2020-01-06soc: renesas: Add ARCH_R8A7795[01] for existing R-Car H3Geert Uytterhoeven1-0/+8
Despite using the same compatible values ("r8a7795"-based) because of historical reasons, R-Car H3 ES1.x (R8A77950) and R-Car H3 ES2.0+ (R8A77951) are really different SoCs, with different part numbers. Reflect this in the SoC configuration, by adding CONFIG_ARCH_R8A77950 and CONFIG_ARCH_R8A77951 as new config symbols. These are intended to replace CONFIG_ARCH_R8A7795, and will allow making support for early SoC revisions optional. Note that for now, CONFIG_ARCH_R8A7795 is retained, and just selects CONFIG_ARCH_R8A77950 and CONFIG_ARCH_R8A77951. This relaxes dependencies of other subsystems on the SoC configuration symbol, and provides a smooth transition path for config files through "make oldconfig".

2019-11-01soc: renesas: rcar-sysc: Add R8A77961 supportGeert Uytterhoeven5-13/+26
Add support for the power areas in the Renesas R-Car M3-W+ (R8A77961) SoC to the R-Car System Controller driver. R-Car M3-W+ (aka R-Car M3-W ES3.0) is very similar to R-Car M3-W (R8A77960), which allows for both SoCs to share a driver: - R-Car M3-W+ lacks the A2VC power area, so its area must be nullified, - The existing support for the SYSCEXTMASK register added in commit 9bd645af9d2a49ac ("soc: renesas: r8a7796-sysc: Fix power request conflicts") applies to ES3.0 and later only. As R-Car M3-W+ uses a different compatible value, differentiate based on that, instead of on the ES version. Based on a patch in the BSP by Dien Pham <dien.pham.ry@renesas.com>.

2019-11-01soc: renesas: Add missing check for non-zero product register addressGeert Uytterhoeven1-1/+1
If the DTB for a device with an RZ/A2 SoC lacks a device node for the BSID register, the ID validation code falls back to using a register at address 0x0, which leads to undefined behavior (e.g. reading back a random value). This could be fixed by letting fam_rza2.reg point to the actual BSID register. However, the hardcoded fallbacks were meant for backwards compatibility with old DTBs only, not for new SoCs. Hence fix this by validating renesas_family.reg before using it.

2019-10-01soc: renesas: rcar-sysc: Prepare for fixing power request conflictsGeert Uytterhoeven2-0/+19
Recent R-Car Gen3 SoCs added an External Request Mask Register to the System Controller (SYSC). This register allows to mask external power requests for CPU or 3DG domains, to prevent conflicts between powering off CPU cores or the 3D Graphics Engine, and changing the state of another power domain through SYSC, which could lead to CPG state machine lock-ups. Add support for making use of this register. Take into account that the register is optional, and that its location and contents are SoC-specific. Note that the issue fixed by this cannot happen in the upstream kernel, as upstream has no support for graphics acceleration yet. SoCs lacking the External Request Mask Register may need a different mitigation in the future. Inspired by a patch in the BSP by Dien Pham <dien.pham.ry@renesas.com>.

Currently the R-Mobile "always-on" PM Domain is implemented by returning -EBUSY from the generic_pm_domain.power_off() callback, and doing nothing in the generic_pm_domain.power_on() callback. However, this means the PM Domain core code is not aware of the semantics of this special domain, leading to boot warnings like the following on SH/R-Mobile SoCs: sh_cmt e6130000.timer: PM domain c5 will not be powered off Fix this by making the always-on nature of the domain explicit instead, by setting the GENPD_FLAG_ALWAYS_ON flag.

2018-12-06soc: renesas: rcar-sysc: Fix power domain control after system resumeGeert Uytterhoeven1-19/+9
To control power to a power domain, the System Controller (SYSC) needs the corresponding interrupt source to be enabled, but masked, to prevent the CPU from receiving it. Currently this is handled in the driver's probe() routine, and set up for every domain present, even if it will not be controlled directly by SYSC (CPU domains are powered through the APMU on R-Car Gen2 and later). On R-Car Gen3, PSCI powers down the SoC during system suspend, thus losing any configured interrupt state. Hence after system resume, power domains not controlled through the APMU (e.g. A3IR, A3VC, A3VP) fail to power up. Fix this by replacing the global interrupt setup in the probe() routine by a domain-specific interrupt setup in rcar_sysc_power(), where the domain's power is actually controlled. This brings the code more in line with the flowchart in the Hardware User's Manual.

2018-12-06soc: renesas: rcar-sysc: Merge PM Domain registration and linkingGeert Uytterhoeven1-13/+5
Commit 977d5ba4507dfe5b ("soc: renesas: rcar-sysc: Make PM domain initialization more robust") split PM Domain registration and the linking of children to their parents, to accommodate PM Domain tables that list child domains before their parents. However, this failed to realize that parent power domains must be powered up before their children anyway, and that this thus must be reflected by the order in the PM Domain tables. Revert the split, as it did not help anyway. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2018-12-06soc: renesas: rcar-sysc: Remove rcar_sysc_power_{down,up}() helpersGeert Uytterhoeven1-15/+4
Until commit 7e8a50df26f4e700 ("soc: renesas: rcar-sysc: Drop legacy handling"), the rcar_sysc_power_{down,up}() helpers were public, as they were called by the legacy (pre-DT) CPU power management code on R-Car H1 and R-Car Gen2 before. As they are just one-line wrappers around rcar_sysc_power(), it makes sense to just remove them. This also avoids a bool/helper/bool conversion in rcar_sysc_power_cpu(), where a bool is checked to call one of two helper functions, which just call rcar_sysc_power() with hardcoded boolean values again.

2018-12-06soc: renesas: r8a77990-sysc: Fix initialization order of 3DG-{A,B}Geert Uytterhoeven1-19/+4
The workaround for the wrong hierarchy of the 3DG-{A,B} power domains on R-Car E3 ES1.0 corrected the parent domains. However, the 3DG-{A,B} power domains were still initialized and powered in the wrong order, causing 3DG operation to fail. Fix this by changing the order in the table at runtime, when running on an affected SoC.

The pm-rmobile driver is really a driver for the System Controller (SYSC) found in R-Mobile SoCs. An equivalent driver for R-Car SoCs is already located under drivers/soc/renesas/.

arch/arm64/Kconfig.platforms has SoC-specific Kconfig symbols for Renesas SoCs, while other vendors have only a single Kconfig symbol. Increase consistency with other vendors by moving the SoC-specific Kconfig symbols to drivers/soc/renesas/Kconfig. Increase consistency with R-Car Gen1 and Gen2 SoCs on arm32 by introducing a family-specific Kconfig symbol for R-Car Gen3 (ARCH_RCAR_GEN3), which enables family-specific hardware features. While so far only a single family (R-Car Gen3 and derivatives) of Renesas arm64 SoCs is supported by Linux, this will make it easier to add support for other SoC families later.
