2018-12-06soc: renesas: rcar-sysc: Fix power domain control after system resumeGeert Uytterhoeven
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 Uytterhoeven
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 Uytterhoeven
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 Uytterhoeven
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.

Let's change the function signature to return the pointer to memory or an error pointer on failure, and take an argument that lets us return the size of the aux data read. This way we can remove the cmd_db_read_aux_data_len() API entirely and also get rid of the memcpy operation from cmd_db to the caller. Updating the only user of this code shows that making this change allows us to remove a function and put the lookup where the user is.

2018-11-14soc: qcom: cmd-db: Remove memcpy()ing from cmd_db_get_header()Stephen Boyd
The cmd_db_get_header() function is a static local function that doesn't need to copy anything from one place to another. Instead, it can just point into the region by returning pointers to what we're looking for. If we do that, we should mark what we're returning as const so that code can't modify cmd-db without an obvious cast.

The help text is visible in menuconfig, however QCOM_QMI_HELPERS is a hidden kconfig, so it is not selectable in menuconfig. Remove the help text so that it is more clear that this is intentionally a hidden kconfig.

Txn IDs created up to INT_MAX cause overflow while storing the IDs in u16 type supported by QMI header. Limit the txn IDs max value to U16_MAX to avoid overflow.

llcc_slice_getd can return a ERR_PTR code on failure. Add a IS_ERR_OR_NULL check to subsequent API calls that use struct llcc_slice_desc to guard against faults and to let the leaf drivers get away with safely using a ERR_PTR() encoded "pointer" in the aftermath of a llcc_slice_getd error.
