2017-03-30clk: renesas: rcar-gen3-cpg: Add support for RCLK on R-Car H3 ES2.0Geert Uytterhoeven1-11/+27
Starting with R-Car H3 ES2.0, the parent of RCLK is selected using MD28. Add support for that, but retain the old behavior for R-Car H3 ES1.x and M3-W ES1.0 using a quirk. Inspired by a patch by Takeshi Kihara in the BSP. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Cc: Takeshi Kihara <takeshi.kihara.df@renesas.com>
2017-03-30clk: renesas: r8a7795: Add support for R-Car H3 ES2.0Geert Uytterhoeven1-50/+151
The Clock Pulse Generator / Module Standby and Software Reset module in R-Car H3 ES2.0 differs from ES1.x in the following areas: - More core clocks (S0D2, S0D3, S0D6, S0D8, S0D12), - Different parent clocks for AUDMAC, EtherAVB, FCP, FDP, IMR, SYS-DMAC, VIN, VSPB, VSPI, - Removal of modules CSI21, FCPCI, FCPF2, FCPVD3, FCPVI2, FDP1-2, USB3-IF1, VSPD3, VSPI2, - Addition of modules EHCI3, HS-USB-IF3, USB-DMAC3-0, USB-DMAC3-1. The goal is twofold: 1. Support both the ES1.x and ES2.0 SoC revisions in a single binary for now, 2. Make it clear which code supports ES1.x, so it can easily be identified and removed later, when production SoCs are deemed ubiquitous. This is achieved by: - Updating the clock tables for the latest revision (ES2.0), but not removing clocks that only exist on earlier revisions (ES1.x), - Detecting the SoC revision at runtime using the new soc_device_match() API, and fixing up the clocks tables to match the actual SoC revision, by: - NULLifying core and module clocks of modules that do not exist, - Reparenting module clocks that have a different parent on ES1.x. Based on R-Car Gen3 Hardware User's Manual rev. 0.53E. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
2017-03-30clk: renesas: cpg-mssr: Add support for fixing up clock tablesGeert Uytterhoeven2-0/+72
The same SoC may have different clocks and/or module clock parents, depending on SoC revision. One option is to use different sets of clock tables for each SoC revision. However, if the differences are small, it is much more space-efficient to have a single set of clock tables, and fix those up at runtime instead. Hence provide three helpers: - Two helpers to NULLify core and module clocks that do not exist on some revisions (NULLified clocks are skipped during the registration phase), - One helper to reparent module clocks that have different clock parents.

When there is no status bit, it is possible for the clock enable/disable operation to have not completed by the time the driver code resumes execution. This is due to the fact that write operations are sometimes queued and delayed internally. Doing a read ensures the write operations has completed.

2017-01-23clk: renesas: mstp: Make INTC-SYS a critical clockGeert Uytterhoeven1-0/+5
INTC-SYS is the module clock for the GIC. Accessing the GIC while it is disabled causes: Unhandled fault: asynchronous external abort (0x1211) at 0x00000000 Currently, the GIC-400 driver cannot enable its module clock for several reasons: - It does not use a platform device, so Runtime PM is not an option, - gic_of_init() runs before any clocks are registered, so it cannot enable the clock explicitly, - gic_of_init() cannot return -EPROBE_DEFER, as IRQCHIP_DECLARE() doesn't support deferred probing. Hence we have to keep on relying on the boot loader for enabling the module clock. To prevent the module clock from being disabled when the CCF core thinks it is unused, and thus causing a system lock-up, add a check to the MSTP clock driver and enable CLK_IS_CRITICAL. This will make sure the module clock is never disabled. This is a hard dependency for describing the INTC-SYS clock in DT on R-Mobile APE6 and R-Car Gen2.

2017-01-23clk: renesas: cpg-mssr: Migrate to CLK_IS_CRITICALGeert Uytterhoeven1-9/+2
When the Renesas CPG/MSSR driver was introduced, it was anticipated that critical clocks would be handled through a new CLK_ENABLE_HAND_OFF flag soon. However, CLK_ENABLE_HAND_OFF never made it upstream. Instead, commit 32b9b10961860860 ("clk: Allow clocks to be marked as CRITICAL") introduced CLK_IS_CRITICAL, a flag with slightly differing semantics. Still, it can be used to prevent e.g. the GIC module clock from being turned off, until the GIC-400 driver has full support for Runtime PM. Hence migrate the Renesas CPG/MSSR driver from CLK_ENABLE_HAND_OFF to CLK_IS_CRITICAL. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Acked-by: Stephen Boyd <sboyd@codeaurora.org>
