soc/tegra: pmc: Prevent racing with cpuilde driver

2021-08-11T09:51:39+00:00

Both PMC and cpuidle drivers are probed at the same init level and cpuidle depends on the PMC suspend mode. Add new default suspend mode that indicates whether PMC driver has been probed and reset the mode in a case of deferred probe of the PMC driver.

ARM: tegra: Create tegra20-cpufreq platform device on Tegra30

2020-05-06T17:01:17+00:00

The tegra20-cpufreq now instantiates cpufreq-dt and Tegra30 is fully supported by that driver. Acked-by: Peter De Schrijver Tested-by: Peter Geis Tested-by: Marcel Ziswiler Tested-by: Jasper Korten Tested-by: David Heidelberg Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

ARM: tegra: Correct PL310 Auxiliary Control Register initialization

2020-05-06T16:43:24+00:00

The PL310 Auxiliary Control Register shouldn't have the "Full line of zero" optimization bit being set before L2 cache is enabled. The L2X0 driver takes care of enabling the optimization by itself. This patch fixes a noisy error message on Tegra20 and Tegra30 telling that cache optimization is erroneously enabled without enabling it for the CPU: L2C-310: enabling full line of zeros but not enabled in Cortex-A9 Cc: Signed-off-by: Dmitry Osipenko Tested-by: Nicolas Chauvet Signed-off-by: Thierry Reding

cpuidle: tegra: Squash Tegra114 driver into the common driver

2020-03-13T10:32:01+00:00

Tegra20/30/114/124 SoCs have common idling states, thus there is no much point in having separate drivers for a similar hardware. This patch moves Tegra114/124 arch/ drivers into the common driver without any functional changes. The CC6 state is kept disabled on Tegra114/124 because the core Tegra PM code needs some more work in order to support that state.

ARM: tegra: Expose PM functions required for new cpuidle driver

2020-03-13T10:22:41+00:00

The upcoming unified CPUIDLE driver will be added to the drivers/cpuidle/ directory and it will require all these exposed Tegra PM-core functions.

firmware: Move Trusted Foundations support

ARM: tegra: Set up L2 cache using Trusted Foundations firmware

2019-04-09T14:36:23+00:00

On Tegra30 L2 cache should be initialized using firmware call if CPU is running in insecure mode. Set up the required outer-cache write_sec() callback early during boot using the firmware API, it is always a NO-OP on T114+ and is NO-OP on T20/30 if Trusted Foundations firmware node isn't present in device-tree.

soc/tegra: Register SoC device

2017-08-17T14:43:13+00:00

Move this code from arch/arm/mach-tegra and make it common among 32-bit and 64-bit Tegra SoCs. This is slightly complicated by the fact that on 32-bit Tegra, the SoC device is used as the parent for all devices that are instantiated from device tree. Signed-off-by: Thierry Reding
