
missing features
- Allocate logical channels directly in the dmaengine driver
- Drop legacy platform init and data
The patches are against v5.5-rc1, and need the following fixes:
2c81f0f6d3f5 ("bus: ti-sysc: Fix iterating over clocks")
e709ed70d122 ("bus: ti-sysc: Fix missing reset delay handling")
93c60483b5fe ("bus: ti-sysc: Fix missing force mstandby quirk handling")
90bdfa0b05e3 ("ARM: OMAP2+: Fix ti_sysc_find_one_clockdomain to check for to_clk_hw_omap")
To make testing easier, I've also pushed out a testing branch at [0][1].
Regards,
Tony
