22541828 - soc/tegra: fuse: Drop Kconfig dependency on TEGRA20_APB_DMA

Wed, 23 Sep 2020 00:34:21 +0000

soc/tegra: fuse: Drop Kconfig dependency on TEGRA20_APB_DMAThe DMA subsystem could be entirely disabled in Kconfig and then theTEGRA20_APB_DMA option isn't available too. Hence kernel configurationfails if DMADEVICES Kconfig option is disabled due to the unsatisfiabledependency.The FUSE driver isn't a critical driver and currently it only providesNVMEM interface to userspace which isn't known to be widely used, andthus, it's fine if FUSE driver fails to load.Let's remove the erroneous Kconfig dependency and let the FUSE driver tofail the probing if DMA is unavailable.Fixes: 19d41e5e9c68 ("soc/tegra: fuse: Add APB DMA dependency for Tegra20")Reported-by: Necip Fazil Yildiran Link: https://bugzilla.kernel.org/show_bug.cgi?id=209301Signed-off-by: Dmitry Osipenko List of files: /linux-6.15/drivers/soc/tegra/Kconfig

fc2f151d - soc/tegra: cbb: Add driver for Tegra234 CBB 2.0

Wed, 11 May 2022 20:16:50 +0000

soc/tegra: cbb: Add driver for Tegra234 CBB 2.0Adding driver to handle errors from CBB version 2.0 which is used inTegra234 SoC. The driver prints debug information about failedtransaction on receiving interrupt from the error notifier. The errornotifier collates the interrupts from various error monitor blocks andpresents a single interrupt to the SoC interrupt controller.For timeout errors, the driver also does the lookup to find timed outclients and prints their client ID. Drivers for hardware that needs tobe reset on timeout will have to call BPMP from the client IP's driver.BPMP firmware will also clear the timeout bit after resetting the IPso that next transactions are send to them after reset.Signed-off-by: Sumit Gupta Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/soc/tegra/Kconfig

soc/tegra: cbb: Add CBB 1.0 driver for Tegra194Adding driver to handle errors from Control Backbone (CBB) which aregenerated due to illegal accesses. CBB 1.0 is used in Tegra194 SoCs.When an error is reported from a NOC within CBB, the driver prints debuginformation about failed transaction like Error Code, Error Description,Master, Address, AXI ID, Cache, Protection, Security Group etc. It thencauses system crash using BUG_ON() or call WARN() based on whether theerror type is fatal or not.Signed-off-by: Sumit Gupta Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/soc/tegra/Kconfig

f880ee9e - soc/tegra: pmc: Add core power domain

Tue, 01 Jun 2021 02:31:17 +0000

soc/tegra: pmc: Add core power domainNVIDIA Tegra SoCs have multiple power domains, each domain correspondsto an external SoC power rail. Core power domain covers vast majority ofhardware blocks within a Tegra SoC. The voltage of a power domain shouldbe set to a level which satisfies all devices within the power domain.Add support for the core power domain which controls voltage state of thedomain. This allows us to support system-wide DVFS on Tegra20-210 SoCs.The PMC powergate domains now are sub-domains of the core domain, thisrequires device-tree updating, older DTBs are unaffected and will continueto work as before.Tested-by: Peter Geis # Ouya T30Tested-by: Paul Fertser # PAZ00 T20Tested-by: Nicolas Chauvet # PAZ00 T20 and TK1 T124Tested-by: Matt Merhar # Ouya T30Signed-off-by: Dmitry Osipenko Reviewed-by: Ulf Hansson [treding@nvidia.com: squash lockdep class removal patch]Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/soc/tegra/Kconfig

Thissounds like it could be handle by a generic voltage balancer, but the COREvoltage scaling isn't implemented in any of the upstream drivers yet.It will take quite some time and effort to hook up voltage scaling forall of the drivers, hence we will use a custom coupler that will managethe CPU voltage scaling for the starter.Signed-off-by: Dmitry Osipenko Acked-By: Peter De Schrijver Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/soc/tegra/Kconfig
