soc/tegra: pmc: Use the new reset APIs to manage reset controllers

2018-03-19T08:42:39+00:00

Make use of of_reset_control_array_get_exclusive() to manage an array of reset controllers available with the device.

soc/tegra: pmc: Pass PMC to tegra_powergate_power_up()

2018-03-08T16:02:43+00:00

tegra_powergate_sequence_power_up() makes up a struct tegra_powergate from scratch in order to reuse the same code as used by the generic PM domain implementation. However, subsequent patches will need to access the struct tegra_pmc * embedded in the powergate structure, so we need to make sure we always pass it in.

soc/tegra: pmc: MBIST work around for Tegra210

2018-03-08T16:02:24+00:00

Apply the memory built-in self test work around when ungating certain Tegra210 power domains. Signed-off-by: Peter De Schrijver Reviewed-by: Jon Hunter Tested-by: Jon Hunter Tested-by: Hector Martin Tested-by: Andre Heider Tested-by: Mikko Perttunen Signed-off-by: Thierry Reding

soc/tegra: pmc: Add Tegra194 compatibility string

2018-03-08T15:44:01+00:00

The Tegra194 PMC is mostly compatible with Tegra186, including in all currently supported features. As such, add a new compatibility string but point to the existing Tegra186 SoC data for now. Signed-off-by: Mikko Perttunen Signed-off-by: Thierry Reding

soc/tegra: Add Tegra194 SoC configuration option

2018-03-08T15:44:01+00:00

Add the configuration option to enable support for the Tegra194 system- on-chip. Signed-off-by: Mikko Perttunen Signed-off-by: Thierry Reding

soc/tegra: fuse: Explicitly request DMA channel from APB DMA driver

2017-12-21T16:04:12+00:00

Currently fuse driver requests DMA channel from an arbitrary DMA device, it is not a problem since there is only one DMA provider for Tegra20 yet, but it may become troublesome if another provider will appear. Signed-off-by: Dmitry Osipenko Acked-by: Jon Hunter Signed-off-by: Thierry Reding

soc/tegra: fuse: Fix reading registers using DMA on Tegra20

2017-12-21T16:03:49+00:00

FUSE driver doesn't configure DMA channel properly, because of it DMA transfer is never issued and tegra20_fuse_read() always return 0x0. Signed-off-by: Dmitry Osipenko Acked-by: Jon Hunter Signed-off-by: Thierry Reding

soc/tegra: pmc: Consolidate Tegra186 support

2017-12-13T12:06:44+00:00

Move Tegra186 support to the consolidated PMC driver to reduce some of the duplication and also gain I/O pad functionality on the new SoC as a side-effect. Signed-off-by: Thierry Reding

soc/tegra: pmc: Parameterize driver

2017-12-13T12:04:50+00:00

Parameterize some aspects of the driver in preparation for Tegra186 PMC support. Initially the Tegra186 driver had been split off into an extra driver, but it turns out the backwards-compatibility break isn't as bad as originally assumed, so with a little parameterization the same code can be used to keep supporting all SoC generations.

soc/tegra: fuse: Add Tegra186 chip ID support

2017-12-13T11:43:31+00:00

The register region containing chip ID information has been relocated in Tegra186 and changed in backwards-incompatible ways. Add a compatible string to allow the driver to make the distinction. Signed-off-by: Thierry Reding
