memory: mvebu-devbus: Fix missing clk_disable_unprepare in mvebu_devbus_probe()

2022-12-27T08:54:32Z

The clk_disable_unprepare() should be called in the error handling of devbus_get_timing_params() and of_platform_populate(), fix it by replacing devm_clk_get and clk_prepare_enable by devm_clk_get_enabled.

memory: tegra: Remove clients SID override programming

2022-12-27T08:52:33Z

On newer Tegra releases, early boot SID override programming and SID override programming during resume is handled by bootloader. In the function tegra186_mc_program_sid() which is getting removed, SID override register of all clients is written without checking if secure firmware has allowed write on it or not. If write is disabled by secure firmware then it can lead to errors coming from secure firmware and hang in kernel boot. Also, SID override is programmed on-demand during probe_finalize() call of IOMMU which is done in tegra186_mc_client_sid_override() in this same file. This function does it correctly by checking if write is permitted on SID override register. It also checks if SID override register is already written with correct value and skips re-writing it in that case.

Pull drm updates from Dave Airlie: "The biggest highlight is that the accel subsystem framework is merged. Hopefully for 6.3 we will be able to line up a driver to use it. In drivers land, i915 enables DG2 support by default now, and nouveau has a big stability refactoring and initial ampere support, AMD includes new hw IP support and should build on ARM again. There is also an ofdrm driver to take over offb on platforms it's used. Stuff outside my tree, the dma-buf patches hit a few places, the vc4 firmware changes also do, and i915 has some interactions with MEI for discrete GPUs. I think all of those should have been acked/reviewed by relevant parties.

memory: tegra: Add API for retrieving carveout bounds

2022-11-25T15:14:58Z

On Tegra234 NVDEC firmware is loaded from a secure carveout, where it has been loaded by a bootloader. When booting NVDEC, we need to tell it the address of this firmware, which we can determine by checking the starting address of the carveout. As such, add an MC API to query the bounds of carveouts, and add related information on Tegra234. Signed-off-by: Mikko Perttunen Acked-by: Krzysztof Kozlowski Signed-off-by: Thierry Reding
