soc/tegra: pmc: Don't create fake interrupt hierarchy levels

2020-10-10T11:12:11Z

The Tegra PMC driver does ungodly things with the interrupt hierarchy, repeatedly corrupting it by pulling hwirq numbers out of thin air, overriding existing IRQ mappings and changing the handling flow of unsuspecting users. All of this is done in the name of preserving the interrupt hierarchy even when these levels do not exist in the HW. Together with the use of proper IRQs for IPIs, this leads to an unbootable system as the rescheduling IPI gets repeatedly repurposed for random drivers... Instead, let's simply mark the level from which the hierarchy does not make sense for the HW, and let the core code trim the usused levels from the hierarchy. Signed-off-by: Marc Zyngier

treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59Z

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

soc/tegra: fuse: Fix typo in APB MISC warning

The hardware block is called APB MISC, not ABP MISC, so fix the warning to use the correct name. Signed-off-by: Thierry Reding

soc/tegra: pmc: Enable PMIC wake event on Tegra210

2020-05-22T12:55:54Z

The PMIC wake event can be used to bring the system out of suspend based on certain events happening on the PMIC (such as an RTC alarm). Signed-off-by: Jon Hunter Signed-off-by: Thierry Reding

soc/tegra: fuse: Update the SoC revision attribute to display a name

2020-04-21T22:08:05Z

Currently the SoC revision attribute for Tegra devices displays the value of the enum associated with a particular revision. This is not very useful because to obtain the actual revision you need to use the tegra_revision enumeration to translate the value. It is more meaningful to display a name for the revision, such as 'A01', than the enumarated value and therefore, update the revision attribute to display a name. This change does alter the ABI, which is unfortunate, but this is more meaningful and maintable. Signed-off-by: Jon Hunter Signed-off-by: Thierry Reding

soc/tegra: fuse: Trivial clean-up of tegra_init_revision()

2020-04-21T22:07:27Z

Clean-up the tegra_init_revision() function by removing the 'rev' variable which is not needed and use the newly added helper function tegra_get_minor_rev() to get the minor revision. Signed-off-by: Jon Hunter Signed-off-by: Thierry Reding

soc/tegra: fuse: Add custom SoC attributes

2020-04-21T22:07:23Z

Add a custom SoC attribute for Tegra to expose the HIDREV register fields to userspace via the sysfs. This register provides additional details about the type of device (eg, silicon, FPGA, etc) as well as revision. Exposing this information is useful for identifying the exact device revision and device type. For Tegra devices up until Tegra186, the majorrev and minorrev fields of the HIDREV register are used to determine the device revision and device type. For Tegra194, the majorrev and minorrev fields only determine the revision. Starting with Tegra194, there is an additional field, pre_si_platform (which occupies bits 20-23), that now determines device type. Therefore, for all Tegra devices, add a custom SoC attribute for the majorrev and minorrev fields and for Tegra194 add an additional attribute for the pre_si_platform field.
