Merge tag 'clk-renesas-for-v4.10-tag2' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers into clk-next Pull Renesas clk driver updates from Geerty Uytterhoeven: - Add R-Car RST driver for obtaining mode pin state, and move the related functionality from platform code to DT, - Add r8a7743 and r8a7745 CPG Core Clock Definitions. The commits here are intermingled with arm-soc material because of the hard dependency we're breaking between mach code and driver code. We're replacing that with a driver dependency between the soc driver and the clk driver. * tag 'clk-renesas-for-v4.10-tag2' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers: (25 commits) clk: renesas: Add r8a7745 CPG Core Clock Definitions clk: renesas: Add r8a7743 CPG Core Clock Definitions clk: renesas: rcar-gen2: Remove obsolete rcar_gen2_clocks_init() clk: renesas: r8a7779: Remove obsolete r8a7779_clocks_init() clk: renesas: r8a7778: Remove obsolete r8a7778_clocks_init() ARM: shmobile: rcar-gen2: Stop passing mode pins state to clock driver ARM: shmobile: r8a7779: Stop passing mode pins state to clock driver ARM: shmobile: r8a7778: Stop passing mode pins state to clock driver clk: renesas: rcar-gen3-cpg: Remove obsolete rcar_gen3_read_mode_pins() clk: renesas: r8a7796: Obtain mode pin values from R-Car RST driver clk: renesas: r8a7795: Obtain mode pin values from R-Car RST driver clk: renesas: rcar-gen2: Obtain mode pin values using RST driver clk: renesas: r8a7779: Obtain mode pin values from R-Car RST driver clk: renesas: r8a7778: Obtain mode pin values using R-Car RST driver arm64: renesas: r8a7796 dtsi: Add device node for RST module arm64: renesas: r8a7795 dtsi: Add device node for RST module ARM: dts: r8a7794: Add device node for RST module ARM: dts: r8a7793: Add device node for RST module ARM: dts: r8a7792: Add device node for RST module ARM: dts: r8a7791: Add device node for RST module ...

This adds initial support for clocks controlled by the Resource Power Manager (RPM) processor on some Qualcomm SoCs, which use the qcom_smd_rpm driver to communicate with RPM. Such platforms are msm8916, apq8084 and msm8974. The RPM is a dedicated hardware engine for managing the shared SoC resources in order to keep the lowest power profile. It communicates with other hardware subsystems via shared memory and accepts clock requests, aggregates the requests and turns the clocks on/off or scales them on demand.

Currently the RPM/RPM-SMD clock drivers do not register the xo clocks, so we should always add factor clock. When we later add xo clocks support into the drivers, we should update this function to skip registration. By doing so we avoid any DT dependencies. Signed-off-by:

This function is passed an __iomem pointer but we use a u32 pointer instead which makes checkers like spare complain. Furthermore, "lock" is a pretty poor variable name for a string that will go into lockdep reports and the symbol isn't marked static. Cleanup all this. Acked-by:

The new pxa2xx_determine_rate() function seems lacking in a few regards: - For an exact match or no match at all, the rate is uninitialized as reported by gcc -Wmaybe-unintialized: drivers/clk/pxa/clk-pxa.c: In function 'pxa2xx_determine_rate': drivers/clk/pxa/clk-pxa.c:243:5: error: 'rate' may be used uninitialized in this function - If we get a non-exact match, the req->rate output is never set to the actual rate but remains at the requested rate. - We should not attempt to print a rate if none could be found This rewrites the logic accordingly.

The dummy_clk_set_parent function is marked as 'static' but is no longer referenced from the pxa25x clk driver after the last use of the RATE_RO_OPS() macro is gone from this file, causing a harmless build warning: In file included from drivers/clk/pxa/clk-pxa25x.c:24:0: drivers/clk/pxa/clk-pxa.h:146:12: error: 'dummy_clk_set_parent' defined but not used [-Werror=unused-function] This marks the functon as 'inline', which lets the compiler simply drop it when it gets referenced.

Rockchip RK3399 PLLs can be used in two separate modes: integral and fractional. We can select between these two modes with the unambiguously named DSMPD bit. During boot, we check all PLL settings to confirm that they match our PLL table for that frequency, and reinitialize the PLLs where they don't. The settings checked for this include the fractional divider field that is only used in fractional mode, even if we're in integral mode (DSMPD = 1) and that field has no effect. This patch changes the check to only compare the fractional divider if we're actually in fractional mode. This way, we won't reinitialize the PLL in cases where there's absolutely no reason for that, which may avoid glitching child clocks that should better not be glitched (e.g. PWM regulators).

The Kconfig currently controlling compilation of this code is: arch/arm/mach-omap2/Kconfig:config SOC_DRA7XX arch/arm/mach-omap2/Kconfig: bool "TI DRA7XX" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tags etc. since all that information is already contained at the top of the file in the comments.
